Pet Allergies? Why Regular AC Maintenance is Your Secret Weapon

How AC Maintenance Protects Both Your Allergies and Your Furry Friends

Western societies have a greater love for pets than most of the modern world; we even allow pets to live inside with us. They feel like family members and can be so expressive. Dogs and some cats can be lovable, faithful, and always ready to greet family members after separation.

Between 65% and 70% of American homes are also homes to a dog or a cat, totaling at least 94 million dogs and cats. Pet allergies are also the third leading allergy for Americans. That means 15% to 23% of pet owners also have pet allergies.

If you have pet allergies, but just cannot do without your furry family member, consider partnering with your heating and cooling system to reduce the number of airborne allergens. Consider these AC maintenance steps.

7 Essential AC Maintenance Tips for Pet Owners with Allergies

1 Clean as Often as Necessary

Every time you dust, vacuum, and mop, you are forever removing the accumulation of pet hair and flakes of skin from surfaces. Clean bedding and any furniture that the pet commonly lies on. The protein that causes allergies also exists in saliva, urine, and feces, so carefully make a regular clean sweep. How often? That might depend on the breed of your pet.

2 Groom Your Pet Regularly

Bathing dogs regularly and keeping fur trim will reduce the volume of hair and dander. Cats generally groom themselves and do not appreciate bathing in water. Whatever your breed of animal requires, do not skip the grooming appointments.

3 Change Your Air Filter as Often as Needed

The normal schedule for air filter changes is quarterly, once every three months. Homeowners are encouraged to schedule reminders to prompt timely air filter changes. If you have a pet and an allergy to your pet, consider more frequent filter changes, perhaps as often as a monthly replacement. Air filters collect pet hair and dander. Replacing the filter reduces the allergens in the air each time it is changed.

4 Prevent Male Dogs From “Using” the Condenser Unit

Male dogs are not particular about what object they choose for urination, so a condenser unit is as good as a tree. However, urine is very corrosive and can damage the network of tubes in the condenser.

5 Dogs and Cats are Very Adaptable When It Comes to Temperature Variations

A common approach to cost savings is to reduce heating and cooling needs by making changes to the thermostat while the family is away. The temperature setting can be reduced by 10 degrees during the heating season and raised by 10 degrees during the cooling season. This reduces the number of heating and cooling cycles needed while no humans are home. Pets can readily adapt to such temperature changes, as long as water is available, especially during the cooling season.

6 If Allergies are Particularly Severe, Consider an Air Purifier

Purifiers are available in various sizes, from room-sized to whole-house versions. Air purifiers have multiple filtration components, including a charcoal filter to remove odors and gases. Room-sized purifiers can be placed in a bedroom for the person with severe allergies or near the dog/cat’s bedding.

7 Make Sure to Maintain Your System for Everyone’s Safety

AC maintenance is the best way to keep a heating and cooling system working efficiently and keep it running as long as possible. Should the air conditioner or furnace fail to work, family members can escape the heat or cold by going to work, school, or shopping. Dogs and cats do not necessarily have this option. While they can adapt to slight temperature changes, staying in extremely hot or cold conditions is not healthy. Routine AC maintenance is a way to keep your home’s cooling and heating system working efficiently and providing the best indoor air quality possible.

Why Repeat Breakdown Costs Show You Need Regular AC Maintenance

The Homeowner’s Guide to AC Maintenance: Ending the Cycle of Yearly Repairs

As a homeowner, it is very frustrating to go through the inconvenience of an air conditioner breakdown, wait for the technician to arrive and make the repair, only to experience the same discomfort and incur the same cost the next year. Such repeat performance issues are also expensive, costing hundreds or thousands of dollars.

What can be done about this occurrence?

Understanding what can cause repeat repairs
Understanding how to avoid these issues in the future

Short Cycling: How System Sizing Impacts Your AC Maintenance

If a home has an oversized air conditioner system, it can lead to repeated problems. An oversized air conditioner cools a home too quickly, a condition called “short cycling”. That might sound good, but the air conditioner is also removing humidity from the air. A short cycle does not have sufficient time to remove moisture from the air inside the home. A short cycle also forces the air conditioner to cycle more often. Capacitors and other controllers switch ON/OFF more frequently and wear more quickly. This HVAC system design flaw will eventually lead to a shorter useful life for the entire system.

Ask your All Cool AC Maintenance technician to complete a J-Load Calculation to properly size the cooling and heating equipment necessary to service your home. Compare the results of the J-Load to your current system. If your system is oversized, make sure to install the properly sized equipment during the next replacement.

The same is true if your system is too small for your home. You will want to evaluate the cost of your utility bills versus the replacement cost. Your energy consumption may be unnecessarily high, and a larger system could reduce your monthly electricity bill by a substantial amount.

Complications of Rushing Your Routine AC Maintenance Appointment

Avoid focusing on speed during repairs. Two things can result from being in a hurry. First, the technician and the homeowner can be more interested in getting the air conditioner running again than to thoroughly diagnosing the problem and completing proper repairs. The inconvenience of doing without air conditioning clouds the real underlying problem.

Second, the cost and inconvenience of follow-up investigation can lead homeowners and AC maintenance technicians to skip steps that uncover the real issues that result in loss of function. Replacing a capacitor might camouflage the real problem—a power surge that damaged both the capacitor and circuit board. It is best to take the time for a complete investigation and analysis to examine any underlying issues.

Allow the All Cool AC Maintenance technician to complete the necessary testing to ensure the problem is fixed the first time.

Houston Humidity and Your HVAC System: Critical Checkpoints for Local AC Maintenance

Understand the impact of local environmental issues. Our area has very high temperatures and very high humidity. Comfort is not the only issue at stake: high relative humidity indoors can lead to damaged finish surfaces (paints and wood finishes), mold and mildew growth, and musty smells throughout the home. All Cool AC Maintenance technicians will pay special attention to cleaning both condenser and evaporator coils, cleaning the drain pan and drain lines. Local high humidity can also lead to corrosion of electrical controls and wiring, especially outdoors.

A Vital Part of Coastal AC Maintenance

The closer that you live to the coast, the more you need to be aware of the corroding effects of salt air on metal parts and components. Salt exposure causes pitting on metal components, including the condenser coil installed outside. While there might not be anything that you can do about this effect, knowing that it exists will help when it comes to repairs.

Repair vs. Replacement: Tracking Your System’s Lifespan Through Routine AC Maintenance

An air conditioner is a mechanical system with a limited useful lifespan. The average system lasts between 15 and 20 years, but in an environment that includes high temperatures, high humidity, plenty of pollen, and the extended use due to Houston’s extended cooling season, consider that your system might be on the lower range of that average. Be very judicious about decisions to repair compared to a complete AC replacement.

How Can Regular AC Maintenance Prevents Costly Compressor Failures

The Ultimate Guide to AC Maintenance: From Clogged Drains to Frozen Coils

In days past, air conditioning was considered a luxury, only available to the well-to-do. Today, central air conditioner systems are essential building systems for every home, apartment, business, and commercial facility. Unfortunately, air conditioners are mechanical systems, and they tend to wear out and need repairs. What repairs can you expect from your air conditioner if you neglect AC maintenance?

An Overheating Condenser Coll. The chief cause of overheating is a gunked-up condenser coil. The walls of the condenser consist of a network of tubes and fins, designed to release heat into the atmosphere. The fan at the center pulls air through the coil to cool it. However, pollen, which is sticky, is followed by other airborne particles, like dust and grass clippings. These particles act as insulation to keep the heat from escaping the tubes.

When the gas cannot escape, the gas inside the tubes does not cool properly. When the gas returns to the compressor motor, the motor overheats and seizes, a catastrophic failure. Replacing the compressor motor is very expensive. It is better to keep the condenser coil clean than replace the compressor motor.

The Evaporator Coil Freezing. Step inside the central air handler cabinet and find another coil, the evaporator coil. This coil works exactly opposite the condenser coil: the same gas is now cold. Warm air from inside the house blows across the cold coils to reduce the temperature inside. If you find that ice has built up around the evaporator coil, it is a problem.

Check the air filter. The warm air from the house contains a lot of humidity. The moisture condenser on the evaporator coil is good. Normally, the condensation drips down and drains away. However, a clogged filter restricts airflow, so the condensation has a chance to freeze in place. Changing the air filter might just solve this problem. If the filter is not clogged, check all the vents in the home. Blocked vents might also restrict airflow.
If air flow does not solve the problem of a frozen evaporator coil, call your air conditioner technician to check the refrigerant pressure. If the pressure is low, the temperature of the gas becomes much colder, and the condensation freezes quickly and just keeps freezing.

As you make repairs, remember that the ice will melt and will need to be collected to prevent a mess.

A Clogged Drain Line. Remember that the condensation in the evaporator chamber should drip from the coil. It does not just fall to the floor; it collects in a drain pan and drains away to a floor drain or other drainage conveyance. If water drops to the floor, but the evaporator coil is not frozen, check the drain pan and drain line.

Trip the circuit breaker marked “AC.”
Remove the bolts for the evaporator chamber cover. With a flashlight, identify the evaporator coil and the drain pan.
If water is overflowing the drain pan, use a wet/dry shop vac and remove the water. Use the vacuum on the drain line opening as well. The problem may be rust debris that has broken away from the drain pan, or it may be the accumulation of mold growth inside the drain line.
Clean the water mess and make sure the pan drains properly.
Reverse the process: replace the cover and restore power to the air conditioner.

Electrical Wear. Electronics seem so stable and unchanging, but looks are deceiving. The electronic controls, switches, and sensors receive damage with every heating or cooling cycle. One of the first control mechanisms to fail is usually the capacitors. (Capacitors are switch/battery combinations, so it is not surprising that they fail early.) Leave the electronics to trained technicians.

Low Refrigerant Pressure. Saving the worst situation for last, losing refrigerant is a big problem. This problem may present itself in several ways, but the main evidence is the loss of cooling. Refrigerant changes, so the refrigerant in your existing system may be discontinued and unavailable. If the air conditioner stops cooling, call our AC maintenance technicians and let them explore the problem and explain options.

Prioritize Your Summer Comfort with Professional AC Maintenance

Don’t wait for a catastrophic compressor failure or a frozen evaporator coil to leave you sweating in the summer heat. By scheduling your routine AC maintenance today, you can catch hidden issues like clogged drain lines and low refrigerant before they turn into costly emergencies. Call the All Cool AC & Heating team of expert technicians at 281-238-9292 right now to schedule your summertime AC maintenance appointment and ensure your home stays cool and comfortable all season long.

The Hidden Summertime Threats to Your Indoor Air Quality

How to Protect Your Indoor Air Quality from Summer Heat and Humidity

Summertime is known for lengthy periods of heat and humidity, and Texans know how to find relief—air conditioning! However, summertime also presents challenges to indoor air quality due to the same heat and humidity. The most obvious challenges come from the outside, but unseen contaminants already reside indoors. Let’s look at serious summertime air quality issues.

3 Reasons Indoor Air Quality Is Affected By Heat and Humidity

1 Concentration Levels of Contaminants

Home ventilation includes air movement into and out of a home space. Air movement reduces the concentration of indoor air contaminants. VOCs are a good example. Manufactured goods, such as carpet, paint, and furniture, give off traces of chemicals, called volatile organic compounds (VOCs) for years after they are purchased and installed. The most familiar VOC is “that new car” smell. VOCs are only a part of the contaminant problem. Food odors, cleaning products, soaps and perfumes, and bathroom smells also contribute to indoor air concerns. Occupants want to keep the cool, dry air inside, but they also keep contaminants inside, increasing their concentration. The concentration of VOCs and other contaminants is reduced by the introduction of outside air.

2 Mold and Mildew Contamination

Pollen is a problem from early spring to late fall, and gets carried indoors, carried on shoes and clothing, or blown in when doors and windows open. However, pollen does not proliferate.

Mold and mildew is a natural part of the environment, disposing of dead organic matter: the smell of mold might be evident right outside the door, eating away at the mulch in the landscaping bed. Mold spores are also carried into the home on shoes and clothing and blow indoors every time the door opens.

Mold and mildew thrive best in cool, moist, dark spaces, and there are plenty of such spaces inside an air-conditioned home; bathrooms, kitchens, and crawlspaces are examples. The most susceptible spot, though, is inside the air handler cabinet in the evaporator chamber. Here it is truly dark, moist, and cool. Mold can grow on the evaporator coil, the drain pan, and inside the drain line. It is vitally important to keep mold spores from reaching this spot and clean it regularly.

3 Air Filter Maintenance

The air conditioner system has a very effective air filter. Even poor-quality air filters remove most airborne particles, including dust, pollen, and mold or mildew spores. Better quality filters increase the percentage of particles removed.

Since filters are effective, the collection of particles soon coats the entire surface of the filter. When the coating becomes thick, it begins to restrict airflow through the filter, and the filter bends under the force of the air blowing through it. A bent filter allows airflow around the filter, introducing spores into the evaporator chamber, which is not good. It is very important to change the air filter regularly; the filter needs to be changed at least once per quarter.

Since summertime presents problems with indoor air quality, a regular air conditioner is very important. During maintenance, a technician will change the air filter, inspect and clean the evaporator chamber, and ensure that the system functions well all cooling season long. If there is a problem, the technician can identify the issue, make appropriate repairs, and hopefully prevent an untimely emergency breakdown.

Common AC Repair Caused by Hurricanes

How to Prepare Your Home and Avoid Costly AC Repair After a Hurricane

Should a hurricane pass through this location, the damage will be widespread, and the extent of the damage will be determined by the intensity of the storm. No one can predict damage precisely, but there are general expectations that can help homeowners prepare. There are also expectations that will help homeowners make AC repair easier. Damage will come because of:

High Winds. A Category One hurricane will have sustained winds of at least 75 miles per hour, while a Category Five hurricane (the most intense hurricane) can sustain winds of 200 miles per hour. Such winds damage structures, trees, and above-ground infrastructure. Windblown debris is extremely dangerous at these speeds.
Heavy Rainfall. Meteorologists recognize that rainfall during hurricanes contributes to their intensity. This is especially true when a hurricane moves slowly or stalls after landfall: Hurricane Harvey stalled over the area, dropping about 60 inches of rain on the Houston metro area in the matter of a few days.
Lightning Strikes. The number of strikes varies tremendously from storm to storm, but the possibility cannot be ignored.

Storm Surge to Flooding: What to Do Before You Need Hurricane AC Repair

How do these storm features damage home heating, ventilation, and air conditioning (HVAC) systems?

Power Surges and Outages. A short power outage is an uncomfortable annoyance, but a power outage that lasts days or weeks can endanger the family’s health and security. A power outage can result from any one or combination of these storm features and can require extensive repairs. To avoid these repairs, consider

High winds can create a surge of electricity 20 to 50 times the normal rate. A lightning strike can produce 1 million volts and completely overwhelm everything electrical. A whole-house surge protector can shield the wiring and appliances from damaging voltage. A surge protector stops the surge at the electrical service panel.
Without a surge protector, a homeowner can trip the main circuit breaker at the service panel, accomplishing the same results. When the dangerous winds and lightning pass, the breaker can be tripped and power restored.
The above solutions protect a home from dangerous power surges. A backup generator can protect the home and family during lengthy power outages. A transfer switch at the electrical service panel monitors power from the power grid. When power ceases, the home is switched off from the grid, and the generator starts automatically; the process takes a few seconds. When power is restored, the generator shuts off, and the home is reconnected to the power grid.

Repairing damage to the wiring system and replacing ruined appliances is expensive and time-consuming. It’s best to avoid the damage by preventing problems before they happen.

Flooding Damage. Developers, engineers, and planners use research from previous storms to prevent the construction of homes in flood-prone areas. Occasionally, homes still experience flash flooding and, in extremely heavy rainfall, some localized flooding. When flooding begins, there is little to be done but wait. Make sure to trip the main breaker before water enters the home to reduce shock and fire risk. Do not turn the power back on until the home has thoroughly dried out and been completely inspected. Flooding can also cause damage to:

Flooring, drywall, insulation, and foundations, and
Building systems, including electrical, plumbing, and HVAC systems

Flood damage gets into every gap between walls and floors, and behind installed appliances. Wet, dirty water will promote mold and mildew: everything will need to be uncovered, dried, and treated before restoration can begin. Water will collect in affected ductwork, so it will need to be replaced to ensure mold does not remain in the ducts.

Condenser Unit Damage. The most vulnerable HVAC component during a hurricane is the condenser unit installed outdoors. The condenser is susceptible to:

Flying debris
Falling debris from overhead trees
Being blown away: they are lighter than you might think
Losing refrigerant as a result of damage, and
Dust and dirt clog the condenser coil

For the best results, the condenser unit should be strapped to the concrete pad to prevent it from being blown away in the storm. Consider purchasing or fabricating a cover for the condenser to protect it from most debris.

Schedule Your Preventive AC Repair Visit Before the Storm Hits

Hurricane season is just around the corner, and the absolute worst time to find out your cooling system is vulnerable is after a major storm hits. By scheduling a preventative AC repair and AC maintenance appointment today, our technicians can securely strap down your outdoor condenser, check your electrical connections, and ensure your system is ready to withstand severe weather. Don’t risk getting left in the sweltering heat—call All Cool AC & Heating at 281-238-9292 now to protect your home and secure your comfort before the storm season arrives.

What are the top HVAC Hurricane Prep steps I need to do to be ready for hurricane season?

HVAC Hurricane Prep: How to Protect Your System from Texas Storms

It is hurricane and severe weather season in South Texas. Things are better now than they used to be, since the National Oceanic and Atmospheric Administration does a good job at predicting hurricanes days in advance, giving residents plenty of time to prepare. Good preparedness plans are also available from a number of area agencies. But what are the necessary HVAC Hurricane Prep steps homeowners should take to protect their system if a storm approaches?

Storm-Proofing Your Comfort: The Art of HVAC Hurricane Prep

You will need to care for your air conditioner during hurricane season. When a hurricane approaches the area, you only have two things to worry about concerning your air conditioner: whether it will make landfall near you or not. If it doesn’t make landfall near you, you’ve got nothing to worry about. If it makes landfall near you, you’ve got three things to worry about: high winds, heavy rainfall, and lightning strikes.

High Winds

If you have a hurricane with high winds, you have two things to worry about

Will the outdoor condenser be damaged by falling or flying objects? As a precaution, make sure to cut limbs or trees near the condenser (or the house, for that matter) that might crush the condenser. It is made primarily of aluminum, so it will not survive a falling limb, much less a tree. Investigate custom covers for your condenser unit to protect it from flying debris. Or consider fabricating a cover from plywood and securing it around the condenser. Make sure not to run the air conditioner with a cover on, since this will cause catastrophic damage to the compressor motor.

Will the outdoor condenser blow away during the storm? Home improvement stores will have strap kits to ensure the condenser does not blow away. The strap is connected securely to the concrete pad, connecting the condenser to the ground.

The condenser unit is very vulnerable during a storm with high winds, so do your best to protect it from flying away and from other flying objects.

Heavy Rain

If you have a hurricane with heavy rain, you have two things to worry about.

Are you in a low-lying area?

Is your home subject to localized flooding?

If either of these situations describes your home, you are aware of the problems presented by torrential rainfall. The most common HVAC Hurricane Prep solution for your air conditioner is to elevate the condenser unit. Now, the air handler cabinet will also be vulnerable if your home is flooded, but that entails far more preparedness measures to protect your entire home. Elevating the condenser can protect it from anticipated flooding events. Condensers can be raised on earthen platforms or attached to the wall of a home. Local building codes can help you determine the best solution for your setting.

Lightning Strikes

If you have a hurricane with significant lightning strikes, you have two HVAC Hurricane Prep issues to worry about.

Lightning strikes can harm home wiring systems and appliances. Lightning does not have to hit your home to cause damage: it can hit the power grid and travel through the electrical service to your home. The entire system and the home electrical service panel have safeguards to prevent major damage, but with electricity, damage happens very quickly. Possible solutions include a whole-house surge protector or tripping the master breaker as the storm arrives.

Lightning strikes and high winds can cause a power outage that lasts minutes, hours, or weeks. A possible solution is a whole-house backup generator to ensure the home wiring system is protected and keep the air conditioner running while the power grid is down for repairs.

Don’t Wait for the Clouds to Gather to Start HVAC Hurricane Prep—Secure Your Comfort Today

When hurricane season arrives in South Texas, the safety of your home and family is your top priority, but your cooling system shouldn’t be an afterthought. Leaving your outdoor unit exposed to high winds, torrential rain, and electrical surges can lead to catastrophic damage and expensive replacements. Proactive HVAC Hurricane Prep is the most effective way to ensure your air conditioner survives the storm and continues to provide comfort when you need it most. From securing condenser straps and clearing hazardous debris to installing critical surge protection, every preventative step you take now saves you from the sweltering heat of a post-storm power restoration.

Can My AC Maintenance Help With My Spring Allergies?

Breathe Easier This Spring: How Regular AC Maintenance Stops Seasonal Allergies

With the arrival of Spring, we can count on warm weather, increasing humidity, and periods with high pollen in the air. For some, pollen is an annoyance—a yellow coating on vehicles and decks. For others, pollen brings itchy eyes, runny noses, congestion, sneezing, and breathing difficulties.

Spring allergy contributors include trees, grass, and, during wet weather, mold
Fall allergens are ragweed, leaf, and soil mold
Most allergens are present year-round, but grow readily when indoor moisture content is high, including mold and mildew spores, and dust mites

Pollen Preparation: Whole House

There are several things that an allergy sufferer can do to lessen the number of allergens within a home.

Monitor the pollen count. Local weather channels (and websites) monitor local pollen counts. If you know your allergen(s), being aware of outdoor conditions can help prepare for the impact on indoor spaces.
Remove shoes upon entering the home. People walk across a pollen-covered driveway and collect pollen along the way. Taking shoes off at the door prevents the spread of pollen throughout the house.
Practice good housekeeping. Dusting, mopping, and vacuuming contaminants off home surfaces removes them permanently.
Keep doors and windows closed. Use the air conditioner to remain healthy and comfortable.

Pollen Preparation: Home Systems

The air conditioner is part of a larger building system. The system is responsible for keeping the air at a comfortable temperature, but it also cleans the air, removes humidity, and moves the air around to keep it fresh. The normal operation of the air conditioner will serve a home’s occupants well, but there are equipment and supplies that enhance the removal of household allergens.

Air Filters. The heating and cooling system has an air filter, located near the base of the air handler cabinet. Air conditioner engineers have rated filters as to the efficiency of removing airborne particles. Consult your air conditioner manual to determine the proper filter rating for your air conditioner. The more efficient the filter is, the more particles are removed. If a family member suffers from allergies, purchase the most efficient filter suitable for your system.
Clean the Ductwork. Ducts allow air to flow throughout the home, but dust tends to collect inside both the supply and return ducts.
Remove Humidity. Mold, mildew, and dust mites require moisture to bloom and multiply. Cooling cycles remove moisture from the air and let it drain away. The air conditioner should go through a 15-to-20-minute cycle 2 or 3 times per hour to keep the relative humidity between 30 and 50%, which is ideal. If the air conditioner does not remove sufficient humidity, consider purchasing a dehumidifier to remove more moisture.
Consider Adding Ultraviolet Light. Ultraviolet light disrupts cell walls. (We commonly experience this when we are sunburned.) Putting concentrated ultraviolet light inside the ductwork will neutralize (kill) pollen, mold, mildew, mites, bacteria, and virus cells, removing their allergen qualities. The inert organisms are more readily collected by the air filter.
Consider A Whole-house Air Purifier. If allergies and asthma are severe in a family member, research the proper size air purifier for your home. An air purifier can remove particles as small as .3 microns and gaseous contaminants, such as smoke or fumes.

Make sure to keep your air conditioner well-maintained. Preventative AC maintenance includes keeping key components clean and working properly. AC maintenance ensures that the entire system functions properly and keeps your home clean and allergen-free.

Fight Pollen with Proactive AC Maintenance from All Cool AC & Heating

Protecting your family from seasonal allergies starts with a system that is primed to filter out irritants and control excess humidity. Scheduling regular AC maintenance is the most effective way to ensure your unit is actually cleaning the air rather than just circulating dust and pollen.

How AC Maintenance and Quick Fixes Save You Cash

The Budget-Friendly Guide to AC Maintenance and Home Cooling

The seasons change so quickly. A few weeks ago, we were complaining about the cold, and now we are preparing for the long cooling season of Spring and Summer. Here are six easy things to do to prepare and save money on your cooling season energy bills.

Make Sure Your AC is Serviced. You’ve heard the phrase, “a well-oiled machine.” Routine AC maintenance ensures that the complex system and hardworking components are cleaned, tested, and ready for everything the heat and humidity are about to throw your way. The condenser unit will be cleaned, the refrigerant will be gauged, the electronics tested, and the thermostat evaluated to make certain the whole system works properly.
Keep the Cool Inside and the Heat Outside. To separate the outside temperature from the inside temperature, builders installed a thermal barrier in every portion of the building’s envelope. These thermal barriers are given a rating, called R-Value. It is a measure of the resistance of heat transfer through a substance, in this case, walls, attics, windows, and doors. Improving insulation in a finished wall is difficult, except during renovation or remodeling. However, attics can often be observed. The insulation in attics should be ten to twelve inches deep, with an R-Value of 30 to 38. Increasing insulation in the attic will reduce the amount of heat that escapes through the ceiling.
Window Care. In comparison to walls and ceilings, windows offer very little resistance to heat transfer. Single-pane windows have an R-Value of 1 or less, while well-insulated windows may have an R-Value of 2-5. Anything done to reduce heat transfer through windows will have an immediate effect on the comfort of the home and the efficiency of the air conditioning system. Consider good drapes or blinds to block sunlight (a source of solar gain), and close them strategically, from 10 am to 7 pm (longer during extreme heat).
Use Appliances Well. Recognize which appliances create a great deal of heat (dishwashers, stoves/ovens, washing machines and dryers, and water heaters) and use them during off-peak hours. Electricity costs more during the heat of the day, so energy savings can be realized by waiting for evening or early morning hours. Reducing the thermostat of the water heater is possible. The heat produced by these appliances is best reserved for evening hours, rather than contributing to the daytime heat. Of course, these changes must be intentionally added to the family’s schedule.
Reverse the Ceiling Fan Direction. Use ceiling fans during the summertime. Moving the air does not change the temperature of the air, but moving air does feel cooler on the skin, so use this to your advantage. Direction also makes a difference. A counterclockwise rotation pulls cool air up to the ceiling and pushes it out to the far reaches of the room, and a clockwise rotation pushes warm air from the ceiling down to the entire room. A black button at the base of the fan will change direction. This small change makes a difference in the comfort of the home, not the temperature.
Program the Thermostat. Most modern thermostats are either programmable or have Smart technology. This means that temperature changes can be scheduled regularly and automatically. A good practice is to raise the temperature (reduce energy costs) overnight, while everyone is asleep, and during the day, while family members are out of the house (schedules vary with each family). A temperature change of 10 degrees for 8 hours can reduce the cost of air conditioning by ten percent.

AC Filters: How to Decide Which is Best for My Home

AC Maintenance in Richmond for Texas Homes

The Ultimate Guide to Filters: Essential AC Maintenance in Richmond for Your Home

The South Texas climate makes us all appreciate air conditioning. While people survived here before AC, survival was tougher, and life was much different. Windows allowed ventilation, but they also opened the home to mosquitoes and other hazardous pests. Screens on windows limited the number of pests that got in, but it was still hot, humid, and muggy. People were always looking for ways to stay cool and dry in the summer heat.

When AC came along, people could close the windows and doors and keep the cool, dry air inside and the hot, humid air outside. However, air conditioning did not solve all the problems alone. Engineers quickly fit AC will air filters. Here is why:

Air must move or it becomes stale and unhealthy.
The closed windows and doors trap contaminants inside, contaminants like dust, pollen, mold spores, etc. Some contaminants enter the home each time a window or door is opened. Some contaminants are created by occupants (both humans and animals). Some contaminants will grow inside in the right environment.
The overall concentration of contaminants will grow without filtering them out of the air.

How Choosing the Right Filter Simplifies Your AC Maintenance in Richmond

Not all filters are the same.

Some filters are made of paper or cloth fibers. Some are made of synthetic fiber materials.
Some filters are made to be replaced, and some are made to be cleaned frequently.
Some filters carry an electrostatic charge and act like a magnet for the tiny particles in the air.

Filters are classified further by the size of the gaps between the fibers. Filters are rated by the Minimum Efficiency Reporting Value (MERV), based on the percentage of particles of a certain size captured by the filter.

If the gaps are too large, the percentage of particles that pass through is greater and is inefficient at cleaning the air.
If the gaps are too small, the airflow is restricted and creates stress on the air conditioner.

Which size, rating, and type filter is right for your system?

The filter size is determined by the opening in the air handler cabinet. It is usually found at the base of the cabinet, at the juncture where the return air vent enters the cabinet. The size of the filter is stamped on the side: replace the filter with a filter of the same size.
Look for a MERV rating on the package of the new filter. Residential heating and air conditioning systems can use filters with a MERV rating of 8-13: the higher the number, the better the efficiency rating. Filters rated above this can restrict airflow in normal systems. MERV 17 to 20 ratings are called High Efficiency Particulate Air (HEPA) filters and are used in health care and laboratory settings. Systems that use HEPA filters have especially strong blower motors to overcome the small gaps in the filter.
The type of filter is usually determined by the equipment already installed. An electrostatic filter will have specialty equipment to power the filter.

Why Filter Checks are Vital for AC Maintenance in Richmond

How often do air filters need to be changed (or cleaned)?

Even normally efficient air filters are very effective at removing airborne particles. Therefore, air filters need to be cleaned or replaced quarterly. The collection of dust and dander will cover the surface, get thicker by the day, and prevent adequate airflow from passing the filter. This means:

Cooling efficiency will be severely reduced
The air conditioning components are forced to work much harder, which can cause damage.

Why are my condenser coils are causing my AC to blow warm air?

Is Your Unit Ready for the Seven-Month Stretch? AC Repair Richmond Essentials

With the arrival of spring, the cooling season is about to begin in earnest. That means for the next seven months or so, the air conditioner will run quietly in the background of our lives. The results are comfortable, safe spaces inside, while the temperature and humidity outside are very uncomfortable.

The key component of the air conditioner that makes air conditioning possible is the outdoor condenser unit. Underneath the metal covers is a large network of aluminum tubes covered in very thin fins. A large fan is housed in the interior and pulls air, lots of air, through the network of tubes. This assembly is designed to dissipate (or collect) heat very quickly. But where does that heat come from?

Cool Conclusions:

Air Conditioning is a Process of Heat Transfer, Not Just “Creating Cold.”
Airflow Obstructions Lead to Costly Repairs.
Ice is a Warning Sign of Refrigerant Loss.

Inside Your Condenser: Understanding Heat Transfer and AC Repair Richmond

Air conditioning works on a heat transfer principle.

The refrigerant is compressed and then suddenly released. The expanding gas gets cold
The blower motor pulls hot air from the house, passing it over a coil of cold tubes (the evaporator coil).
The refrigerant collects heat, making the air cool and the gas inside the tube very hot.
The hot gas moves outside to the condenser coil. The central fan cools the refrigerant and gets it ready to recycle.

The hot air from inside the house is usually humid. The moisture condenses on the cool coils, making the air both cool and dry.

If your air conditioner stops cooling, this heat transfer process is most likely the problem, and the condenser unit is often involved. This process is rather complex, so, as you might imagine, lots can go wrong. Some of the most common problems include:

Debris is collecting around the condenser unit. There should be 18” to 24” in every direction around the condenser. Make sure that shrubs and grass is trimmed, and leaves are cleared away from the unit.
Dirt and pollen are collected on the condenser coils. This sticky substance acts as an insulator, blocking the transfer of heat. If the refrigerant gas does not cool properly in the condenser, it returns to the compressor too hot. If the compressor overheats, this is a very expensive repair.
Normally, the compression of a known amount of refrigerant produces a known temperature. If the refrigerant finds a pinhole to escape through, the pressure of the refrigerant will cause it to leak quickly. The compression of less gas creates lower temperatures, which usually results in the humidity icing on the evaporator coils.

Seeing Ice in Summer? What You Need to Know About AC Repair Richmond

How will you know?

If you observe ice buildup during the cooling season, it indicates a problem with the refrigerant. The ice might develop on the condenser or on the evaporator coil.
You may notice water leaking from the air handler as the ice melts.
The blower motor will blow plenty of air, but the air will be warmer than usual and will eventually become moving room temperature (hot).

Problems two and three could have many causes, but problem one is definitely a result of the loss of refrigerant.

What To Do

If you experience any of these problems, call your All Cool technician. These problems require a diagnosis, and someone certified in the use of refrigerant gases, which are regulated by the US Environmental Protection Agency. All Cool AC & Heating will have you covered.
