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.

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. Our expert technicians will inspect your filters, clean your coils, and verify that your system is running at peak efficiency to keep your home a safe haven. Don’t wait for the sneezing to start—call All Cool AC & Heating today at 281-238-9292 to book your professional AC maintenance and breathe easier all season long. Taking this proactive step now will significantly improve your indoor air quality and provide lasting comfort for everyone in your household.

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.

Don’t Wait for the Heatwave to Schedule Your AC Maintenance

Ensure your home stays a cool sanctuary all summer long by scheduling your professional AC maintenance today. The All Cool AC & Heating expert technicians will clean, test, and tune your system to prevent costly breakdowns and maximize your energy savings.

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.

If you have any questions about the right filter for your air conditioning, call All Cool today.

Stay Cool and Clean with All Cool AC and Heating: High-Efficiency AC Maintenance in Richmond for Texas Homes

Don’t let a clogged filter compromise your home’s comfort or lead to expensive repairs during the peak of the Texas heat. Regular filter changes are just the first step in a comprehensive plan for AC Maintenance in Richmond, ensuring your entire system runs at peak efficiency.

Why is my furnace making loud noises?

Bangs, Clicks, and Screeches: Why Skipping AC Maintenance Leads to Winter Nightmares

Often, a household is a busy place with lots of noise and activity. Our minds do not process all the stimuli that our eyes, ears, noses, and mouths take in during a single day. Even when everything settles and quiets down, there is plenty to hear. These are the background noises of life, different in each home, yet unique enough to make us familiar with our surroundings.

A portion of that ambient sound is the familiar sounds of heating cycles during the winter. Some furnaces are whisper-quiet, and you barely notice the sound. Others are louder or more evident. Sometimes, a furnace will begin making noises that register as unusual and not a part of what is normally heard. Should you be concerned about loud, unusual noises from the furnace? Here is a short list of uncommon furnace noises and their significance and why you need AC maintenance.

The Link Between Noisy Heaters and AC Maintenance

Loud Pops or Bangs

The normal heating cycle involves a rather precise series of events with a singular result.

The thermostat registers that the indoor temperature has fallen below the comfort setting of the family.
It sends an electronic message to the furnace, calling for heat
The signal opens the gas valve, releasing gas from the burner assembly, AND
The signal also triggers the electronic ignition system to ignite the gas coming from the burner assembly.
Another sensor detects gas and shuts the valve if the gas does not ignite, preventing an explosion.
However, if the ignition system delays for an extra second before igniting the gas, the ignition causes a little mini explosion.

That doesn’t sound so bad; however, the delayed ignition releases enough energy that it can damage the ignition system, the burner assembly, and/or the heat exchanger. Any of these damages can cause the furnace to quit functioning. Damage to the heat exchanger can release carbon monoxide and carbon dioxide into the home.

Solution: turn the furnace off and call All Cool AC and Heating for immediate repair. This is a very serious problem.

Persistent Clicking

Gas furnaces are complex electromechanical devices, and various components will emit occasional clicks. The thermostat relay may click audibly at the start and finish of a heating cycle. Various relays and switches click inside and around the air handler cabinet. The electronic ignition will click a few times, creating a spark to ignite the gas. (If you have a gas range, you might be familiar with this clicking in the kitchen.) If this clicking persists after the gas is ignited and/or after the heating cycle has ended, this is a serious issue.

This malfunction of a component will cause it to wear quickly and fail.
Without an electronic ignition, the furnace will malfunction, resulting in chilly temperatures indoors as well as outdoors.

Solution: turn the furnace off and call All Cool AC and Heating for immediate repair or time to schedule an AC maintenance appointment.

Screeching or Grinding Noises

There are very few moving parts in a furnace. If you hear a loud, annoying grinding or screeching noise, it is most likely a problem with the blower motor assembly.

The blower motor powers a rather large fan cage, which draws air from the house, through the furnace, and back into the house.
The motor has bearings. The fan cage is turned by a belt or chain. Friction and wear can cause any or all these parts to fail, resulting in these loud, annoying noises.
This may result in the loss of heat, although that is not a universal result. It may get noisy and continue to move air throughout the home.

Solution: turn the furnace off and call All Cool AC and Heating for an AC maintenance appointment.

Secure Your Home with Routine AC Maintenance

Don’t wait for a noisy breakdown to realize your HVAC system needs professional attention. By scheduling regular AC maintenance, you can catch small mechanical issues and ignition delays before they turn into dangerous winter emergencies. Our expert team at All Cool AC & Heating is ready to inspect your blower motor, sensors, and relays to ensure your home stays quiet and safe all year long. Contact us today to book your preventative AC maintenance tune-up and enjoy the peace of mind that comes with a perfectly functioning system.

Why is my HVAC System Will Short Cycle?

AC Repair: Understanding the Short Cycle

During normal operations, you should hear your furnace complete 2 or 3 heating cycles per hour, with each cycle lasting approximately 10 to 15 minutes. During extremely cold days or if a home is poorly insulated, heating cycles may be slightly more frequent or last a little longer. However, if heating cycles come very quickly and end just as quickly, this is a condition called “short cycle.”

A short cycle happens when the furnace heats the home successfully, reaching the temperature setting indicated by the thermostat. However, the cycle ends before the air has time to mix and circulate, so rooms that are the most distant from the thermostat are still cold. The cold air forces the thermostat to call for another heating cycle, which, again, ends too soon.

4 Hidden Reasons Your Furnace Will Short Cycle

Short cycles indicate one of several underlying problems that need to be addressed. They include:

A Wrong-sized Furnace. Before a furnace is installed, a technician completes a J-Load calculation, measuring the square footage, insulation value, window and door openings, and other factors about the home that affect heating and cooling. The calculation indicates the proper size furnace, measured in BTU output. A system too small will struggle to keep a home warm with “long cycles,” and a system too large will cause “short cycles.” Both cause furnaces (and air conditioners) to run inefficiently and wear out too quickly.

A Dirty Air Filter. The furnace is working to create sufficient warm air to make a home comfortable. But a dirty filter will reduce the airflow needed to move the heat throughout the home. Dust and other airborne particles collect on the surface of the filter until the filter is completely covered. For this reason, an air filter needs to be changed about every three months (more often if needed).

Thermostat Malfunctions. A properly placed thermostat will be installed on an inside wall, and out of direct sunlight. It functions best when placed in a central spot in the home. If the thermostat is improperly placed, it should be moved. Thermostats are battery-powered, so remember to change the battery annually. Occasionally, thermostats experience wear and need to be recalibrated. A malfunctioning thermostat will cause a furnace system to have short cycles.

Malfunctioning System. An aging or worn furnace may experience electrical or mechanical problems that create the conditions for short cycles. A heat pump that loses refrigerant will also lose the ability to collect heat from outdoors: the blower motor will continue to blow, but the heat will be missing from the coil. Wear can also affect sensors and control mechanisms, including capacitors and control boards (small computers).

If your furnace system begins to exhibit any short cycle tendencies, try these tasks in this order.

Purchase a supply of air filters and change the filter. Observe the furnace to determine whether the short cycles have ended. Make sure to change the air filter regularly.
Check the thermostat settings. Ensure that it is on HEAT or EM/AUX HEAT and that the temperature setting is at least 5 degrees lower than the temperature indicated on the thermostat face.
If the settings are correct, turn the thermostat OFF temporarily and change the battery (or batteries). Observe to see whether the short cycling has ended.
Check the vents and registers around the home. Make sure all are uncovered, since covered vents will reduce circulation.
If short cycles continue, call your furnace/air conditioner technician for maintenance and repair.

Stop the Short Cycle Today

If your system is trapped in a persistent short cycle, ignoring the problem can lead to sky-high energy bills and premature equipment failure. These rapid bursts of activity put unnecessary strain on your HVAC components, often indicating a deeper issue like a faulty sensor or an improperly sized unit. Our professional technicians have the tools and experience to diagnose your system and restore perfectly balanced comfort to every room in your home.

What Are the Risks of Delaying the AC Repair Until Spring

Warning Signs: 3 Things That Lead Directly to Expensive AC Repair

The Real Cost of Delaying Your Annual AC Repair and Heating Tune-Up

South Texas usually experiences winters that are mild enough to give us bragging rights over our northern family and friends. However, cold winter temperatures are present enough to compel us to rely upon a good central heating system. Face it, we can choose between natural gas, electricity, or a heat pump system, but we are still depending on the same type of furnace that the rest of the country is using. These systems provide security, comfort, and a healthy indoor environment during extreme temperatures.

That means that we need to look after our very important building system to protect it from the harm that comes from ignoring maintenance. Heating and air conditioning systems require regular AC maintenance in the same way that cars need regular oil changes, tire rotations, and brake inspections.

The heating and air conditioning system is a complex network that combines mechanical, electrical, and chemical reactions to condition indoor air to counter outdoor environmental conditions. The complexity of the system makes regular maintenance important for several reasons.

Comprehensive Guide to HVAC Maintenance: Reduce Bills, Improve Air, Avoid AC Repair

Dirt, dust, and pollen act to clog filters and condenser grids. They tend to coat components, which can affect indoor air quality or impede heat transfer. These contaminants need to be cleaned away.
Moving parts and electrical connections inevitably result in wear. Some wear creates electrical resistance and requires components to use more energy than normal. Some wear causes corrosion and weakness in metal components. Either way, wear cannot be ignored for long. Neither can AC repair.
AC Maintenance often catches stress and weaknesses that affect efficiency and function. Catching these problems early helps to save on energy bills, reduce further stress, and avoid costly and inconvenient breakdowns.
Such care tends to extend the useful life of the system. The average heating and cooling system lasts about 15 to 20 years. Regular AC maintenance can extend that span by about 5 years.

The Role of Preventive Maintenance in Avoiding Major AC Repair

How does one go about properly caring for a heating and cooling system?

First, it is important to select a quality heating and air contractor to service and repair your home’s system. A technician will visit your home repeatedly, accessing several spaces inside and outside of the home. The same person needs to be trained to service and repair your brand, model, and size system. Make a good choice.

Find a good memory prompt. Seasonal changes work. Calendars, either physical or phone versions, will also work. Add prompts for quarterly air filter changes at the same time.

Get to know the essentials about your heating and air conditioning system.

Is your furnace powered by natural gas or electricity? Does it use heat pump technology?
What size is the furnace? What size is the air conditioner?
Are there auxiliary features of your system that you might not be aware of? There might be an immediate bonus to this knowledge!

This information will be very useful when the time comes to replace the system.

Regular maintenance will:

Improve indoor air quality.
Save significant money on the monthly energy bills.
Keep the system functioning as efficiently as possible.
Reduce the cost of AC repair by catching small problems before they become big problems.
Lengthen the serviceable life of the entire system.
Help you be prepared when the time comes for AC replacement.

Don’t Risk Your Comfort: When to Call for AC Repair Before Winter Ends

Ignoring your unit’s needs now can lead to a complete system failure when you need it most, resulting in complex and expensive AC repair later. Don’t risk a winter breakdown or compromise your indoor air quality by skipping essential maintenance. Protect your investment, reduce energy bills, and ensure peak performance year-round. Call All Cool AC & Heating today at 281-238-9292 to schedule your AC maintenance appointment and avoid that emergency AC repair!

How Often Should You Change Your AC Filter?

Stop Stressing Your HVAC: The Dangers of a Clogged AC Filter

Homeownership is a part of the American dream. However, homeownership also includes several regular maintenance tasks, that, if neglected, can result in disagreeable results. Gutters without guards need to be cleaned regularly to prevent clogged downspouts. Battery-powered devices (such as smoke detectors and thermostats) need the batteries replaced to make sure they function properly when called upon. One such simple maintenance task that should not be neglected is changing the air filter on the heating/cooling system.

How Dirty is Indoor Air?

The air inside our home seems so very clean. You do not realize how many airborne particles are floating around inside until the late afternoon light shines through the window and illuminates the dust particles. The sources of most particles are quite simple and unavoidable:

Most indoor dust particles are skin cells from human and animal inhabitants that naturally flake off.
Wind and motion stir up fine dirt particles that find a way indoors.
Pollen follows us indoors or is generated by household plants.
Exhaust from various sources brings both gas and particulate matter also collect indoors. That includes exhaust from outdoor sources (internal combustion engines and industrial activities) and indoor activities (candles and tobacco smoke).

It seems that indoor air is not as clean as it seems. Air filters provide a vital service to ensure our homes are healthy spaces to live.

Why Change the AC Filter?

Air filters are very efficient, removing most airborne particles. Since the entire volume of air passes through an air filter several times per heating or cooling cycle, the airborne particles quickly coat the filter surface. When the collection builds up, the clogged air filter reduces the amount of air that can pass through the filter. Both heating and cooling functions require vast amounts of air movement through the air handler cabinet. Restricting airflow creates tremendous stress on the blower motor and the electrical control mechanisms that direct the comfort cycles. The result of ignoring a clogged filter is similar to driving a car with the emergency brake on.

How Often Should the AC Filter Be Changed?

Each home is unique, and each family is unique.

Some homes are located near pollution sources with exponentially more airborne particles than most homes, like dirt roads or active construction sites.
Some family members have asthma, allergies, or breathing difficulties and need more frequent filter changes.

A very general rule of thumb is to change the filter every three months/four times per year, but your home might require more frequent changes. Purchase adequate filters for a year and schedule prompts on a family calendar or phone app. Use whatever makes sense to you:

The official change of seasons
Birthdays or holidays, or
Any other pneumatic device that will remind you of this important maintenance task.

Katy Texas AC Maintenance Explained

How Often Should AC Maintenance Be Done?

After a lengthy summer, with plenty of hot, humid days and nights, fall is upon us. The temperatures will finally cool off a bit, so for the next few months, the mild temps and drier air will create a mild reprieve for your air conditioning system. The demand for this vital system decreases radically. This is an excellent time to complete some much-deserved preventative AC maintenance for the air conditioner.

A lot is said about AC maintenance. However, the majority of conversations originate from individuals who provide AC maintenance services. Is this conversation self-serving or a public service? Actually, the conversation arises from technicians with decades of experience in the heating and cooling industry, and they know the difference regular AC maintenance makes.

How Routine AC Maintenance Delivers Lower Energy Bills

AC Maintenance measurably improves the efficiency of an air conditioning system; most air conditioners are 5% more efficient annually with regular maintenance.
This efficiency can be measured in a way that really matters—lower energy bills each month.
A well-maintained system keeps indoor air quality measurably cleaner, making the air healthier and the home less dusty.
Regular AC maintenance adds years of serviceability to a system; maintained systems generally last 5 years longer than those without maintenance.

How Often is AC Maintenance Really Necessary? The Honest Answer from the Experts

Each year, for the benefit of customers, air conditioner technicians remind homeowners to maintain their systems, and those who heed the message reap the benefits.

What is involved in maintaining an air conditioner? Regular AC maintenance includes three main tasks—cleaning, inspecting, and testing.

The primary purpose of an air filter is to clean the air, and it cleans the air very efficiently. To ensure the air filter performs well, it needs to be cleaned or replaced at least quarterly. A preventative maintenance visit will include replacing the filter and a reminder to the homeowner to schedule regular replacement every three months.
Two coils facilitate the transfer of heat, the process that we recognize as air conditioning. A major requirement for these coils to function is that they are kept clean, but dirt, dust, pollen, and yard debris threaten to gum up the coils. The outdoor coil, the condenser, can be cleaned with a garden hose. The indoor coil, the evaporator, is found in the air handler closet. It can be cleaned with a spray bottle filled with a cleaning solution. However, damaging either of these coil sets can be detrimental to your HVAC system. Cleaning should be left to the professional to protect your system components.
A visual inspection is made of the entire system. This often catches obvious issues, such as a worn or cracked belt in the blower motor assembly, a loose electrical connection, or other evidence of wear. Drain pan and drain lines are inspected for water build-up or clogs.
Extensive testing will be completed, using specialty tools and training. The refrigerant gas must be maintained within a narrow pressure range to affect cooling. The refrigerant is transported through a network of tubes, flowing inside and outside, and through both coils. The smallest of nicks or flaws will release this gas into the atmosphere. This is not good for the system or the environment.
An air conditioner is controlled by a complex electrical network of sensors and controllers. The current passing through wires may carry as little as 14 volts or as much as 220 volts. Testing takes the proper equipment and training. Finding and replacing a weakened control mechanism can keep a small issue from becoming a major problem.

Spring and Fall: The Best Times You Need to Schedule AC Maintenance

Ultimately, scheduling professional AC maintenance twice a year—ideally in the spring and fall—is the single most effective way to protect your investment, ensuring maximum efficiency and cleaner indoor air. This routine commitment to cleaning, inspection, and testing not only lowers your monthly energy bills but also significantly adds years of reliable service to your air conditioning unit.

What to Do About an AC Refrigerant Leaks

Don’t Ignore an AC Refrigerant Leak: Your System Depends on It

As summer winds down and the cooler weather approaches, the trusty air conditioner continues to perform the tasks of cooling, cleaning, moving, and dehumidifying indoor air. However, if an air conditioner’s performance is declining, it should cause a homeowner to take notice and call for an AC maintenance technician to inspect the system.

Air conditioning systems do not use fuel; they use a manufactured gas, designed to readily transfer heat, deemed a refrigerant or coolant gas. An air conditioner requires a static amount of refrigerant gas to cool the space properly. When the gas pressure decreases, the system tries to continue the cooling process without the proper refrigerant gas. When the air conditioner tries so very hard with inadequate pressure, it will cause crucial components to overheat and fail. This damage is usually very expensive, leading to the replacement of the entire air conditioner system.

AC Refrigerant Leaks? Here’s Why You Need a Pro

What causes a loss of refrigerant pressure? A weakness in the network of tubes that house and transport gas will occasionally result in a minute pinhole, but just enough for the gas to leak away. Since the gas is always under pressure, even a very small hole will release all of the refrigerant gas. Leaks often develop in the weakest portion of the system:

Joints between portions of tubing
The two major coils, where tubes are bent at 900 angles repeatedly

AC Refrigerant Leaks can also occur whenever the system’s tubing is damaged by contact or movement.

AC Refrigerant Leaks can be very difficult to locate and correct.

The leaks are usually very tiny holes, leaking minute amounts of gas. Gas will continue to leak even when the air conditioner is not running, since the gas remains under pressure at all times.
When the gas has completely leaked away, it is nearly impossible to locate the source of the leak. Often, additional refrigerant will need to be added to find the leak, knowing the gas will be leaking away.
The entire system will need to be checked, both indoor and outdoor components. Some of these components are difficult to reach.

Once the leak has been found and sealed, the whole system will be vacuumed completely to remove the air, various gases, and any other substance that made its way into the tube network. The vacuum will remain in place for a given time as a final pressure check; if a leak remains, the vacuum will be broken, allowing air into the system. The whole process will need to be repeated until all of the leaks have been sealed.

Refrigerants are not environmentally friendly, so it is important to find leaks and fix them quickly. Since they pose a threat to the ozone, the US Environmental Protection Agency is continuously seeking better, more friendly refrigerant gases. Over the last few decades, the EPA has changed the acceptable formulas for residential air conditioning systems.

Certain gases have been discontinued and have not been manufactured for several years. The gas for these systems is very scarce, may not be available, and the available gas for these systems is extremely expensive.
Certain gases have been discontinued and are no longer being manufactured, but a supply remains available. Refrigerant for these systems may be available, and the gas will be expensive.
All refrigerant gases are expensive and should not be allowed to escape into the environment if possible.

If your air conditioner is performing poorly, do not delay. Call us for service to test the refrigerant level. It could save your system from failure, save you money in repairs, and help preserve the environment.
