Why Post-Summer AC Maintenance Matters in Sugar Land?

How Professional AC Maintenance Protects Your Sugar Land Home This Fall

Every summer in Sugar Land is hot and humid, but this year has been one of the hottest and driest on record. We have experienced more than 30 days with temperatures soaring above 100 degrees—tough, but expected.

These extreme conditions force air conditioning systems to run much longer and more frequently to maintain comfortable indoor temperatures and humidity levels. On peak days, it can feel like the unit is running nonstop just to keep up. Over the course of a typical Texas summer, an air conditioner can rack up more than 2,100 hours of continuous operation.

By the time cooler fall temperatures arrive, your air conditioning system has endured months of heavy, continuous use. While Texas winters are relatively mild, you can count on next summer being just as hot and demanding. That makes autumn the ideal time for homeowners to complete essential preventive maintenance and necessary repairs.

Preventive AC Maintenance

Indoor and outdoor air quality in the Sugar Land area is generally good, but air conditioners move massive volumes of air daily. Over time, even tiny amounts of airborne particles accumulate, causing dust buildup that lowers system efficiency.

The total volume of air in your home passes through the filter multiple times every day. While filters capture airborne dust and debris, accumulated buildup quickly restricts airflow and lowers cooling capacity. Filters should be replaced at least once every three months. In the summer months, it might be more efficient to change your filters monthly.
Particles that pass around or through the filter collect on the evaporator coil assembly. Because condensation forms on the cold coils during operation, dust and dander stick to the wet surface. This creates an insulating barrier that hinders heat exchange. While the coil is fairly simple to clean, it is often difficult to access.
The outdoor condenser unit uses a central fan to pull large volumes of air across its cooling fins, dissipating heat from the refrigerant inside. Sticky spring pollen often coats these fins, causing dust and lawn debris to accumulate quickly and block airflow.

Extreme heat and humidity force your air conditioner to work at peak capacity, and airborne debris forces it to work even harder. That makes regular AC Maintenance essential to system longevity.

Testing and Repairs

Heating and air conditioning systems rely on complex electrical and mechanical components. Comprehensive testing during an AC maintenance appointment identifies worn or failing parts under stress, allowing you to replace them before a complete breakdown occurs.

The electrical system relies on sensors to monitor operating conditions, switches and contactors to route power, and capacitors to start and run heavy-duty motors. Heavy summer usage causes steady wear on these components, making routine inspection essential to prevent system failure.
Air conditioning relies on a closed system of copper tubing that circulates refrigerant through a cycle of compression and expansion. Even a pinhole leak allows expensive refrigerant to escape into the atmosphere. During routine AC maintenance, our technicians test system pressure to detect leaks early. Any leaks must be repaired before adding new refrigerant, protecting both your system and the environment.

Transition Checkup

A fall AC maintenance inspection also ensures your system is ready for the upcoming heating season. Whether you have a gas furnace or heat pump, our technicians adapt their safety checks and tune-ups to your specific setup.

Electric heating systems rely on resistance heating elements to warm your home. Because these systems have fewer moving parts, AC maintenance focuses primarily on inspecting connections and identifying electrical wear and tear.
Natural gas is another popular heating option in the Sugar Land area. Annual AC maintenance is essential for gas systems because combustion produces water vapor, carbon dioxide, and dangerous carbon monoxide. Precise air-to-fuel ratios are required to ensure complete burning, while proper venting safely removes exhaust gases and prevents acidic condensation from corroding the heat exchanger and flue.
Heat pumps are becoming a more common choice. This system simply reverses the air conditioning process, bringing heat from the outdoors to the indoors. Of course, this means that the air conditioning components work year-round and are in dire need of AC maintenance.

Schedule Your Fall AC Maintenance in Sugar Land Today

Don’t let a long, hot Texas summer take a toll on your home’s comfort and energy efficiency. Protect your system from unexpected breakdowns and ensure seamless heating this winter by scheduling your professional AC maintenance with our expert local technicians. Call All Cool AC & Heating at 281-238-9292 today to book your comprehensive AC maintenance appointment in Sugar Land, Texas, and keep your home comfortable all year long!

How AC Maintenance Prevents Costly Water Damage in Your Home

From Condensation to Clogs: What Causes AC Water Leaks and How AC Maintenance Can Help?

There are a lot of construction configurations for air conditioning cabinet placement. The three most prominent are a utility space outside of the home (say, a garage or basement), a utility closet indoors, and an attic space. Where the cabinet is located determines the seriousness of a water leak. It can mean the difference between a calm summer and drywall or flooring repair project. The location of your HVAC system will also determine how easy AC maintenance tasks will be to conduct.

A further question is, does a water leak from an air conditioning cabinet signal a major problem with the air conditioning system? Let’s look at where the water comes from, how it is created, what can go wrong to create the leak, and how routine AC maintenance can prevent leaks in the first place.

Where does the water come from?

The air conditioning process does not use water, so water is not leaking from a tank or chamber. South Texas summers are both hot and humid. While the air conditioner is cooling the home, it is also removing humidity from the air. All water coming from an air conditioner is the result of condensation. On an average day, a residential air condition can remove 10 to 20 gallons of water from the home; the water is collected and allowed to drain away. When water leaks from the air conditioner cabinet, it is generally the result of a problem with the drainage equipment.

Understanding the process to understand the problem.

Air conditioning uses a process called heat transfer.

An engineered compound, called a refrigerant, will get hot when compressed and cold when pressure is released. The pressure is released inside of a closed network of tubes called an evaporator coil. The coil is housed in a chamber inside the air conditioner cabinet.
A blower motor pulls hot, moist air from the home and blows it across the cold coils. The refrigerant collects heat from the home (cooling the air) and the moisture condenses on the evaporator coil.
A pan is installed under the evaporator coil to collect the water that has condensed on the coil. Some systems have a second drain pan as an added safety measure to prevent leaks.
The pan is connected to a drain line. The water may drain outdoors, to a floor drain, or it may be pumped from the drain pan to ensure the pan does not overflow.

Plenty of things can go wrong without regular AC maintenance:

On new systems, improper installation might cause the problem. The drain pan(s) must be installed level to prevent them from overflowing. The drain line must also have an adequate slope to let gravity cause the water to drain properly.
The drain pan might rust from exposure to water. If rust flakes away, it can block the drain line or the entrance to the drain line
Algae and mold like to grow in cool, dark, wet spaces, the exact conditions found inside the drain line. A sludge can build up and block the free flow of water.
A leak might also stem from ice that develops on the evaporator coil. Ice develops when the refrigerant pressure is low or an inadequate amount of warm air enters the evaporator chamber, allowing the condensation to freeze and build up.
The loss of refrigerant indicates a leak in the closed network.
Inadequate air flow can be caused by a clogged air filter, a dirty evaporator coil, and/or a weak blower motor.

What should be done?

Check your air filter. That is something that you can do yourself.
Locate the exact place where the water is leaking from.
Depending on the weather conditions, it is usually best to shut the air conditioner off. If the temperature is extreme, it may be best to keep the system on and minimize the damage.
Call All Cool for a professional AC maintenance inspection and repair visit.

Most of the things that go wrong can be detected and corrected during preventative AC maintenance. Be sure to schedule your service before these problems develop.

Is Your System Struggling to Keep Up? Here’s When You Need Professional AC Repair

Fast and Reliable AC Repair: How to Bring Back Your Cool Fast

In the Houston area we experience high temperatures and extreme humidity during the entire cooling season. But those factors are supposed to stay outdoors while the air conditioner keeps the indoor spaces cool and dry. Is your house more humid than normal? If so, let’s look at ways AC repair can improve the situation.

Summers in Katy, TX bring scorching heat and high humidity, putting immense strain on your cooling system. Whether you live near Cinco Ranch or Old Katy, dealing with a broken AC requires fast, local AC repair. Is your house more humid than is normally comfortable? If so, let’s look at ways AC repair can improve the situation.

The National Institutes of Health have set an optimum range of indoor relative humidity between 30% and 50%, although acknowledging that up to 60% is safe. Too little moisture can cause dry, chapped skin and cause wood furniture and flooring to dry and crack. Too much moisture will promote mold and mildew growth, cause painted and finished surfaces to feel sticky and warp. Human skin will also feel moist.

The Ultimate Guide to AC Repair: Costs, Troubleshooting, and Maintenance Tips

Air conditioning systems are designed primarily as cooling devices, but an added benefit is the removal of moisture from indoor spaces as the air cools. Here is how this works:

Cooling results from a process called heat transfer. The inside air is not actually cooled. Instead, the heat inside the home space is removed resulting in a cooler temperature. That might seem to be a technicality, but it will help explain how moisture is removed from the indoor air.
When a refrigerant is compressed and the pressure is suddenly released, the result is rapid cooling. This reaction happens inside a network of coiled tubes. The hot air from the home is blown over the cold tubes. The refrigerant collects the heat and moves it outside, while the moisture condenses on the coil. The moisture is collected and drains away.
Air conditioners are not designed to remove an unlimited amount of moisture: remember, the system is designed for cooling, not moisture control. For the air conditioner to remove the maximum moisture content, the system will need to function at a high level of efficiency.

How Katy’s Climate Impacts Your Air Conditioning System and Their AC Repair Needs

Poor Construction Methods. A poorly insulated home or a ductwork system that leaks will increase the amount of heat and humidity allowed to enter the home. This factor can actually overload the system: The resulting rise in heat and humidity will make a home uncomfortable and unhealthy. Improving these conditions will improve the efficiency of an air conditioning system.
Mechanical problems with the system will also contribute to inefficient air conditioner function. Problems will result from a simple malfunctioning part of the loss of refrigerant from the closed network of tubes. An essential step for protecting the system is regular maintenance; the air filter needs to be changed regularly, and the system checked for wear. This approach prevents small problems from getting larger and more expensive.
The age of an air conditioning system is also a contributing factor. The average useful lifespan of an air conditioner ranges between 15 and 20 years. A well-maintained system tends to last longer than average. Despite great maintenance, the system will lose efficiency with each passing year. If your system is struggling to keep up with the excess moisture, check the age of your system. If your system is approaching the end of usefulness, make plans to replace the system.

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.

Schedule Your Expert AC Maintenance Today to Avoid Future Breakdowns

Don’t let another summer catch you off guard with unexpected cooling costs and repetitive system failures. Taking care of your heating and cooling system now saves you stress, time, and money down the road.

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.

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.

Prioritize Your Indoor Air Quality This Summer

Don’t let trapped contaminants, mold, or clogged filters compromise the health of your home and family this summer. The team at All Cool AC & Heating is ready to help you breathe easier with a comprehensive indoor air quality assessment.

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.

Time for a New HVAC? Planning for HVAC Replacement

Avoid a Breakdown: Plan Your HVAC Replacement

Renovations and updates can be very rewarding and rather fun (or very frustrating, depending on your POV). A new coat of paint, new bathroom fixtures, or a transformed kitchen often adds value to a home while enhancing family enjoyment. The decision-making can be exhilarating, and the results can be quite pleasant.

However, not all home updates inspire creative juices or bring such joy. Most homeowners don’t get very excited about replacing the home’s heating, ventilation, and air conditioning (HVAC) system. Yes, replacing the HVAC system will affect the comfort and health of your family for the next 20 years and will definitely reduce heating and cooling costs, so it’s not uncomfortable. But there is nothing to see and therefore it does not elicit much excitement.

Some other benefits of a new HVAC system include:

Expect a new system to be quieter.
New systems will have variable-speed compressors and blower motors since heating/cooling needs vary when the indoor/outdoor temperature difference is slight or extreme.
New systems can have improved filtration or UV lights in the ductwork to improve indoor air quality.
New systems are usually more environmentally friendly.

Determining When It Is Time for an HVAC Replacement

Deciding the best time to replace your HVAC system will take the pressure off such a large purchase.

You should determine:

The age of your current HVAC system. Experience shows these systems last, on the short side about 15 years and on the long side about 25 years. Knowing the age of your system can help you determine when it needs to be replaced. If uncertain, collect the model/serial number from the manufacturer’s plate and take it to the brand’s website.
If replacement is overdue, replacement plans should get underway. Putting a decision off too long might result in a catastrophic failure and an emergency replacement.
If research reveals the system might have a few more years, adjust the budget now if possible, preparation for a replacement might be in order.

Other HVAC Replacement Factors

Beyond age, several other features of older HVAC systems can be detected as indications of systemic degradation.

Outdated Refrigerant. Air conditioners and heat pumps use refrigerant gas to transfer heat in and out of the home. (Refrigerant is commonly called Freon.) The US Environmental Protection Agency is constantly researching better refrigerant gas to protect the Earth’s ozone layer. Outdated refrigerants are regularly replaced with improved versions. Recently banned refrigerants include R-22, R-404a, and R-410a. If your system uses these gases, it may be impossible. If replacement is an option, the cost of replacement can be prohibited. The serial/model number plate will help a homeowner determine the type of refrigerant used.
Small repairs are not uncommon. However, some components are worn and used constantly. While they can be replaced the cost of equipment and installation rivals the cost of complete replacement. For natural gas furnaces, damage to the burner assembly/heat exchanger combination can be an expensive repair. Replacing the compressor on an air conditioner can also be very expensive. Compare the cost of new equipment with the cost of new components before making a decision.
Poor Performance. If adjusting the temperature setting does not result in a comfortable room temperature, it might indicate a minor repair is needed. Or it might indicate the entire system is extremely worn and needs to be replaced. This condition often results in higher energy use (read “high energy bills) at the same time.

All Cool AC & Heating – The Richmond HVAC Replacement Experts

While home renovations often focus on visible upgrades, replacing an HVAC system is a crucial, though less glamorous, improvement that impacts comfort, health, and energy efficiency. Knowing the age of your system is key, as most last between 15-25 years, and planning for replacement before a complete failure can prevent emergencies. Beyond age, consider factors like outdated refrigerant, costly component repairs, and declining performance when deciding if it’s time for a new HVAC system.
