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. Don’t wait for a breakdown; schedule your next appointment with All Cool AC & Heating today to reap the long-term rewards of a well-maintained system.

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.

Why an All Cool AC & Heating Professional is a Must for an AC Refrigerant Leak

Addressing an AC refrigerant leak quickly is crucial to prevent expensive damage to your system and protect the environment. Because these leaks are difficult to locate and fix, a professional All Cool AC & Heating technician is required to properly seal the leak and recharge the refrigerant. Don’t delay—call for service to save your system from failure and avoid costly repairs.

Your Essential Fall AC Maintenance Checklist

Don’t Wait for a Breakdown: The Case for Fall AC Maintenance

As Summer ends, it brings several very familiar and welcome occasions:

The beginning of the school year: buying school supplies, meeting new teachers, and taking those “first day in a new grade” pictures for the scrapbook.
Friday night lights!!
Saturday College Football.
The promise of cooler temperatures and lower humidity. The summer was great; everyone loves summer. But Fall has its own pleasures, and everyone looks forward to its arrival.

After months of dealing with the extreme heat and humidity of Summer, this is also a great time to give your air conditioner a much-needed AC maintenance visit, a Fall reset.

Why recommend AC maintenance at the tail-end of summer?

The AC components have worked hard all summer long. If there are noticeable weaknesses in the air conditioner’s performance, they will be detected now.
An AC maintenance appointment now will prepare it for the cooling season next year.
If you have a heat pump, these same components will continue to perform through most of the winter heating season as well.

This hard-working system needs regular AC maintenance to function at peak efficiency. Air conditioner repairs and replacements slow down during the Fall months, so the AC maintenance schedule is less congested.

Clean, Check, Change

AC maintenance tasks may vary, but the most common tasks fall under three categories.

Cleaning

The air filter, so important to indoor air quality and air conditioner function, is a good starting place. If it has been a while since you last changed your filter, expect to hear some encouragement to change the filter at least quarterly.

While checking the air filter, if the vents appear to be excessively dusty, our AC maintenance technician may recommend that they be cleaned. (Most air conditioning contractors do not clean vents.)
The outdoor condenser unit needs to be cleaned annually. The condenser walls are composed of a vast network of tubes with very thin fins of aluminum. The tubes and fins are designed to dissipate the heat collected inside into the outdoor environment. A large, central fan pulls copious amounts of air through the network to cool them. Sticky pollen, dust, and yard debris get pulled onto and into the network, making the condenser work much harder than it should. A good cleaning with a garden hose washes this collection away.
A similar network of tubes is found inside the air conditioner cabinet. This network is called the evaporator coil, and it exposes the hot air from the house to the cold of the refrigerant. Since the air is humid and the evaporator coil is cold, the coil stays wet from the condensation that collects on it. Dust that bypasses the filter will collect here as well, making the evaporator coil work harder. The drain pan that collects the condensation and the drain line that carries it away will also be cleaned and flushed.

Checking

The refrigerant pressure level will be checked. A loss in pressure is serious, since it indicates a leak. Loss of refrigerant will bring cooling to a halt and can cause serious damage to expensive components.
Electronic controls and sensors will be checked for performance. Constant use creates wear, and this is normal. Common wear patterns happen, so a technician will know where to look first.
The thermostat will also be checked. Most thermostats are programmable, but many homeowners do not know how to make scheduled temperature changes. A technician will check thermostat settings and answer questions concerning programming temperature changes.
The overall performance of the air conditioning system will also be checked. An air conditioner should provide a minimum temperature change during a cooling cycle. A cooling cycle should achieve the desired temperature change within an acceptable time.

Change

If the cleaning and checking uncover a problem or deficiency, the technician will recommend replacing failing parts before they fail altogether.

Let All Cool Give Your HVAC System the All Clear with Fall AC Maintenance

As summer ends, your AC unit deserves a reset and a professional AC maintenance tune-up to ensure it’s in top condition. This simple AC maintenance call with All Cool AC & Heating can save you from a costly repair down the line and guarantee your comfort for next year.

Ultimate Guide to Essential AC Maintenance

Maximize Your AC’s Lifespan: The Importance of Regular AC Maintenance

The heat and humidity this summer will have your air conditioner running overtime to keep your family comfortable. To give you an idea of how hard it is working, if your thermostat calls for 3 to 4 cooling cycles per hour, your air conditioner will complete between 500 and 700 cooling cycles per week. Since it works this hard each week, and the cooling cycle lasts for 8 months or more, admittedly, it could use some AC maintenance and care.

Essential AC Maintenance Tasks

During an annual AC maintenance visit, our professionally trained technicians will complete some very necessary AC maintenance tasks, including:

Replace the air filter. The air filter seems like a rather simple feature of an air conditioner system, but it serves several important functions. It efficiently collects dust and dander, but the collection eventually clogs the filter and limits airflow, thereby limiting the cooling capacity of the AC. (Expect to hear encouragement to replace the air filter quarterly, like clockwork.)
Other components also need to be cleaned, notably the condenser coils outdoors and the evaporator coils indoors. These coils transport heat via the refrigerant gas, from inside the home to the outdoors. Dust and pollen collect on the tubes and inhibit heat transfer. Cleaning the dust away is essential for maintaining air conditioning function.
Testing and inspection. Various electrical parts are prone to wear, so the technician will use testing equipment to ensure all is well. The refrigerant level will also be tested, since a drop in pressure indicates a leak of the valuable gas.

AC Maintenance Benefits

Completing these tasks will certainly:

Reduce repair costs. The testing and inspection is designed to uncover problems with the complex electronic controls while the problems are small. If left undiscovered, the stress of a small problem spreads to other components. A small, inexpensive repair can quickly grow to a much larger, expensive repair.
Catching small repairs early usually extends the useful life of the air conditioner system, often putting off replacement by 3 to 5 years.
Keeping the system clean and running smoothly improves the energy efficiency of the air conditioner; an air conditioner that works harder requires more energy, costing more money to operate.
Keeping the system clean and running smoothly also improves the indoor air quality inside the home.

AC Maintenance Savings

Regular maintenance will result in long-term savings, since:

AC Maintenance tends to uncover problems early and allows their repairs before trouble spreads. That usually results in a much smaller repair bill.
Since AC maintenance improves efficiency, it usually lowers the monthly electric utility bill.
If maintenance extends the useful life of your system, it allows the air conditioner to function three to five years longer, increasing its value and putting off replacement.

The Power of Proactive AC Maintenance From AllCool AC

Given the constant stress placed on your HVAC unit, neglecting its upkeep is a surefire way to invite costly repairs and premature system failure. Regular AC maintenance is a simple yet powerful way to ensure your air conditioner runs efficiently, extends its lifespan, and saves you money on energy bills and future repairs. By scheduling a professional AC tune-up, you are making a smart investment in the comfort and longevity of your home’s cooling system.

AC Maintenance for Katy Texas Homes

Ensure Comfort All Summer: Katy Texas AC Maintenance Checklist

Spring days, with mild temperatures during the day and cool temperatures during the evening, are in the rear-view mirror. It will be a while before opening windows for long periods of time happens in Katy Texas. Accompanying the hotter temperatures will be higher humidity and high pollen count, so keeping the air conditioner performing well all summer is essential for comfortable summer living. Performance and consistency over the long run depend upon a great preventative AC maintenance plan. Do you have a great AC maintenance plan in place?

Scheduling Professional AC Maintenance

There are plenty of steps a homeowner can take to care for an air conditioner system, but there are some steps that need to be handled by a trained HVAC professional.

Anyone who handles the refrigerant gases used for air conditioning and refrigeration must complete U.S. Environmental Protection Agency training and be certified. That is a lot more work than most homeowners are willing to take on.
The air conditioner’s electronics are complex and must be handled with training and on-the-job training; some wires carry 220V and some carry 24V. It is important to know the difference between the two, since one can give a deadly shock.
Heating and air conditioning are processes. Knowing the processes is essential to knowing how to properly maintain the system.
When repairs need to be completed, it is important to know someone who can diagnose the problem and make the repairs.

Schedule Filter Changes

The entire volume of a home’s air passes the air filter 3 or 5 times per cooling cycle. The purpose of the filter is to remove airborne contaminants, and they do a superb job. Since they are so effective, they need to be changed often.

A dirty, clogged filter restricts the amount of air that can flow through the filter, and the air conditioner function requires a massive amount of airflow. A dirty filter prevents your air conditioner from cooling your home (and your furnace from heating your home).
The air filter is located close to the evaporator chamber, the area where humidity is removed from the home’s air. A dirty filter often results in higher humidity inside the home.
For most homes, changing the air filter every three months is the recommended procedure. If your home has extenuating circumstances that require a more frequent filter change—a dirt road or a nearby construction site—you will be in a position to know and make more frequent changes.
Locate the air filter at the base of the air handler closet, where the ductwork brings air from the home to the cabinet. Air filters are available at most hardware and do-it-yourself home improvement stores.

Clean the Condenser Unit

The outdoor portion of the air conditioner is called a condenser unit, and it also acts like a filter.

The walls of the condenser unit are a network of tubes and fins, containing hot refrigerant gas during cooling cycles. A large fan in the hollow center draws air through the network to cool the gas, but it also draws dirt, sticky pollen, and lawn debris, like grass clippings. The collection hinders the free flow of air through the condenser and needs to be cleaned away.
Before trying to clean the condenser, trip the breaker for the air conditioner. The condenser covers are attached with a few metal screws on each side. After removing the cover, use a garden hose to gently wash away the debris and dirt. Replace the covers and flip the breaker back to the ON position.
Make sure to trim shrubs and tall, ornamental grass at least 2 feet away from the condenser unit.

Spring AC Maintenance Checklist

Essential Spring AC Maintenance Tips

Springtime is an important time for air conditioning system maintenance.

The furnace equipment is now dormant until it is called up in late fall, that is, unless your system uses a heat pump. Heat pumps use the same equipment for heating and cooling.
During the early spring, the temperatures are mild, so air conditioning equipment is relatively idle, an ideal time for air conditioning maintenance.
When the temperatures begin to soar, the calls for repairs and replacement of air conditioning systems rise as well. Springtime is an ideal time for scheduling a maintenance call with your HVAC professional.

In the meantime, here are some maintenance steps you can take on your own.

Change the Air Filter

Pollen is at its highest during the early spring; trees, flowers, flowering trees, and grass are all releasing pollen at the same time. The pollen count is enough to trigger sinus problems with or without allergies. A springtime air filter change can help everyone breathe easier. The filter should be changed at least every three months, more frequently if necessary.

Air filters work tirelessly to clean the air, removing pollen, dust, dander, and more. However, when the trapped particles completely cover the filter, it begins to restrict proper airflow. The very best air conditioning technology cannot function properly without adequate airflow.

Clean the Condenser

The outdoor portion of the air conditioner is called the condenser unit. The walls appear to be solid, but the walls are actually a network of tubes, designed to allow considerable airflow between. A central fan pulls air through the tubes, but it also pulls pollen, dust, and all kinds of debris. Pollen is sticky. It sticks to the tubes and fins, and the pollen tends to collect anything other small particles it encounters.

Cleaning the pollen and debris from the condenser is an easy DIY project. Remove the screws around the cover of the condenser and use a garden hose to gently wash away the collected particles. Wash the tubes until the water flows clear, then replace the covers.

Should the pollen and dust continue to coat the condenser, this makes the air conditioner work MUCH harder and it can lead to some serious repair bills. This is a simple task that can be completed with a few tools and a little bit of time.

Change Batteries

The thermostat is the ON/OFF switch for your air conditioner. It is a very small computer with sensors and switches that control a whole, complicated building system. This small computer is powered by common household batteries, and the batteries need to be changed. Matter of fact, there are several small sensors/switches in the home that run on batteries, including smoke alarms and carbon monoxide detectors. Find a time in the spring and change all of your batteries at once.

Schedule Professional AC Maintenance

These are DIY tasks that can be completed by a homeowner. There are plenty of air conditioner maintenance tasks that need to be completed but cannot be completed by a homeowner. They take special equipment and the training to use it properly. Professional technicians test and clean:

The refrigerant level
Electrical controls and switches, some with high-voltage
Functional performance of the air conditioner

Springtime is an excellent time to schedule AC maintenance.

Don’t Wait for the Heat: Spring is Key for AC Maintenance

Spring HVAC Maintenance Tips

Spring into Comfort: Spring HVAC Maintenance

YeeHaw! Spring is almost here! With the end of winter days away, this is the perfect time to schedule a preventative HVAC maintenance visit for your heating, ventilation, and AIR CONDITIONING (HVAC) system. In a few months, the heat will arrive in earnest and keep technicians busy through the long cooling season. The lull in activity between the heating and cooling seasons is perfect for such tasks.

While the HVAC maintenance technician will complete several tasks that require specialized training and equipment, there are several tasks that diligent homeowners can complete to improve efficiency, longevity, and comfort. Here are a few HVAC maintenance steps that homeowners can take to prepare the system for spring and summer.

Take Care of Vents

A network of pipes (ducts) transports air from the house to the air handler and from the air handler to the house. The pipes are called ducts, and the openings inside the house are called vents.

Anything that covers the vents interferes with the free flow of air. The air conditioner, or furnace, depending on the season, requires sufficient airflow; if clothing, furniture, or drapes cover the vent(s), it impedes the adequate flow of air.
The massive amount of air that moves through the ductwork also carries plenty of airborne particles. Over time, some of these particles are collected by the air filter and some are left behind. It is recommended that the ductwork be cleaned every 3 to 5 years, depending on the local environment.

Keep an HVAC Maintenance Schedule

There are certain things that homeowners need to remember to do regularly. Neglecting these routine tasks can have deleterious consequences. To avoid harm to the HVAC system or the home, there are a few things that deserve a calendar prompt to remind homeowners to complete the tasks. Those tasks would include:

Changing the air filter quarterly. With each heating or cooling cycle, the filter faithfully removes airborne particles on the filter surface. When the collection begins to restrict airflow, it reduces comfort and forces the system to work harder. Use a holiday or a seasonal reminder, use a calendar or a phone prompt, but don’t forget.
Several home devices are powered by simple AA or AAA batteries; the thermostat, carbon monoxide detector, and all the smoke detectors throughout the home are battery-powered. Safety agencies recommend using a major holiday as an annual prompt—Memorial Day or Labor Day, for instance.

Clear the Condenser

During the preventative maintenance visit, the technician should clean the outdoor condenser unit. However, the homeowner should take careful pains to keep the condenser clean.

The condenser is responsible for transferring heat from inside to outside. Should dust, pollen or grass clippings collect on the condenser surface, it will impede the heat transfer. Cleaning it away, perhaps twice annually, will assist the air conditioner (and heat pump). Use a garden hose, no power washer, since the pressure of the power washer can damage the condenser fins.
The mower outlet should always pass away from the condenser for several passes to avoid blowing clippings directly onto the condenser surface.
For best results, the condenser needs two feet in every direction. Be sure to trim shrubs and grass away from the condenser and clean up leaves and debris.

Get Your HVAC Ready for Summer: Essential Spring HVAC Maintenance Tips

By addressing these simple yet crucial HVAC maintenance tasks, homeowners can significantly enhance their system’s efficiency and longevity, ensuring a comfortable and worry-free summer. From clearing vents and adhering to a regular filter replacement schedule to maintaining a clean condenser, these steps contribute to optimal performance and reduced energy consumption. Embracing these preventative measures not only safeguards your investment but also guarantees a cooler, more enjoyable home during the sweltering months ahead.

6 Winter AC Maintenance Katy Tasks

AC Maintenance Katy Tasks to Complete Before Winter

It is still warm, but cold weather is still coming. For the next few months, we can count on some cold nights and the occasional (and inconvenient) Alberta Clipper shaking things up a bit. That means homeowners need to pay attention to the furnace system in preparation.

AC Maintenance Katy Task 1

If you have not scheduled a preventative maintenance visit by your preferred HVAC professional. Preventative maintenance includes accessing and testing electrical components with specialized equipment. Regular PM visits help catch glitches while they are small and avoid many major repairs. These visits should be scheduled in the off-peak seasons—spring or fall.

AC Maintenance Katy Task 2

The most important do-it-yourself maintenance task for homeowners is changing the air filter regularly. (That term often appears in HVAC care.) Air filters collect airborne particles with every cooling and heating cycle, but after a few months, the dust collection threatens to clog the filter. A clogged filter restricts the airflow and forces the whole system to work harder—especially the blower motor.

AC Maintenance Katy Task 3

Make sure to change the batteries in the thermostat annually. This ON/OFF switch has a mini-computer with a very low-voltage system, but it will not work without power. It is programmable, so select the temperature setting and schedule temp changes to meet the family routine.

While you have new batteries, change the batteries in smoke and carbon monoxide detectors as well. They are not directly tied to the furnace but provide important safety alerts in case something goes wrong.

AC Maintenance Katy Task 4

Clean the area around the furnace. If your home has a mechanical closet for the HVAC system, it should not be used as a storage closet. Whether it uses natural gas or electricity, the furnace gets hot enough to ignite paper, wood, and most clothing; most household items that might be stored near a furnace are combustible. Take time to remove items at least 2 feet from the furnace. Remove any cobwebs and sweep the area thoroughly as an extra fire safety measure.

AC Maintenance Katy Task 5

If you have a natural gas furnace, observe the burner assembly, checking for rust or excess soot. Turn the furnace on and observe the flame. The flame should be blue; a yellow flame is unhealthy and needs to be checked by a professional.

If you have a heat pump, make sure the outdoor condenser coil has been cleaned with a garden hose. Rake leaves and lawn debris away from the base of the unit and trim shrubs or decorative grass at least 2” in every direction.

AC Maintenance Katy Task 6

Fall is a good time to check attic insulation and the weather-tight seal around windows and doors. A 1/8” gap along the side of a 24” window is the equivalent of an opening in the wall 1” x 3”. These gaps let in more cold air than you might think, so now is the perfect time to close them up. First, feel for drafts around each window and door. Second, carefully run an incense stick or lit candle around the edges of each window and door. Home improvement stores carry the appropriate caulk to apply to weatherproof the openings.

While the temperatures are mild, stick your head into the attic to examine the insulation quality. A nice carpet of insulation approximately 12” deep should blanket the entire attic. Adding insulation whenever needed can make a home much more comfortable year-round.

AC Maintenance Katy Task 7

If it has been a while since the ducts were cleaned, investigate further and consider cleaning the ductwork. Whenever the air stops moving during a heating or cooling cycle, the heavier-than-air particles begin to sink to every surface including the insides of ducts. After a few years, a thick layer of dust can accumulate. This does not interfere with HVAC operation, but it does contribute to poor indoor air quality.

Prepare Your Home for Winter: Essential AC Maintenance Katy to Prevent Breakdowns and Boost Efficiency

Winter AC maintenance Katy is crucial to ensure your system operates efficiently during the colder months, preventing unexpected breakdowns and costly repairs. Regular maintenance, such as inspecting the furnace, cleaning ducts, and replacing filters, helps improve energy efficiency and indoor air quality. AC maintenance Katy technicians at All Cool AC & Heating will ensure thorough inspections, expert care, and peace of mind that your system is ready to keep you comfortable all season long.

AC Maintenance Tips: How to Keep Your System Efficient

AC Maintenance Sugar Land: Providing Longevity And Increasing Efficiency

Frequently, we run into homeowners who are not familiar with purchasing, installing, and maintaining a building system as complex as the heating, ventilation, and air conditioning (HVAC) system found in most modern homes. That might include:

New homeowners, learning for the first time to look after a home
A homeowner who recently experienced a major repair due to poor maintenance
A homeowner who recently replaced the HVAC and wants to protect the investment

For those folks we offer some simple tips for properly maintaining the HVAC system in your home, using a more familiar cycle of maintenance—auto maintenance.

AC Maintenance Sugar Land is Like an Oil Change

Dirt is the enemy of all things mechanical. In an internal combustion engine vehicle, oil keeps moving parts lubricated, but it also cleans the remnants of combustion–carbon and other chemicals–that can cling to the same moving. After a few months, the oil becomes a soup of good lubrication and collected contaminants. The filter helps some, but it all needs to be changed frequently.

HVAC maintenance includes a change in the air filter and instructions on the need to change the filter often—about every three months for most settings. Maintenance will include cleaning the condenser unit, the outdoor portion most often associated with air conditioning.

Dust, pollen, and grass clippings can completely coat the outside of this network of pipes, potentially causing the compressor to overheat. The technician will also warn you when the ductwork needs to be cleaned.

AC Maintenance Sugar Land is Like Tire Care

A car with flat tires cannot perform the primary function it was designed for—transportation. Vehicle maintenance includes keeping the tires properly inflated and preventing air from leaking out of the tires. HVAC maintenance also includes a touch of attention that resembles tire care.

All air conditioning and some heating functions require a closed loop of pipes that carry a refrigerant gas—one of several potential chemical formulas specially designed to absorb, carry, and release heat. Should this gas find a tiny hole and escape, the air conditioner will cease to cool and the heat pump will cease to heat properly.

Preventative maintenance tests the pressure of the refrigerant gas to ensure the network is properly “inflated” to perform heating and cooling tasks. Even a slight decrease in pressure can indicate a leak which will result in the loss of all the gas.

AC Maintenance Sugar Land is Like Battery Checks

Internal combustion engines require the precise delivery of electric charge in the proper sequence. The whole vehicle is controlled by complex electronics, from headlights to the dashboard, and all the cool gadgets available on current models. Both natural gas and electric HVAC systems have the same dependence on electronics; checking these components is essential for both the efficiency and longevity of the whole system.

The thermostat is the ignition for an HVAC system, the ON/OFF switch. Coincidentally, the thermostat is run on battery power and the batteries need to be changed every so often.
Sensors are in place throughout the system to ensure performance, efficiency, and safety. For instance, when heat is needed, the thermostat signals the burner assembly and the burner assembly ignites to produce heat. When the desired temperature is reached inside the home, the thermostat signals the burner to stop, and it does. However, the heat exchanger has plenty of heat left inside, so a sensor does not shut off the blower motor until the heat exchanger cools off sufficiently.

No part of this building system is unnecessary, and every part needs to be maintained regularly. It is recommended that homeowners schedule a preventative maintenance visit annually.
