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.

How often does my heater need a furnace maintenance performed by a technician?

The Homeowner’s Guide to Annual Furnace Maintenance in South Texas

Well, this was another strong winter season. Normal winter temperatures, but with extreme cold that was deep and dramatic. Most Texas families were very thankful to have furnaces to keep their families warm and safe when temperatures dropped rapidly. Heating and air conditioning have become an indispensable part of life in South Texas; it is hard to imagine a home without these features.

However, furnace systems are complex mechanical systems, and like every other mechanical system, they need regular maintenance. Maintenance for automobiles is based on miles driven, but how often should a furnace receive preventative maintenance? Furnace maintenance should be based on climate and extreme temperatures, but generally, your HVAC system needs at least annual furnace maintenance. It is best to schedule furnace maintenance during slow times in the Fall, before heating emergencies tend to happen.

Maximize Your System’s Life: How Furnace Maintenance Adds 5 Years to Your HVAC

The benefits of regular furnace maintenance are quite remarkable.

Furnace maintenance ensures high efficiency. Two aspects of heating and cooling use tend to reduce efficiency: friction and dirt. All Cool AC and Heat furnace technicians know the common mechanical and electrical wear points and where dust and debris tend to collect and prevent the movement of heat. Maintenance uncovers these small problems and fixes them before they become big problems.
Improved efficiency reduces the amount of energy necessary to heat and clean indoor air, thus reducing energy consumption. Reducing energy consumption directly by reducing the energy bill.
Improved efficiency reduces the cost of repairs over the long run. The most expensive repairs are emergency repairs. Scheduling regular maintenance avoids the stress of breakdowns and the inconvenience of difficult repairs. Of course, these difficult repairs generally happen during periods of extreme temperature, making them inconvenient and uncomfortable.
Caring for a central heat system ensures that this important building system lasts as long as possible. The average lifespan for furnaces and air conditioners is about 15 to 20 years. Research shows that regular maintenance can add an additional 5 years to the useful lifespan.

Maintaining heating and cooling equipment should be a partnership between a homeowner and a contractor, like All Cool. Homeowner’s maintenance tasks generally do not require specialized equipment or training and include:

Changing the air filter quarterly
Inspecting and cleaning the space around the interior air handler and the exterior condenser unit.
Keep supply and return vents uncovered for good airflow
Change the thermostat batteries annually

Safety First: The Critical Role of Furnace Maintenance in Preventing Hazards

HVAC Technicians will be responsible for maintenance tasks that require specialized tools and equipment, and include:

Inspecting and testing the ignition system and burner assembly, cleaning soot or rust away. The ignition system has very delicate sensors and must be handled properly. Corrosion or a crack in the burner can have disastrous consequences.
Heat Exchanger inspection and carbon dioxide testing are essential. This component is where exhaust gas containing carbon monoxide and carbon dioxide come in close proximity to inside air supply. Rust and corrosion can allow the two to mix, again, with disastrous consequences.
Heat pump systems use the same refrigerant gas as air conditioners. The gas pressure will be tested to detect a leak in the system.
The variable-speed function of the blower motor will be checked and lubricated as necessary, and the motor assembly will be inspected for wear.
Electrical wiring and connections will be inspected for signs of loose connections. Critical sensors, switches, and control mechanisms will be tested. Emphasis will be given to key stress points.
The thermostat calibration will be checked, and the batteries will be changed.
Heating cycle startup and function will be tested: temperature change should be evident within a given period of time.
And, if any of the tasks homeowners can do are left undone, the All Cool technician will complete these tasks as well.

How much does furnace repair cost?

How Much Does Furnace Repair Cost? A 2026 Price Guide

Finding a trusted furnace contractor partner can be problematic, since there are so many questions and too few answers available without an accompanying sales pitch. Plenty of technicians can complete maintenance and make repairs, but finding a trustworthy person that is affordable can be rather tricky. This makes confident decisions very difficult. On the other hand, a contractor can’t prescribe a cost for labor and parts for a furnace sight-unseen. One measure that can meet the needs for answers for homeowners without tying a technician to an unrealistic expectation is to provide a range of costs for maintenance and repairs.

Furnace Maintenance

Let’s start with the most fundamental task: furnace maintenance. Maintenance plans can begin with a one-time inspection and develop into an annual maintenance plan.

A basic furnace inspection should cost between $100 and $200
A comprehensive maintenance plan should cost between $150 and $300

Please remember that we are including a range for a reason. Each HVAC system is different, requires different maintenance requirements, and exact estimates are only available during the maintenance appointment.

Furnace Repair Labor Cost

The cost of labor can vary greatly, and for good reasons. Some projects are simple, and some projects are very complicated. Some furnaces are free-standing, and others are in very confined spaces. Expect that labor for electric furnaces costs differently than servicing natural gas-powered furnaces.

Labor for projects can range between $100 and $200
Labor costs for repairs on electric furnaces range between $100 and $300
Labor costs for repairs to natural gas furnaces range between $150 and $500
Labor costs for emergency calls—late at night, weekends, or in extreme temperatures—can vary since there are many determining factors.

Again, you will receive a comprehensive quote during your furnace repair appointment with your All Cool Furnace repair technician.

Furnace Repair Costs

The costs for repairs include the cost of labor and the cost of components and supplies. The cost of components varies greatly depending on brand, age of the system, and the availability of parts. The labor cost of repairs varies according to the time needed to make the repair. Therefore, we can give some generalizations about projects and give a range, based on our experience with such projects.

Thermostat repair costs range between $100 and $300, while replacement of a thermostat may cost upwards of $600, depending on the features of the thermostat.
Blower motor repairs range between $200 and $300, while replacement costs range between $500 and $900.
Some components are both expensive to replace and difficult to access; as you might imagine, replacement costs are higher for these projects. For example, replacing a heat exchanger for a natural gas furnace can exceed $1500.

This is a starting point: the exact cost of furnace repair labor and parts will be discussed during your furnace repair appointment.

When Furnace Repair is Not an Option: Furnace Replacement

The cost of replacing a furnace is very complex; it generally requires replacement of the air conditioning system as well. Some of the factors that determine replacement costs include:

The characteristics of the home: square footage, insulation quality, number of doors and windows, orientation of the home, etc. Our furnace installation technicians will offer a J-Load Calculation as a free estimate. The J-Load will determine the size of the furnace and air conditioner.
The type of system is also a factor in cost. Electric furnaces are less expensive and require less labor than natural gas systems.
Both furnaces and air conditioners have efficiency ratings. High-efficiency systems cost more than standard efficiency systems.

Be sure to request a J-Load Calculation from your All Cool Furnace repair technician. The more information you can gather, the more confident you will be in your decision if you need to replace your entire HVAC system.

What happens when I do not get my furnace maintained regularly?

Don’t Skip Your Tune-Up: Why Annual Furnace Maintenance Is Non-Negotiable

How long has it been since your furnace was inspected and cleaned? Do you leave yourself a prompt to remind you to schedule preventative maintenance, or do you just ignore the recommendations from industry professionals? What can you expect from preventative maintenance? What can you expect from ignoring preventative maintenance?

Your heating and cooling system consists of mechanical, electrical, and chemical components rolled together into one major building system. The closest thing to compare it to in our experience is an internal combustion vehicle, which is composed of electrical and chemical parts. We know what happens to a vehicle if maintenance is ignored; we can expect a short life with lots of problems. The same thing happens to a residential heating and cooling system when maintenance is ignored.

Mechanical Components Need Furnace Maintenance

The largest mechanical component in a heating system is the blower motor. The motor turns a massive fan that, 1) pulls all air from the home, through the ducts, into an air handler chamber, and 2) pushes the air back into the home. This happens quickly and often—a couple of heating (or cooling) cycles per hour. These fans are usually driven by a belt or chain; either is subject to wear and damage. That means that the blower motor is called into use more than 20,000 times annually under normal circumstances. It is hard to argue against maintaining such a hard-working motor.
Two smaller motors are also working just as hard in the outdoor condenser unit. One motor turns the condenser fan, and the other is a compressor motor, compressing the refrigerant gas to make the air conditioner and/or heat pump function. The consequences of these motors failing can be air conditioner failure and replacement. Ignoring maintenance can be expensive.

Electrical Components Need Furnace Maintenance

The electrical system that controls the heating and cooling system is quite complex and particularly vulnerable to the buildup of dirt from many sources.

Sensors detect heat in almost every phase of heating and cooling. The thermostat detects indoor temperature, yes, but other sensors detect temperature variations in the air handler chamber and other sections to ensure efficiency and safety.
The air filter is designed to clean the air in a home, but it also protects interior sections of the heating and cooling system from dust, dander, pollen, and other airborne contaminants. Letting this filter clog or fail will make the entire system work harder than necessary, putting stress on the electronics in particular and the whole system in general.
Normal use creates wear on all electrical parts. We are quite familiar with how use affects light bulbs. Even when a bulb does not get bumped or damaged, it still fails. Electrical components wear under normal conditions. A worn part creates stress on surrounding electronics. Maintenance detects these minute stress points, with recommendations for the replacement of minor parts while the problem is still minor. Delaying or ignoring these stresses can lead to larger stresses and more expensive replacements.

Chemical Components Need Furnace Maintenance

Both air conditioners and heat pump systems use manufactured gas that readily transports heat. Collectively, these gases are called refrigerants. A loss of refrigerant pressure will reduce heat pump efficiency and eventually lead to heat pump system failure.
Natural gas or propane furnaces ignite and burn gas in a system that must be carefully maintained to function properly and keep the occupants safe. Water vapor from the combustion will create rust. If rust creates an opening in the burner assembly, heat exchanger, or exhaust pipe, it can leak harmful exhaust gas into the home with disastrous consequences.

Maintaining each of these systems is extremely important for continued efficient furnace function.

Furnace Maintenance: Detailed Explanation of the Process

How Furnace Maintenance Protects Your Home and Health

This is the time of year to complete a routine checkup for a residential furnace; this is a responsible maintenance step for homeowners. Check-ups ensure that the furnace is prepared to function properly and efficiently all winter long. Maintenance often uncovers a weakening part that might create a breakdown. Maintenance is much preferred to experiencing a breakdown at the most inopportune time during a deep cold snap.

Furnace Maintenance might seem like a slight, even unnecessary, task. To fully appreciate the work provided by trained professionals, it might be useful to know what happens and why the maintenance tasks are important. So, what is involved in furnace maintenance?

There are three types of furnaces used in our region:

Natural gas-powered furnaces
Electric furnaces
Heat pumps

All three types of furnaces use some of the same components. Maintenance will inspect, clean, and test these components to enhance performance and efficiency. These parts include:

Electrical controls. Furnaces employ a complex network of sensors, switches, and control devices that detect temperature, turn various components on and off, and set limits for safe functioning. The current that flows through these control mechanisms ranges from 220 volts to 14 volts; needless to say, it is extremely important to know the difference between electrical currents.
The main ON/OFF switch is called the thermostat, that small control device attached to the wall. Thermostats are usually battery-powered, and the checkup will include changing the batteries.
A network of ducts transports the heated, conditioned air throughout the home and brings it back to the furnace for redistribution. A heater maintenance visit will include a general inspection of the visible ductwork to uncover glaring problems.

Gas-Powered Furnace Maintenance

These furnaces create heat by the combustion of natural gas. Natural gas is both flammable and explosive. Combustion produces both carbon dioxide and carbon monoxide. Both gases are lethal when introduced to the indoor air. For these reasons, it is vitally important to check the system for safety as well as efficiency.

The ignition system receives an electronic signal, calling for a heating/burning cycle. Old systems used a pilot light. New systems use an electronic ignition system to light the flame. Dirt and soot can interfere with proper ignition, so it needs to be carefully cleaned.
A burner assembly burns the natural gas in a chamber to collect the heat. Another product of the combustion of natural gas is water vapor. When water vapor contacts cast iron, rust will develop. The burner assembly needs to be inspected and cleaned for both safety and efficiency.
The combustion chamber is a heat exchange chamber that transfers the heat to an outer chamber. Rust is corrosive and can create openings in the heat exchanger and exhaust pipe, allowing exhaust to enter the home with disastrous consequences.

Preventive furnace maintenance of natural gas-powered furnaces is very important.

Electric Furnace Maintenance

These furnaces use electrical resistance to create heat. Current passes through a strong heating element and the element gets red hot—about 1,1000 Fahrenheit. Air is passed over the heating elements and blown into the home. Furnace maintenance includes inspection of the elements and controls.

Heat Pump Maintenance

Heat pump furnaces do not create heat; they simply move heat from outdoors. It is the air conditioner in reverse. Instead of moving heat inside the house to the outside, it moves heat from outside the house inside. This will only work efficiently until the outside air drops below 350, when it becomes harder to collect heat from outdoor air. Heat pumps use a heating element system as a backup. Maintenance for a heat pump includes:

Testing the refrigerant gas that makes heat transfer possible.
Cleaning and inspecting the outdoor condenser coil
Cleaning and inspecting the indoor evaporator coil

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.

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.

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.

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.
