How much does furnace repair cost?

Trustworthy Furnace Repair

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 are the Top 5 Signs My Furnace Needs Professional Repair?

Furnace Repair Indicators

The Ultimate Guide to Furnace Repair Indicators

Natural gas is abundant in Texas: twenty-eight percent of the nation’s natural gas supply comes from Texas. With this ready and inexpensive energy source, it is no wonder that 35 percent of Texas residential furnaces are powered by natural gas. The technology that goes into standard furnaces pulls 80-83 percent of energy, while high-efficiency furnaces convert 90-98 percent of energy from natural gas. It is a clean-burning and efficient fuel.

Natural gas furnaces provide a warm, familiar comfort, and they are usually quicker to heat a home than electric heat, even with a lower blower motor speed.

Natural gas furnaces need special care and maintenance to ensure they function well and safe. After all, you are bringing a flammable gas into the home, and the combustion produces exhaust gases that can be deadly. Here are the leading indicators that your natural gas needs furnace repair.

Unusual noises at the beginning of a heating cycle could indicate you need to call for a furnace repair appointment.

  • A pop with a delayed start. Pilot lights were phased out at the beginning of this century. Newer systems have electric ignition systems. If the ignitor component gets covered in soot, it can be slow to respond to the call for ignition. In the meantime, the valve releases a second or two of extra natural gas. When ignition happens, it creates a mini explosion. The pop is not dangerous, but the concussion can damage the brittle cast iron of the burner assembly. A broken burner is dangerous, so do not ignore this malfunction.
  • Expanding air ducts. During the heating season, the sheet metal of air ducts will expand and contract gently during and after a heating cycle. If the noise is more than gentle, it generally indicates a restriction of airflow. That might be caused by a closed vent or a clogged air filter. If it is chronic noise, it may result from an oversized system.
  • Grinding noise. A furnace has very few moving parts, so metal-on-metal grinding can only have one source—the blower motor assembly. Grinding noise might indicate a broken fan, a loose motor mount, or the need for lubrication. This noise is not just annoying; it is the sound of active damage to the system.
  • When an electrical control mechanism is weak and failing, it can give off a loud buzzing noise. This noise will not go away and is a warning of imminent failure and immediate furnace repair.

How to Spot Inefficiencies and Know When You Need Furnace Repair

  • The thermostat is the ON/OFF switch for the furnace (and air conditioner). When the temperature drops below the desired temperature setting, a message is sent from the thermostat to the furnace to begin a heating cycle. When the temperature reaches the desired comfort level, the thermostat senses it and sends a message to end the cycle. If the thermostat malfunctions, the messages are not sent properly. This may indicate a failing battery, or the thermostat may require recalibration. The problem will not go away without a solution, so do not ignore it.
  • Slow or missed heating cycles may also indicate a dirty flame sensor indicator. A furnace system is complex by necessity. When the thermostat calls for heat, the valve opens, releasing gas, and immediately the burner assembly begins producing heat. The blower motor moves the heat (indirectly) into the home, and when the desired temperature is reached, the thermostat ends the heating cycle. The sensors surrounding the burning of natural gas must be precise and efficiently close the gas valve but keep the blower motor running to capture all the available heat. These sensors are susceptible to soot and dirt, and a dirty sensor may result in poor performance.

Don’t Delay Your Essential Furnace Repair

If you’ve noticed unusual popping sounds, grinding noises, or inconsistent heating cycles, your system is trying to tell you something. Ignoring these warning signs doesn’t just lead to higher energy bills—it can compromise the safety of your home and the integrity of your furnace’s most expensive components. Whether it’s a soot-covered ignitor or a failing blower motor, catching these issues early is the key to a warm and worry-free winter. Don’t wait for a total system failure or a safety hazard to develop. Call All Cool AC & Heating today at 281-238-9292 to schedule an appointment with our expert furnace repair technicians and ensure your furnace repair is handled quickly and professionally.

AC Repair Emergency: Your First Steps When the Cooling Stops

AC Repair Emergency

Facing an AC Repair Emergency? What to Do When Your Home Heats Up

Coming home or waking up to an unexpectedly hot house during the summer months can be quite alarming. After the initial shock and distress, it is time to take action. When a cooler head prevails, here are some steps to prepare for restoring air conditioning to your household during an AC repair emergency.

AC Repair Emergency: Quick Checks Before You Call for Help

Do some initial investigation.

  • Is the air conditioner receiving power? If not, first check the electrical service panel and find the circuit breaker marked “Air Conditioner.” If the breaker is tripped, turn it completely off and then on. Wait a few minutes. If a cooling cycle begins, be very observant. If the breaker continues to trip, a serious problem may have developed. If the breaker has not tripped, check the thermostat to make sure all the settings are correct. The indicator should be on COOL, and the temperature setting should be five degrees cooler than the indoor temperature.
  • Is the air conditioner running, but the air is hot and humid? First, check the air filter. A clogged air filter can restrict air flow through the air handler and interfere with the cooling function. Change the air filter and wait for results. If the cooling function returns, make sure to mark your calendar for a filter change every three months.
  • Is the air cool, but not cool enough to bring the home to the desired temperature setting? Are some areas cooler than others? Is the air cool, but the humidity high?
  • Next, look around and take notice of unusual sights, sounds, and smells. The presence of ice or a large water leak is a very important indication to your air conditioner technician. If the system is buzzing, screeching, or bumping, locate the noise, but do not touch anything. Flip the breaker to prevent further damage and wait for professional help. The air coming from the supply vents should be as fresh as the air in the home. If something smells bad or a little off, make a note of what you are observing.

Create a short list of your observations:

  • The condition of the air filter. If you change the filter, but the cooling function does not return, don’t discard the filter yet; the technician may want to observe the filter.
  • Write down the temperature setting and the actual temperature at the thermostat. The indoor temperature might change before the technician arrives.
  • Write down any steps you might have taken, for example, turning the system off, then rebooting like a computer. Record the results.
  • Write down all of the observations you made.

Now it is time to call the AC repair emergency professionals at All Cool AC and Heating. A wise homeowner will have developed a relationship with a local air conditioning company and perhaps have a favorite technician. Such contractor relationships help during times of emergency, and we are motivated to retain loyal customers.

5 Indications You Need AC Repair Katy

AC Repair Katy

Don’t Sweat It! Key Indicators Your Katy AC Need Repair

Some experiences cause us to stop and consider important life choices. Summers in Katy, Texas, when the temperature and the relative humidity are racing to get to 100 first, might just be one of those choice-questioning events. When you start asking the question, “Why here?”, remind yourself of these two bits of encouragement:

  1. The winters are nice.
  2. We have air conditioning!

Remember that air conditioners need maintenance, and occasionally they need repairs. What are some of the key indicators that an air conditioner needs repair?

5 Indications You Need AC Repair Katy

AC Repair Katy Indication 1: AC Not Working

Stating the obvious, when the air conditioner does not run at all, it is a clear sign that something is amiss. Before calling the technician, check the circuit breaker marked AC; if the circuit breaker is tripped, reset the breaker. If the air conditioner returns to normal, some anomaly may have been responsible. If the breaker trips again and will not stay on, a repair is needed.

Another cause for the air conditioner not working might be the thermostat. The thermostat can be found on an inside wall away from the open sunlight. There are several settings on the thermostat that can cause the air conditioner not to work:

  • A battery charge indicator. The thermostat runs on household batteries. If the batteries are low, the thermostat should indicate the problem, and the air conditioner will not work.
  • An ON/OFF function. This should be set to ON
  • A HEAT/COOL function. This should be set to COOL
  • A temperature setting. There are two temperatures indicated on the thermostat. One is the actual temperature indoors, and the other is the air conditioner setting. When the actual temperature rises above the air conditioner setting, it calls for cooling.

Make sure that all thermostat indicators are correct. Fix them before calling for a repair. If this does not solve the problem, call a technician.

AC Repair Katy Indication 2: Warm or Hot Air

The air blowing from the supply vent should be 15 to 20 degrees lower than the air in the home, usually between 55 and 60 degrees. When the air is noticeably warmer or just hot, it may indicate a serious problem. Before you call the technician for a repair, check the air filter. A fully clogged air filter restricts the air flowing across the evaporator coils, reducing the amount of cooling that can happen. Check the air filter and change it if necessary, before calling a technician for repairs.

AC Repair Katy Indication 3: High Relative Humidity

If the temperature is almost right, but the indoor humidity is as high as the outdoor humidity, it may indicate a repair needs to be made. The moisture is removed in the evaporator chamber, so check that air filter for this problem as well. The warm air inside the home must pass over the cool coil of tubes in the evaporator. If a dirty filter prevents or restricts the airflow, this could be the problem. If the filter is new, call a technician for a repair.

AC Repair Katy Indication 4: Sight, Sound, Smell

Air conditioners run in the background noise of a normal household. If you notice something different, do not ignore obvious facts.

  • If water suddenly flows from the air handler closet, it can be one of several problems, but it should result in a call for repair.
  • If the system suddenly begins to make unusual noises, loud buzzing, cranking, or screeching sounds, or loud banging noises, call a repair technician immediately.
  • The air blowing from the supply vents smells different from normal household odors; it usually indicates a problem that needs to be fixed.

AC Repair Katy Indication 5: High Electric Bills

It might take a while to attract attention, but if the electricity bill suddenly spikes, it may indicate a problem with the air conditioner. Do a little research to see if the use of electricity, measured in kWh, spikes year to year during the same month. This indicates a loss in efficiency and signals that a repair needs to be made.

Staying Cool When the Katy Heat Is On

Living in Katy, Texas, means embracing the heat, but it doesn’t mean you have to suffer through it indoors. Your air conditioner is your best friend during those long, hot summers, and recognizing the AC Repair Katy signs of trouble early can save you a lot of discomfort and expense. Whether it’s a complete shutdown, warm air, excessive humidity, strange noises or smells, or a surprisingly high electric bill, your AC often gives you clues when it needs attention.

Don’t ignore these indicators. A little proactive AC Repair Katy troubleshooting and knowing when to call our professional team can ensure your home remains a cool, comfortable sanctuary, even when the temperatures outside are soaring. So, keep an eye—and ear—on your AC, and enjoy your cool retreat!

Is Your AC Sick? 9 Signs You Need AC Repair

Is Your AC Sick? 9 Signs You Need AC Repair

Avoid the Heat: Know When to Call for AC Repair

Is your air conditioner functioning properly? How can you tell whether you need to repair the air conditioner? Here are some common signs that indicate repairs are in order.

1 High Humidity

When the relative humidity indoors matches the outdoor air, it indicates that the air conditioner is not removing moisture properly. Solid surfaces on furniture, flooring, and walls may feel sticky since the finishes are collecting moisture. Skin may also feel sticky, but it may not be from sweat.

2 High Temperature

Since air conditioning removes both humidity and heat from indoor spaces, whenever the indoor temperature rises, it usually indicates that the air conditioning function is failing. (If the temperature is very high, an old system may struggle to keep up without indicating failure.) Observe the thermostat setting and the actual temperature indicated to determine the depth of the problem.

3 Hot Spots

If the main spaces of the home are cool, but upper-story spaces or rooms far from the air handler cabinet are hotter than normal, it indicates the need for AC repair. This is especially true if these hot spots are a new development.

4 Low Airflow

If the amount of cool air flowing from the supply vents has declined substantially in the recent past, this indicates the need for AC repair. This low airflow may result in high humidity, high temperatures, 

and spaces that are not receiving sufficient cool air.

5 Strange Noises

Usually, air conditioner noises are limited to those associated with a blower motor and the gentle movement of air through supply vents. However, when the blower motor or other air conditioner components begin making loud, irritating noises, such as grinding, screeching, or banging noises, it indicates that the blower motor needs to be repaired. If electrical controls emit loud buzzing or rapid clicking noises, it indicates that AC repair is necessary.

6 Obnoxious Smells

The air conditioner should be moving the available air within the home. When the air exiting the supply vents smells unhealthy, it indicates that something is wrong and needs to be repaired. Healthy indoor air is essential to keep a family safe and healthy.

7 Water or Ice

Anytime ice build-up is observed on any part of the air conditioner components, whether indoors or outdoors, it is a serious problem that requires serious repair. Ice on the coils of the outdoor condenser unit is generally easily observed. However, ice build-up indoors may happen behind the walls of the air handler cabinet. What may be observed more quickly is the water leaking from the cabinet as the ice melts. Ice on the components or water leaking from any components (except through the drain lines) indicates the need for AC repair.

8 Long Cooling Cycles

If the air conditioner cooling cycles are exceptionally long or the air conditioner does not turn off, it indicates a serious problem. Of course, cooling cycles during periods of extreme heat might be normal. However, long cooling cycles during normal heat are problematic.

9 High Energy Bills

The price of energy fluctuates a bit, but if the electricity bill continually rises over the cooling season, it bears further investigation. Do a little research to determine whether the energy required for cooling (measured in kWhs) has increased during this month compared to last year or the year prior.

Components that are failing require more energy to accomplish the required tasks. Increased energy use without the addition of other devices generally indicates the need for AC repair.

Keep Cool and Save Money: Call All Cool for AC Repair

These indicators may happen individually, or several of these indicators may happen at once. If you observe these signs, call your AllCool AC and Heating AC repair technician and schedule an appointment.

All Cool AC & Heating HVAC professionals can assist with your HVAC repair and AC maintenance needs. Schedule your service appointment by calling All Cool AC & Heating at 281-238-9292 or contact us via email and let our NATE-certified indoor air quality technicians put their experience to work for you.

6 Tips for Summertime to Reduce AC Repair

Katy AC Repair

Katy AC Repair Tips to Reduce HVAC Repair Costs

As the summer heat intensifies, south Texans depend on air conditioning for every aspect of life: transportation, work, and being at home. We tend to choose when and how long we expose ourselves to the heat and humidity of the great outdoors.

For this reason, it is important to care for the entire home to enhance the safety, health, and comfort air conditioning brings. The following Katy AC repair steps can help cool a home with better results and efficiency.

Katy AC Repair Tip 1: Acknowledge Solar Power

Many homes are built to accentuate natural lighting, brightening certain spaces for aesthetic purposes. However, this natural lighting can increase solar gain and make a home warmer than desired; the light energy entering a home can increase the indoor temperature by as much as 10 degrees on very sunny days.

Blocking the light on the south side of the house from about 9 to 5 can keep a home cooler and require fewer cooling cycles per hour. Early morning and late afternoon light is less intense and should be more enjoyable.

Katy AC Repair Tip 2: Understand Radiant Heat

Heat also travels through solid objects; when the exterior of the home becomes hot, the heat travels through the building material and enters the home. The purpose of insulation is to create a barrier to radiant heat.

A poorly insulated home allows more heat to pass through walls and ceilings than is comfortable. After construction, usually, the only accessible space for insulation is the attic, so make sure your attic is adequately insulated.

Katy AC Repair Tip 3: Recognize the Benefits of Maintenance

Air conditioning systems are quite remarkable. They cool a home, remove humidity, clean the air, and keep the moving air fresh. The whole house can be cooled to a precise temperature setting and maintained day and night, as desired. However, this precise mechanical system must be properly maintained to ensure it functions properly and efficiently.

Without regular maintenance, performance suffers, cooling costs soar, and the components (or the whole system) reach a premature end of useful life. Manufacturers and HVAC technicians recommend scheduling annual preventative maintenance and quarterly air filter replacements.

Katy AC Repair Tip 4: Schedule Temperature Changes

Many thermostats are programmable, but few homeowners take the time to program temperature changes to their advantage. Is the house empty for extended periods? Do family sleep patterns coincide?

These are two lengthy periods in which the temperature setting could be raised by 5 to 8 degrees without affecting comfort. It would, however, affect energy efficiency and cost to the benefit of the family budget. Take a few minutes and read the instruction manual for the thermostat.

Katy AC Repair Tip 5: Inspect the Vents

Vents are strategically placed throughout the home to ensure the indoor air is thoroughly mixed; supply vents are placed low, and return air vents are placed high. During normal household activities, vents can be covered or blocked by drapes, clothing, or furniture. Take time to notice vents regularly to ensure they remain clear for adequate air movement.

Katy AC Repair Tip 6: Use Ceiling Fans Effectively

Ceiling fans generally assist the air conditioning system, helping to mix the air for improved cleaning and cooling. Static air can develop thermal layers, with warm air high and cool air low. A ceiling fan set to turn counterclockwise will pull the air up and push air out to the sides of the space, mixing the air and moving it toward return air vents.

Call the Katy AC Repair Experts

Routine maintenance and preventative tips like we have outlined can help you reduce Katy AC repair costs this summer.

Katy AC Repair or AC Replacement, Which is Right for You?

Air conditioning became common in the 1950s and by 1960, most new homes were built with central AC. With nearly 70 years of available data concerning air conditioner use, the information concerning longevity is pretty accurate. That is, the average lifespan of air conditioners ranges between 15 and 20 years, while regular preventative maintenance and timely AC repair can add years of service—five to ten extra years.

This information might impact your present situation if your AC system is approaching its teenage years. During this time, you can expect repair bills to mount. It can bring up a dilemma—keep repairing it or replace it. Here are some vital pieces of information to help you make this determination.

The Intricacies of Katy AC Repair

It will also seem that repairs are cheaper than replacement; after all, the replacement cost can be quite expensive. However, there are further cost considerations that should put the replacement cost into a balanced perspective.

  • Research repair invoices for your system and pay attention to the accumulation of bills. One repair bill might not be significant, but a high total or an increase in repair costs might give a different story.
  • This research might also reveal the necessity of repairing the same part repeatedly. When this happens, it often indicates a weakness in the system that is not being addressed. That means further repairs should be expected.
  • When both factors are combined, it signals a rising cost that you should be aware of.
  • As the system ages, larger components are threatened by wear and tear. Large components = large cost. It is at this time that repair costs and replacement costs must be closely compared and considered. Replacing expensive parts on a failing system might not be a wise decision.

“Staying the course” might make sense . . . until it doesn’t.

The Reality of Age

As your system ages, other realities affect the bottom line and impact financial decisions.

  • Older systems, with weakened components, will still try very hard to meet the temperature setting called upon with the thermostat. Cooling with weaker parts requires more energy, and more energy costs more money, and this might become apparent. If you are unsure, request the energy bill from the same month for the last two years, and compare the amount of energy for each month. The energy amount is measured in kWh.
  • Older systems may also suffer in performance. It might be evident during a period of extreme heat; a heat wave might leave occupants uncomfortably warm. An older system might also fail to remove adequate humidity, leaving everyone and everything feeling sticky and moist.
  • An older system gives you a glimpse of the future and allows you to plan for a future replacement. Saving money or adjusting the budget will help you prepare for the large purchase that is sure to come. It is a better plan than wishful thinking.

Preparation should include scheduling the eventual replacement and avoiding times of serious schedule pressure by Katy AC Repair technicians.

Examining the Real Cost of HVAC Repair

Examining the Real Cost of HVAC Repair

The Real Cost of HVAC Repair

A new heating, ventilation, and air conditioner (HVAC) system is installed as a state-of-the-art mechanical system, and it is in its best condition ever. The lifespan of HVAC components is about 15 years for air conditioning and 20 years for heater mechanisms.

Between installation and replacement, there is a sliding scale of expected actions and reactions, maintenance, and repairs. Since about 8 billion HVAC systems are currently in use, these expectations are based on lots of maintenance and HVAC repair experience. Let’s look at what normally happens.

The two nemeses of HVAC systems are dirt and use.

  • Airborne particles surround us, both inside and outside of the home. They go everywhere! We have special functions in our lungs to remove these particles, so it stands to reason that the heating, ventilation, and cooling systems will need to handle dust and dirt in the air.
  • The act of turning an electrical device on and off is minutely violent. Very thin wires are minding their own business when suddenly electrons come rushing through and force things to move, heat, and create light. During a heating or cooling season, the system usually cycles on and off four to five times per hour. These minute violences take their toll on electrical parts.

When we catch a whiff of pepper, it causes us to sneeze or cough, but an HVAC system does not have a way to remove dust, dirt, or pollen. For this reason, manufacturers, HVAC Repair contractors, and even the U.S. Environmental Protection Agency tell homeowners they need to complete preventative maintenance inspections annually. Maintenance combats the two nemeses of the HVAC system.

Homeowners should complete the most important maintenance task on the list. The air filter is constantly collecting dust and needs to be changed at least once every three months. However, with or without regular maintenance, dust and use still take their toll on the system. Problems are rather predictable, based on repair records. Over time, the repairs come in rather foreseeable patterns.

Common HVAC Repair Issues

  • Electrical Controls. Contactors and capacitors that are responsible for turning large components, like compressor motors and blower motors, on and off are susceptible to wear. In the useful life of an air conditioner, these parts are often replaced at least once.
  • Large Components. Two major parts are particularly susceptible to dust: blower and compressor motors. When a filter clogs, the amount of air getting pulled through the filter is greatly reduced. That means the blower motor must work harder to push/pull air across the evaporator coil. It is a bit like sailing a ship while dragging an anchor.

The outdoor condenser unit receives the heat from inside the house and MUST disperse it rather quickly. A central fan pulls an incredible amount of air across a network of tubes and fins that give maximum surface space for cooling. However, when dust, leaves, and grass clippings clog the network, the gas inside the tubes stays too hot and causes the compressor to overheat. This is not good at all.

  • Coolant Leaks. The cooling functions when a refrigerant gas is repeatedly compressed and released inside a sealed network. As you might expect, the gas is under significant pressure, so if even an incredibly small hole or crack develops, the gas leaks out. Not good!

Common Heater Repairs

Some electrical controls used for air conditioning also regulate and control the heater/furnace. The information above applies to the heating system as well. Natural gas-powered heaters might also experience the following problems.

  • Flame Sensors. A sensor remains in contact with the flame, and as a result, soot or carbon builds up on the sensor. Other sensors experience expansion and contraction with every ignition.
  • Burners and Heat Exchangers. A byproduct of burning natural gas is water vapor and furnace parts made of iron that are susceptible to rust building up. Rust is corrosion, so the metal is growing thinner as the rust grows thicker. Cleaning the rust away is only a part of maintenance. Ensuring the corrosion hasn’t created leaks is also necessary since leaks allow deadly gases to enter the home.

The good news is that maintenance inhibits dust and use from causing major problems but detects minor problems early. Unfortunately, the system will need to be replaced. The good news is that regular maintenance can extend the useful life of an HVAC system by at least 5 years.

HVAC System Hurricane Preparedness

HVAC System Hurricane Preparedness

HVAC System Hurricane Preparedness

The NOAA Atlantic Hurricane Season outlook predicted between 14 and 21 named storms for this season, 6 to 11 storms developing into hurricanes, and 2 to 5 storms developing into major hurricanes. The 2023 season is living up to the prediction, with 15 named storms, 6 hurricanes, and three major hurricanes so far. Fortunately, the only major storm hurricane to make landfall was Lee. However, there are still two months left in this year’s season.

If you have lived in a hurricane-prone area for many years, you are aware of preparedness plans for various aspects of life. This is a hurricane preparedness plan for HVAC systems in the area.

Pre-season HVAC System Hurricane Preparedness

There are some general and specific preparation steps that you can take any time before the storm arrives, but they should not be attempted during the storm.

  • Trees and tree limbs may endanger a home and the immediate surroundings when hurricane-strength winds arrive. Remove trees and limbs that can damage the structure of the house and remember to protect the outdoor air conditioner condenser unit.
  • Find hurricane straps for the condenser unit, to secure it to the pad beneath it. Strong winds can pick the unit up and make it a dangerous airborne projectile. Consider buying a canvas condenser cover or making one from plywood.
  • Determine in advance whether to invest in a whole-house or portable emergency generator. Such plans take time to install a transfer switch, permanently install the generator, and plan for fuel storage.

Pay Attention

Hurricanes do not sneak up on people on the coast—storms are tracked across the Atlantic and a rather specific landfall is predicted several days ahead in advance. This gives residents several days to make minute plans before the storm arrives.

  • A part of that plan includes determining if and when your family will evacuate for severe hurricanes since evacuation is ill-advised during the storm.
  • Storing food, water, medicine, and emergency supplies is an essential part of preparedness.

Two Days Prior

  • Begin to cool the house down about 2 days before the storm arrives. The air conditioner should be shut off during the storm to avoid damage from power surges, so lower the thermostat by 5 to 10 degrees for comfort during the storm. This will cool the interior and furnishings in addition to the air.
  • If your preparedness plans include covering windows, now is the time to complete this task.

Hours Before

  • A severe storm will include a storm surge to the coastline, sustained winds of more than 100 mph, and torrential rainfall. The danger from lightning-induced power surges is very high, so flip the breaker at the service panel to shut the HVAC system off. If your home is supplied with natural gas, close the gas valve as well in case of structural damage.
  • If you prepared a condenser unit cover, now is the time to install and secure it. Do not run the air conditioner with the condenser covered, as this will lead to catastrophic system failure.
  • Go inside and stay inside until the winds subside. Stay tuned to local news/weather stations as long as possible.

When Calm Returns

After the storm itself, it will make some careful observations of the immediate surroundings. The power may be out for a while, which is why your plan included cooling the house before the storm.

  • Look for downed power lines and structural damage to the home. Remember, the ground will be saturated, so give downed wires a wide berth.
  • Remove the cover and inspect the condenser unit for damage. The materials that compose the condenser walls are thin and fragile. Look for an oily substance and listen for the hiss of escaping gas.

When the power grid is restored and you believe the HVAC system is intact, flip the circuit breaker to restore power to the HVAC system. Lower the temperature of the thermostat settings by a few degrees and determine whether the system is functioning properly.

After a Hurricane: What HVAC Repairs Might Be in Order

On average, a hurricane hits the coast of Texas every six years. Between 50 and 60 thunderstorms pop up in our fair state each year; approximately 1/3 of them become severe thunderstorms.1 Severe weather happens in Texas often enough that it bears staying aware of conditions and preparing for storms as needed.

The portion of your air conditioning system that is most vulnerable during strong storms is the outdoor cabinet, commonly called the condenser unit. The name is an oversimplification because it performs several functions all at once.

Here is a quick update on the condenser unit’s function and how to protect it from needing HVAC Repairs during severe weather.

Performance

While you might consider air conditioning as bringing cool air into your space, technically air conditioning moves heat from air inside your home to the great outdoors. Since the heat needs to move outdoors, an outdoor unit is necessary.

  • Refrigerant gas, commonly called Freon, moves through a closed loop of tubes.
  • A compressor motor puts refrigerant gas under significant pressure—approximately 400 psi. Since the compression makes the gas extremely hot, it is performed outdoors.
  • When the pressure is suddenly released, the gas becomes very cold very quickly. The refrigerant gas readily absorbs the heat and cools the surrounding air in the indoor cabinet.
  • The hot gas now moves outdoors through a network of tubes to be cooled by moving air. If the gas does not cool, compressing it again will cause the system to overheat and damage vital components.

Potential Damage

While the condenser unit is made of sturdy, industrial components, many of the materials are rather thin and vulnerable to damage from the high winds and heavy rains that characterize strong storms. During a strong storm, shutting off power to the AC system is a good idea; power surges can damage the system’s electronics. Before turning on the air conditioner, inspect the condenser unit for damage, looking for:

  • Strong winds or flood waters can pick up the condenser or worse, cause it to be airborne. In some locations, local ordinances may require the condenser to be strapped down to prevent it from being carried away in high winds.
  • Downed lines. Observe the surroundings carefully, watching for downed power lines. Notice the conduit, carrying electricity to the condenser; it cares high voltage, so take note of any damage to the unit’s wiring. If the wiring is damaged, stay away and call a professional technician.
  • Standing water. Thunderstorms can produce flash flooding, but hurricanes produce huge amounts of rain and can result in a pool of water surrounding the condenser unit. Remember that water is a very good conductor of electricity and do not enter the standing water until the power is shut off to the unit.
  • Tubing damage. Observe two copper tubes that connect the condenser to the indoor cabinet. These tubes contain refrigerant gas and might be damaged by flying debris or movement. If damage is observed, do not turn the system on until repairs are made.
  • Oily leak. The coil of tubing that cools refrigerant gas is susceptible to damage from flying debris or movement of the condenser cabinet. Since the gas is under pressure, the system must remain an intact closed loop. A tell-tale sign of gas leakage is a black, oily substance—a component of the gas. If you observe this substance, call a technician before restoring power to the system.
  • Dirt and debris. The wind carries many objects, both small and large, often at very high speeds. Make sure to clear limbs, leaves, and other large objects away from the condenser. The fan is drawing air through the unit and out the top, so make sure to allow two feet of clearance for adequate airflow.

Use a garden hose and gently wash the coil of the condenser unit. When dust and sand become lodged between the fins of the coil, it reduces the necessary airflow. This can lead to overheating of the compressor motor and catastrophic damage to the unit.
