Heat Not Working

Why won’t my heat come on?

Why won’t my heat come on? This is one of the most common questions that we get here at Advent Air Conditioning during the winter season. There are many different reasons why your furnace or heating system may not be working properly this time of year. And though it’s best to have an experienced HVAC technician diagnose and fix your system, it’s also helpful to know what the problem might be before you pick up the phone to call us.

Here are just a few common furnace issues that may be to blame for why your heat won’t turn on:

1. Your HVAC system hasn’t been properly maintained.

One of the biggest issues that we see with heating service calls during the winter is that the homeowner has not been taking the appropriate steps to maintain their heating system. If you didn’t schedule a spring HVAC maintenance visit, then this may be the reason for your heating issues.

A dirty blower motor can lead to equipment failure because when the motor is dirty, the heat exchanger doesn’t get enough moving air, causing it to malfunction. Similarly, dirty air filters will restrict the airflow in your system, amplifying any issues you may have and impacting the quality of your indoor air. This is why it’s so important to keep up with your HVAC maintenance schedule to keep the equipment clean and working properly.

2. Your heat pump’s starting components aren’t working.

If you’re using a heat pump to keep your home warm, and it just isn’t working, you may be experiencing issues with the starting components. There are a number of reasons why these components might fail. But when the starting components malfunction, they prevent your equipment from working properly.

3. The ductwork design or installation was done incorrectly.

Sometimes your heating system equipment isn’t to blame for your heating issues but rather your ductwork. Adequate ductwork design and installation are complex, and if your HVAC contractor or home builder tried to cut corners when sizing or installing your ductwork, then you may find that it’s difficult (or sometimes nearly impossible) to keep your home comfortable.

The solution to this issue is to redesign your ductwork for proper airflow. Though this can be a major undertaking, depending on your personal circumstances, it is often the only way that some homeowners can finally achieve a comfortable home temperature year-round.

4. The thermostat isn’t working.

If your thermostat isn’t working properly, you’ll find that it may be difficult to get your home to a comfortable temperature. If your thermostat doesn’t register the correct temperature then it doesn’t matter how much you crank the heat up – your home just will not get warm. If you think your thermostat may be to blame, it could be a simple fix or you may need to replace the device if it’s older.


Are you experiencing issues with your heating system? Since it could be a range of issues causing your heating troubles, it’s best to call in the professionals to diagnose and fix your system. That way, you can start enjoying a comfortable home climate in no time.

TX HVAC issues

Texas Guide to Common HVAC System Issues

Texas homes can have unique issues that homeowners in other parts of the country never encounter or have to worry about. With high heat exposure and long sunlight hours, the key parts of your home can get damaged or wear out quickly. Our unique wildlife can also cause issues with exterior portions of the home and important appliances.

Since your AC unit is an important part of staying cool when summer hits and temperatures peak, it’s well worth your while to pay attention to the condition of the unit and any issues that might arise. Avoid common HVAC issues that can result in the need for costly repairs by looking out for the symptoms of these problems and getting professional help as soon as you spot them.

Appropriate Sizing Makes a Difference

If you live in a Texas-sized home, it’s important to have an air conditioner that can handle all that square footage. If your AC unit is undersized, it will have to work constantly to keep the area cool. This can cause the unit to wear out faster and increase the cost of your utility bills monthly.

The output of an HVAC unit is measured in British thermal units (BTUs) per hour. One BTU is equal to the amount of energy needed to increase the temperature of one pound of water by one degree. In a large home that measures more than 1500 square feet of living space, an air conditioner that has a capacity of at least 30,000 BTUs is needed to keep the space comfortable.

Wildlife Can Wreak Havoc With The Outdoor Unit

Native wildlife, like snakes, possums, and armadillos can chew on exposed wiring and the outer portions of the compressor, which sits outside the home. This can be the cause of a sudden failure with the cooling system, as the indoor parts of the unit will still work, but no cold air will be able to come through. To try and prevent this from happening, you should keep the grass and bushes around the unit trimmed to discourage wildlife from the area.

Increased Humidity Makes The Unit Seem Ineffective

If you aren’t experiencing any HVAC issues but the inside of your home still feels muggy and warm, the issue may be the humidity content in the air. Cool air with a high moisture content doesn’t feel as refreshing and won’t leave you feeling as comfortable as you’d like.

Using a dehumidifier can help capture some of this moisture and remove it from the air so the home feels cooler. If you live in an area that has high humidity year-round, you may want to consider getting a new HVAC unit that has built-in dehumidifier capabilities to do both jobs at once.

Fall HVAC Repair

3 Signs Your HVAC System Needs Repair Before Fall

Though fall tends to be milder when it comes to temperature, there are still days when homeowners are going to need their HVAC system to stay comfortable. Not to mention, fall is the perfect season to look for issues with your heating and cooling equipment so that you can get the system fixed before you really need to use it in winter. Below, we’ll tell you exactly what you need to look for before calling a professional HVAC technician.

Common Signs Your HVAC System Needs Repair

If you notice that your heating or cooling system isn’t working as well as it used to, you may need a repair. Here are a few of the most common signs that you need an HVAC repair before fall:

  1. You notice cool and hot spots throughout your home.

An HVAC system that working properly should be keeping every area of your home comfortable. If you walk around your home and start to notice that certain rooms or spots in your home aren’t the right temperatures, then your HVAC system may be experiencing serious issues.

Though you may be tempted to just adjust your thermostat to balance out the temperature throughout your home, this is only a temporary fix. Not to mention, it’s a fix that may end up costing you even more in increased energy costs. Issues with uneven cooling or heating could be a number of issues, and the best way to find out is to call a trained HVAC technician.

  1. Your energy bills are increasing.

Issues with your HVAC system will not only cause problems with performance but also efficiency. If you notice that your energy bills are increasing but you haven’t made significant changes to your heating and cooling patterns, then this could be a sign that your system needs repairs.

Depending on the age and condition of your heating and cooling system, you may even need to consider a replacement. HVAC systems generally last about 10 years, depending on the quality of the equipment. The only way to know for sure whether it’s a simple repair or needs total replacement is to call a certified HVAC technician to inspect the unit.

  1. Strange noises or smells are coming from your HVAC system.

Though your HVAC unit will make some noise as it operates, it’s important to pay attention to the kinds of noises it makes. A general engine sound during operation is normal, but a loud clanking or grinding noise may be a sign that something is very wrong. A trained HVAC professional will be able to determine where the noise is coming from and what parts may need repair.

Similarly, a working HVAC system should not be emitting strange smells. If you smell something moldy coming from your heating and cooling equipment, this might be a sign of poor air quality or a water leak. While a burning smell or the smell of gas can indicate other types of serious issues with your heating and cooling equipment. At the first sign of strange smells, call in the experts.

My Air Conditioner Won’t Stop Running – What can I do?

Summer is finally here, which means that you will probably find yourself using your air conditioner more often. If you start to notice that the AC runs continuously or it is constantly cycling on and off, there may be an issue with your HVAC system. Understanding the common problems that can cause your air conditioner can run continuously is the first step to diagnosing and fixing the issues.

Why does my air conditioner keep running?

If your air conditioner is running constantly in order to keep your home comfortable, this can be due to a number of issues with your HVAC unit:

  1. The system’s evaporator coil is dirty.

Did you forget your spring HVAC tune-up? If so, your AC may be running because the evaporator coil is covered in dirt or debris. This impacts the cooling process, making your unit work harder than it should to keep your home comfortable. If you suspect this may be the case, make an appointment for an HVAC system tune-up, and one of our technicians will clean and inspect your system.

  1. Your air filter is clogged.

If you don’t remember the last time that you replaced or cleaned your air filter, this may be the culprit. A clogged or dirty air filter will restrict air flow, which makes it difficult for your system to remove humidity and keep the air cool. This causes your system to continue running in order to make up for it. If you replace your AC filter and are still having issues, be sure to call an AC repair technician as it may be a more serious problem.

  1. Your thermostat is broken.

Another common issue that can cause your AC to run constantly is a broken thermostat. When your thermostat isn’t working properly, the HVAC system doesn’t know when to turn off even if your home is already the right temperature. Use a thermometer to check to make sure that your thermostat reads the correct temperature. If you find that it does not, then you may need to replace your thermostat.

  1. You’ve got leaky air ducts.

Another reason your AC may be running constantly is due to air leaks in your home. If you have an older home with older air ducts, there’s a good chance that there may be areas of your ducts that allow cool air to escape. The more air that escapes, the harder your air conditioning system has to work to keep your space comfortable. Seal any air leaks around your home’s doors and windows and check to make sure your insulation is adequate.
