Every machine needs repair services from time to time. Your heater and air conditioner are no exception.

There are some issues that your Garland, TX heating and air conditioning repair service sees on a regular basis. Here are some of the most frequent problems they see:

Clogged Air Filter

Dirty air filters are one of the biggest reasons that homeowners need heating and air conditioning repair. What makes it even worse is that it is an inexpensive component change that could be completely avoidable with regular maintenance. If you are having problems with the way your HVAC unit, the first place to check is the filter.

When you have an air conditioner or HVAC installed, you should check to see how often the manufacturer suggests you change your filter. It can vary from brand to brand, with some needing to be changed every month.

Some units have a reusable filter that you will need to clean when it gets dirty. Follow the manufacturer’s instructions for cleaning, so you don’t damage the filter. How do you know if it needs to be cleaned? One way is to see if light passes through it. If not, you need a clean filter.

Why is it so important to keep your air filter clean? As dirt, dust, and other particles begin to collect on your air filter, it makes it harder for the air to circulate through it. In the case of your air conditioner, it can cause your unit to freeze up. Your heater will have a harder time working, causing added stress to your unit. Too much stress can lead to some major repair problems for your home.

Broken Thermostat

The thermostat is necessary for your air conditioner and heater to work. It sets the temperature that you choose for your home and keeps it at that temperature. If you are having trouble with your HVAC unit, the second place to check is the thermostat.

You should check to see that your thermostat is turned on and set at the preferred temperature. The inside should be clean and the thermostat should be level and out of direct sunlight. These issues could affect the way your thermostat works.

Refrigerant Leaks

If your air conditioner coolant is leaking, it will not be able to cool your house as efficiently as it usually does. Often, when you have a refrigerant leak, you will notice fluctuations in the coolness of your home.

Unlike a lot of other heating and air conditioning repair issues, where the leak is located can affect the cost of the repair. An annual inspection by an HVAC professional can help you avoid the cost of repair and keep your house at a comfortable temperature.


Does it seem like your air conditioner isn’t really cooling your home? You could have a problem with your compressor.

The compressor in your air conditioner is responsible for sending energy to the coolant, shooting it through the coils for the heat exchange. If your compressor is not working, your air conditioner won’t be able to cool your house.

Your compressor needs a precise amount of coolant to function properly. If you don’t have enough refrigerant, it can cause your compressor to run too hot. Eventually, it will seize up. If you have too much coolant, the coolant will come back to the compressor, causing it to break down.

Condenser Coils

Your air conditioner’s condenser coils face circumstances that other parts don’t simply because of where they are located.

Since they are outside with the compressor, they are at the mercy of the elements. Often, they become dirty, keeping them from working properly.

Your condenser coils should be cleaned at least once a year, to keep problems from building up. But sometimes, even with annual cleaning, dirt can overtake your condenser coils.

If you need professional cleaning for your condenser coils, contact your heating and air conditioning repair service.

Noisy During Operation

A noisy system can be a sign that it’s time for heating and air conditioning repair. It is true that all heaters make some noises during their operation. But if your heater is noisier than it should be when it is running or makes odd squeaking or rattling noises, it could be a mechanical problem. Some sounds could also be because of clogged burners or reduction of air flow.

If you think your heater is making too much noise, you should contact your Garland, TX heating and air conditioning repair specialist for an inspection. The sooner you determine what the problem is, the fewer repair issues you are likely to have.

Faulty Ignition Switch or Pilot Light

Which one of these is causing the problem depends on what energy source your heater uses. If you use gas heat, you have a pilot light. Electric heaters use an ignition switch.

Both parts accomplish basically the same task. The pilot light lets the gas unit provide heat, as the ignition switch does in an electric heater.

If your pilot light or ignition switch is not working, your house won’t get the heat it needs. Check to see that your pilot light is lit in your gas heater. If it is continually going out, you may need to have your heating and air conditioning repair technicians work on it.

Blower That Runs Constantly

The blower on your heater and air conditioner should stop running when the appropriate temperature is reached. If yours is continuously running, there is a problem. Most likely, it is due to a faulty limit switch.

The limit switch should automatically turn off the blower when the room registers the set temperature. If yours is broken or faulty, it will not be able to stop the blower.

This not only burns more energy, constant usage without any breaks can wear your blower out quickly. Even worse, you may need further heating and air conditioning repair services because of the additional stress on the unit.
