Air Conditioner Blows Hot Air

In the winter, you probably love it when your HVAC system in Granbury blows hot air. But, during the summer, you want just the opposite. If your AC is blowing out hot air, you have a problem. You should call an HVAC maintenance service, but there are also a few other things you can try to fix your air conditioner.

What’s Causing Your Hot Air?

If you’re wondering why your AC air feels so warm, there are a few possibilities you should consider. All of the following could be the cause of an air conditioning to malfunction and blow warm air:

  1. Dirty Filter: One possibility is a dirty air filter. The filter is responsible for taking small particles out of the air and storing them in a network of fibers. However, a filter can only hold so much dirt. At one point or another, the dirt obstructs the flow of air and keeps your system from cooling properly.
    Before you call for emergency HVAC services, you should check your AC filters. Remove them and check for dirt. When a filter is too dirty, you can see the filth on it. Try replacing the filter with a new one and wait for the AC to kick on.
    If you want to prevent your AC from breaking down, replace your filters once a month or once every two to three months. This keeps the air moving and reduces the toll on your HVAC system.
  2. Frozen Coils: Evaporator coils take heat from the air and begin the cooling process. When the process occurs, condensation forms, the moisture could collect on the evaporator coils and freeze.
    Normally, the moisture should go into your drain pain and off of your coils. But there are several issues that could result in the water resting on the coils and freezing. When you have frozen coils, your system can’t transfer heat. This results in warm air instead of the cool refreshing air you want.
    Unfortunately, you can’t fix this issue yourself. If you melt the ice on the coils, you’re only putting a bandaid on the issue. Whatever is causing the coils to freeze over will continue to freeze the condensation. The best thing you can do is check your coils by turning off your AC, opening the access door, and looking at the evaporator coils. If they’re frozen, call a professional.
    All of the following are causes of frozen coils:
    • Poor airflow
    • Damage to the system
    • Refrigerant leaks
  3. Thermostat Errors: t times, user error is the real cause of a broken AC. You might feel warm air coming from your vents if you don’t have the proper thermostat settings.
    Specifically, you could have your blower fan set to the on mode. The fan will always blow air, even when the AC isn’t actively cooling. If you switch the fan to auto, it will only run when the cooling cycles occur.
    You should also ensure that your AC is set to cool mode. If you have your thermostat on heat mode, the AC won’t ever kick on. If your home is cool enough, the heater may kick on instead of the air conditioner. Look at your thermostat and make sure it’s set to a cool setting. If you have a programmable thermostat, make sure it’s set to a suitable temperature when you’re home.
  4. No Electricity: If your HVAC system doesn’t have electricity running to it, there’s no way for it to work. Whether there’s no power to your home or there is interrupted power, your heating and cooling will fail you.
    When there’s no power, your system won’t work at all. But interrupted power can result in your system blowing warm air. First, look at your circuit panel. Check the breakers and flip them on if they are tripped. If there’s an on or off switch near the outdoor unit, check it and switch it on as well.
  5. Refrigerant Leaks: Although your HVAC system’s refrigerant is in a closed loop, things happen to diminish the refrigerant. A leak in the system causes refrigerant to escape, and that affects the cooling ability of your AC. It could be the reason your air blows warm.
    The refrigerant is what allows hot air to be pulled from the air, and cold air to be released into your home. If a system is low on refrigerant, there’s not enough cold air to keep your home a comfortable temperature. The only way you can fix your AC is to have a technical recharge your refrigerant and repair the leak.
    If you have a refrigerant leak, you should call for help immediately. Refrigerant is a toxic substance and could be hazardous to your health and the environment. Signs of refrigerant leaks include frozen coils, hissing sounds, and high electric bills.

What’s Wrong With Your HVAC System?

The longer you wait to call an HVAC technician about your warm air, the more damage that can occur to your system. Even if it starts as a minor issue, the problem can worsen over time. To save money, call for help as soon as possible.

Warm air blowing from your AC is never good. In fact, it’s a sign of serious trouble. Your air conditioner is trying to tell you that it needs attention. Stop sweating it out and have a licensed technician inspect your system.
