What’s Causing Your HVAC System to Blow Warm Air?

Having a well-maintained HVAC system is extremely important during the summer, when you most need to keep your home cool and comfortable. But what happens  if there’s something wrong with your unit? What if it’s blowing warm air, for example? In cases such as these, it may be time to call an air conditioning and plumbing services expert to help you out. 

Why are you having this problem in the first place? Here are some potential reasons:

Incorrect Thermostat Setting

Sometimes, the reason your HVAC system is blowing warm air has to do with your thermostat, so that’s the first place you need to check. Make sure your system is set to “cool” and your fan is switched to “auto”. Your temperature setting should be around five degrees below what the room temperature reads on your thermostat. 

Dirty Air Filter

If your thermostat is set properly but your HVAC unit is still blowing warm air, you may need to check your air filter. Air filters have to be changed regularly because neglecting to do so will prevent air from passing through your system efficiently. This means it will take longer to cool your home, which increases the chances that your AC will freeze and completely stop working. If this is already happening to your unit, hire a local expert in HVAC and local plumbing services to resolve the issue as soon as possible.

Low or Leaking Refrigerant

When you have low refrigerant, this means your HVAC unit is losing its ability to cool, which is another possible reason for it to be blowing warm air. This is the point where you’ll need a professional technician to repair the issue. Refrigerant isn’t used up like gas, so if it’s low,  then this is an indication that you have a leak. Only a certified technician can fix the leak and add more refrigerant.
