Why is My AC Blowing Warm Air?

There are many reasons why your AC may be blowing hot air. When you call My Plumber Heating, Cooling & Electrical, we can perform a diagnostic assessment to determine the exact cause of the problem. Once we've pinpointed the issue, we can get to work and have your AC repair completed in no time!

If your AC is blowing warm air, you may be dealing with the following:

  • Dirty air filter. If it's been a while since the last time you replaced your AC filter, change it!
  • Refrigerant leak. This is something an AC repair technician needs to diagnose and address.
  • Dirty condenser unit. Your outside unit needs to be periodically cleaned for the AC to work optimally.
  • Wrong thermostat setting. Make sure your thermostat is set to "cool" and the fan is switched to "auto."
  • Leaky air ducts. If your ducts have cracks or other damage, cool air may escape before it has a chance to reach you.

How Often Should I Change My AC Filter?

Air filters aren't just for indoor air quality - your air conditioner relies on a clean air filter for efficient operation. When it is neglected, it can get so dirty and clogged that your AC will have to work harder to produce cool air, which diminishes your comfort and raises your energy bill. It's crucial that you replace your AC filter at least every 60 days. If you have allergy or asthma sufferers in your home, or if you have pets, it is a good idea to change your air filter at least once a month.

Preventative Air Conditioner Maintenance in Manassas

A big part of extending the life of your air conditioner and reducing the number of AC repairs your system will need over the course of its lifetime is maintenance. Regular maintenance allows your AC technician to identify any potential issues early on and correct them before they have a chance to turn into larger issues. During your maintenance appointment, your technician will inspect all aspects of your system and evaluate things like refrigerant levels, thermostat accuracy, electrical connections, and internal mechanical systems. Preventative AC maintenance should be completed at least once per year.
