What To Do When Your Air Conditioner Freezes

Posted by
This week’s temperatures are going to climb into the high 90s and brush 100. During the summer, air conditioning is important not only for comfort, but for safety. So, what should you do if your air conditioner freezes up? Chances are that you’ve encountered this at some point as a renter or homeowner. By taking the right steps, you can fix this problem and reclaim your comfort! Thawing your HVAC unit is the first step in correcting this issue. To Defrost Your Air Conditioner:
  • On your thermostat, turn your AC OFF and your fan ON.
  • Inspect your air filter. (When’s the last time it was changed? Is it dirty? If so, purchase a replacement air filter.)
  • Check the area around condensate drain pan for water. (As the evaporator coil thaws, dripping water can miss the pan. If this is the case, line the area with towels.)
  • Allow the system to thaw. (This could take a few hours. Why not head to the movies or out to eat?)
  • If necessary, replace your air filter.
  • Set your thermostat to 78° and switch it to COOL.
If your air conditioner doesn’t blow cool air, call your local HVAC company. Elmer’s One Hour Air offers affordable AC service calls to San Antonio and the surrounding areas. Our technicians will be able to tell you if a more serious problem is causing your air conditioner to freeze up. Reasons Air Conditioners Freeze Up
  • Restricted Airflow – This can be due to many things, ranging from dirty air filters and coils to poorly arranged furniture.
  • Your system is low on refrigerant – Commonly referred to by the brand name Freon, the correct amount of refrigerant is necessary for your AC to operate as it should.
  • Undersized Duct System – Like your air conditioner, your duct system should be sized specifically for your home. Undersized ducts will restrict airflow.
