Prevent a Frozen Air Conditioner This Summer

Prevent a Frozen Air Conditioner This Summer | Aggressive

A frozen air conditioner is more than just an inconvenience that temporarily leaves leaves you without any cooling capabilities. Running the system with an iced up coil also puts stress on the compressor, and if it breaks down or fails, you can end up facing a costly repair or replacement.

There are some steps you can take to prevent A/C icing before these problems occur.

  • Replace the air filter regularly. A clogged filter can severely restrict critically-important airflow through the HVAC system. When the flow of air across the evaporator slows down it allows ice to accumulate and eventually the coil will freeze. To avoid this, check the air filter monthly and change it at the first sign of dirt buildup.
  • Keep the supply and return registers open and unobstructed. Your HVAC system relies on balanced airflow through the return and supply ducts to keep it operating properly. You can ensure it has optimal airflow by leaving all the supply registers open and keeping the return vents free of any obstructions.
  • Avoid dialing back the thermostat. Turning the thermostat setting down really low doesn’t make the A/C cool your home any faster, but it can cause coil icing. For consistent comfort, invest in a programmable thermostat and set it to automatically adjust the temperature based on your daily schedule.
  • Schedule regular A/C maintenance. A pre-cooling season maintenance visit includes critical tasks like cleaning the coil to remove any built up of dirt and debris, which helps avert heat transfer issues and icing.

What to Do if the A/C Freezes Up

Even if you take all of the above precautions, problems can crop up with the cooling system that cause it to freeze up. If this happens, you’ll need the help of an experienced HVAC professional to diagnose the problem, which may be a faulty thermostat or blower fan, a damaged evaporator coil or a leak somewhere in the refrigerant lines.
