Air Conditioning Guide: Common Reasons Your AC Freezes

Monday, September 10th, 2012 at 12:45 pm

Air conditioning has changed our lifestyle a lot in Phoenix. It lets us stay comfortable indoors, while doing anything from working to sleeping. However, there is nothing worse than your Phoenix air conditioner freezing up on a hot day. Many common problems can cause your air conditioner to freeze.

  • Lack of Sufficient Air Flow

If the air filters in your air conditioner get clogged, collapsed or obstructed or you have undersized air ducts, the air flow from the air conditioner will be restricted, causing the system to freeze. Dirt build-up on the evaporator coil and humidity in the air collected on the coil causing ice build-ups can also restrict air flow.

  • Problems in the Refrigerant

Your air conditioner may end up freezing, if the amount of refrigerant in it is not balanced. If there is very little refrigerant in the coil, it will be extremely difficult for it to absorb heat. This can cause the air conditioner to freeze.

Air conditioners use refrigerant to cool the air that circulates through their system. If the refrigerant level becomes very low, the air conditioner will need to work overtime to circulate cool air. This can cause your AC to freeze. If you suspect that your AC has a low level of refrigerant, it is advisable to get the help of a licensed Phoenix AC professional immediately. Refilling the refrigerant can help you fix this problem. However, it is not advisable to attempt to refill your system on your own, as should be handled only by licensed technicians.

  • Outside Temperature

If there is extreme change in the outdoor temperature within a short period of time, there’s a good chance your air conditioner will freeze up. This problem can be prevented, however, by turning off your AC when the outdoor temperature drops significantly.

A frozen air conditioner causes cooling problems. Regardless of the reason that your Phoenix air conditioning system developed this problem, it is worth getting the help of a certified professional to fix it. This not only helps you restore a comfortable environment in your home, but it will also save you a lot of money in energy bills.  For any AC repair in the Phoenix area, give Cool Touch a call!
