Every summer we get multiple calls for a frozen air conditioner in the middle of the summer.  How is it possible that your air conditioner turns into a block of frozen ice?

Listed below are 3 common causes of a frozen air conditioner:

A.)  Insufficient air flow.  Typical causes are clogged filter, blower motor not working, dirty coil, collapsed duct work. Remember to change your air filter at least 4 times a year.

B.)  System low on refrigerant.   If your system is low on refrigerant you have a few options.  You can have sealant installed, dye pack, or a nitrogen test.

C.)  Outdoor temperature (Below 60 degrees).  Always be aware of temperature.  Low temperatures will cause your air conditioner to freeze up.

If you see your air conditioning unit freezing up you should call an expert ASAP.  If the problem isn’t dealt with a timely manner, permanent damage can occur.

You should turn off your air conditioner and let it thaw.  Check the filter and air flow.   If for some reason you want to run the air conditioner below 60 degree a special control can be install on your condenser unit.
