Why is my Air Conditioner Frozen? Its 120 degrees outside!!
We get this question quite a bit here at Sharp Air Conditioning & Heating. It’s the middle of summer, the Arizona heat is beating down. And all of the sudden your air conditioning system starts pumping out warm air. After a little bit of inspection, you see ice forming on your air conditioner outside.
You would think that would mean your air conditioning is working GREAT, considering its main function is to blow ICE COLD air into your home. What gives? Not to fear, Sharp Air Conditioning & Heating is hear to solve this mystery.
There are a few common issues that can cause an air conditioner to freeze up even during the hottest parts of the summer.
Problems with HVAC systems refrigeration
If your HVAC system has developed a refrigerant leak, this will cause pressures to drop in the evaporator coils, which allows moisture to freeze and accumulate on the coil.
Temperature outside
If you live in Arizona’s high country or even in Phoenix. When the temperatures start to change, night time temperatures can drop below 60 degrees. Most outdoor condensing units, especially in the valley, do not function very well below 60 degrees. If it gets too cold over night, freeze-ups can occur.
Insufficient Air Flow
The most preventable reason for a freeze-up is restricted air flow. Humidity will build up on the coil, causing ice to build up and shut the system down. Dirty filters are the main culprit of this. But this can also come from any other obstructions such as disconnected or undersized duct work. Other components being broken can also lead to frozen coils.
Now that we have pinpointed the issue, what can you do to fix it? Once you have found ice build-up on your HVAC system, the first thing you should do is turn off the system and allow it to defrost. Once it’s defrosted, check to see if there are any airflow restrictions. Replace any dirty filters or clean any visible dirt or debris. Many times, this will fix the issue with no other problems. Other serious airflow problems or refrigeration leaks will require a trained technician to address the issue.
