How to Fix a Frozen Air Conditioner
Summer’s coming (we promise) and here’s a typical scenario with the average homeowner: They’re at home, minding their own business, enjoying a bowl of popcorn and watching their favorite TV show, when all of a sudden – that distant dreadful sound; drip… drip… drip. They look over to see the household pet licking at a puddle that’s gradually forming on the kitchen floor. Just like that, the mood changes: Anxiety, stress, and that ”oh brother!” feeling. How did the leak start?; water heater, leaky toilet, shower, faucet? No – it’s the air conditioner of all things. This can occur anywhere, from Birmingham to Timbuktu, regardless of weather.
Why Air Conditioners Freeze
The evaporator coil is the component of a central A/C unit that actually freezes. This component of the air conditioner transfers (evaporates) heat from the inside to the outside of your Birmingham area home. There are two primary reasons the evaporator coil may freeze:
-
- The restriction of the system’s airflow
-
- Lack of sufficient refrigerant
Either way, the result is that the air conditioner’s evaporator coil will be unable to properly transfer heat, and consequently ‘overcools’ itself. The impact of this super-cooling is condensation (that’s water formation), and over time ice forms from that condensation as it cools below the freezing point. In short, the A/C just turned into an old-school icebox.
What Might You Do When Your A/C Freezes?
-
- Turn the A/C completely off at the thermostat, and do not just move up the temperature on the thermostat. Just make sure the A/C system is completely OFF.
-
- Check to ensure that the airflow around your system is unrestricted. Replace the furnace or air handler’s filter along with any return air filters. Open all the registers completely and verify that they are not impeded by furniture or drapes.

- Call Norrell Service Experts. The air conditioning system needs to be serviced by a professional that is ACE-certified to ensure there are no refrigerant leaks or damage to the equipment. Simply schedule a Performance Inspection or Repair Diagnostic online, or call to talk to a live person right away.
What Does it Cost to Repair?
This can turn into an expensive repair. When your unit freezes over it can lead to a totaled compressor. Replacing your compressor could easily cost as much as a downpayment on a high efficiency model. In fact, many people are forced to pick between installing a new system and repairing the old one. If you move fast, follow the instructions, and call a ACE-certified technician, you stand a better chance of having a less expensive repair.
Your technician will diagnose the situation and how to avoid the issue from occurring in the future. If a leak was really the cause (and that is rare, but possible), the leak has to be repaired or the unit will probably freeze again.
