How to Fix a Frozen Air Conditioner
Summer’s coming (believe it or not) and here’s a typical scenario with the average homeowner: They’re sitting in their house, minding their own business, happily indulging a bowl of popcorn and watching a movie, when all of a sudden – that distant terrible sound; drip… drip… drip. They look over to see the dog licking at a puddle that’s gradually forming on the kitchen floor. Just like that, the mood changes: Concern, stress, and that sinking feeling. Where did the leak come from?; water heater, leaky toilet, shower, faucet? Not necessarily – the central air conditioner is frozen solid. This can happen anywhere, from Columbus to Thailand, regardless of weather.
Why Air Conditioners Freeze
The part of the air conditioner that actually freezes is known as the evaporator coil. This component of the air conditioner transfers (evaporates) heat from the inside to the outside of your Columbus area home. Usually there are two factors why the evaporator coil may freeze:
-
- The restriction of the system’s airflow
-
- Low refrigerant
Either way, the ending effect is that the air conditioner’s evaporator coil cannot operate to properly dissipate heat, and in essence ‘overcools’ itself. The net effect of this super-cooling is condensation (that’s water formation), and finally ice forms from that condensation as it cools below the freezing point. Yep, the A/C transformed into an old-school icebox.
What Should 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. It is important that the A/C system is completely OFF.
-
- Confirm that there is nothing restricting the airflow to the system. Replace the furnace or air handler’s filter along with any return air filters. Open all the registers completely and ensure that they are not impeded by furniture or drapery.

- Call Stevenson 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 become an expensive repair. When your air conditioner ices over it can lead to a compressor replacement. Replacing your compressor could cost as much as a downpayment on a new system. Actually, many homeowners are forced to decide between installing a new system and repairing the damaged model. If you follow the steps above and quickly call a ACE-certified technician, you stand a better chance of getting a less expensive emergency.
Your technician will diagnose the situation and how to avoid the issue from occurring in the future. If a leak exists (and that is rare, but possible), the leak has to be repaired or the unit will likely freeze again.
