Summer’s coming (as hard as it is to believe right now) and here's an all-to-familiar scenario with the average homeowner: They’re at home, minding their own business, happily indulging a bowl of popcorn and watching Netflix, when they notice that awful sound; drip... drip... drip. They look over to see the household pet licking at a puddle that's slowly forming on the kitchen floor. Suddenly: Worry, stress, and that sinking 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 Charleston to Africa, regardless of climate.
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 Charleston area home. The two main reasons why the evaporator coil may freeze:
- Restricted air flow
- Lack of sufficient refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil cannot operate to properly dissipate heat, and in effect 'overcools' itself. The impact of this super-cooling is condensation (that's water formation), and eventually ice forms from that condensation as it cools below the freezing point. In short, the A/C transformed into an old-school icebox.
What Might You Do When Your A/C Freezes?
- Turn the A/C completely off at the thermostat, and don’t try to thaw the system by increasing the temperature at 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 and replace any return air filters. Open all the registers completely and ensure that they are not obstructed by furniture or curtains.
- Call Pardee Service Experts Heating & Air Conditioning. The air conditioning system needs to be professionally inspected 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 lead to a costly repair. When your AC freezes over it can lead to damage to the compressor. Replacing your compressor could easily cost as much as a downpayment on a new system. In fact, many homeowners are forced to choose between installing a new system vs repairing the damaged one. If you act quickly and call a NATE-certified technician, you stand a better chance of having a less expensive job. Your technician will quickly analyze the problem 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 probably freeze again.
