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 suddenly he/she hears awful sound; drip... drip... drip. They look over to see the household pet licking at a puddle that's steadily forming on the kitchen floor. In a flash: Anxiety, stress, and that “how much will this cost?” feeling. Where did the leak come from?; water heater, leaky toilet, shower, faucet? No – the central air conditioner is frozen solid. This can happen anywhere, from Charleston to Africa, 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 Charleston area home. There are two primary reasons the evaporator coil may freeze:
- Airflow restriction
- Lack of sufficient refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil does not properly dissipate 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 other words, the A/C transformed into an old-school icebox.
What Can 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.
- Do what you can to ensure airflow is not restricted. 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 blocked by furniture or drapes.
- Call Pardee Service Experts. The air conditioning system needs to be inspected by a NATE-certified professional 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 an expensive repair. When your unit freezes over it can lead to damage to the compressor. Replacing your compressor could easily cost as much as a downpayment on a high efficiency model. 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 repair. Your technician will quickly analyze the problem and how to avoid the issue from happening again. If a leak exists (and that is rare, but possible), the leak has to be repaired or the unit will likely freeze again.
