Summer’s coming (believe it or not) and here's an often cited scenario with the average homeowner: They’re sitting in their house, minding their own business, having a bowl of popcorn and watching their favorite TV show, when suddenly he/she hears awful sound; drip... drip... drip. They look over to see the dog licking at a puddle that's gradually forming on the kitchen floor. In a flash: Anxiety, stress, and that sinking feeling. What caused the leak?; water heater, leaky toilet, shower, faucet? No – the central air conditioner is frozen solid. This can occur anywhere, from Savannah to Timbuktu, 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 Savannah area home. Usually there are two factors why 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 cannot operate to properly dissipate heat, and in essence '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 just turned into an old-school icebox.
What Should You Do When Your A/C Freezes?
- Turn the system completely off at the thermostat, and do not increase the thermostat temperature as a way to melt the frost on the coils. It is important that 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 confirm that they are not impeded by furniture or drapery.
- Call Coastal Service Experts. 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 become a costly repair. When your AC freezes over it can lead to a totaled compressor. Replacing your compressor could cost as much as a downpayment on a high efficiency model. Actually, many people are forced to decide between installing a new system and repairing the old unit. If you act quickly and call a ACE-certified technician, you stand a better chance of getting a less expensive emergency.
Your technician will advise you of the exact cause 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.
