Summer’s coming (believe it or not) and here's an often cited scenario with the average homeowner: They’re at home, minding their own business, having 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 cat licking at a puddle that's gradually forming on the dining room 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? Nope – it's the air conditioner of all things. This can happen anywhere, from Salt Lake City 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 Salt Lake City 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 will be unable to properly transfer heat, and in essence 'overcools' itself. The net effect 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. Yep, the A/C transformed into an old-school icebox.
What Might You Do When Your A/C Freezes?
- Turn the system completely off at the thermostat, and do not just move up the temperature on the thermostat. Ensure 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 and replace any return air filters. Open all the registers completely and ensure that they are not impeded by furniture or drapes.
- Call Service Experts Heating & Air Conditioning. 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 become a costly 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 high efficiency model. In fact, many people are forced to choose between installing a new system or repairing the damaged one. If you move fast, follow the instructions, and call a NATE-certified technician, you have better odds of getting a less expensive emergency. Your technician will diagnose the situation and how to avoid the issue from repeating 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.
