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 sitting in their house, minding their own business, happily indulging a bowl of popcorn and watching Netflix, when suddenly he/she hears dreadful sound; drip... drip... drip. They look over to see the dog licking at a puddle that's slowly forming on the dining room floor. In a flash: Worry, stress, and that ”oh brother!” feeling. Where did the leak come from?; water heater, leaky toilet, shower, faucet? Not necessarily – the air conditioning equipment may be frozen. This can occur anywhere, from Tempe to Timbuktu, 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 Tempe area home. There are two primary reasons the evaporator coil may freeze:
- Restricted air flow
- Insufficient refrigerant
Either way, the outcome is that the air conditioner's evaporator coil cannot operate to properly disperse the heat, and in essence 'overcools' itself. The result 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 has morphed into an old-school icebox.
What Can You Do When Your A/C Freezes?
- Turn the system 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.
- 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 obstructed by furniture or curtains.
- Call Bob Brown Service Experts. The air conditioning system needs to be inspected by a ACE-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 a costly repair. When your air conditioner freezes over it can lead to a totaled compressor. Replacing your compressor could cost as much as a downpayment on a new system. Actually, many people are forced to pick between installing a new system and repairing the old unit. If you act quickly and call a ACE-certified technician, you have better odds of getting a less expensive repair. Your technician will diagnose the situation and how to avoid the issue from repeating 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.
