Summer’s coming (as hard as it is to believe right now) and here's a typical scenario with the average homeowner: They’re at home, minding their own business, happily indulging a bowl of popcorn and watching their favorite TV show, when all of a sudden – that distant dreadful sound; drip... drip... drip. They glance over to see the cat licking at a puddle that's steadily forming on the kitchen floor. In a flash: Concern, stress, and that ”oh brother!” 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 Salt Lake City to Thailand, regardless of climate.
Why Air Conditioners Freeze
The evaporator coil is the component of a central A/C unit that actually freezes. This component of the air conditioner transfers (evaporates) heat from the inside to the outside of your Salt Lake City area home. The two main reasons why the evaporator coil may freeze:
- Airflow restriction
- Lack of sufficient refrigerant
Either way, the outcome is that the air conditioner's evaporator coil does not properly transfer heat, and in effect '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. Yep, the A/C has morphed into an old-school icebox.
What Should You Do When Your A/C Freezes?
- Turn the unit completely off at the thermostat, and do not increase the thermostat temperature as a way to melt the frost on the coils. Ensure 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 as well as any return air filters. Open all the registers completely and confirm that they are not impeded by furniture or drapery.
- Call Mountainwest Service Experts. The air conditioning system needs to be serviced by a professional that is NATE-certified 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 pricey 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. Unfortunately, many people are forced to choose between installing a new system or repairing the old one. If you act quickly and call a NATE-certified technician, you have better odds of having a less expensive emergency. 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.
