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, happily indulging a bowl of popcorn and watching Netflix, when they notice that dreadful sound; drip... drip... drip. They look over to see the household pet licking at a puddle that's gradually forming on the dining room floor. Suddenly: Worry, stress, and that ”oh brother!” feeling. Where did the leak come from?; water heater, leaky toilet, shower, faucet? No – it's the air conditioner of all things. This can happen anywhere, from Elkhart to Africa, regardless of summer heat.
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 Elkhart area home. There are two primary reasons the evaporator coil may freeze:
- The restriction of the system’s airflow
- Insufficient refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil does not properly dissipate heat, and in essence '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 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 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 and replace any return air filters. Open all the registers completely and verify that they are not obstructed by furniture or curtains.
- Call BW/Cook 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 turn into a costly repair. When your AC ices over it can lead to a totaled compressor. Replacing your compressor can cost as much as a downpayment on a high efficiency model. Unfortunately, many homeowners are forced to pick between installing a new system vs repairing the damaged model. If you follow the steps above and quickly call a NATE-certified technician, you stand a better chance of getting a less expensive repair. Your technician will quickly analyze the problem 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 likely freeze again.
