Summer’s coming (as hard as it is to believe right now) and here's a common scenario with the average homeowner: They’re at home, minding their own business, enjoying a bowl of popcorn and watching Netflix, when all of a sudden – that distant awful sound; drip... drip... drip. They glance over to see the household pet licking at a puddle that's gradually forming on the dining room floor. Suddenly: Concern, stress, and that sinking feeling. How did the leak start?; water heater, leaky toilet, shower, faucet? Nope – the air conditioning equipment may be frozen. This can happen anywhere, from Champaign to Timbuktu, regardless of summer heat.
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 Champaign area home. There are two primary reasons the evaporator coil may freeze:
- Restricted air flow
- Insufficient refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil will be unable to properly disperse the heat, and consequently 'overcools' itself. The result of this super-cooling is condensation (that's water formation), and finally ice forms from that condensation as it cools below the freezing point. Yep, the A/C just turned into an old-school icebox.
What Can You Do When Your A/C Freezes?
- Turn the A/C 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.
- Confirm that there is nothing restricting the airflow to the system. Replace the furnace or air handler's filter along with any return air filters. Open all the registers completely and ensure that they are not obstructed by furniture or drapery.
- Call Chief / Bauer Service Experts Heating & Air Conditioning. 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 costly repair. When your unit ices over it can lead to a totaled compressor. Replacing your compressor could easily cost as much as a downpayment on a brand new air conditioner. Unfortunately, many people are forced to choose between installing a new system vs repairing the old one. If you act quickly and call a NATE-certified technician, you stand a better chance of having 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 most likely freeze again.
