How to Fix a Frozen Air Conditioner
Summer’s coming (we promise) and here's a common scenario with the average homeowner: They’re sitting in their house, minding their own business, happily indulging a bowl of popcorn and watching their favorite TV show, when all of a sudden – that distant awful sound; drip... drip... drip. They glance over to see the dog licking at a puddle that's gradually forming on the kitchen floor. Suddenly: Anxiety, 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 Dayton to Africa, regardless of summer heat.
Why Air Conditioners Freeze
When a central air conditioner freezes up, what actually freezes is the condenser unit's evaporator coil. This component of the air conditioner transfers (evaporates) heat from the inside to the outside of your Dayton area home. There are two primary reasons the evaporator coil may freeze:
- The restriction of the system’s airflow
- Lack of sufficient refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil will be unable to properly dissipate heat, and consequently 'overcools' itself. The impact of this super-cooling is condensation (that's water formation), and finally ice forms from that condensation as it cools below the freezing point. In other words, the A/C transformed into an old-school icebox.
What Can 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.
- 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 ensure that they are not impeded by furniture or drapes.
- Call Stevenson 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 lead to a costly repair. When your AC ices over it can lead to a totaled compressor. Replacing your compressor could cost as much as a downpayment on a high efficiency model. In fact, many people are forced to decide between installing a new system vs repairing the old unit. If you act quickly and call a ACE-certified technician, you stand a better chance of having a less expensive job.Your technician will quickly analyze the problem and how to avoid the issue from happening again. 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.
