Summer’s coming (believe it or not) and here's an all-to-familiar scenario with the average homeowner: They’re at home, minding their own business, enjoying a bowl of popcorn and watching Netflix, when suddenly he/she hears terrible sound; drip... drip... drip. They glance over to see the cat licking at a puddle that's steadily forming on the bathroom floor. In a flash: Worry, stress, and that ”oh brother!” feeling. What caused the leak?; water heater, leaky toilet, shower, faucet? Nope – the central air conditioner is frozen solid. This can happen anywhere, from Dallas to Thailand, regardless of climate.
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 Dallas area home. The two main reasons why the evaporator coil may freeze:
- Restricted air flow
- Lack of sufficient refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil does not properly dissipate heat, and consequently 'overcools' itself. The impact of this super-cooling is condensation (that's water formation), and eventually ice forms from that condensation as it cools below the freezing point. Yep, the A/C has morphed into an old-school icebox.
What Might 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. Just make sure 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 as well as any return air filters. Open all the registers completely and verify that they are not impeded by furniture or curtains.
- Call Levy & Son 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 damage to the compressor. Replacing your compressor could easily cost as much as a downpayment on a brand new air conditioner. Unfortunately, many homeowners are forced to pick between installing a new system vs repairing the damaged unit. If you act quickly and call a NATE-certified technician, you stand a better chance of having a less expensive repair. Your technician will quickly analyze the problem and how to avoid the issue from occurring 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.
