Summer’s coming (as hard as it is to believe right now) and here's an all-to-familiar scenario with the average homeowner: They’re relaxing in their living room, minding their own business, enjoying a bowl of popcorn and watching Netflix, when suddenly he/she hears dreadful sound; drip... drip... drip. They turn their head to see the cat licking at a puddle that's steadily forming on the bathroom floor. Just like that, the mood changes: Worry, stress, and that “how much will this cost?” feeling. How did the leak start?; water heater, leaky toilet, shower, faucet? Not necessarily – the central air conditioner is frozen solid. This can strike anywhere, from Rochester to Timbuktu, 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 Rochester area home. There are two primary reasons the evaporator coil may freeze:
- Restricted air flow
- Low refrigerant
Either way, the ending effect is that the air conditioner's evaporator coil will be unable to properly dissipate heat, and in essence '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 transformed into an old-school icebox.
What Can You Do When Your A/C Freezes?
- Turn the A/C completely off at the thermostat, and do not increase the thermostat temperature as a way to melt the frost on the coils. 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 and replace any return air filters. Open all the registers completely and confirm that they are not obstructed by furniture or curtains.
- Call Strogen's Service Experts. The air conditioning system needs to be inspected by a NATE-certified professional 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 become an expensive repair. When your AC ices over it can lead to a compressor replacement. Replacing your compressor can cost as much as a downpayment on a brand new air conditioner. Actually, many people are forced to pick between installing a new system or repairing the old one. If you follow the steps above and quickly call a NATE-certified technician, you stand a better chance of getting a less expensive job. Your technician will advise you of the exact cause 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.
