Summer’s coming (we promise) and here's a common scenario with the average homeowner: They’re relaxing in their living room, minding their own business, enjoying a bowl of popcorn and watching a movie, when they notice that awful sound; drip... drip... drip. They glance over to see the cat licking at a puddle that's slowly forming on the dining room floor. Suddenly: Concern, stress, and that “how much will this cost?” 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 Sharonville 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 Sharonville area home. The two main reasons why the evaporator coil may freeze:
- The restriction of the system’s airflow
- Low refrigerant
Either way, the outcome is that the air conditioner's evaporator coil cannot operate to 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. In other words, the A/C just turned into an old-school icebox.
What Might 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.
- Do what you can to ensure airflow is not restricted. 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 drapery.
- Call Knochelmann Service Experts. 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 become an expensive repair. When your air conditioner freezes over it can lead to a compressor replacement. Replacing your compressor could easily cost as much as a downpayment on a brand new air conditioner. Unfortunately, many people are forced to pick between installing a new system vs repairing the old unit. 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 diagnose the situation and how to avoid the issue from repeating in the future. If a leak is present (and that is rare, but possible), the leak has to be repaired or the unit will likely freeze again.
