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 their favorite TV show, when they notice that terrible sound; drip... drip... drip. They turn their head to see the household pet licking at a puddle that's gradually forming on the dining room floor. Suddenly: Concern, stress, and that ”oh brother!” feeling. How did the leak start?; water heater, leaky toilet, shower, faucet? Nope – it's the air conditioner of all things. This can strike anywhere, from Longmont to Timbuktu, regardless of weather.
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 Longmont area home. There are two primary reasons the evaporator coil may freeze:
- Airflow restriction
- Lack of sufficient 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 net effect 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 short, the A/C just turned into an old-school icebox.
What Should You Do When Your A/C Freezes?
- Turn the system 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 along with any return air filters. Open all the registers completely and ensure that they are not obstructed by furniture or drapery.
- Call Service Experts Heating & Air Conditioning. 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 a costly repair. When your air conditioner freezes over it can lead to a compressor replacement. Replacing your compressor could cost as much as a downpayment on a high efficiency model. In fact, many people are forced to pick between installing a new system and repairing the damaged model. If you move fast, follow the instructions, and 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 happening again. If a leak is present (and that is rare, but possible), the leak has to be repaired or the unit will probably freeze again.
