A/C Repair | Why Your Home's A/C Freezes Up In Summer

A/C Repair

A/C Repair – Summer’s coming (as hard as it is to believe right now) and here’s an often cited scenario with the average area homeowner: They’re sitting in their house, minding their own business, having a bowl of popcorn and watching Netflix, 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 bathroom floor. In a flash: Anxiety, 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. But, Air Quality Control offers hope.

How 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 area home. The two main reasons why the evaporator coil may freeze:

1.  Airflow restriction, or

2.  Insufficient refrigerant

Either way, the ending effect is that the air conditioner’s evaporator coil cannot operate to properly transfer heat, and in essence ‘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. Yep, the A/C transformed into an old-school icebox.

What Should You Do When Your A/C Freezes?

1.  Turn the unit completely off at the thermostat, and don’t try to thaw the system by increasing the temperature at the thermostat. Just make sure the A/C system is completely OFF.

2.  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 drapes.

3.  Call Air Quality Control. 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 body right away.

Your technician will diagnose the situation and how to avoid the issue from occurring in the future. If a leak is present (and that is rare, but possible), the leak has to be repaired or the unit will probably freeze again.
