How to Fix a Frozen Air Conditioner 

Summer’s coming (as hard as it is to believe right now) and here’s an often cited scenario with the average homeowner: They’re sitting in their house, minding their own business, enjoying a bowl of popcorn and watching Netflix, when all of a sudden – that distant awful sound; drip… drip… drip. They turn their head to see the dog licking at a puddle that’s gradually forming on the dining room floor. Just like that, the mood changes: Anxiety, stress, and that ”oh brother!” feeling. How did the leak start?; water heater, leaky toilet, shower, faucet? Nope – the air conditioning equipment may be frozen. This can strike anywhere, from Columbus to Timbuktu, regardless of climate. 

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

  1. The restriction of the system’s airflow 
  1. Low refrigerant 

Either way, the outcome is that the air conditioner’s evaporator coil does not properly disperse the heat, and in effect ‘overcools’ itself. The result of this super-cooling is condensation (that’s water formation), and over time ice forms from that condensation as it cools below the freezing point. Yep, the A/C just turned into an old-school icebox. 

What Should You Do When Your A/C Freezes? 

  • Turn the unit completely off at the thermostat, and don’t try to thaw the system by increasing the temperature at the thermostat. 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 as well as any return air filters. Open all the registers completely and verify that they are not impeded by furniture or drapery. 
  • Call Stevenson Service Experts. The air conditioning system needs to be inspected by an ACE-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 unit ices 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 homeowners are forced to pick between installing a new system or repairing the old unit. If you act quickly and call a ACE-certified technician, you have better odds of getting a less expensive repair. 

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