So you’ve taken to turning on the air conditioner on another scorching Oklahoma summer day, only to find the cool air you need to keep your home from feeling like another “hot yoga” studio isn’t flowing out of your vents. A quick trip to investigate the “case of the missing cool” uncovers that there is ice forming on your AC coils.
As a concerned, frustrated undoubtedly and sweaty homeowner here in the Lawton, Oklahoma area, you want answers to how you can unfreeze an air conditioner, and get back to relaxing in the summer oasis you call your home.
What Causes an Air Conditioner to Ice Up?
The job of your air conditioner isn’t just to create cold air, it is also designed to remove heat from the air. And there are times where your air conditioner may actually be too good at doing both! As the hot ambient air of the air conditioner intake is sent to the outdoor unit via refrigerant line, the heat is removed (using refrigerant liquid/gas that your system is charged with.) When that heat is removed, the now cooled air is sent back into your home through ductwork and vents.
When that air gets cold enough, it starts to turn any of the ambient moisture around the evaporator coils into ice crystals. In a surprisingly short time, those small ice crystals turn into lots of frost, restricting all airflow from your outdoor unit into your home and stopping your air conditioners cooling power dead in its tracks.
There can be a few things that cause your air conditioner to freeze up this way, including:
An improperly sized AC unit
Air flow issues (poor ductwork design or intake obstructions)
Low refrigerant levels/leaks
What To Do If Your Air Conditioner is Frozen
Now that you know how the ice may be forming in your cooling system, you probably want to know what to do about it.
Step 1: Turn off your air conditioner
Walk to the thermostat, and switch it from the “cool” setting or “auto mode” to the “fan only” mode. This will prevent any more ice from forming in the short term, and will allow the ice to melt.
Step 2: Wait!
Unfortunately, there isn't much else you can do but wait for the ice to melt! The ice is what is obstructing the airflow, and until that is gone you won’t be able to use your air conditioner.
Step 3: Call an HVAC professional
After the ice has melted, you may have fixed the problem in the short term. But there is still going to be ambient moisture present in your air conditioner, and the underlying issue with your air conditioner will most likely persist in freezing up your condenser coil. Scheduling professional AC repair & maintenance will diagnose and resolve the issue!
