AC Unit Freezing Up? The Next 10 Minutes Could Save You $2,000
An AC unit freezing up in the middle of August sounds like a contradiction, but it happens constantly across Tucker, Decatur, and Atlanta, and the homeowners who handle it wrong end up with compressor damage that runs $1,500 to $2,500. Here is what actually matters: turn the system completely off the moment you see ice. Not lower. Off. A running, frozen AC drives ice back toward the compressor through the refrigerant lines, and that kind of damage is often permanent. While the system thaws, pull your air filter and look at it honestly. A matted, gray filter restricts airflow and is the most common cause of freezing. Replace it, let the unit thaw fully, then restart and watch it closely. If it ices back over within a few hours, that points to a refrigerant issue and it needs a technician, not more run time.
