Clogged condensate drain lines
Why it happens here
Oakside humidity runs high most of the year, so AC systems pull a lot of moisture out of the air. That water mixes with dust and algae in the PVC condensate drain pipe and clogs it. When the drain backs up, the float switch shuts the system down.
Our approach
We flush the drain line, clear the trap, and check the pan for standing water. We also add a drain pan treatment to slow future growth. Most clogs clear in under 30 minutes.
