• Copper tube of condenser has hole in it

    Feb.5.2012

    I signed up for a program to save money on electricity. Through this program, they installed a device that turns the air conditioning unit off/on remotely. When I came home, there was no air. The AC repair man noticed a hole blown in the middle of the copper tube of the condenser. Is it possible that the power surge caused a hole to be blown in copper tube? If so, how can I prove it and what do I need to do to prove it?

    Anything is possible, but in my experience the hole in the copper tubing would not usually be the result of a power surge. Sometimes, if there is a short in the system anywhere, the copper ends up being the ground and that usually ends up “blowing” a hole in the copper tube somewhere. It could also perhaps be caused by a wire that rubbed the insulation off and grounded out resulting in the electricity escaping through the copper to the closest ground. Of course it’s hard to diagnose without seeing the hole and tracing any shorted circuits. I recommend getting a professional HVAC contractor like ARS/Rescue Rooter to diagnose the problem. If you have the coil replaced and they don’t find the short, it’s possible for you to have more problems, if that is indeed the issue.
