AC keeps tripping the breaker...please help
About two months ago, my compressor shut off (not the blower) during a horrible storm. The unit is on the roof. Naively, I called an ac technician out and paid him $350 to show me the breaker had swiched over and he also changed the contact points on the compressor. He recommended this to avoid problems later. He said the unit looked great and should work fine and it did for a couple weeks. Well it has been steadily tripping the breaker more and more often since he left to the point (today) that I cant turn it on without tripping the breaker. When it is on, it works terrific. I plan to call the guy soon to come back. I am worried about the expense and what this means. :(
Thanks for any help.
