Not having air condition for a few days is not easy in DC. I phoned Marvin during the week to see if he did work on Saturdays-he did and quoted me a price for the service call. His fee was much lower than the other companies I called. He was prompt and with in the time frame he quoted me. It was a very easy electrical problem from him to fix. He was at the house about an hour but only charged me the service call. He could have told me it was an expensive part to fix but told me it was a simple reset button. I will definately use him again!
