I had house guest visiting for a week when a bank of lights went out. I tried to reset all the breakers, but couldn't get the lights to work. I was worried about an electrical short starting a fire. I called K & H Electric and explained the problem. They told me they could send someone out that same day and would call me 30 minutes before their arrival. The technician checked all the circuits and found a bad wall socket. He fixed the problem in an hour. Thanks for the quick response time !! Rick Green Huntingtown, Maryland
