I heard great things about Dr. Tom from friends of mine and decided to give him a call when my air conditioning unit's fan stopped working. It's a good thing i did. He came and checked everything out, replaced the old fan with a new fan and then tested everything out before he left. He's fast and efficient. My ac fan has never worked better and I will continue to call him for all my home needs. The cost depends on what you get done but everything is reasonably priced.
