The technician at M&K Heating and Cooling Services came out promptly, diagnosed the problem, and obviously I've got the air conditioning functioning perfectly as it should have been. I was dealing with a warranty company that sent three contractors that failed to diagnose the problem--except for M&K.

I liked that they come out equipped with obviously the correct equipment--such as a simple thing like a ladder to get on the roof--because I live in a unique three-story building. Their company truck was clean and labeled, and the technicians were clean and wore uniforms. And when you call the office, they answer immediately--and that's another nice part of dealing with them. I also liked getting the scheduling follow up calls from the office and technician. They are great people.
