The staff from Hart Heating & A/C did an excellent job at repairing my air conditioning unit. I didn't have any problems with the recent work that they did for me and I was more than happy with the results I got. I have been using the company for the past 10 years, and I would say that they are very professional and hardworking. In general, they are able to complete the work in the time frame that they say that they will complete it. I would definitely recommend them to other people. Hopefully I won't have to call them too often, but I would continue to use them if I needed to.
