I have been using Pro-tech Heating & Cooling for a few years now, and recently, I had them put in a new central air conditioning system in my home. It was a good experience, and the installers that came over were nice, friendly, and polite. The company is always prompt with their service when you call and need their help. Also, their prices are a lot better than other companies I have used before, which is why I go with Pro-tech and will continue to use them in the future.
