This was my first time using R&D Heating and Cooling. Chris came out to give an estimate for putting in a generator for my business. I ended up getting the generator put in by a family friend, but I will definitely be using R&D Heating and Cooling for any service needs I have in the future because my experience with Chris was so perfect. Chris was on time, very polite and well-spoken, definitely knew what he was talking about when it comes to generators.
