Overall, I had an excellent experience working with Pro-tech Heating & Cooling. The company performed a service for me in the past, but most recently, I went to the company to buy some much-needed equipment for my furnace. I thought that the employees were very professional and friendly. I would recommend this company to other potential customers. I would say that the quality of the product was exactly what I needed for my furnace and everything is working well so far. I would use the company again for another service if I needed to.
