Burkhardt has on our go to company since we bought our house. They removed the old furnace and installed two new furnaces for the duplex. When we added air conditioning, they gave us a fair price and did a great job. Over the years, we have had to have the furnaces service as well as had annual tune ups. Each time the service tech was prompt and courteous and did a great job I would recommend them wholeheartedly without reservations. In fact I have to several friends.
