Lincoln Heating and Air Conditioning was professional and no hard sale from preparing the estimate to the install of the replacement of our 2, 30-year-old AC units. Other businesses I contacted, were hard sale to replace our working furnaces and install new AC units at 3 to 4 times the cost of doing a retrofit to our existing working furnace units. The install crew was knowledgeable and respectful of our house during the installation process. They are a professional company that was enjoyable to work with. I would definitely recommend their services to anyone.
