What our customers are saying

Derrick the sales person was responsive, knowledgeable and gave me a very fair estimate. Derrick schedule my new furnace and air conditioner as quick as possible. Nathan and Lucas the installers showed up early to start work and both worked hard all day. Nathan and Lucas were professional the whole time at my house. The new furnace and air conditioner works great and the install is clean. I recommend Assurance Heating and Air Conditioning. David C.

Assurance was great and very quickly fit me into the schedule for my broken air conditioning. They were nice enough to call 30 min ahead so I didn’t have to wait home and came within the window that I was told. Herman Damore was honest and friendly and showed me exactly what he was checking and why it wasn’t working. I highly recommend Assurance and Herman! Laura M.
