My air conditioner went out when temps were in the 90's. George came at the end of the day and worked on my unit until late into the evening. He was professional, kind and worked hard. He explained things regarding my air conditioner. I understood what was going on and why. Great serviceman and human being. Thanks George!

The furnace gave up during the winter. The previous company wanted to have the chimney removed and to replace the water heater as well. George came up with some ideas for the new furnace, and the lining of the chimney and everything was done in less than two days for half of the cost the other company quoted. The inspector was very impressed. George is one of the kindest and nicest people one might meet who will do anything to help the best way possible.
