Our air conditioner was making a loud unusual noise. I called George on Saturday. He had recently worked on our air conditioner for a different issue. He came between his other jobs and quickly diagnosed the problem. We needed a new fan motor. George said he would try and get one but there was only one supplier open on Saturday. He said he would be back on Tuesday if he could get the part. Of course the temperature has been in the 90s and would be for the next week. Later that same day George called and said he had the part and if we were home he would install the new fan motor. Within a couple of hours he had the air conditioner working and checked out. Again he did this between jobs. George could have just waited until Tuesday. George is very hard working and knowledgeable of what he does. He is pleasant and easy to work with. I would highly recommend him to anyone needing AC repairs.

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.

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!
