Flanders Heating & Air Conditioning has done a lot for work for me, and they have always been very reliable. They came out a few days ago to install a flue pipe for me, and they did a good job on that. Then today, I woke up and there was no heat in the house. My oil burner had malfunctioned. I called them and they came out promptly and took of that for me! I was very pleased with how quickly they responded. They are a good company and their techs are very professional!
