Dwight installed our furnace 6 years ago and we have called him several times since for AC issues at our son’s property (our furnace has never had any problems). From Day One he has been the most professional, conscientious, honest, personable, responsive service professional we have ever met. He explains the problem in terms we can understand. His work is perfect. His rates are reasonable. I would recommend him without hesitation.
