I totally recommend 5 Diamond for your heating issues. They were prompt to come out and check out my unit. My unit was over 50 years old, they even attempted to find parts, which was a nice touch. When it was beyond repair, meaning no parts on the horizon, they had a replacement unit ready for me and at a great price!! I cannot complain...excellent , prompt and professional service all the way. Fast, friendly, knowledgeable....im very happy with their service.
