We needed to replace our 25 year old furnace, and contacted Coad based on a friend's recommendation. Gary was extremely knowledgeable, prompt and came in with the best price out of all the companies we got quotes from. We were originally looking at a high-efficiency furnace, which Gary could have sold us & made a lot more money. However, he advised that a mid-efficiency unit would be the best option, given the size of our house. We were so pleased with the service, we hired him to service our Central Air unit also!
