I have always had a good experience with Minuteman Heating And Air. I did have a debacle when I first purchased my unit, but that was more of a manufacturer defect. Once I spoke to the owner of Minuteman however, they took responsibility in working with the manufacturer of my system to have it replaced, that way we wouldn't have to go back and forth to troubleshoot the problem and get nowhere. They have always been very helpful, replacing my filter whenever they come out to service my system. They seem to be doing a good, thorough job, and I never get the impression that they're holding anything back when there's a potential issue, nor does it feel like they're looking for an excuse to charge me more money. I trust them and will continue to use their honest service.
