Bob is an expert craftsman. He is honest, fast and knowledgeable. Most importantly he understands safety. On more than one occasion Bob was able to uncover a gas leak and a subsequent exhaust leak. He was very concerned about our welfare and he recommended a cost effective solution and fixed the problem immediately. He is also great working with other, equally talented contractors to get the job done and at incredibly reasonable rates. He recommended a terrific service for cleaning our air ducts. We highly recommend Bob for your heating and air conditioner needs. He's a true professional and you couldn't find a more reasonable, reliable resource. Thanks Bob! All toasty warm now with clean air to breathe. :)
