When we replaced our heating & air, Monthie Mechanical not only came in with the most reasonable bid, but provided the most logical solution when it came to fixing a return air flow problem. They were friendly, prompt, professional, and we've never had a single problem in with the heat/air in the years since. When we were getting estimates, they could answer our technical questions, and provided a detailed written contract. They even vacuumed up after themselves before leaving. Excellent service, excellent price.
