About Creators of Total Comfort Mechanical

COTC-120hCreators of Total Comfort Mechanical was founded by Robert Trainer, a Master HVAC tradesman. After years in the industry, it became clear to Robert that a contractor could be very successful by following this simple formula: provide quality work at a fair price. It was with this idea that COTC Mechanical began.

COTC Mechanical Inc. is a company comprised of highly trained and licensed tradesmen. We are dedicated not only to our clients, but also to our industry. We encourage our employees membership in the American Society of Heating and Refrigeration Engineers (ASHRAE). As a business, we are members of the Air Conditioning Contractors of America (ACCA), and work to improve trade practices and standards. We also encourage our employees to provide teaching and instruction for state apprenticeship or vocational programs.

One call to [COTC] and Robert Trainer was at my house with a very thorough and detailed estimate in the same day. Their work is extremely neat and very detailed to the T….I would give them a 6 out of 5 stars…yes they were that good. Highly, highly recommend them to anyone in need of HVAC work.
