SAC Mechanical

SAC Mechanical is a HVAC repair company. Sam Ainsworth and Company Mechanical Contractors, Inc. serves all of Longmont, Colorado and the surrounding areas. They offer a variety of equipment repair services. Since its founding in 1982, the company has served as an official commercial HVAC service provider. Sam Ainsworth and Sam Ainsworth Jr. worked as a dedicated father and son team for many years. At that point they mainly worked on commercial projects. Soon, they expanded their work from repairing HVAC to include other related machinery, like cooking equipment and ice machines. In the late 1980’s, they started to focus more on residential repair and maintenance, though they still performed some light commercial repair and installation. This new work included repairs, but also preventive maintenance.

In 1991, SAC switched to the Trane Brand as its first choice for all HVAC equipment. Due to health reasons, the Ainsworths had to sell their business to another father/son team. In 2017 Kevin J. Kirk and Scott J. Kirk took over full operation of the bushiness. The new father/son team honors the tradition of excellence set by Ainworth family. They continue to provide the quality service that their clientele has learned to expect. Kevin J. Kirk and Scott J. Kirk pride themselves in carrying on the SAC standard of great service.
