About

Longmont, CO’s Go-To HVAC Company for Over 35 Years


About SAC Mechanical: HVAC Contractors in Longmont CO - sub-contentSAC Mechanical was founded in April of 1982 in Greeley, Colorado, by Sam Ainsworth and Sam Ainsworth Jr. 

The business originally started as a commercial HVAC service provider. In 1984, our company became incorporated as Sam Ainsworth & Company Mechanical Contractors, Inc. The company then expanded its service base to include restaurant HVAC and cooking equipment, ice machines, as well as some residential new construction projects.

Our Values:

  • Provide maximum customer satisfaction
  • Operate honestly and with integrity
  • Provide employees with a safe and rewarding environment
  • Operate as a team with customer satisfaction as our focus

In the late 1980’s, our company refocused its efforts to concentrate on residential and light commercial service, repairs, preventive maintenance and add-ons/replacements. We sold many brands of equipment in the late 1980’s, including Whirlpool, Tempstar and York. In 1991, the company switched to Trane as its primary brand choice of residential and light commercial equipment.

During the mid-1990’s, we became an Aire-Serv Dealer. This allowed us to incorporate business systems and processes, as well as profitable business strategies. Aire-Serv also provided a much-needed avenue into the residential indoor air quality business sector. In 2002, Trane became a partner with The Home Depot to provide heating and air conditioning installations through their “At Home Services” department. As a Trane dealer, we embraced this way of marketing and lead generation available exclusively through these two companies. 

Due to health reasons, the corporation was sold to Kevin J. Kirk and Scott J. Kirk in May of 2007. Kevin served as the general manager of Cooper Heating and Cooling in Broomfield, CO for over thirteen years and has been in the HVAC industry for over thirty years. Scott has worked for the Carrier Corporation and the Trane Company as a manufacturer representative and business trainer for the last eleven years and has been in the industry for over twenty-five years.
