In 1969, ACS Air Conditioning Systems opened its doors as a Carrier dealer with the idea of providing Bay Area families and businesses with heating & air conditioning comfort solutions that fit their lifestyles, and budgets. For the past 50 years, customers have come to rely on ACS Air Conditioning Systems for their Carrier equipment and quality installations, too. As the oldest Carrier dealer in the Bay Area, ACS is proud of our many referrals from satisfied and repeat customers in the area. We continue to be a Better Business Bureau A+ contractor year after year and are licensed, bonded and fully insured for our customer’s protection. ACS is a Sheet Metal Workers Local 104 Union Shop, employing the highest trained installers and service technicians in the industry. As a Carrier Factory Authorized Dealer we are required to maintain a level of quality and professionalism to assure our customer’s peace of mind in receiving the best possible system for their home or business.
