A short history
Our roots go back to 1977 and to locally owned heating and cooling companies serving Puget Sound homes, including MM Comfort Systems in Redmond, G&S Heating & Cooling in Everett and Sullivan Heating & Cooling in Bremerton. In 2022 they came together as Home Comfort Alliance. Since 2026 our headquarters has been in Sumner, at 1524 45th St E, Suite 102. Read our full history.
