Google shows 4.3 stars from eight ratings, while the one detailed review available here is positive. Before booking, confirm the current scope, equipment, rebate eligibility, and who will perform the installation. BBB lists the company as not accredited and not rated, while the state license record reports active status; those records describe different aspects of the business and should be checked directly when comparing bids. Kool-Aire is a reasonable fit for homeowners seeking heating and cooling installation in the Randolph area who want to discuss heat-pump efficiency and available incentives.
Kool-Aire replaced our entire HVAC system with a new heat pump in under one day. They were extremely responsive, knowledgeable, and professional. Bob, the lead technician was very knowledgeable, and the owners reached out multiple times to make sure all of our questions were answered and that we were satisfied. Not only is our home's heating and cooling system more efficient and effective now, but replacing our old system with a new heat pump allowed us to take advantage of the state's efficiency program and receive the maximum rebate. We would definitely recommend Kool-Aire to anyone for their HVAC needs-- it was a great experience from start to finish.
