Whether your home relies on an oil-fired boiler short cycling during peak freezes or you are upgrading to a ductless mini split installation with high SEER2 and HSPF2 ratings, our EPA Section 608 certified technicians deliver lasting reliability.

Manchester’s Dedicated Heating and Cooling Specialists

Granite HVAC Solutions was founded to solve the unique climate demands of southern New Hampshire. Traditional systems often struggle under rapid weather shifts, resulting in frozen condensate lines, combustion air intake safety hazards, and uneven room temperatures. We eliminate guesswork by applying static pressure testing, flue gas combustion analysis, and air elimination in hydronic loops to every installation and maintenance visit.

Located at 500 N Commercial St in Manchester, our team is committed to transparent service. We help homeowners navigate regional energy rebates, upgrade outdated electrical capacity for modern heat pumps, and maximize heating season performance without relying on high-cost secondary electric resistance heat.
