B&B Mechanical Services is a family-owned commercial HVAC and refrigeration contractor serving New Hampshire businesses since 2000. Facility managers, commercial property managers, and building owners call us for commercial HVAC NH repair, maintenance, and commercial refrigeration NH service. We work with businesses, not homes.

Commercial HVAC NH service covers businesses across New Hampshire. We repair and maintain commercial heating and air-conditioning systems, rooftop units, walk-in coolers, and walk-in freezers for facilities from the Seacoast and Merrimack Valley through the Lakes Region, Concord, Manchester, and Nashua. Our service territory is New Hampshire, Massachusetts excluding Cape Cod, and Rhode Island. We do not claim coverage on Cape Cod or beyond those three states.

When a rooftop unit, boiler, chiller, or walk-in system is down, request service. For planned care, ask about commercial HVAC maintenance before peak season. Related pages: Commercial HVAC Repair, HVAC Maintenance, Commercial Refrigeration Repair, and Contact Us.
