HVAC Services & Heat Pump Solutions in Bellingham, MA​

A Community Steeped in New England Charm  

Nestled between the Blackstone Valley and the Charles River watershed, Bellingham blends small-town character with easy access to Route 495 commuters. From summer strolls along the Southern New England Trunkline Trail to the crisp crunch of autumn leaves around Jennings Pond, locals know all too well how quickly our seasons shift. Winters here can bring heavy snow and below-freezing nights, while summer afternoons heat up for backyard barbecues and community events at Town Common.​

Bellingham’s annual Flag Day parade and summer concerts on the Town Common make every warm season feel like a hometown celebration.​
