Lavoie Heating Service, LLC

Lavoie Heating Service delivers residential and commercial heating, ventilation, and air conditioning solutions across central Massachusetts from offices in Millbury. The company holds a 4.9-star average across 106 verified client reviews, reflecting consistent craftsmanship in installations, repairs, and system maintenance. Serving communities including Worcester, Grafton, Auburn, Sutton, and Northridge, the team responds to emergency calls throughout the region. Their workforce includes certified technicians trained to diagnose and resolve efficiency losses, refrigerant leaks, and electrical malfunctions affecting heat pumps, furnaces, and boilers.

Backup generator capabilities distinguish this contractor from standard HVAC providers. Lavoie designs and installs residential and commercial generator systems engineered to sustain power through grid failures, protecting food inventories, electronic devices, and climate control in occupied spaces. The company also handles hot water heater repair and replacement, addressing mineral buildup, rusty discharge, and relay failures that compromise domestic hot water supply. Their maintenance program includes proactive scheduling, with technicians performing tune-ups designed to extend equipment lifespan and reduce seasonal energy consumption.

Customer narratives underscore rapid response during system emergencies. One reviewer waited 48 hours without resolution from a competing company before contacting Lavoie; Dan arrived within 90 minutes, diagnosed a Goodman furnace malfunction, and restored heating on the same day. Another client required Sunday-morning assistance during a winter storm; Lavoie returned a call within five minutes and dispatched a technician who resolved the boiler issue in under an hour. Technicians named in reviews include Koby, who addressed a minisplit configuration problem, and Joey, whose thorough service-plan maintenance exceeded prior provider standards.
