GRANBY HEATING SERVICE CO. LLC

Granby Heating Service Co. LLC has anchored itself in Grand County since 1981, earning a 4.8-star rating across 98 verified reviews. The company operates from Granby and serves surrounding communities throughout the county, handling residential and light commercial heating, cooling, and ventilation projects. Their extended service hours, from 7 AM to 8 PM on weekdays and 9 AM to 7 PM on weekends, accommodate the unpredictable mountain climate where temperature swings can demand immediate HVAC attention.

What distinguishes this contractor is their Lennox dealer partnership combined with in-house custom sheet metal fabrication capabilities, a rare combination in rural mountain markets. They install RenewAire Energy Recovery Ventilators, which address the tight envelope common in mountain homes while recovering energy that would otherwise vent to the outdoors. Their planned maintenance contracts offer scheduled inspections designed to prevent mid-winter breakdowns, a practical offering given the limited contractor options during heavy snow months.

Reviewers describe two distinct scenarios: a same-day furnace repair during a busy holiday weekend handled by technician Gary, who troubleshooting patiently until resolving a recurring fault; and a reviewer noting JB arranging same-day service for a furnace computer module failure that other contractors could not diagnose. A third reviewer, himself an HVAC contractor, detailed a complex mountain home installation where only heating ductwork existed, praising the team's persistence until the system operated perfectly.
