Claim This BusinessTom Lalonde founded Lalonde Heating Cooling in Idaho Springs, Colorado, building a heating and cooling company that has earned a 4.9-star rating across 12 verified client reviews. The locally owned contractor serves the mountain communities of Clear Creek County including Idaho Springs, St. Mary's, and the surrounding high-country neighborhoods where winter temperatures demand reliable furnace performance. Licensed and insured, the team handles residential heating systems, boiler installations, and emergency furnace repairs across the region.
What distinguishes Lalonde Heating Cooling is the team's commitment to fixing systems other contractors declare beyond repair. Multiple reviewers recount instances where competing companies quoted astronomical replacement costs only to have Lalonde technicians diagnose and repair the existing equipment for a fraction of the price. The owner, Tom Lalonde, personally invests time explaining system operations to homeowners in understandable terms while his crew members including Billy and Dustin execute installations with notable efficiency, completing boiler replacements in under two days.
Customer stories reveal the responsive service that defines this contractor. When one reviewer experienced a furnace failure during a blizzard, Lalonde's crew arrived and completed the replacement despite severe weather conditions. Another client received same-day Saturday service after calling about a heating emergency early that morning, with technician Billy diagnosing the issue, locating parts that same day, and returning Sunday to complete repairs while providing a temporary heater in the interim. A third reviewer noted that Billy identified underperforming propane burners and replaced all four blower components to restore full heating capacity.
All 12 reviewers award 5-star ratings, with three clients specifically naming technicians Billy and Dustin alongside owner Tom Lalonde. Four reviewers mention emergency or same-day service experiences, while two customers describe how Lalonde saved them thousands by repairing systems other contractors said required complete replacement.
