Boulder Heating & AC, LLC

Boulder Heating & AC, LLC serves Boulder, Colorado and surrounding communities with heating and cooling services backed by a 4.9-star rating from 112 customer reviews. The business is owned and operated by Chris McCaleb, a Boulder native with North American Technician Excellence (NATE) certification and more than 25 years of hands-on HVAC experience. The company maintains full insurance coverage and delivers what it describes as personalized, quality, honest service to residential customers throughout the Boulder area.

This contractor distinguishes itself through a transparent business model where estimates and consultations carry a reasonable fee that converts as a credit toward any installation or replacement work proceeding after service completion. Customer reviews consistently note that Chris focuses on repairing and maintaining existing systems rather than immediately recommending unit replacements, a approach that resonates with homeowners seeking to maximize their current equipment's lifespan. The company handles furnaces, air conditioning units, boilers, water heaters, ductless mini-splits, and hydronic systems with capabilities spanning diagnosis, repair, troubleshooting, and performance optimization.

Reviewers describe specific scenarios demonstrating the company's service approach. One customer recalled Chris arriving the same day during a holiday weekend to address a failed gas boiler, completing the repair while also adjusting thermostats and other components to improve overall system efficiency. Another reviewer noted Chris thoroughly explored all diagnostic possibilities before recommending repairs, taking time to explain the underlying issues and educate the homeowner on what to monitor. A third customer mentioned Chris provided practical advice about when components needed attention versus when routine maintenance was sufficient, avoiding unnecessary upsells.
