McCreery & Sun of Colorado

McCreery & Sun of Colorado has kept Greeley residents comfortable since 1974, making it one of the longest-running family-owned HVAC contractors in Weld County. The company holds a 4.9-star rating from 190 reviews, reflecting decades of consistent service in a community where summer highs routinely exceed 90 degrees and winter lows plunge below zero. Based at 3455 F Street Unit 3 in Greeley, the contractor serves the broader Northern Colorado region including Evans, Windsor, and Milliken. The business employs technicians who handle both residential and light commercial projects, offering a one-stop solution for heating, cooling, and water heating needs under a single roof.

What distinguishes McCreery & Sun from newer competitors is their comprehensive service model and availability. The company maintains 24-hour emergency service, a critical feature when a furnace fails on a holiday weekend or an AC unit dies during a heat wave. Their offerings extend beyond traditional HVAC work to include solar energy installation and water heater services, allowing homeowners to bundle energy upgrades. The company also handles permitting and pulls required mechanical permits for installations, a step some contractors skip. Customer reviews reference high-efficiency furnace rebates, suggesting the team assists homeowners with utility incentive paperwork, adding tangible value to new equipment purchases.

Customer stories from verified reviews reveal the human side of this contractor. Reviewer Lynette N. described how estimator Scott Butterworth examined her existing furnace and provided maintenance advice rather than pushing for an expensive replacement, a decision that saved her thousands. When Barb F. sought replacement quotes, she found McCreery & Sun pulled permits, offered transparent equipment specifications, and followed up post-installation to handle final inspections and rebate paperwork. During a January 2026 holiday weekend, technician Nate responded to an emergency call, diagnosed a pressure switch issue, and followed up days later with the repair while also identifying an incorrectly sized air filter the previous owner had installed. These scenarios illustrate a contractor who treats each service call as an opportunity to educate homeowners and build long-term relationships.
