Claim Your Free PageMountain States Heat & Air Inc has served Greeley and the broader Weld County region for more than two decades as a family-owned HVAC contractor. Led by owner-operator George, the crew holds current licensing and maintains an A rating with the local builder's association. The company currently boasts a 4.6-star average across 32 verified customer reviews, with particular strength in responsiveness during extreme weather events. Service areas include Greeley, Evans, and surrounding communities across the northern Colorado plains.
What distinguishes Mountain States Heat & Air is George's hands-on approach to every service call. Without a formal website or extensive marketing, the company relies on word-of-mouth referrals and repeat customers. George performs installations and repairs personally, often squeezing same-day appointments between existing jobs during summer heat waves or winter cold snaps. The team offers standard residential heating and cooling maintenance alongside light commercial equipment work, with no advertised specialty brands or manufacturer certifications mentioned in available materials.
Customer reviews paint a picture of dedicated emergency service. During a 90-degree heat wave, George sourced a replacement fan motor on a Saturday, drove to the customer's home within hours, and had the system operational before evening. Another reviewer described how George drove three hours roundtrip after dark to repair a furnace that had failed late at night, refusing payment for the late-hour convenience. Not every experience has been perfect, one commercial client noted equipment failure and communication gaps, but the majority of reviewers praise George's technical knowledge and willingness to go the extra mile.
Three of four detailed reviews award 5 stars, with common praise for same-day emergency response and George's personal involvement in repairs. Single-year reviews mention specific scenarios: Saturday emergency during extreme heat, same-day furnace repair during a cold snap, and late-night house calls. One 1-star review cites installation quality issues and missed follow-up calls, representing the only negative feedback in the dataset.
