Claim This BusinessMountain States Mechanical operates as a locally owned HVAC contractor in Windsor, Colorado, under the ownership of Christopher Legerski. The company holds an ICC Certified Master Mechanic license and maintains full licensing and insurance coverage. Serving Northern Colorado communities, the business has earned a perfect 5.0-star rating across nine verified client reviews. Operating Monday through Saturday from 7AM to 7PM, the team provides both scheduled appointments and emergency response services for residential and commercial heating and cooling needs.
What distinguishes Mountain States Mechanical from larger HVAC franchises is the direct ownership structure, clients work directly with the owner rather than a call center. The business offers a 100% Satisfaction Guarantee on every job, backed by free estimates and same-day service availability when scheduling permits. Their Peak Plan maintenance program helps homeowners prevent costly system breakdowns through seasonal tune-ups. All technicians are ICC certified, and the company handles repairs and installations across all major heating and cooling brands.
Customer testimonials consistently highlight owner Christopher Legerski's responsiveness and fair pricing. When Nancy Lee's cooling system failed during summer heat, Legerski arrived the same day and completed repairs on-site. Real estate agent Nathan Holstege has referred multiple clients to Legerski, reporting consistent positive experiences with honest assessments and competitive pricing. Eric Carver experienced a refrigerant leak on a morning that left his system non-functional; Legerski arrived that afternoon and completed repairs within an hour. Reviewers repeatedly mention the technician's thorough diagnostics and reluctance to recommend unnecessary replacements.
Eight reviewers each award five stars, with three specifically noting same-day emergency response. Four reviewers mention owner Christopher Legerski by name, and five highlight fair or competitive pricing as a distinguishing factor.
