Certus Mechanical Heating & Air

Certus Mechanical Heating & Air has earned a perfect 5.0-star rating across 152 reviews in Chattanooga, Tennessee. Mike and his crew operate this family-owned contracting business from the Scenic City, serving both residential homeowners and commercial property managers throughout the region. The team holds the credentials and industry experience that Chattanoogans look for when the summer humidity climbs or a winter freeze threatens the heating system.

The reviews paint a consistent picture: Certus Mechanical responds the same day you call and handles warranty claims with the manufacturer directly, saving homeowners the headache of filing paperwork themselves. Technicians arrive on time, walk you through the diagnosis in plain language, and complete the repair without padding the invoice. That straightforward approach, paired with professional conduct on the job site, explains the perfect rating and the steady stream of repeat customers.

Troy Ray has entrusted Certus Mechanical with his personal home and multiple rental properties for over ten years, a relationship built on reliability and honest work. Margaret DeStefano described a same-day arrival during a pressing breakdown, a warranty part handled entirely on her behalf, and a follow-up installation that arrived exactly when Mike promised it would. Zac and Ethan recently diagnosed and repaired an upstairs HVAC unit for Wayne Smith, delivering a clear explanation of the problem and the fix before leaving the home clean. Across every review, technicians are named and the work speaks for itself.
