About St. Louis Cooling & Heat Services
St. Louis Cooling & Heat Services holds a perfect 5-star rating across 15 homeowner reviews in St. Louis, Missouri. Technicians Mike and John earn repeat call-outs for clear explanations and honest estimates, while the crew has earned descriptors like knowledgeable and professional from customers across Ferguson, Brentwood, and Kirkwood neighborhoods. Founded to serve the St. Louis market, the company operates Monday through Friday from 8 AM to 8 PM and Saturdays from 9 AM to 5 PM, keeping weekday windows wide open for busy homeowners who cannot step away during work hours.
What separates this crew from other St. Louis HVAC shops is the consistency threaded through every review: a clean estimate before work begins, no padding on the final invoice, and a technician who stays until the homeowner understands the system. Mildred Sullivan reported her new heating unit cut her power bill in half, a result she attributes to proper sizing and calibration rather than a quick fix. Ethan Barnes specifically noted the crew left his dead AC running smoothly without overcharging, an experience repeated across reviews where fair pricing and honest efficiency appear side by side.
Mike arrived at Debra Freemans home, serviced her heating unit, replaced the filter, and walked her through every step without rushing. John impressed Matthew Thompson by presenting multiple repair options, explaining the cost and benefit of each, and honoring an estimate that came in below the original quote. Both technicians earned the rare review phrase I will certainly have him when needed, language that signals homeowner trust built through on-time arrival, respectful punctuality, and a clean workspace when the job concluded.
What Customers Say
14 of 15 reviews award 5 stars. Technicians Mike and John are named by 4 reviewers as the trusted professional who handled their job. Every positive review pairs fair pricing with honest, efficient service rather than upsells or delays.
