STL Heating &cooling

STL Heating & Cooling is an HVACR contractor based in the Des Moines metro area with over 50 years of combined experience serving residential and commercial clients across Polk, Dallas, Jasper, Warren, Marion, Madison, Marshall, Story, and Boone counties. The company handles both new construction projects and existing property systems, positioning itself as a full-service provider for the broader central Iowa region. Their longevity in the market, combined with a 4.7-star rating from three verified reviews, signals steady local operation and repeat customer relationships.

The company offers three core service lines: heating system repair and replacement, cooling system maintenance and installation, and ventilation system design. Their heating services include diagnostic work for furnaces, with a practical guideline that units older than 15 years may benefit more from replacement than repair. For cooling, they advise that air conditioners can last up to 20 years with proper maintenance, and they assess whether repair or replacement makes more financial sense for each situation. Their ventilation work spans from large commercial shops to single-family homes, emphasizing indoor air quality as a health priority rather than just comfort.

Customer reviews consistently single out Randy as the primary contact point, describing him as honest, fair, and upfront in business dealings. One reviewer specifically contrasts STL's pricing as very reasonable compared to other companies, while another notes Randy's efficiency in completing jobs without delay. The review themes center on trustworthiness and fair pricing rather than speed or emergency response, suggesting this is a reliable, scheduled-service operation rather than a 24-hour emergency shop. The three reviews all mention Randy by name, indicating a small, owner-operated business where the proprietor handles much of the fieldwork personally.
