Welsch Heating & Cooling

Welsch Heating & Cooling has maintained continuous operation in St. Louis since 1895, making it one of the oldest family-owned HVAC contractors in the region. The company, now led by president George Butch Welsch (the great-grandson of the founder), maintains a 4.5-star average across 162 verified customer reviews. Their service area covers the Greater St. Louis metro, providing 24-hour emergency heating and cooling repairs seven days a week for both residential and commercial properties.

This contractor distinguishes itself through more than a century of institutional knowledge combined with modern equipment offerings. As a dealer that services and installs all brands without restriction, Welsch handles everything from standard split systems to geothermal heat pumps and ductless mini-split configurations. They also offer promotional financing on complete system installations, making major equipment upgrades more accessible to homeowners managing budget constraints.

Customer testimonials reveal a pattern of responsive, personalized service from named team members. John Welsch personally walked a customer through troubleshooting an AC failure during 100-degree August heat, guiding them to locate a repair part and complete fixes within 45 minutes rather than waiting for morning service. Another reviewer described receiving a technician call at 4:30 AM who diagnosed the issue, sourced a replacement part, and had the system running by 8:45 AM. Sales representative Denny Turlin received multiple mentions for transparent estimates on ductwork projects.
