Galmiche & Sons Heating & Cooling

Galmiche & Sons Heating & Cooling has kept St. Louis families comfortable since 1950, when the company began as a gutter installation business before evolving into a full-service HVAC contractor. Based in St. Louis, Missouri, this family-owned company now serves the greater metro area including nearby communities like O'Fallon and Affton. With 228 verified reviews generating a 4.4-star average rating, their reputation reflects seven decades of consistent service. The company maintains standard business hours Monday through Friday from 7 AM to 4:30 PM, with Saturday availability for urgent calls.

What distinguishes Galmiche & Sons from competitors is their manufacturer partnerships and technician credentials. They are an authorized Lennox dealer and install Goodman furnaces, giving homeowners access to major national brands with local warranty support. All service technicians hold EFA certification, and the company employs union-affiliated installers, a distinction noted in customer reviews. Their breadth covers commercial system design, residential installation, retrofits for aging equipment, and repairs across all major brands.

Customer reviews reveal a pattern of rapid response and skilled craftsmanship. When Tom Bene's mother-in-law's furnace failed during single-digit temperatures, technician Garrett arrived within an hour and had the elderly woman warm again. Dre Graham's furnace died on Christmas Day, and the team installed a replacement within two days at a lower price than competitors quoted. Multiple reviewers specifically named technicians Joe, Nick, Tim, and Garrett, praising their diagnostic accuracy and respectful home presence.
