B & B Heating & Cooling

B & B Heating & Cooling has kept Florissant and St. Charles comfortable since 1985. This family-owned contractor holds a 4.9-star average across 1,326 reviews, a volume that reflects decades of steady local presence. The company operates 24/7 with same-day emergency service, serving Florissant, St. Charles, and surrounding communities including Chesterfield, Hazelwood, O'Fallon, and Ferguson. Their technicians handle heating, cooling, plumbing, and electrical needs for both residential and light commercial properties.

What sets B & B apart is their Lennox Network Dealer status and the industry recognition that comes with it. They have earned both the Centurion Award and Partner of the Year Award from Lennox, distinctions that reflect excellence in installation quality and customer satisfaction. The company offers financing with 12 months no interest on new Lennox systems, plus rebates up to $1,800 on the Ultimate Comfort System. Their indoor air quality lineup includes the Lennox Healthy Climate Solutions line, covering air filtration, ventilation, and humidity control for year-round comfort.

Customer reviews name two technicians who consistently earn praise. Chris arrived same-day for Adam Ketterer's AC repair during a heat wave and had the system cooling within an hour, avoiding a premature replacement. Nick Krumwiede similarly describes Chris arriving the same day for a furnace failure, completing the repair in under an hour while checking for aging components without upselling. One negative review from 2025 mentions installation drywall damage and an unfulfilled thermostat promise, issues the company has not publicly addressed.
