Bel-O Cooling & Heating

Bel-O Cooling & Heating has kept homes comfortable in the Metro East region since 1959, making it one of the oldest continuously operating HVAC contractors in the area. The family-owned business holds proper licensing and maintains an outstanding 4.9-star average across 1,356 customer reviews. Based in Lebanon, Illinois, the company serves Belleville, O'Fallon, Collinsville, Glen Carbon, Edwardsville, and Fairview Heights with a full range of heating, cooling, and plumbing solutions.

What distinguishes Bel-O is its commitment to comprehensive in-house capabilities. The company operates its own sheet-metal fabrication shop, allowing custom ductwork and equipment housing without subcontracting. They carry Carrier residential equipment and Navien tankless water heaters, brands known for reliability and energy efficiency. For indoor air quality, Bel-O offers REME HALO air purifiers, a technology that actively reduces pathogens in circulating air. All work is backed by their service guarantee, and the company provides financing options for larger installations.

Customer stories from recent reviews illustrate the team's dedication. Technician Jim Gauch recently performed a gas fireplace cleaning and tuning, taking time to explain every step to the homeowner and checking the entire system for safe operation. When Sarah Beaver's heat failed during a cold spell, the company dispatched someone within a couple of hours, her repair took under 30 minutes, and the technician provided preventative recommendations without pressure. Anthony has earned repeat calls for his respectful approach and thorough explanations of furnace issues.
