About Extreme Heating & Air Conditioning
Extreme Heating & Air Conditioning has served homeowners in Mason, Ohio, and nearby communities such as Beavercreek for several years. As a family owned, locally operated business, they hold the necessary Ohio HVAC contractor licenses and maintain a 4.9 star rating across 594 online reviews, reflecting a commitment to transparent diagnostics and quality craftsmanship. Their service fleet covers residential heating, cooling, and indoor air quality solutions, with a focus on responsive scheduling throughout the greater Cincinnati region.
What separates Extreme Heating & Air Conditioning is their hands on approach to complex system replacements. Their crews handle custom sheet metal fabrication in house, fabricating new ductwork, running new line sets, modifying gas piping, and neatly terminating wiring, and all work is often subcontracted by larger firms. Because they own their parts inventory, technicians can complete most repairs during a single visit, reducing wait times. They also pledge a workmanship warranty on every installation, giving homeowners confidence that the job meets or exceeds manufacturer standards.
Customer stories highlight rapid response and personalized care. When a Mason family's furnace failed completely on a cold Sunday, technicians Tristan and Mike arrived within twelve hours, assessed the damage, and installed a new heat pump system from scratch, including custom ductwork and gas line modifications, finishing the job in one day. Another homeowner praised technician Austin for arriving on time, explaining each step, and offering multiple service options without high pressure sales tactics, a sentiment echoed by dozens of reviewers.
