Cummins Heating & Air

Cummins Heating & Air keeps Dewey and Bartlesville comfortable with a perfect 5.0-star rating across 161 reviews. Since 1980, this locally owned contractor has specialized in reliable heating and cooling solutions for Northeastern Oklahoma homes and businesses, tackling the region's extreme temperature swings from freezing winters to humid summer heat waves.

The company partners with Carrier, a trusted name in heating and cooling equipment, to deliver durable and efficient systems. What distinguishes Cummins is their same-day emergency service and a satisfaction guarantee that backs every job. Their technicians also handle indoor air quality solutions including UV lights, advanced filtration, and duct repair alongside blown-in insulation for improved energy efficiency.

Reviewers consistently praise specific team members. Phil arrived promptly to diagnose a sweating duct issue, while Jim, Brandon, and Tyler completed the insulation replacement with thoroughness, checking for additional water sources beyond the immediate problem. Another reviewer noted a service tech arrived within an hour of their call during extreme heat, explaining everything and restoring heating in under an hour at reasonable cost.
