Cornett's Heating and Air Conditioning

Cornett's Heating and Air Conditioning has kept Hamilton and surrounding Butler County homes comfortable since 1987, making it a fixture in the community for nearly four decades. The company holds Ohio license number 22468 and maintains a strong 4.6-star average across ten customer reviews. Serving Hamilton, Fairfield, West Chester, Middletown, and Springdale, this family-owned contractor handles residential, commercial, and new construction projects. Their headquarters sits at 6961 Morris Road in Hamilton, and they operate 24-hour availability Monday through Friday for emergencies.

What distinguishes Cornett's is their embrace of modern comfort technology alongside traditional HVAC service. As an Amana dealer, they install and service heat pumps, ductless mini-split systems, and smart thermostats controllable via smartphone apps. Sarah Laflin's review specifically mentions a heat pump installation paired with an app-connected thermostat, reflecting current homeowner demand for remote temperature management. The company also addresses indoor air quality through air purifiers, UV coil purifiers, whole-house dehumidifiers, and HEPA filtration systems, a comprehensive approach that treats air, not just temperature.

Customer stories reveal why Cornett's earns loyalty. Amanda Ruby describes Tony Cornett leaving his only off day to diagnose her suddenly-failing AC unit and restore cooling on short notice. Another reviewer, Peter, recounts calling multiple companies without success before John's one-hour diagnosis resolved a persistent AC problem. These narratives illustrate a commitment to solving difficult problems rather than simply cycling through standard procedures.
