About Keller Heating and Cooling
Keller Heating and Cooling operates out of Overland Park, Kansas, with a perfect 5-star average across 34 client reviews. Dallas Keller handles installations, repairs, and system diagnostics for homeowners throughout the Johnson County area, including Overland Park, Leawood, and Shawnee. The contractor tackles complex remediation projects, including ductwork repairs for botched installations, and installs ductless mini-split systems alongside traditional forced-air furnace and central air conditioning service.
Client feedback points to consistent practices that set this contractor apart. Reviews repeatedly note Dallas refuses to recommend unnecessary work, offers diagnostic pricing upfront before beginning repairs, and sends photo updates throughout jobs so homeowners understand exactly what work is happening. Multiple reviewers specifically mention the absence of upselling that characterizes larger HVAC companies, with one client crediting Dallas for refusing to charge extra when he discovered a loose wire during a separate repair.
