Dieter Heating & Air Conditioning

Dieter Heating & Air Conditioning is a family-owned HVAC contractor based in Canfield, Ohio, serving Mahoning County and surrounding communities. Bob Dieter, known professionally as "Dieter the Heater," apprenticed under his father and has built a reputation over 40 years of hands-on service. The business maintains a 4.2-star rating across 25 Google reviews, with customers noting reliable same-day response times and straightforward advice about equipment repairs.

This contractor distinguishes itself through specialized product offerings and round-the-clock availability. As a dealer of Fujitsu Mini Splits and Weil McLain boilers, they handle systems that many regional contractors avoid. Their indoor air quality division addresses humidity control with both humidifiers and dehumidifiers, while the office staff facilitates financing options for major equipment replacements. Critically, they advertise 24-hour emergency service with a dedicated after-hours line.

Customer reviews document specific scenarios where this team delivered exceptional service. When Jessica Russell detected natural gas in her basement, technicians Bob and Justin arrived within an hour, inspecting every gas connection in the home and discovering a second leak at the stove valve. Mike Splain described how Bob diagnosed a furnace issue in 15 minutes that another company claimed required a $700 part and five-day wait, saving him from a cold winter night without heat.
