Hartzell's Heat & Air

I'm Dave Hartzell - Master HVAC technician, Kingfisher, Oklahoma. I've been doing this work for 45 years and opened   Hartzell's Heat & Air about 15 years ago after 12 years at another local shop.

We handle heating, cooling, and geothermal for homes and businesses across central Oklahoma ΓÇö Kingfisher, Blaine,   Canadian, Garfield, Logan, and Major counties. Every brand, every system.

I'm IGSHPA Accredited for geothermal installation, NATE certified, a Mitsubishi Diamond Dealer, and a Trane Comfort   Specialist. If you're looking at a geothermal system, Oklahoma utility rebates are still active in 2026 - CKenergy,   OG&E, OEC, and several co-ops. I handle the rebate paperwork.

Service calls: $99 dispatch, $111 diagnostic ΓÇö that diagnostic fee gets credited toward your repair if you approve the   work. Free estimates on new system installs.
