“Dave came out same day for a no-cool emergency. Found the bad capacitor, replaced it on the truck, back to running in under an hour. Honest pricing, no upsell.”
M. R. of Kingfisher, OK
⭐⭐⭐⭐⭐
“Hartzell’s installed our geothermal system in 2018. Eight years in, zero problems and the electric bill cut in half. Dave knows geothermal like nobody else around here.”
S. L. of Hennessey, OK
⭐⭐⭐⭐⭐
“Called three other HVAC companies before Hartzell’s. Dave was the only one who walked through the problem with me and explained the repair before he started. Saved me from a $12,000 replacement quote.”
J. W. of Okarche, OK
⭐⭐⭐⭐⭐
“On Dave’s 360 maintenance plan for three years now. Spring and fall tune-ups keep my system running tight. Worth every penny of the $360.”
T. B. of Piedmont, OK
Why 4.8 Stars Matters
I’m not the cheapest HVAC company in Kingfisher. I’m not trying to be. The 4.8 rating across 290+ reviews means most customers feel they got a fair shake and the work held up. That’s the standard I work to every job.
