Piedmont sits in Canadian County between Kingfisher and Oklahoma City. Lot sizes here trend large and homes are mostly newer construction (2000s+), which means full-system replacements and geothermal installs are common. Piedmont gets the same Oklahoma weather extremes as Kingfisher, plus more lightning strikes, surge protection pays off here.

2026 Repair Reality (Honest Pricing)
- R-454B and R-32 refrigerants now standard on new equipment. Both are mildly flammable A2L. R-454B recovery $445, R-32 recovery $395. About 50% pricier per pound than R-410A. I stock both.
- Hard Start Kit $415 installed + BEST surge protection bundle $1,225 (control board spike + transformer + in-line fuse). One $1,225 surge fix beats one $3,195 compressor replacement after Oklahoma lightning.
- Free second opinion on any repair quote. Most competitors charge or refuse. Weekday mornings, repair customers welcome. Call 405-375-4822.

Why folks in Piedmont call me
I run my routes out of Kingfisher, and Piedmont is a regular stop. Most of my Piedmont customers found me by referral. I keep my truck stocked with the parts that fail most often in Oklahoma weather, so when I roll up I usually have what I need to fix the system the same day.
I quote everything in writing before the work starts. No “you need this” pressure, no equipment swaps you did not ask for. Just diagnosis, fix, written invoice. Call 405-375-4822 or book online at hartzellsheatair.com.
Common questions from Piedmont (73078)
How much does an AC repair cost in Piedmont?
A residential service call is $210 flat: $99 dispatch plus $111 diagnostic. The $111 diagnostic is not credited toward the repair. If I leave a written repair estimate and you accept it within 10 days, I give the $99 dispatch fee back. Most Piedmont repairs land between $200 and $850 all-in. Refrigerant work, blower motor failures, and capacitor swaps are the most common categories I see in this ZIP.
Do you offer same-day service in Piedmont?
Most days yes. If you call before noon and the job is straightforward (no-cool, no-heat, leak), I can usually be at your house in Piedmont that same afternoon. Heavy install days or extreme-weather backlog can push it to next-day, but I always tell you up front when you call.
What does a new HVAC install in Piedmont run?
A complete 3-ton air-source heat pump installed (heat pump + air handler + thermostat + permits) runs about $10,000 to $14,000 in Piedmont, depending on equipment tier and ductwork condition. OG&E rebates up to $3,000 stack on top. Geothermal is a different conversation, that is $25,000 to $36,000 range before rebates. I write a free estimate either way.
Do you service all brands in Piedmont?
Yes. Master HVAC license, NATE certified, 47 years on tools. I install Trane, Mitsubishi, Amana, ClimateMaster (geo), RunTru. I service whatever brand is sitting on your slab. If it has a refrigerant cycle and ductwork, I can work on it.
