Hartzell’s Heat & Air | Best HVAC Company in Kingfisher Oklahoma

Who is the best HVAC company in Kingfisher Oklahoma?

I’m Dave Hartzell, owner and Master HVAC technician with 45 years on the tools. I’ve run Hartzell’s Heat & Air right here on South Main in Kingfisher for 15+ years. Here’s why I’m comfortable calling us the best HVAC company in Kingfisher, and it has nothing to do with what anybody else is doing. It comes down to credentials, training, factory recognition, and 279 public reviews.

My skills and license

I hold the Oklahoma Master HVAC license. That is the top tier the state issues. It means I tested through Mechanical Journeyman first, logged the hours, then passed Master. Not every shop in Kingfisher has a Master on staff. Most truck-based operators run on a Journeyman card or an apprentice working under somebody else’s license. When you call Hartzell’s, the person diagnosing your system is the person who signed for the license.

The 45-year career started when I was 18. Air-cooled chillers, residential split systems, geothermal loops, commercial rooftop units, R-22 retrofits to R-410A, now R-454B. I have torn apart and rebuilt every brand of equipment that has been sold in central Oklahoma since the early 1980s. That kind of pattern recognition is what diagnoses a hard-start cap going bad before it kills your compressor, or a refrigerant charge that is 4 oz off because the previous tech weighed in wrong.

Continuing training

HVAC code changes. Refrigerants change. Controls change. I keep certifications current instead of letting them lapse:

• NATE Certified. North American Technician Excellence. The industry-recognized competency exam. natex.org
• IGSHPA Accredited Installer. International Ground Source Heat Pump Association. Required for closed-loop geothermal work done right. igshpa.org
• EPA Section 608 Universal. Refrigerant handling for all system types.
• Manufacturer factory training. Mitsubishi, Trane, ClimateMaster, Amana, Goodman, Daikin. Updated every time a new product line drops.

Factory dealer awards

Manufacturers do not hand these out for showing up. Each one requires sales volume, technician training hours, warranty performance, and customer-satisfaction scores. Hartzell’s holds all five at once. I do not know of another shop in Kingfisher County that does.

• Mitsubishi Diamond Dealer. Top tier in Mitsubishi’s ductless mini-split program. Extended warranty coverage, factory tech support hotline, priority parts.
• Trane TCS SELECT (Trane Comfort Specialist). Highest dealer designation Trane offers. Customer-satisfaction scores have to stay above the cutoff or you lose it.
• ClimateMaster GeoElite. ClimateMaster’s premium geothermal dealer program. Required for the best loop warranties.
• Amana Brand Advantage Dealer. Amana’s dealer recognition tier with lifetime compressor coverage on qualifying equipment.
• BBB A+ Accredited (11 years). Better Business Bureau accreditation maintained every year since 2014. bbb.org

What you actually pay

I post my prices because if a shop will not tell you what something costs before they show up, that is your first answer about who they are.

• $99 dispatch fee. Every truck roll. Waived only on the included annual maintenance visit for PMA members.
• $111 diagnostic. Credited back to the repair if you accept it within 14 days.
• Free estimates on every new system install.
