Mini-split warranty repair in Edmond, OK
May 2026
A new ductless mini-split in Edmond was leaking water and not working. My tech traced it to a hose that had come loose at the condensate pump and reconnected it. I handled it as a warranty call.


AC condenser and coil replacement in Kingfisher, OK
May 2026
This cooling system in Kingfisher needed a new condenser and a matching indoor coil. The condenser sits on the roof, so my crew brought in a crane to set the new one, then flushed the system before starting it up.
Mini-split leak test in Kingfisher, OK
May 2026
A mini-split in Kingfisher had stopped working, and the homeowner thought it had frozen up. A frozen coil often points to a refrigerant leak, so my tech pressurized the whole system with nitrogen, high side and low side, to see whether it would hold before anything got recharged.

Blower motor replacement in Kingfisher, OK
May 2026
The AC in this Kingfisher home had stopped working. My tech diagnosed a failed indoor blower motor and replaced it.


Frozen coil service in Dover, OK
May 2026
This package unit in Dover wasn't running. My tech found the evaporator coil frozen and thawed it out. The ductwork needs another return to keep it from freezing again, so adding that return is the next step.

AC repair in Edmond, OK
May 2026
An Edmond homeowner booked this AC call online. My tech replaced a capacitor and flushed the condensate drain line on the same visit.



New HVAC system and ductwork in Watonga, OK
May 2026
This Watonga home got a complete new system: a gas furnace and air conditioner, plus all new ductwork, supply and return.


AC electrical repair in Kingfisher, OK
May 2026
This Kingfisher system needed two electrical parts in the outdoor unit: a new run capacitor and a new contactor, the switch that starts the compressor and fan. My tech also found a dirty filter at the return grille.


Gas water heater replacement in Enid, OK
May 2026
The hot water tank at this Enid home had quit. I had the new gas water heater delivered to my shop first, then my tech pulled the old tank and installed the new one, with the gas line and vent hooked up.

New AC condenser and coil in Kingfisher, OK
May 2026
This Kingfisher home needed its cooling side replaced, not the whole system. My crew installed a new condenser and indoor coil and flushed the existing refrigerant lines.


Condenser fan motor replacement in Hennessey, OK
April 2026
An air conditioner in Hennessey had stopped working. My tech found the outdoor fan motor had failed and replaced the motor and fan blade together as a matched set.
Walk-in cooler diagnostic in Oklahoma City, OK
April 2026
A walk-in cooler at an Oklahoma City business had stopped working. My tech checked it from the evaporator inside the box to the condensing unit that sits on top of it, to track down what failed.



Air scrubber hookup in Okarche, OK
April 2026
During a maintenance visit in Okarche, the homeowner wanted an air scrubber they already owned hooked up to their system. My tech wired it in, set it up and tested it, and replaced a capacitor on the same visit.

New AC and gas furnace in Kingfisher, OK
April 2026
The homeowner called about the blower on the attic furnace in this Kingfisher home, then decided to replace the system. My crew installed a new air conditioner and gas furnace, with the furnace set in the attic.


AC tune-up in Kingfisher, OK
April 2026
This Kingfisher system hadn't been tuned up in a while, and the outdoor coil showed it, packed with dirt. My tech cleaned the coil and went through the rest of the tune-up list: refrigerant, capacitor, contactor and drain.


New AC and furnace install in Kingfisher, OK
April 2026
My crew installed a new air conditioner and gas furnace in this Kingfisher home. The equipment order showed up without a drain pan, so my tech picked one up before starting, and the install includes a float switch, a safety meant to shut the system off if the condensate drain backs up.


Outdoor fan motor repair in Watonga, OK
April 2026
This older system in Watonga was built for R-22, which isn't made anymore. My tech replaced the outdoor fan motor and a capacitor, and topped off the charge with R-438A, a replacement refrigerant made for R-22 systems.

Questions About This Map
What towns does Hartzell's Heat & Air work in around Kingfisher, Oklahoma?
My trucks run every week across seven counties: Kingfisher, Canadian, Oklahoma, Garfield, Major, Logan and Blaine. The towns with the most completed jobs in my records are Kingfisher (3,500+), Okarche (650+), Hennessey (350+) and Watonga (300+). The table above lists every town where I have enough jobs to show a count.
Are these real Hartzell's jobs or stock examples?
They are real. Every pin comes from a completed job in my own records, and each write-up above uses the notes and photos my crew made on that visit. A job only goes on this page after it passes a privacy review.
Why does the map show the town instead of the house?
Your home is your business. Each pin sits on the center of its town, so nobody can use this page to find a customer's house. I never publish a name, a street or a house number here.
How can I see HVAC jobs near me in Central Oklahoma?
Type your ZIP code or town in the search box above the map and press Show Work Near Me. The map zooms to your area so you can see the work around you. Check Has Photo beside the map to see only the jobs with pictures.
Do you install geothermal outside the Kingfisher area?
Yes. For geothermal I travel across almost the entire state of Oklahoma, depending on the customer and the project, and the Lake Texoma area job in the case studies above is one of those trips. I am IGSHPA accredited for geothermal.
Do you do regular heating and cooling service outside those seven counties?
My everyday service trucks stay in the seven counties above so I can get to you quickly. The other towns in the "also worked in" list are past jobs, not a promise of regular service there. If you live outside the seven counties, call the office and I will tell you straight what I can do.
Need HVAC help in your neighborhood?
