Dave Hartzell spent five years as a volunteer firefighter with the Watonga VFD. What he learned there still shapes how Hartzell’s runs today: the person who responds when things fail is the same person who believes most strongly in preventing them. Regular HVAC maintenance isn’t a revenue tool. It’s the most effective thing you can do to keep your equipment running through a central Oklahoma summer, and avoid the emergency call at 2 a.m. in January.

What’s Included in a Hartzell’s Tune-Up
Full System Inspection
Visual inspection of all accessible components, inside and outside the unit. I look at things most technicians skip because they’re not on a checkmark sheet.
Coil Cleaning
Dirty evaporator and condenser coils are one of the most common causes of efficiency loss and compressor failure in Oklahoma summers.
Electrical Check
Capacitors, contactors, wiring, and amp draws on all motors. A failing capacitor costs $80-$150 to replace. A compressor that runs on a dying capacitor costs $1,200+.
Refrigerant Level Check
Low refrigerant causes compressor strain and poor cooling. I check charge and look for signs of leaks at every maintenance visit.
Thermostat Calibration
A miscalibrated thermostat wastes energy. I verify it’s reading accurately and cycling correctly at each setpoint.
Heat Exchanger Inspection
A cracked heat exchanger can allow combustion gases into your home. I inspect on every furnace service. This is a safety check, not optional.
Blower & Airflow Check
Restricted airflow from a dirty blower or clogged filter causes comfort problems and adds stress to the compressor over time.
Written Report
You get an honest written assessment of your system’s condition. Not a verbal impression, not a sales pitch, a document you can use to make decisions.
All labor performed during your maintenance visit is backed by Hartzell’s 6-month labor guarantee. If something I service fails within six months, I come back.
Why Oklahoma’s Climate Makes Maintenance More Critical
Central Oklahoma is rough on HVAC equipment. The temperature extremes, 100°F+ summers and occasional below-zero winters, mean your system runs longer hours under greater stress than systems in milder climates. Customers in Kingfisher, Watonga, Hennessey, Cashion, and Crescent all face the same conditions: Oklahoma heat, Oklahoma dust, Oklahoma wind. Different county lines, same equipment wear.
The numbers on maintenance vs. repair:
- A capacitor failure caught in a spring tune-up: $80-$150
- That same capacitor failing on a 105°F July afternoon and burning out the compressor: $1,200-$2,500
- A $229 annual tune-up vs. an emergency call premium on the hottest day of the year: maintenance wins every time

Common Questions About HVAC Maintenance
How much does an HVAC tune-up cost in Kingfisher, Oklahoma?
Hartzell’s charges $229 for a full HVAC tune-up in Kingfisher, Oklahoma.
The $229 covers a 21-point inspection, coil cleaning, electrical tests, refrigerant level check, and a written report on your system’s condition. Dave’s 360 Plan members receive discounts. This is not a 15-minute checkmark sheet, I actually inspect, clean, and measure every item. Call 405-375-4822 to schedule.
How often should I have my HVAC system serviced in Oklahoma?
Oklahoma homes should have HVAC service once a year, spring for AC, fall for heat or heat pump.
Oklahoma’s climate is hard on equipment: 100°F+ summers, cold winters, and wind-driven dust that clogs coils faster than in milder states. Schedule AC service in spring (March, April) before the heat arrives; furnace or heat pump service in fall (September, October) before winter. Scheduling during shoulder seasons means shorter wait times and no peak-season premium.
What’s included in a Hartzell’s HVAC tune-up?
Hartzell’s tune-up includes inspection, coil cleaning, electrical checks, refrigerant check, and a written report.
Specifically: filter check, evaporator and condenser coil cleaning, capacitor and contactor testing, amp draws on all motors, refrigerant level verification, thermostat calibration, blower motor inspection, heat exchanger inspection (furnaces), safety control testing, and a written assessment you keep. You leave with documentation, not a verbal impression.
Does my warranty require annual HVAC maintenance?
Yes, most major HVAC brands require documented annual maintenance to keep their parts warranty valid.
Trane, Mitsubishi, Carrier, Daikin, and American Standard all have warranty language requiring documented annual service. If a major component fails and you cannot show records, the manufacturer can deny the claim. Hartzell’s provides written documentation of every visit, dated, itemized, and signed.
My HVAC system seems to be running fine, do I really need a tune-up?
Yes, most HVAC failures give no visible warning before they fail at the worst possible moment.
A capacitor reading at 40% capacity looks fine from the outside but will fail on the hottest afternoon in July. A heat exchanger crack is invisible without inspection but can allow combustion gases into your home. “Running fine” and “safe and efficient” are two different things. Dave has 45 years of HVAC experience, he finds what others miss because he actually looks.
How long does an HVAC tune-up take?
A thorough HVAC tune-up at Hartzell’s takes 45 minutes to one and a half hours.
I do not rush. If your system is clean and the components test well, it is on the shorter end. If something needs attention, I explain what it is and what it costs before touching anything. You will not be surprised by an invoice at the end of the visit.
Considering a system upgrade? If repair costs are adding up or your equipment is aging, see my HVAC System Replacement page for honest guidance on when replacement makes sense.
Seasonal maintenance offers. Ask about my Spring HVAC Tune-Up before cooling season, and check the $27 PMA starter plan if you want low-cost annual coverage.
Two visits per year covers heating and cooling season.
