Air-Source Heat Pump Repair in Oklahoma
I provide repair and diagnostic service for air-source heat pump systems throughout central Oklahoma. Heat pumps have specific failure modes that differ from gas furnaces, and Oklahoma winters create conditions that stress heat pump components in predictable ways.
Common heat pump symptoms in Oklahoma winters:
- System blowing cold air in heat modeusually a failed reversing valve, refrigerant leak, or system stuck in cool mode
- Outdoor unit iced over and not defrostingnormal during freezing rain, but a stuck defrost board or failed defrost sensor means it won’t clear itself
- Backup heat running constantlyindicates the heat pump is undersized for the load, has a refrigerant issue, or the auxiliary heat is taking over prematurely
- No heating output despite the system runningrefrigerant charge loss, compressor failure, or reversing valve stuck in cooling position
- Short cyclinglow charge, high pressure lockout, or a bad thermostat causing rapid on/off
Reversing valve failure:
The reversing valve switches the heat pump between heating and cooling mode. When it fails or sticks, the system either blows cold air in winter or won’t cool in summer. A stuck reversing valve is one of the trickier heat pump diagnoses, it requires checking both the solenoid coil and the valve body. Replacement typically runs $600-$1,500 installed, but I diagnose it precisely before recommending the repair.
Geothermal heat pump repair, how it differs:
Geothermal heat pumps share some components with air-source units (compressor, reversing valve, refrigerant circuit) but the ground loop introduces unique failure points: loop pump failures, antifreeze concentration issues, flow restrictions, and pressure loss in the loop field. As an IGSHPA-Accredited geothermal contractor, Hartzell’s can diagnose and service both the mechanical unit and the ground loop system, most HVAC companies can’t.

Repair or Replace Your Heating System?

Pricing: $99 dispatch fee for the service call. $111 diagnostic fee for repair visits, applied toward the repair when you approve the work same day. Free estimates on any new system install. For a clear breakdown, see $99 dispatch and $111 diagnostic pricing on every service call.

Common Heating Repair Costs in Oklahoma
Ranges shown are typical installed costs. Exact pricing depends on equipment age, access, and parts availability. Hartzell’s provides upfront pricing before any work begins.
| Repair | Typical Range | Notes |
|---|---|---|
| Ignitor replacement | $175-$350 | Hot surface ignitors wear out every 5-7 years; very common furnace repair |
| Pressure switch replacement | $150-$300 | Monitors draft inducer; can fail or get stuck in humid conditions |
| Draft inducer motor | $400-$750 | Vents combustion gases; failure causes pressure switch lockout |
| Gas valve replacement | $350-$700 | Controls gas flow to burners; verified with manometer before and after |
| Control board replacement | $450-$950 | The “brain” of the furnace; diagnosed carefully before replacing |
| Blower motor replacement | $450-$850 | ECM variable-speed motors cost more than standard PSC motors |
| Heat exchanger inspection | $111 diagnostic | Cracked heat exchangers are a CO risk; camera inspection available |
| Reversing valve (heat pump) | $600-$1,500 | Common heat pump failure; switches between heat and cool mode |
| Defrost board (heat pump) | $350-$800 | Controls outdoor coil defrost cycle; failure causes ice buildup |

What I Check on a Heating Diagnostic Visit
A heating call is different from an AC call, gas systems have safety components that have to be checked in sequence before I touch anything else. Here’s exactly what gets inspected before I give you a quote.
- Heat exchanger, cracks or breach (CO risk)
- Flue pipe and venting, blockage, backdraft
- Gas valve operation and pressure
- Igniter and flame sensor, most common failure points
- Limit switch and rollout switch, tripped or failed
- Blower motor, amps, speed, and CFM
- Filter and return air restriction
- Supply vs. return temperature rise
- Duct leakage, obvious disconnects or tears
- Static pressure, undersized or blocked ductwork
- Control board, error codes, relay function
- Inducer motor, pre-purge operation and pressure switch
- Capacitor (heat pump or AC-integrated systems)
- Thermostat wiring, heat call sequence
- Condensate drain (high-efficiency furnaces)
Three outcomes, explained upfront: After the diagnostic I’ll put you in one of three categories, straightforward repair (igniter, sensor, board, same-day fix), monitored operation (system is working but aging, I discuss timeline before next winter), or replacement makes more sense (cracked heat exchanger, failed inducer, system over 15 years with multiple issues). I’ll tell you what I’d do if it were my house, no pressure either way.
Common Heating Repairs, What to Expect
Real-world ranges from jobs I’ve run in Kingfisher County and surrounding areas. The $111 diagnostic is credited toward your repair if you approve within 14 days.
| Repair | Typical Range | Notes |
|---|---|---|
| Igniter replacement | $150, $275 | #1 no-heat call in Oklahoma, 30-min job |
| Flame sensor cleaning/replacement | $125, $225 | Furnace lights then shuts off, classic symptom |
| Pressure switch replacement | $175, $325 | Inducer-related, check venting first |
| Control board replacement | $400, $900 | Weigh against system age, boards are expensive |
| Inducer motor replacement | $450, $850 | High-efficiency furnaces, noisy startup is a warning sign |
| Blower motor replacement | $450, $750 | Variable speed motors run higher |
| Gas valve replacement | $350, $650 | Confirmed with pressure test before replacing |
| Heat exchanger, cracked | Replacement recommended | CO risk, repair not practical, replacement is the call |
Ranges include parts and labor. Actual cost depends on equipment brand, part availability, and access. Final quote given before any work starts.
Blower motor giving out? It might be time for an ECM upgrade.
Most of the repair calls I run end up at the blower motor sooner or later. The old PSC motors burn out, run hot, and waste electricity. When yours fails, you can swap it for the same PSC part, or step up to an Azure ECM variable-speed motor that runs quieter, uses 60 to 75 percent less power, and lasts longer. I lay out the real numbers, side by side, on my ECM upgrade page.
- OEM PSC replacement: $1,912
- Standard PSC blower motor: $2,187
- Azure ECM variable-speed upgrade: $2,304 to $2,438
Frequently Asked Questions
My furnace blows cold air, what now?
Check the filter and thermostat mode first. If those look fine, safety controls may be tripping. I run combustion and airflow checks to locate the fault.
Is it safe to run the heater with a burning smell?
Dust burn-off early in the season can be normal. If the smell is strong, smoky, or steady, turn it off and call (405) 375-4822 for a safety check.
Do you service gas and electric furnaces?
Yes. I test ignition, flame signal, pressure switches, elements, sequencers, and safeties per model requirements.
Can you check carbon monoxide levels?
Yes, I carry CO instruments and inspect the heat exchanger and venting to confirm safe operation.
What does a typical repair cost?
Costs vary by part and labor. I provide an upfront price after diagnosis so you can choose the path that fits your home and budget.

2026 Repair Upgrades I Offer (Honest Pricing)
Most shops pad bills around new refrigerants and motor upgrades. I will not. Here is what is real on a typical AC repair call in 2026:
- R-454B and R-32 refrigerants are now standard on new equipment. Both are mildly flammable A2L refrigerants, both cost more per pound than R-410A, and both require certified handling. I stock both. R-454B recovery $445, R-32 recovery $395. Customers should hear this from me before they hear it from a competitor padding a bill.
- Blower motor upgrade ladder. PSC 1/3 HP installed runs $2,187 (115V) or $2,230 (230V). Azure ECM variable-speed runs $2,304 to $2,438. About $250 more for a quieter motor and 30%+ fan energy savings. Worth it on a long-haul system.
- Hard Start Kit upgrade $415 installed. Cheap insurance on a compressor that already worked too hard. High attach on any compressor service call.
- BEST surge protection bundle $1,225 installed. Control board spike protection plus transformer replacement plus in-line fuse. One $1,225 fix beats one $3,195 compressor replacement after the next Oklahoma lightning storm.
- Whole-home dehumidifier $2,895 (90 pint+). Premium IAQ tier on top of the $2,295 70-pint unit. Often added when the evaporator or blower is already open.
Call 405-375-4822 and I will tell you the truth about your system before quoting any of these.
