Air-Source Heat Pump Repair in Oklahoma

We 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 mode — usually a failed reversing valve, refrigerant leak, or system stuck in cool mode
  • Outdoor unit iced over and not defrosting — normal during freezing rain, but a stuck defrost board or failed defrost sensor means it won’t clear itself
  • Backup heat running constantly — indicates 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 running — refrigerant charge loss, compressor failure, or reversing valve stuck in cooling position
  • Short cycling — low 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 we 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.

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 We 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.

Gas Furnace — Safety First

  • 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
Airflow & Distribution

  • 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
Electrical & Controls

  • 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, we 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 we’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.


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. We 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. We test ignition, flame signal, pressure switches, elements, sequencers, and safeties per model requirements.

Can you check carbon monoxide levels?

Yes, we 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. We provide an upfront price after diagnosis so you can choose the path that fits your home and budget.
