Dual Fuel System Repair FAQ
Everything Charlotte homeowners need to know about dual fuel system repair
How much does dual fuel system repair cost in Charlotte?
Dual fuel repairs vary by which component needs work. Heat pump repairs: $200-$1,200. Furnace repairs: $200-$900. Switchover control issues: $150-$400. We charge $89 diagnostic (waived with repair) and diagnose both systems to ensure proper operation.
Why isn't my dual fuel system switching to the furnace?
Common causes: thermostat not set for dual fuel mode, faulty switchover relay, incorrect switchover temperature setting, or furnace issue preventing operation. We test both systems and controls to identify why switchover isn't happening.
Why is my furnace running when it's mild outside?
Possible causes: switchover temperature set too high, heat pump not working properly (so thermostat calls for backup heat), or thermostat settings incorrect. Running the furnace when the heat pump should handle it wastes money. We diagnose and fix this.
Can you repair both the heat pump and furnace?
Absolutely! Dual fuel repair requires expertise in both systems—we have it. We're licensed for heat pump refrigerant work and gas furnace service. One company, one diagnostic, comprehensive repair.
Why is my dual fuel running the heat pump below 30°F?
Thermostat switchover may be set incorrectly, or the outdoor temperature sensor may be faulty. Running the heat pump in very cold weather is inefficient and can cause freeze-ups. We adjust settings and test sensors.
What if my heat pump fails in winter?
That's the beauty of dual fuel—your gas furnace takes over! If your heat pump stops working, switch the thermostat to "emergency heat" to use furnace only until we repair the heat pump. You won't lose heat.
Why does "auxiliary heat" show on my thermostat constantly?
Auxiliary heat (gas furnace in dual fuel) should only run during cold snaps. Constant aux heat indicates: heat pump not working, switchover set wrong, or thermostat issues. This wastes money—the furnace costs more to run than the heat pump in mild weather.
Do you service all dual fuel brands?
Yes! We service Carrier, Trane, Lennox, Rheem, Goodman, and all major brands. Our technicians understand both heat pump and furnace components, plus the dual fuel controls that manage switchover.
How do I know which system needs repair in dual fuel?
Symptoms help identify: Heat pump issues show in cooling mode and mild-weather heating. Furnace issues appear only during cold snaps. Switchover problems cause wrong system running at wrong temps. Our diagnostic tests everything.
Can improper dual fuel settings waste money?
Definitely! Wrong switchover temperature can run the furnace when the heat pump is more efficient (costing more) or run the heat pump when it's too cold (straining the system). We optimize settings for Charlotte's climate and current energy rates.
How quickly can you repair dual fuel systems?
Most repairs take 1-3 hours. We diagnose both systems in one visit since dual fuel issues can involve either component. Complex repairs involving both systems may take 4-6 hours but we complete everything in one day when possible.
Should I repair or replace my dual fuel system?
If one component (heat pump or furnace) needs major repair and is over 10 years old, consider replacing that component. If both are aging, full system replacement may be best. We provide honest recommendations for your specific situation.
Do you handle gas furnace safety checks in dual fuel?
Absolutely! Every furnace service includes carbon monoxide testing and heat exchanger inspection. Safety is non-negotiable. Your dual fuel furnace may run less than a traditional furnace, but it still needs annual safety checks.
What warranty do you provide on dual fuel repairs?
We provide a 1-year parts and labor warranty on all dual fuel repairs, covering both heat pump and furnace components. We stand behind our work on both systems.
Why choose Kodiak for dual fuel repair?
Dual fuel requires expertise in heat pumps, gas furnaces, AND the controls that integrate them. We have all three. Many companies only know one or the other. As a family-owned company, we provide honest diagnosis and repair what actually needs fixing.
