FAQs
What are the most common signs that my vehicle’s heater needs repair?
Typical indicators include weak or no airflow from the vents when the heat is on, air that never warms up, a sweet smell inside the cabin (which can point to a leaking heater core), fogged-up windows that don’t clear, or coolant pooling under the vehicle. If you notice any of these issues, schedule a diagnostic so we can pinpoint the exact problem before it leads to engine-overheating or more expensive repairs.
Do you service every make and model in La Follette, including older or specialty vehicles?
Yes. Our ASE-certified technicians work on domestic, Asian, and European cars, trucks, SUVs, and commercial vans—both modern and classic. We maintain access to factory service data, OEM and high-quality aftermarket parts, and specialized tools required for hard-to-find heaters, dual-zone climate control units, and diesel cab heaters.
How long does a typical heating repair take?
A standard heater core flush or blend-door actuator replacement can be finished the same day, usually within 2–4 hours. More complex jobs, like a full heater core replacement that involves removing the dash, may require 4–8 labor hours and an overnight stay to let sealants cure and to run a pressure test before reassembly. We’ll give you a written time estimate before any work begins so you can plan transportation.
What price range should I expect for common heat repairs?
Costs vary with the part and labor involved: • Coolant flush and new thermostat: $120–$200 • Heater hose or valve replacement: $150–$300 • Blend-door actuator motor: $180–$350 • Heater core replacement: $600–$1,100 (due to dash removal) All prices include parts, labor, antifreeze top-off, and a post-repair system test. We’ll present a detailed quote up front and honor it—no surprise fees.
Can you inspect and repair my air-conditioning and heating system in the same appointment?
Absolutely. Because the heater and A/C share components such as the blower motor, cabin filters, and some control electronics, our comprehensive climate-control diagnostic covers both systems. If we find issues on the A/C side—low refrigerant, compressor problems, or clogged condensers—we can normally address them during the same visit, saving you time and a second trip.
Do your heating repairs come with a warranty or satisfaction guarantee?
Yes. All heater repairs include a 24-month/24,000-mile nationwide parts and labor warranty, honored at thousands of affiliated repair shops if you travel outside La Follette. In addition, we provide a complimentary re-inspection within 30 days to ensure the system is performing at factory specifications. Your satisfaction is fully backed by our no-hassle policy: if an issue recurs, bring the vehicle back and we’ll make it right at no additional cost.
