Curious how much it costs to service a furnace? For most U.S. homes, a standard furnace tune-up runs $100–$200, with a typical range of $80–$250. Oil furnace service often costs more—about $150–$300—because it includes extra cleaning parts. Emergency or after-hours visits can push totals above $250–$400+. This guide explains the true cost to service a furnace, what technicians actually do, how location and fuel type change the price, and smart ways to save without cutting corners on safety or comfort.
How Much Does It Cost To Service A Furnace?
The average U.S. homeowner pays $100–$200 for a routine furnace service (often called a “tune-up”). Budget providers may advertise specials as low as $69–$99, while premium, longer checkups can exceed $200–$250. The biggest drivers are fuel type, local labor rates, and whether any parts or deep cleaning are needed.
Expect a separate service call fee of $75–$150 in some markets, which may be waived if repairs are completed. After-hours, holiday, or emergency dispatch typically adds 1.5x–2x the normal labor rate, pushing a simple visit to $250–$400+.
Many HVAC companies offer combined heating and cooling maintenance packages. A two-visit plan (furnace in fall, AC in spring) often costs $180–$350 total and can include priority scheduling and small repair discounts.
What A Furnace Tune-Up Includes
Good furnace maintenance is more than a quick vacuum. A thorough service improves safety, efficiency, and reliability. While checklists vary, most visits take 45–90 minutes and include the following.
For Gas Furnaces (Natural Gas Or Propane)
- Inspect and clean burners, flame sensor, and igniter
- Check heat exchanger for cracks or corrosion
- Test safety controls, pressure switches, and limit switches
- Verify ignition sequence and flame rectification
- Measure gas pressure and combustion; adjust if needed
- Clean or replace filter (filter cost is usually separate)
- Check blower motor, wheel, and belt (if belt-driven)
- Inspect flue and venting; verify draft and condensate drainage on high-efficiency units
- Measure temperature rise and static pressure
- Test carbon monoxide at the supply plenum and ambient air
For Oil Furnaces
- Replace nozzle, oil filter, and pump strainer (often included in the price)
- Clean combustion chamber and heat exchanger surfaces
- Adjust electrodes and check ignition transformer
- Perform combustion analysis and tune for proper draft and stack temperature
- Inspect venting and barometric damper; check for soot
For Electric Furnaces
- Inspect and test heating elements and sequencers
- Check blower motor amperage and controls
- Verify electrical connections and tighten lugs
- Clean blower and cabinet; assess filter and airflow
Tip: Ask for a checklist or digital report. Good documentation helps with warranty claims and tracks efficiency from season to season.

Homeowners who reliably schedule one-off tune-ups and rarely need repairs may find pay-as-you-go cheaper. However, plans can improve reliability and make budgeting predictable, which is valuable for rental properties and households that want to minimize downtime.
Quick Payback Example
If a plan costs $250 and includes two tune-ups that would otherwise cost $180, the incremental $70 can be offset by a single $200 igniter repair with a 10% discount. Add priority service during cold snaps and the plan’s convenience may be worth it.
How Often To Service A Furnace
- Gas/Propane Furnaces: Once per year, ideally in late summer or early fall.
- Oil Furnaces: Once per year; includes nozzle, filter, and soot removal.
- Electric Furnaces: Annually to check elements, airflow, and safety controls.
Filter changes are more frequent: every 1–3 months for 1-inch filters, and every 6–12 months for 4–5 inch media, depending on dust, pets, and allergies. Many “no-heat” calls are solved by restoring airflow with a clean filter.
Energy, Comfort, And Safety Benefits
Well-maintained furnaces can run 5–15% more efficiently, depending on starting condition. Cleaning burners and verifying proper gas pressure supports clean combustion, which reduces soot and carbon monoxide risk. A tune-up is also an opportunity to catch hairline cracks in the heat exchanger, blocked flues, or failing motors before winter peaks.
Long term, maintenance protects warranties and extends equipment life—especially ECM blower motors and inducer assemblies, which are sensitive to poor airflow and dirt buildup.

When Bundling Services Makes Sense
Combining a furnace tune-up with air conditioner maintenance is common and can save $30–$80 compared to separate visits. If you have accessories—humidifier, UV light, ERV/HRV—ask about package pricing so the tech handles everything in one trip.
What A “Deep Clean” Might Add
Some older or neglected furnaces need more than a standard tune-up. Extra tasks can include blower wheel removal and balancing, secondary heat exchanger flushing (for condensing models), or extensive soot removal on oil systems. Expect an additional $60–$250 depending on time and materials.
How The Cost To Service A Furnace Compares To Skipping It
Skipping maintenance can lead to clogged filters, overheated heat exchangers, and premature motor failures. Even one avoided emergency call—often $250–$400+ with after-hours rates—can justify routine furnace service. For oil furnaces, skipping annual cleaning risks heavy soot buildup that reduces efficiency and increases smoke and odor.
