Furnace tune-up cost is typically $70 to $300, according to Fixr, while HomeGuide puts an annual tune-up at $70 to $200 or more. A yearly maintenance plan, meanwhile, runs about $150 to $500 and often includes the tune-up plus repair discounts. The Consumer Product Safety Commission recommends a professional inspection of fuel-burning heating systems every year, and many manufacturers require annual maintenance to keep the warranty valid.
Below, you’ll find furnace tune-up cost by service type, what a proper tune-up should include, a simple annual checklist and how to tell whether a maintenance plan is worth it. Information checked on November 4, 2026.
Furnace tune-up cost at a glance
| Service | Typical cost | Source |
|---|---|---|
| Furnace tune-up | $70–$300 | Fixr (Jan. 30, 2026) |
| Furnace tune-up | $70–$200+ | HomeGuide (Dec. 31, 2025) |
| Gas furnace routine maintenance | $80–$170 a year | Carrier (Oct. 13, 2026) |
| HVAC maintenance contract | $150–$500 a year | Fixr (Jan. 30, 2026) |
| Service call (diagnosis and minor repairs) | $70–$200 | Fixr (Jan. 30, 2026) |
| Furnace plus AC (split system) maintenance | $200–$600 | Fixr (Jan. 30, 2026) |
Furnaces cost more to service than a central AC, Fixr explains, because a unit that burns fuel has more components to check for safety and usually needs more cleaning.
What a furnace tune-up should include
ENERGY STAR’s maintenance checklist is a good benchmark. In general, a technician should:
- Check the thermostat settings and the system’s controls, including the starting cycle.
- Tighten electrical connections and measure voltage and current on the motors.
- Lubricate moving parts to reduce friction and electricity use.
- Check gas or oil connections, gas pressure and burner combustion.
- Inspect the heat exchanger, since a cracked one makes the furnace less safe.
- Clean and adjust the blower, because airflow problems can reduce efficiency by up to 15%.
- Inspect the condensate drain on high-efficiency furnaces.
- Also check the chimney and flue, as CPSC recommends.
Annual furnace maintenance checklist
| When | Task | Who |
|---|---|---|
| Every month in heating season | Inspect, clean or change the air filter | You |
| Every month | Test carbon monoxide alarms | You |
| Once a year | Replace CO alarm batteries, unless they have sealed 10-year batteries | You |
| Every fall | Professional furnace tune-up and safety inspection | HVAC technician |
| All year | Keep the area around the furnace and vents clear | You |
Is a furnace maintenance plan worth it?
Overall, a maintenance plan usually costs $150 to $500 a year. Some include the tune-up, while others only discount it; most also offer cheaper service calls, priority scheduling and lower emergency fees, Fixr says. HomeGuide, similarly, describes plans that include tune-ups, priority service and discounted repairs.
As a result, a plan tends to pay off for older systems that need regular repairs. For a newer furnace, on the other hand, a single annual tune-up is often enough, so compare the plan price with one tune-up plus a likely service call.
Why skipping maintenance costs more
- Higher bills: a dirty filter increases energy costs and can damage the equipment, leading to early failure, according to ENERGY STAR.
- Safety risks: HomeGuide says the most common cause of a cracked heat exchanger is overheating from a dirty filter, a lack of maintenance or an oversized furnace.
- Lost efficiency: for example, HomeGuide says an oil furnace’s efficiency can drop to 60% to 70% after 15 to 20 years without annual maintenance.
- Warranty: many manufacturers require yearly maintenance to keep coverage, HomeGuide notes.
When to schedule a furnace tune-up
ENERGY STAR recommends checking the heating system in the fall, because contractors get busy once winter arrives. In fact, it suggests timing check-ups around the clock changes in spring and fall so they’re easy to remember.
How to avoid upsells during a tune-up
Most technicians are honest, but a few use tune-ups to sell new equipment. For instance, HomeGuide warns about scams that make a heat exchanger appear cracked in order to sell a whole new furnace. Therefore, ask for photos and combustion test results before you agree to a major repair, and get a second opinion if the news is bad. Our guide to a cracked heat exchanger explains what to look for.

Furnace tune-up cost FAQ
How often should a furnace be serviced?
Once a year, because CPSC recommends annual professional inspections of all fuel-burning heating systems, and ENERGY STAR recommends a pre-season check-up each fall.
Does a heat pump need a tune-up too?
Yes, and more often. Fixr says heat pump maintenance costs $75 to $150 and is recommended twice a year, before the heating and cooling seasons.
Can I tune up my furnace myself?
You can and should handle the filter and CO alarm checks. However, gas pressure, combustion and heat exchanger checks are jobs for a trained technician.
