How Much Does Furnace Cleaning Cost? [2026 Data]

In 2026, the national average furnace cleaning cost is $150, though most homeowners pay between $70 and $400 depending on furnace type, system size, and where the unit is located in the home. Advanced cleaning packages and hard-to-reach installations, such as attic or crawlspace units, can push your total higher.

Furnace Cleaning Cost Breakdown: What Affects the Price?

Furnace cleaning costs range from $60 to over $400, with your furnace type, size, and location being the primary drivers of where your total lands. A small home with an electric furnace in good condition may start at around $60, while larger gas or oil systems cost more to service. Costs vary by furnace type, size, condition, and location, as the breakdown below shows.

Furnace Type

Your furnace type is one of the biggest factors in cleaning cost, with the average range spanning $60 to $400 across common furnace types. Electric furnaces sit at the lower end of that range, while gas and oil units cost more to clean due to their more complex system designs. Costs vary by furnace type, as shown below.

Size

Homes larger than the median 2,300 square feet, according to the U.S. Census Bureau, can expect to spend over $150 for a furnace cleaning, since a larger system requires more time to service. Smaller homes with compact systems will generally fall toward the lower end of the overall price range.

Condition

A standard furnace cleaning costs about $60 to $150, but if it has been a long time since your last service, expect to pay $150 to $400 for an advanced cleaning package. Even homeowners who keep up with regular cleanings will occasionally need a deeper clean to keep the furnace in top shape inside and out.

Time of Year

Scheduling a furnace cleaning in fall or winter means competing with high demand, which drives up both wait times and prices. Booking earlier in the year can help you save, though having a pro clean and inspect the furnace shortly before heating season is best for overall efficiency.

Furnace Location

Furnaces in hard-to-reach spaces cost more to clean, with an attic furnace or a unit tucked into a cramped crawlspace typically running $150 or more for the service. The harder it is for a pro to access the unit and all of its components, the more labor time the job requires.

Labor

Most pros charge for furnace cleaning on a project basis, but some companies bill by the hour at around $50 to $150 per hour. Since the job typically takes two to three hours to complete, an hourly rate can help you estimate your total before committing to a quote.

Additional Costs to Consider

Beyond the base cleaning fee, a few additional costs can come up when you schedule furnace service, from routine filter swaps to a full inspection alongside the cleaning.

Filter Replacement

Changing furnace filters at least once every 90 days is a DIY-friendly task that costs about $1 to $35, depending on the filter type your system requires. Never run your furnace without a filter, as doing so causes unnecessary wear and tear on the system.

Repairs

A furnace cleaning sometimes reveals wear or damage that needs attention, and furnace repairs cost about $130 to $500 on average. Depending on the furnace type and the extent of the damage, repair costs can range from $65 to over $1,400.

Inspection

A furnace inspection costs about $80 to $100 on average and may include light cleaning, but for a thorough clean you should schedule both services together. Combining an inspection with a full furnace cleaning brings your total to about $110 to $600.
