How Much Does Furnace Cleaning Cost? [2025 Data]

The average furnace cleaning cost is about $150, although prices often range from around $70 to $400, depending on the type of furnace, size of the furnace system, and where the furnace is located in your home. Additional factors, like how long it’s been since your last furnace cleaning and whether you opt for a basic or deep clean, can also influence the cost. 

Experts recommend you schedule a furnace cleaning at least once per year. That’s because dust and debris can quickly build up in the furnace. Not only does this mean your furnace has to work harder to warm your space, leading to higher heating bills, but it can also wear it down faster and cost you more in repairs.

Furnace Cleaning Cost Breakdown

Furnace cleaning costs range from $60 to over $400. Cleaning an electric furnace that’s in good condition and is in a small home may start at around $60 while cleaning a larger oil or gas furnace system tends to be more expensive. If your furnace is located in a hard-to-reach space, you’ll also pay more for any cleaning or repair services.

Furnace Type

Electric, gas, and oil are three common furnace types. Because of their more complex system designs, gas and oil furnaces tend to cost more to clean, while electric furnace cleaning costs fall on the lower end of the average $60 to $400 price range.

Size

The size of your home can influence the cost of cleaning the furnace because a larger system will require more time to service. According to the U.S. Census Bureau, the median home size is about 2,300 square feet. Homes larger than this can expect to spend over $150 for a furnace cleaning.

Condition

If it’s been a long time since you’ve last scheduled a furnace cleaning, you’ll need to pay extra for a deeper clean. While a standard furnace cleaning costs about $60 to $150, you’ll spend around $150 to $400 for an advanced cleaning package. Even if you keep up with regular cleanings, from time to time you’ll need to spend a little more for the deep clean to make sure your furnace is in tip-top shape, inside and out.

Time of Year

Looking to schedule a furnace cleaning a few weeks before winter hits? Prepare to get in line—and to pay a premium. Fall and winter are some of the busiest times of year for furnace professionals, as many people rush to make sure their furnaces will reliably heat their homes as the winter chill begins to set in. You may be able to save by scheduling an appointment earlier in the year, but having a pro inspect and clean the furnace shortly before you need it is best for furnace efficiency.

Furnace Location

The more difficult it is to access the furnace and all of its parts, the more you’ll need to pay for the cleaning service. If you have an attic furnace or your appliance is located in a cramped crawlspace, expect to spend $150 or more for the cleaning.

Labor

Typically, pros will charge for furnace cleaning services on a project basis, but you may also come across furnace cleaning companies that charge by the hour. In that case, you can expect to spend about $50 to $150 per hour, and this job takes about two to three hours to complete.

Additional Costs to Consider

From changing out a furnace filter every season to scheduling an inspection alongside your annual cleanings, there are additional costs you may encounter when you get your furnace cleaned.

Filter Replacement

Be sure to change furnace filters at least once every 90 days. This task is DIY-friendly and will cost about $1 to $35, depending on the type of filter your furnace requires. Remember not to run your furnace without a filter to avoid unnecessary wear and tear.

Repairs

During the cleaning, a furnace expert may notice wear and tear or damage that requires repairs. Furnace repairs cost about $130 to $500 on average, although the repairs may range from $65 to over $1,400, depending on the type of furnace and the extent of the damage.

Inspection

A furnace inspection costs about $80 to $100 on average. Inspections may include light cleaning services, but for a more thorough clean, you should consider scheduling both services. For an inspection and furnace cleaning, you’ll spend a total of about $110 to $600.
