How Much Does Furnace Cleaning Cost? [2024 Data]
Normal range: $70 - $400
Furnace cleaning costs $150 on average, but you could pay anywhere between $60 and $1,000, depending on the type and size of the furnace.
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.
| Type | Cost |
|---|---|
| Electric | $60–$150 |
| Gas | $60–$175 |
| Oil | $100–$1,000 |
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
"As a professional, I'd never miss out on routine servicing for my heating system. It's really easy to skip servicing your unit, but it can lead to breakdowns and high energy bills. It can be a safety issue, too."
— Yashar Mosaferi, President of Klondike AC, British Columbia, Canada
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.
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.
Cost to Clean a Furnace Yourself
Aside from swapping out furnace filters every few months, you shouldn’t attempt to clean a furnace yourself. This is a dangerous job because making a mistake or damaging the furnace during the cleaning could lead to electric shocks and/or gas leaks. Performing a cleaning without a licensed professional could also void your furnace warranty.
You can handle filter replacements on your own, which will cost you about $1 to $35 per filter. Change filters at least once every three months.
DIY vs. Hiring a Furnace Cleaning Pro
Most of the cost of cleaning a furnace is the labor, but hiring a local furnace cleaner is a worthwhile investment. The pros can thoroughly clean your furnace system and even spot potential problems before they become costly and inconvenient damages. This ensures your furnace is working efficiently and safely, and over time, this can save you money on heating bills and repairs.
Cost of Common Furnace Cleaning Add-Ons
After your furnace cleaning, you may consider some additional home improvement projects to give your furnace an efficiency boost or make your rooms even warmer ahead of the cold months. Some common furnace projects you may consider include:
Oil tank replacement cost: $800–$3,800
New furnace cost: $2,815–$6,810
Air duct cleaning cost: $270–$500
Boiler installation cost: $600–$12,000
Heat pump cost: $4,195–$7,620
Radiant floor heating cost: $1,700–$6,000
