Key Takeaways

  • The average cost of cleaning a furnace ranges from $50 to $300, depending on factors such as the type and condition of the furnace.
  • Additional costs to consider include air filter replacement, labor fees, accessibility of the furnace location, and potential discounts during off-peak seasons.

Factors Affecting Furnace Cleaning Cost

Several factors can affect the cost of cleaning a furnace, including the type and condition of the furnace, the need for air filter replacement, labor costs, accessibility to the furnace, seasonality factors, and any additional costs or considerations that may arise.

Furnace Type

The type of furnace you own can significantly impact the overall cost of cleaning. Gas furnaces usually have lower maintenance costs due to their simplicity and common usage, typically priced between $50 and $300 for a thorough cleaning.

Conversely, oil furnaces may demand higher fees because they require additional servicing steps like changing nozzles or adjusting electrodes, increasing the average cleaning cost to around $100.

Electric furnace maintenance might be similarly priced with gas units, but bear in mind that it’s all subject to the specific model’s design complexity and accessibility features.

Furnace Condition

The condition of your furnace can impact the cost of cleaning it. If your furnace is well-maintained and regularly serviced, the cleaning process may be simpler and less time-consuming, resulting in a lower cost.

However, if your furnace is dirty or has not been cleaned for a long time, it may require a deep cleaning to remove built-up dirt and debris. Deep cleaning typically costs more than basic maintenance cleaning.

To ensure you get an accurate estimate for the cost of cleaning your furnace, it’s important to provide detailed information about its current condition to the service provider.

Air Filter Replacement

Air filter replacement is an important factor to consider when calculating the cost of cleaning a furnace. The average cost for air filter replacement ranges from $10 to $30 per filter, depending on the type and quality.

It’s recommended to replace the air filters every 90 days or sooner if they become dirty or clogged. Regularly replacing your air filters not only improves indoor air quality but also helps maintain proper airflow, which can prolong the lifespan of your furnace and save on energy costs in the long run.

So, don’t overlook this affordable yet essential component of furnace maintenance.


Labor is one of the factors that can affect the cost of cleaning a furnace. Hiring professionals to clean your furnace typically incurs additional expenses. The average cost for labor ranges from $50 to $150, depending on the complexity and size of the job.

However, it’s important to remember that professional labor ensures thorough and efficient cleaning, ensuring that your furnace operates at its best and extends its lifespan. Additionally, hiring professionals saves you time and effort in performing the task yourself.


Accessibility is an important factor that can impact the cost of cleaning a furnace. If your furnace is in a location that is difficult to access, such as a tight crawl space or attic, it may require additional time and effort for the technician to clean it properly.

This can result in higher labor costs and potentially increase the overall cost of the service. So, when considering the cost breakdown of furnace cleaning, it’s essential to keep accessibility in mind.


The season in which you choose to clean your furnace can have an impact on the cost. Typically, furnace cleaning services are in high demand during the colder months when people rely heavily on their heating systems.

This increased demand may lead to higher prices for furnace cleaning services. On the other hand, scheduling your cleaning during the offseason, such as summer or early fall, could potentially save you some money as service providers might offer seasonal discounts or promotions.

So, if you want to keep your costs down and avoid peak pricing, consider getting your furnace cleaned before winter arrives or during the warmer seasons when there is less demand for these services.

Additional Costs and Considerations

There are several additional costs and considerations to keep in mind when it comes to cleaning your furnace. One important factor is whether or not you need duct cleaning along with the furnace cleaning.

Duct cleaning can significantly increase the overall cost, ranging from $250 to $500. It’s worth noting that some people question the necessity of expensive duct cleaning procedures.

Another consideration is the type of furnace you have. The average cost of cleaning an oil furnace is around $100, while other types may fall within a different price range. Additionally, if your furnace requires any repairs or replacement parts during the cleaning process, this will also add to the total cost.

Lastly, it’s important to consider ongoing maintenance for your furnace. Some homeowners opt for a yearly maintenance plan which typically includes two tune-ups per year and can cost between $200 and $400 annually.

While this may be an added expense upfront, regular maintenance can help prevent costly repairs down the road.

DIY vs. Hiring a Professional for Furnace Cleaning

Before you decide to clean your furnace on your own, it’s important to understand the difference between DIY furnace cleaning and hiring a professional. This comparison will help you make an informed decision based on cost, time, and the complexity of the task.

Aspects DIY Furnace Cleaning Professional Furnace Cleaning
Cost The cost of DIY furnace cleaning can vary depending on the materials you may need to purchase. However, it will generally be cheaper than hiring a professional. The average cost of professional furnace cleaning varies from $269 to $486, with additional costs if duct cleaning is involved which ranges from $250 to $500.
Time and Effort Doing it yourself can be time consuming and physically demanding, especially if your furnace is in poor condition. Professional cleaning services will save you time and effort, as they handle the entire cleaning process, including any necessary disassembly and reassembly.
Quality Unless you have substantial knowledge and experience, DIY cleaning may not be as thorough as a professional cleaning. Professionals have the training and tools to provide a deep clean that can improve your furnace’s efficiency and lifespan.
Additional Services DIY cleaning typically only covers the basic cleaning of the furnace. If your furnace needs further maintenance or repairs, you’re on your own. Professional services often include inspection, maintenance, and repairs. For example, a maintenance plan can cost between $200 and $400 annually, and typically includes two HVAC tune-ups per year.

Ultimately, the choice between DIY and professional furnace cleaning depends on various factors such as budget, available time, furnace condition, and your comfort level with performing the task yourself.

How to Save Money on Furnace Cleaning Cost

  • Take advantage of furnace cleaning specials or promotions offered by service providers.
  • Consider bundling furnace cleaning with other HVAC services, such as duct cleaning or furnace tune – ups, to save money.
  • Regularly replace your furnace air filter to prevent the buildup of dirt and debris, which can lead to more expensive cleaning procedures.
  • Schedule your furnace cleaning during the off – season when demand is lower and prices may be more competitive.
  • DIY furnace cleaning can save you money, but make sure you have the necessary knowledge and tools to do it safely and effectively.
