How Much Do Furnace Cleaning Cost?

Furnace MaintenanceIf you’re a homeowner, you know the importance of keeping your furnace in good condition. Not only can a dirty furnace lead to poor indoor air quality, but it can also be a safety hazard. That’s why regular furnace maintenance is essential, and one of the most critical steps in that process is furnace cleaning.

So, how much do furnace cleanings cost? The answer varies depending on a few factors.

Average Cost of Furnace Cleaning

The cost of furnace cleaning can vary depending on several factors. However, the average cost falls between $150 to $300. When hiring a professional, the cost will usually include cleaning the furnace and a routine checkup to ensure everything is working correctly. Cleaning a furnace includes removing dirt and debris that can affect the function of the furnace.

According to HomeAdvisor, the national average cost of furnace cleaning is $237. However, prices can range anywhere between $80 to $500. Large urban areas and seasons when people use their furnaces more can result in prices being on the higher end of the range. When estimating the costs of furnace cleaning, it’s essential to do proper research to ensure you get the proper value for your money.

Factors That Affect the Cost of Furnace Cleaning

Several factors can affect the cost of furnace cleaning.

Size of the furnace

The size of your furnace is one of the most significant factors that impact the cost of cleaning. Larger furnaces require more time and effort to clean and, as a result, cost more money. For instance, suppose you have a furnace that is over 100,000 BTUs. In that case, it will likely take longer to clean, and you may be charged up to $100 more than someone with a smaller furnace. If you are unsure of the size of your furnace or how it can impact the cost of cleaning, talk to your HVAC technician before scheduling a cleaning.

Location of home

The location of your home is another factor that can impact the furnace cleaning cost. For example, if you live in an area with a higher cost of living, the price of furnace cleaning may be more than in a lower-cost area. Additionally, the time of year can impact how busy HVAC technicians are in your area and may result in higher prices. If you are on a budget, it may be worth waiting until the off-season to have your furnace cleaned.

Company hired

The company you hire to clean your furnace can also impact the final cost. While choosing the company with the lowest price may be tempting, it’s essential to ensure that they are experienced and reputable. A less experienced company may provide subpar service or recommend unnecessary repairs, which can cost you more in the long run. When hiring a company, read reviews, compare prices, and ask for references.

Additional Costs

If your HVAC technician discovers that your furnace needs additional repairs or parts, you can expect additional costs. For example, if your furnace’s blower motor is on its last leg, you may need to replace it, which can cost anywhere from $300 to $600. Similarly, other parts needing replacement, such as the igniter or control board, can add expenses to your final bill. It is essential to remember that additional costs often depend on the severity of the issue, the type of furnace, and its age.

In addition, preventative maintenance such as replacing filters, cleaning ductwork, and addressing minor issues are essential to consider to repair costs. These additional costs may not seem significant, but they can add up over time. Proper maintenance of your furnace will keep it running more efficiently and prevent costly repairs down the road.

Importance of Regular Furnace Cleaning

Keeping your furnace clean is necessary for improving its lifespan and the safety and comfort of your home. A dirty furnace must work harder to produce heat and can become a hazard if improperly maintained. Here are some of the importance of regular furnace cleaning and why it should be a part of your routine household maintenance.

Prevents Health Hazards

When your furnace is not cleaned regularly, dust, pollen, and other contaminants can accumulate inside the air ducts, making their way into the air you breathe. It can trigger respiratory problems that can cause sneezing, coughing, and allergies. Regular maintenance and cleaning reduce the accumulation of these contaminants, helping to prevent them from entering your home.

Help Reduce Energy Costs

When your furnace is clean, it runs more efficiently. When it’s clogged with dirt and debris, it has to work much harder to keep up with the demand for heat, which can increase your power bill. Regular cleaning can help reduce your energy costs by keeping your furnace running at peak efficiency.

Improves Safety

A dirty furnace poses a risk of electrical fires, carbon monoxide leaks, and other hazards. Frequently cleaning your furnace will help detect potential problems before they cause harm. Hiring a professional to inspect your furnace and help identify any safety issues is essential.

Extends the Life of Your Furnace

Regular cleaning and maintenance of your furnace can prolong its lifespan, which saves you money in the long run. When your furnace is clogged with dust and debris, it has to work harder, which puts more strain on the unit. It can lead to early breakdowns, requiring regular cleaning and maintenance to restore it properly.

Preserve Warranty

Most furnace manufacturers require annual maintenance to maintain the warranty. Ignoring the recommended maintenance and cleaning can void the warranty, meaning any repairs or replacements will come out of pocket. Keeping your furnace clean may take a few hours, but the investment is worth it to keep your home safe and comfortable.


In conclusion, the cost of furnace cleaning varies depending on a few factors, including the size of your furnace, location, and the company you hire. While the average cost is between $150 and $300, it’s important to remember that regular furnace maintenance is essential to ensure your furnace runs efficiently and safely. So, while the cost may seem high, the benefits of regular furnace cleaning far outweigh the cost.
