Furnace Maintenance: How Often You Should Do It and Why


Furnaces are essential to your home’s heating system and are responsible for keeping your home warm in the winter. Proper furnace maintenance is vital to ensure that it runs smoothly and safely and to help you avoid costly repairs or replacements. 

Read below to know how often you should do furnace maintenance and why.

How Often Must You Maintain Your Furnace?

Furnace maintenance is recommended annually, usually at the beginning of the winter season. This is because the furnace accumulates dust and dirt over time, which can cause problems with the blower motor and other components. Additionally, worn-out parts and filters can reduce efficiency and increase fuel costs.

Regular maintenance can encourage you to avoid the need for emergency furnace repair. During a maintenance visit, a technician inspects the furnace, cleans out any dust or dirt, and replaces any worn-out parts. They will also check the blower motor, oil level, and other components to ensure they are working correctly. Additionally, they may inspect the chimney and flue to ensure it is not blocked or leaking.

In addition to the annual maintenance, you should regularly inspect your furnace. Check the air filter every month and change it when necessary. Check the air ducts for blockages, and make sure the thermostat is functioning correctly. Additionally, you should check for any signs of rust on the furnace since rust can indicate a leak.

By scheduling regular furnace maintenance, you can help ensure your furnace runs efficiently, safely, and at its peak performance. Doing so can help you save money on energy bills, reduce the risk of fires, and keep your home or business comfortable all winter long.

Why Is Furnace Maintenance Important?

Regular maintenance helps to ensure that your furnace is running at peak performance and is not wasting energy. This can aid you in saving money on your energy bills and can help extend your furnace’s life. Your technician can also spot potential problems and make minor repairs before they become more costly.

Not only is regular maintenance necessary for the safety and efficiency of your furnace, but it’s also vital for your health and safety. A well-maintained furnace will reduce the risk of carbon monoxide poisoning, which can be fatal. It’s also essential to check for signs of mold, which can be a health hazard.

What Happens If You Don’t Maintain Your Furnace?

If you don’t keep up with regular maintenance and service, your furnace can become a fire hazard. As dirt and dust build up, they can block the airflow, causing the furnace to overheat and potentially cause a fire. Additionally, a clogged filter can cause your furnace to work harder, resulting in higher energy bills.

Failing to maintain your furnace can also lead to a decrease in efficiency. As dust and dirt accumulate in the system, they can reduce airflow and the heating system’s effectiveness. This can cause your furnace to run longer and cost you more money in energy bills.

Finally, a neglected furnace can lead to a decrease in air quality. As the dust and dirt build up, they can be released into the air, leading to breathing problems for those in the home. This can lead to respiratory conditions such as asthma and allergies.


It’s essential to keep up with proper maintenance for your furnace. Not only will this ensure that your furnace is running safely and efficiently, but it will also help to maintain the air quality in your home.
