Your furnace is one of the essential appliances in your home, so it’s important to keep it in good working condition. By taking the time to do some basic maintenance, you can keep your furnace running smoothly and efficiently for years to come.

Here are six things to check when maintaining your furnace:

1. Check the Air Filter

If you have a disposable furnace filter, it is essential to check it monthly and replace it every three months. Simply throwing the filter down the bin makes your cleaning duties less. However, you can save money differently if you buy a reusable furnace filter.

With a reusable furnace filter, it is important to clean it monthly. While this may seem like a chore, you won’t have to replace the filter any time soon. To clean it, you can simply use soap and water to wipe off dirt and debris.

2. Inspect the Furnace Blower

The furnace blower is responsible for circulating air through the furnace and into your home. Over time, the blower can become clogged with dust and debris, which can reduce its efficiency and cause it to overheat. If it’s not working properly, the furnace won’t be able to heat the air properly.

3. Lubricate the Blower Motor Bearings Yearly

The furnace’s blower motor can fail over time due to dry or damaged bearings, which can cause the motor to overheat. 

To lubricate the bearings on your furnace’s blower motor, you’ll need to remove the engine from the furnace and then lubricate the bearings with a lubricant such as WD-40.

4. Check the Flue Pipes

The flue pipes are responsible for venting exhaust gasses from your furnace. Make sure that is clear and free of obstructions. Also, it is crucial to ensure that the vents are clear and unobstructed so the furnace can function correctly. 

Lastly, you need to check for leaks in your home, as they can be tricky to find. If you think there are some leaks found, it’s best to have a professional come and take a look.

5. Check the Burner Flames and Adjust Them

Burner flames are responsible for heating the air circulating through your home, so it’s vital to ensure that they always burn as efficiently as possible. If they’re not working properly, the furnace won’t be able to heat the air.

If the dirt or debris is blocking the burner, that can cause the flames to burn less efficiently. You can clean the burner by removing it.

6. Have a Professional Inspect It Yearly

Having a professional furnace tune-up every few years is a good idea to help keep your system running smoothly and prevent any small problems from turning into big ones.

A tune-up from an expert will help extend the life of your furnace and prevent expensive repairs or replacements down the road. They can also check the gas line and connections for leaks to make sure they are safe.


Keeping your furnace in the best working condition is vital by checking it regularly and performing basic maintenance tasks. Doing so can prevent potential problems and keep your home warm and comfortable.
