The Importance of Changing Your Furnace Filter

The Importance of Changing Your Furnace Filter

Your furnace filter should be changed at least every three months, but some filters may need to be changed more or less often depending on the type of filter and the type of furnace you have. But a general rule to follow is to change your furnace filter every three to six months, depending on the type of filter you have and the amount of use your furnace sees.

A clogged filter will make your furnace work harder and can even lead to it breaking down. Furnace filters play an important role in keeping your furnace running smoothly and efficiently. They keep dirt and dust from entering the furnace and clogging the filters, which can cause the furnace to overheat and break down. Changing your furnace filter on a regular basis can help you avoid costly repairs and keep your furnace running safely and smoothly.

Furnace Filter Location

A furnace filter should be placed in the return air duct, which is usually in the ceiling or on the floor. It’s important to place a furnace filter in the correct spot to ensure your furnace is running at its best. Improper placement can lead to decreased airflow and can even damage your furnace. The furnace filter should be placed in the return air duct.

This is the duct that brings air back to the furnace from the rooms in your home. The filter should be located as close to the furnace as possible. If the filter is placed in another location, such as the supply air duct, it can cause the furnace to work harder than necessary and may even damage the furnace. The filter should never be placed in the exhaust duct.

Choosing the Right Size Furnace Filter

Choosing the Right Size Furnace Filter

The frequency with which you should change your furnace filter depends on a variety of factors, including the type of filter you have, the size of your furnace, the number of people living in your home, and the type of heating system you have. In general, you should change your filter every one to three months, but be sure to check the manufacturer’s recommendations for your specific filter.

If you have a pleated filter, you should change it every month; if you have a fiberglass filter, you can wait up to three months. If you have a high-efficiency furnace, you may need to change your filter more often, every two to four weeks. And if you have a special filter designed to remove smoke or pollen and allergens, you may need to change it every week.

Be sure to measure the size of your filter before you go to the store to buy a replacement, so you can ensure that you have the right size. Furnace filters come in a variety of shapes and sizes, so it’s important to get the right one. If you have a standard-sized filter and don’t have the correct measurements, the filter won’t fit properly and it won’t be able to do its job.

These are just a few rules to follow when it comes to changing your furnace’s air filter.
