How Often Should You Replace Your Furnace Filter?

You rely on your furnace to keep your home warm, safe, and comfortable all year round. In hot climates, a functioning furnace can provide a much-needed cooling effect in the summer months. No matter what season it is, it’s essential to keep your furnace filter maintained and replaced when necessary.

How Often Should You Replace Your Furnace Filter?

The recommended frequency for replacing a furnace filter depends on a variety of factors, such as type of filter, home size, number of occupants, and even the type of furnace. Generally speaking, furnace filters should be replaced every 90 days for optimal performance.

When it comes to the type of filter, certain ones will require more frequent changes than others, depending on the size and amount of debris they can filter out. Sealed fiberglass and aluminum filters can typically last for about 30 days, while pleated filters can last for up to 90 days. If someone in your household suffers from asthma, allergies, or other air-borne illnesses, you may want to consider changing your filter more frequently.

When You Should Check Your Furnace Filter

If you have an older or inefficient furnace, it’s important to check your filter regularly. A dirty or clogged filter can force your furnace to work harder and can cause it to shut down if left unchecked. An inefficient appliance leads to an increased risk of fire or toxic fumes being emitted.

If you are unsure about the condition of your filter, it is best to seek professional advice. A certified technician can inspect your filter, determine the best type for your specific needs, and provide a reliable replacement schedule. In addition, a professional can point out any signs of need for maintenance, repairs, or even replacement of the entire furnace unit.


Keeping your furnace filter changed and maintained isn’t always a fun job, but it’s an important one. Checking and replacing your filter according to the recommended schedule can help you get the most out of your appliance and keep your home warm, safe, and healthy. If you’re not sure when it’s time to replace your filter or are having any other issues with your furnace, don’t hesitate to contact a local reliable appliance repair.
