Why You Need to Change Your Furnace Air Filter Regularly


Your furnace is absolutely critical to your comfort. Not only does it keep you warm all winter, it affects the quality of the air you breathe. And since it works so hard to keep you comfortable, it seems only right that you should take a moment of your time to keep your furnace comfortable, too.

The best favor you can do for your HVAC system is to regularly change the air filter.

How to Change the Filter

Changing your furnace air filter is the only maintenance job you need to do yourself. All other maintenance and repair should be done by a professional, for your safety and for the well-being of your HVAC system.

It’s a pretty easy job: locate the filter, remove it, clean it if it’s reusable or get a new one if it’s disposable, and put it back in place. If you’re not sure how to do it, check your owner’s manual. Or you can reach out to us with any questions about furnace filter replacement in Denton, TX. We’re always happy to help a customer feel confident about doing this task. 

Why Change the Filter

Often, a lot of emphasis is placed on telling people to change the filter, and telling people how to change the filter. Sometimes, the reason why the filter needs changing gets overlooked. And in our experience, knowing the reasons that a task is important helps motivate people to do the task. There are several ways that your furnace benefits from having a clean filter.

  • Efficiency: When your HVAC system is trying to pull air through a clogged filter, it uses more energy and your air circulation decreases. Getting less for greater cost is not a good deal!
  • Wear and Tear: The extra effort used to pull air through a clogged filter puts unnecessary strain on the whole system, and can cause problems that require repair.
  • Life of the Furnace: That wear and tear adds up, and over years, it can dramatically decrease the lifetime of your furnace. Replacing your heating system is costly and inconvenient, and you don’t want to have to do it sooner than expected.
  • Air Quality: The filter traps particles as they pass through your HVAC system. If they can be caught in a nice, fresh filter, they won’t pass out into your home and then into your lungs. Also, a thick layer of dust in your furnace can cause an unpleasant burning smell of hot dust when you turn on your heat. 

How Often to Change the Filter

It is usually recommended that furnace air filters be changed every 1-3 months. However, we’d like to expand on that general advice. You should change the filter every month during times of heavy furnace use, or when for any reason there is a lot of dust in the air, such as when humidity is particularly low or when road work or construction is happening near your home. And when you have regular furnace maintenance, your technician will change the filter during the process of cleaning the entire furnace.
