How to Change a Furnace Filter

Fire & Ice Team

Fire & Ice Heating & Air Conditioning preach this like the fiery pastor or minister on Sunday morning: If you want to keep your HVAC systems operating at peak efficiency, change your furnace filters religiously. To help you out, let's talk a little bit about the process and hopefully make it easier for you.

Choosing the right one

There are many different shapes and sizes of furnace filters. Before you start, check your owner's manual to make sure you are buying the correct filter. Beyond that, there are a variety of options you can choose to filter out different levels of dust, viruses, and smoke.

Where the heck is it?

Your next task is to locate the filter. Most of the time it's pretty easy but you may have to remove a panel to find it.

  1. Turn your HVAC unit off before doing any maintenance. You don't want it kicking on while you're changing out the filter or taking off panels.
  2. The furnace filter is always located between the air return duct and air supply (conditioned air) duct.
  3. Determine which way the air flows. It always flows from the return to supply.

Now comes the easy part

Once you've located the filter it should be easy to pull it out and slide the new one. This is where you have to remember the direction of airflow. There will be an arrow on the new filter, and it must point in the direction the air is moving. In some cases, the furnace filter can catch on some rough edges when you're trying to slide it in. Don't get frustrated. Just take your time and wiggle it around and it will slide into place. If it's super complicated, in a tight space, or you're completely unsure let us know. We are happy to take a look and change your filter during your maintenance visit.

Washable filters

Some HVAC systems have washable semi-permanent air filters. There's nothing wrong with them as long as you wash them on a regular basis. If you don't like the hassle of washing, you can usually replace them with a paper or fiberglass filter.
