How to tell if your furnace filter needs changing
If you have a furnace, you know that one of the most important aspects of keeping it running smoothly is regularly changing the filter. But how do you know when it’s time to change the filter? Here are a few signs to look out for:
1. The furnace is running less efficiently than usual. This might be evidenced by longer heating cycles or higher energy bills. 2. The furnace is making strange noises.
If you notice banging, rattling, or other unusual sounds coming from your furnace, it could be a sign that the filter is clogged and needs to be changed. 3. There is visible dust or debris coming from the furnace vents. This is a pretty clear sign that the filter is no longer doing its job and needs to be replaced.

How to check furnace filter
If your furnace has been running non-stop this winter, it’s a good idea to check the filter to see if it needs to be replaced. A furnace filter protects your furnace from dirt and dust, and if it gets too clogged, it can restrict airflow and cause your furnace to work harder than it needs to.
To check your furnace filter, open the furnace door and locate the filter.
It’s usually housed in a metal or plastic frame. Once you’ve found it, hold it up to a light to see if it’s dirty. If it looks clean, you can put it back in and close the furnace door.
If it’s dirty, however, you’ll need to replace it. Replacing a furnace filter is easy – just make sure you get the right size for your furnace. Furnace filters come in a variety of sizes, so it’s important to measure the filter opening before you buy a new one.
