Your furnace’s filter is a critical component of your heating system. It traps dust, dirt, and particles so that the air flowing in your space is high quality and your HVAC system runs efficiently. If you are not sure when to change yours, look for the following signs.

When Do You Need to Replace the Furnace Filter?

1. Sights & Smells

Look for a buildup of dirt and dust; the filter will appear gray and grimy if there is. Also, smell the unit as it is running. If there is a burning smell, there may be a few issues, but one might be an excess of dust. Finally, if the airflow is restricted, there is too much dust clogging this component.

2. Cycling System

If you notice the furnace takes longer than usual to reach ideal temperatures, dust and particles are interfering with its operation. You may also notice that the furnace cycles on and off more frequently. Check the filter’s quality to see if it’s overflowing with dust and dirt.

3. Dusty Home

A moderate amount of dust is normal. However, when the amount seems to increase when you turn on the heat, the filter is blowing particles into your living space.

4. Increased Allergens & Illness

A rise in allergies, respiratory trouble, and sinus issues points to a clogged filter. The particles that are supposed to be trapping are now creeping into your indoor air and compromising the health of you and your family.

5. Rising Costs

Dirty filters reduce efficiency, and you will begin to notice your heating bill getting higher with each month. When you see a jump in fees, check the filter and replace it as soon as possible.

6. Manufacturer Recommendation

Check your manufacturer’s recommendations for changing the filter. Frequency depends on the type you have, along with other conditions such as pets and smokers. Filters should usually be replaced every three or four months.
