Have you noticed any worrying signs from your HVAC system? It may be time to replace your furnace filter. Inspecting a furnace filter isn’t hard to do, and there are telltale signs your furnace filter needs to be replaced.
Regularly changing your filters before they become a problem is an important part of home maintenance and will keep your system running smoothly for years. Be on the lookout for these 3 signs your furnace filter needs to be replaced and never be left wondering—“When do I need to change my furnace filter?”
1. Your system is running more than usual
Most of the time, you might not notice your HVAC running in the background. If it’s running smoothly, it won’t make a lot of noise or need to turn on and off repeatedly. So, if you notice your system is running more than usual, it may be time to replace your filters.
The air in your HVAC needs to pass through your filter and when dust or hair blocks airflow, your system will need to work much harder to heat and cool your house. This can lead to higher utility bills and uneven heating and cooling.
2. It’s been a while since you last replaced it
The best time to change your furnace filter is before you begin noticing worrying signs. Furnace filters need to be regularly replaced and if you don’t remember the last time you replaced it, it may be time. But, how often should you replace your furnace filter?
Most furnace filters need to be replaced every 1-3 months. An easy way to check is to look at your filter’s packaging. The intended length of use should be clearly stated on the side. If you meet any of these conditions, you may need to replace them more often.
Replace your filter more often if you:
- Leave windows or doors open frequently
- Have pets
- Are a smoker
- Suffer from allergies
3. Your furnace filter is visibly dirty
Inspecting a furnace filter isn’t hard. All you need to do is find out where it is and remove it to take a closer look at it. A new filter should be free of dust and hair or look white. Replace your filter if it’s been discolored by dust or any other loose debris.
You don’t need any expensive tools when inspecting a furnace filter, but you might need a screwdriver. If your filter is dirty, you’ll be able to see what it’s filtering out of your home. You might notice hair either from yourself or your pet or excess dust. This could be a sign that you may need to change your filter more often than what is intended on the packaging.
