Many furnace problems have the same root cause—a dirty air filter. Neglected furnace filters build up dust and debris and can prevent air from freely flowing through the system. A clogged filter can trip the safety switch and cause your furnace to shut down and in extreme cases can even cause your heat exchanger to crack.

With winter coming to an end, you’re probably going to use your furnace less—so it’s a perfect time to check and change your furnace filter. Remember, your central air conditioner uses the same air filter so it’s important to change it regularly.

How often you have to change your filter will depend on a number of factors. Homes with animals or excessive dust will need to have filters changed more frequently. Additionally smoking in the home can significantly decrease the lifespan of filters. Read more about when you should change your filter here.

Remember to follow these helpful tips when replacing furnace filters:

• Turn off the power before removing and replacing the filter.
• Ensure the arrows on the filter face towards the furnace and away from the return duct.
• Always keep a stock of filters on hand so that when you need to change it, it’s available and you don’t have to go to the store.

Replacing a furnace filter is an easy task, but one that many homeowners overlook. Please don’t neglect this very important maintenance chore.
