Seasons are changing and so should your air filters
As summer slowly rolls to a close and everything pumpkin starts to pop up, it’s not only the leaves that need to be changing. Anyone who uses a forced air system to heat and/or air condition their home should change the system air filter.
Air filters should be changed at least every 90 days or 4 times per year. If you’re new to this type of heating/cooling system, you may want to mark your calendar to change the filter at the change of the season. Depending on the type of air handling system you have, how many pets and people, where you live (urban/suburban), and the size of your home, you may want to change the filter more often.
If you only use the air handling system for heat, change the heating system filter before you start the system up. Don’t turn the system on and blow a musty smell throughout your home. Save yourself the hassle of trying to get that smell out of the house.
The hardest part of this process is determining the filter size and then finding it at a local hardware store. The furnace filter is usually located behind the return-air vent or in a slot on the furnace itself. Before you decide the look for or change the filter, turn the furnace off. You are also going to want to have a large garbage bag handy to dispose of the old filter. If you want the particulars of your exact furnace, take a picture of the data plate and search for manufacturer videos.
Regularly changing the filter not only helps keep your air cleaner but also helps your furnace run more efficiently. An efficient running furnace saves you money.
