Most homeowners know that they’re supposed to change their furnace’s air filter to keep the appliance running smoothly and in good repair. But do you know why changing the filter helps and how to do it? Watch this video for a quick look at furnace air filters.
If your furnace’s air filter is dirty, the unit will use more energy. A dirty air filter will also circulate unclean air through your home, which can trigger allergy and asthma symptoms. Failing to replace the filter can eventually lead to furnace repair. In most furnaces, the filter is located in the top half of the unit, where the air intake is. When you change the filter, it’s a good idea to write the date on it so you know when it’s time for replacement.
