Changing
your furnace or air conditioning filter regularly (at least every 3
months) is a good idea, but it is hard to know how much energy it
actually saves. Check your filter every month, especially during heavy
use months (winter and summer). If the filter looks dirty after a
month, change it. At a minimum, change the filter every 3 months. A
dirty filter will slow down air flow and make the system work a little
harder to keep you warm or cool – wasting energy. A clean filter will
also prevent dust and dirt from building up in the system – leading to
expensive maintenance and/or system failure. Visit ENERGY STAR Heating and Cooling for more information.
