Replace your air conditioner’s air filter.
Replacing an air conditioner’s air filter isn’t like the Olympics; it shouldn’t happen once every four years. In fact, the Department of Energy estimates you can save up to 15% on your energy bills JUST by changing your air filters at least every 90 days. These filters serve an important purpose- they remove dirt, dust and other debris from the air and keep those pollutants from building up in the system. When changed regularly, a clean air filter will not only reduce your home’s energy consumption but will also extend the lifespan of the unit.
