Check the air filter every month: The longer you keep the same air filter in place, the more dirt, dust, pet dander and other debris it collects. A clogged filter restricts airflow and forces your heating and cooling equipment to work harder, which raises energy costs. Check the air filter and replace it when it appears dirty to maintain adequate airflow.
