Keep your filters clean!
The air filter keeps pollution and debris out of your HVAC system, ensuring proper and efficient operation. A dirty filter will slow down the air flow, making both the furnace work harder to heat your home and your AC work harder to cool it. This wastes energy and can result in higher energy bills. In some cases this can cause expensive damage to your system.
Follow manufacturer’s instructions for changing (or cleaning) air filters in air handlers/furnaces and other home comfort equipment. Some air cleaners require only an annual filter change, while others need more frequent replacement.
