If your HVAC system is trying to circulate air through dirty filters, it works harder and costs you more to heat or cool your home. Changing or cleaning filters monthly – or at least every three months – will make it easier on your heating and cooling system and will even make the air in your home cleaner and healthier for your family. Also, don't ignore HVAC system maintenance. Servicing your heating and cooling system every one or two years can cut your bills by 3% to 10%.
