Clean and replace furnace filters regularly to keep your heating and air conditioning system running at top efficiently. Dirty and dusty filters are the reason for nearly half the repair calls to service technicians.  Keep in mind that dirty or plugged filters can actually damage your system components because they reduce air flow that your system needs to run within proper tolerances.  A plugged filter in the heating season for example, could cause damage to your heat exchanger due to high heat from lack of air flow.

 Buying ENERGY STAR products saves money on utility bills and protects the environment. ENERGY STAR is a government-backed guarantee that the appliance you buy meets strict efficiency standards. That's a big plus for households with heating and cooling systems, which are big energy users. 

The EPA says that if one in 10 households bought ENERGY STAR heating and cooling products, the change would keep 17 billion pounds of pollution out of the air.
