Heating and Cooling Equipment

Now take a look at the systems that keep your home comfortable. Your home's heating and cooling equipment is probably its largest energy consumers. Begin by locating them and giving them a visual inspection. Many homes have a split system, which means you have equipment inside and outside the house. If you have a forced air furnace, check your filters and replace them as needed. Generally they should be changed about every couple of months. Some people use the season change to remind themselves to change filters. If the unit is more than 15 years old, consider replacing it with one of the newer, energy-efficient units.

As part of your equipment check, inspect ductwork for dirt streaks, especially near seams. These indicate air leaks, and they should be sealed. Make a note to insulate any ducts or pipes that travel through unheated spaces. An insulation R-Value of 6 is the recommended minimum.
