Heating and cooling account for 48% of a home's energy use. With utility rates in California, this is big money. While upgrading to the most efficient heating and cooling system is a smart choice, doing so can be expensive. Another easier way to cut your heating/cooling costs by hundreds every year is to properly insulate your home.
How Can I Save Money?
ENERGY STAR® estimates that an insulation upgrade saves 15% on heating and cooling costs. Actual savings may be higher, especially if your home lacks a baseline level of insulation in the walls and attic.
