Most cooling systems use electricity, so making sure your home is running as efficiently as possible can help you spend less to operate air conditioners and fans.
How you dispose of an air conditioner can actually be legal or illegal. There are steps to take to do the right thing. Many units will have chemicals or refrigerant in them which must be disposed of safely.
According to the US Department of Energy’s ENERGY STAR® program, leaky ducts in attics or crawl spaces can account for 20 percent or more of a home’s heating and cooling energy losses.
