In an effort to encourage people to update their appliances to more energy saving units, while keeping them out of the landfills, some companies offer to pick up the old ones for free, or even in some cases, give you a rebate, check, tax credit or credit on your utility bill.
Consumers Energy has a program now that will pick up and recycle your freezer or refrigerator and give you a check for $30. If you purchase a more efficient appliance, you will get the $30 and reap the benefits of paying less to run it.
The US Department of Energy has a website where you can enter your zip code, and check the items that you would like to have picked up. It will then list the companies in your area that recycle those items, and whether or not there are any cash benefits. You can find that site here: http://www.energystar.gov/index.cfm?c=recycle.pr_refrigerator_rec.
