Just in case you haven't heard, you may be able to get a rebate for replacing an old, functional appliance with a new energy-efficient one. Rebates (ranging from $45 to $1600, depending on the appliance) are available for refrigerators, freezers, room air conditioners, washing machines, dishwashers, central air conditioners, air-source heat pumps, and hot water heaters.
You need to reserve your rebate beginning April 7 at 7:00 am. You can apply for up to 2 per address, but they have to be in different appliance categories. You must purchase your appliance from April 16 through April 25 (April 16 through 60 days from reservation or waitlist request for central AC, heat pumps, and hot water heaters). You can get a $75 bonus rebate for properly recycling your old appliance.
