How to lower the cost of running a chest freezer
Chest freezers are among the most efficient appliances per cubic foot because cold air sinks and stays inside when the lid opens. Like a refrigerator, the compressor cycles on and off — we assume about 40% of the time. Placement matters: a freezer in a hot garage runs much longer than one in a cool basement.
- Keep it in a cool spot away from the water heater, furnace and direct sun.
- A full freezer holds cold better — fill empty space with jugs of water.
- Defrost when ice builds up beyond a quarter inch.
