How to Choose the Right Energy-Efficient Chest Freezer

Once you start shopping, you’ll quickly realize there are tons of options when it comes to energy-efficient chest freezers. Follow this cheat sheet to pick the one that best suits your space, usage needs, and budget:
- Consider size carefully: Bigger isn’t always better when it comes to chest freezers. Select a size with just enough capacity for your expected food storage and freezing needs. Measure spaces beforehand to ensure a proper fit. Too large will waste money and energy. Too small will frustrate daily use.
- Seek out manual defrost models: Chest freezers that require manual periodic defrosting are generally more energy efficient than self-defrosting models which frequently cycle to prevent ice buildup. Just account for the manual effort of occasional defrosting.
- Verify excellent insulation: Multiple inches of high-density foam insulation make a huge difference in energy efficiency by retaining cold air better. This allows the compressor to work less to maintain interior temperatures.
- Watch for air leaks: Quality construction with robust door gaskets, weather stripping, and sealing prevent cool air loss. This improves freezer performance and efficiency.
- Evaluate compressor types: Reciprocating or dual compressors often offer better energy efficiency versus single compressors in larger units. But adaptive single compressors can be efficient too.
- Compare energy guides: Look at estimated kWh/year to judge efficiency between models rather than just the freezer’s physical size. Lower numbers indicate better efficiency.
- Weigh extra features: Factor in usability extras like shelving, baskets, automatic defrost, and interior lighting. Just don’t overpay for unnecessary add-ons you won’t use.
- Do the math: Calculate the energy cost difference between an inefficient old model you own and a newer, more efficient chest freezer. Weigh this against purchase price and expected lifespan to get a true sense of savings.
Some legwork upfront shopping carefully for the right size, build, design and features pays off over the 10-15 year lifespan of your new energy-saving chest freezer. Properly maintaining your new freezer also maximizes efficiency, so don’t neglect periodic manual defrosting, door gasket checks, cleaning, and more. Invest in efficiency now and you’ll keep saving year after year.
Your Energy-Efficient Chest Freezer Questions Answered

If this is your first foray into the world of energy-efficient chest freezers, chances are you still have some questions about getting the right model and using it properly. Here are answers to some of the most common questions we get:
How much energy do chest freezers use?
The average chest freezer can use between 300-1200 kWh per year depending on size, age, and efficiency. By comparison, newer ENERGY STAR certified models use at least 10% less energy, with the most efficient units cutting electricity use by 70% or more versus dated models.
How can I calculate the energy costs of running a chest freezer per year?
Take the kWh/year rating listed for the model and multiple it by your local electricity rate per kWh. For example, a freezer using 500 kWh/year at an electric rate of $0.12/kWh would cost $60 annually to run (500 kWh x $0.12 = $60).
Should I keep my existing older chest freezer or buy a new energy-efficient model?
Do a break-even analysis comparing your old freezer’s operating costs vs. a newer model’s purchase price and energy savings. If a new freezer will pay for itself in energy savings over 5-7 years, it’s probably worth upgrading.
Where is the best place to locate a chest freezer for efficiency?
Place it in a ground floor interior room away from heat sources like appliances or direct sun. Garages and basements work well to take advantage of cooler ambient temperatures. Keep some clearance around it for ventilation.
How often should I defrost a manual defrost chest freezer for optimal efficiency?
About every 3-6 months is ideal depending on usage levels. Defrosting prevents ice buildup from acting as insulation that makes the compressor work too hard. Manual defrost units use less energy overall.
What are the best tips for organizing a chest freezer?
Use baskets to group similar items. Separate zones for meats, baked goods, fruits/veggies. Label and date items. Keep a log of contents on the lid. Rotate older stock forward. Don’t overfill.
How long can food safely stay frozen in a chest freezer due to a power outage?
A fully stocked freezer will keep food frozen for around 48 hours if the door stays shut. A half-full unit about 24 hours. Get coolers ready if power failures will be prolonged.
What are signs my chest freezer may not be energy efficient anymore?
Thick ice buildup inside, items not fully frozen, food spoiling quickly, exterior feeling hot, increased noise or rattling, high electric bills point to inefficient operation.
What maintenance helps keep a chest freezer running efficiently?
- Defrosting every 3-6 months
- Checking/replacing worn door gaskets
- Cleaning condenser coils every 2-3 years
- Keeping door closed and organizing contents efficiently
Making the move to an energy-efficient chest freezer powered by the latest tech for energy savings and food preservation is one of the best investments you can make for your home and wallet.
