How to compare energy-efficient appliances before buying
The lowest purchase price is not always the lowest-cost appliance to own. A useful comparison combines the price, expected years of use, EnergyGuide estimate, local electricity or fuel rate, water use, capacity, repair history, warranty, installation requirements, and available rebates. ENERGY STAR certification identifies models that meet current EPA efficiency specifications, while the yellow EnergyGuide label helps compare estimated energy use with similar models. Before paying, confirm the exact model number in official product and recall databases and calculate savings using your household’s actual usage and local rates.
What matters first
- Use the EnergyGuide label to compare estimated annual energy use and operating cost among similar-size models; the estimate uses typical use and a national average energy price, so local cost can differ.
- ENERGY STAR certification and the EnergyGuide label answer different questions: certification identifies qualifying efficient models, while EnergyGuide supplies model-specific consumption and comparison information.
- Capacity, dimensions, ventilation, electrical or gas connections, delivery, haul-away, installation, warranty, and likely repair costs can outweigh a small efficiency difference.
- Rebates and special offers can depend on ZIP code, utility, exact model, purchase date, installer, and application timing. A current recall check adds an important safety screen.
Verify before spending
- 1Shortlist models with the capacity and dimensions you need, then compare their official EnergyGuide labels and ENERGY STAR Product Finder records side by side.
- 2Replace the national-average EnergyGuide rate with your local utility rate and estimate annual cost using your household’s likely usage.
- 3Search current rebates by ZIP code and verify eligibility, dates, proof-of-purchase, model-number, installation, and submission requirements before ordering.
- 4Search the full manufacturer and model number in the CPSC recall database, then compare delivered price, installation, warranty, expected operating cost, and return terms.
