How Can I Tell If My Product Is ENERGY STAR® Certified?
When shopping for new windows, doors, appliances, or home comfort products, you may notice the familiar blue ENERGY STAR® label. But how can you be sure a product is genuinely ENERGY STAR certified? Understanding what to look for can help you make an informed purchase and maximize your energy savings.

What Does ENERGY STAR Certification Mean?
ENERGY STAR is a program backed by the U.S. Environmental Protection Agency (EPA) that identifies products meeting strict energy efficiency and performance requirements. Products that earn the ENERGY STAR label are independently certified and tested to ensure they meet these standards. https://www.epa.gov/vcs/energy-star
For homeowners, this means lower energy bills, improved comfort, and reduced environmental impact without sacrificing performance.

Look for the Official ENERGY STAR Label
The easiest way to identify an ENERGY STAR certified product is to look for the official blue ENERGY STAR logo on:
- Product packaging
- Product labels or stickers
- Manufacturer specifications
- Product listings online
Be cautious of products that make general energy-saving claims without displaying the official ENERGY STAR mark.
Check the Product Model Number
ENERGY STAR certification applies to specific product models, not necessarily an entire brand or product line. A manufacturer may offer some certified products and some that are not certified.
Before purchasing, locate the exact model number and compare it with official ENERGY STAR records.
Use the ENERGY STAR Product Finder
One of the most reliable verification methods is the official ENERGY STAR Product Finder. This searchable database allows consumers to verify whether a specific product model is currently certified.
The Product Finder includes a wide range of categories, such as:
- Windows, doors, and skylights
- Heating and cooling systems
- Refrigerators
- Dishwashers
- Clothes washers and dryers
- Smart thermostats
- Water heaters
- Electronics and more
Simply enter the manufacturer name or model number to confirm certification status.
Verify Through the Manufacturer
Most reputable manufacturers proudly display ENERGY STAR certification information on their websites. Look for:
- Product specification sheets
- Technical documentation
- ENERGY STAR logos
- Certification details
If you’re unsure, contact the manufacturer directly and request confirmation of the product’s certification status.
Ask Your Dealer or Contractor
If you’re purchasing replacement windows, doors, or other home improvement products, your dealer or contractor should be able to provide documentation confirming ENERGY STAR certification.
