Beware of “Up To” Efficiency Ratings
One way to compare systems you’re considering is to look at their efficiency ratings. Unfortunately, some companies fudge the numbers by adding two little words to their descriptions: “up to.”
When you see an ad claiming a system has an efficiency of “up to 20 SEER2” or “up to 10 HSPF2,” they aren’t representing the actual efficiency of the system.
Why Are "Up To"
Ratings Misleading?
Manufacturers test many different combinations of indoor units, o nits, coils, air handlers, and furnaces. The
highest-performing combination might achieve the advertised “up to” efficiency rating, but it’s not guaranteed.
Though a heat pump might be marketed as “up to 20 SEER2,” the specific combination proposed for your home might only achieve 16.5 SEER2.
Without verifying the exact system combination, there’s no way to know the true efficiency of your future system.
What Are AHRI-Certified Ratings?
AHRI stands for the Air-Conditioning, Heating, and Refrigeration Institute. Ratings are based on the organization’s independent tests. AHRI ratings certify HVAC equipment combinations to verify their actual performance and efficiency.
We believe homeowners deserve to know exactly what
they’re getting, not just the best-case number from a
brochure. That’s why we provide AHRI-certified ratings
whenever available.
An AHRI certification confirms that:
- The indoor and outdoor equipment have been tested together.
- The published efficiency ratings are accurate and independently verified.
- The system qualifies for applicable utility rebates, tax credits, and incentive programs when required.
- Homeowners know exactly what level of performance they are purchasing.
Rather than relying on a manufacturer’s best-case “up to” rating, an AHRI certificate provides a verified efficiency rating for the exact equipment combination being installed in your home.
