What Changed and Why

Starting January 1, 2023, the Department of Energy introduced a new efficiency testing standard called SEER2, replacing the original SEER rating that had been in use for decades. The change wasn't about making equipment more efficient — it was about making the testing more realistic. The old SEER test used a very low external static pressure (0.1 inches of water column), which doesn't reflect real-world duct resistance. SEER2 testing uses a higher static pressure (0.5 inches), which more closely matches what systems actually experience in the field. The result is that SEER2 numbers are slightly lower than the old SEER numbers for the same equipment.

How the Numbers Compare

A system rated at 14 SEER under the old standard would be roughly 13.4 SEER2 under the new one. A 16 SEER unit is approximately 15.2 SEER2, and an 18 SEER unit comes in around 17.2 SEER2. The equipment itself hasn't changed — only the way it's tested. This matters because the new federal minimum efficiency in the Southeast region (which includes Asheville and all of Western North Carolina) is 15 SEER2 for air conditioners, which is roughly equivalent to what used to be called 16 SEER.

What This Means for Your Purchase

If you're shopping for a new AC or heat pump, you'll see SEER2 ratings on all new equipment. Don't be alarmed if the number seems lower than what you expected — a 15.2 SEER2 system is effectively the same as the old 16 SEER. The key is to compare SEER2 to SEER2, not SEER2 to old SEER. Quality Comfort will walk you through the ratings and help you understand exactly what level of efficiency you're getting.

Regional Minimums Matter

The new federal standards set different minimums for northern and southern regions. Here in WNC, the southern standards apply: 15 SEER2 for air conditioners and 15 SEER2 / 8.8 HSPF2 for heat pumps. Any system we install meets or exceeds these requirements. We'll help you choose the right efficiency level — whether that's the new baseline or a premium 20+ SEER variable-speed system — based on your comfort goals and budget.
