Franklin's location in the Little Tennessee River valley creates a moderate mountain climate, but the distance from major service centers means many homes go longer between HVAC maintenance visits. Macon County's mix of year-round residents and seasonal mountain homeowners creates varied demands — some systems sit idle for months, then must perform immediately. Natural gas availability is limited outside the town core, making propane and heat pump expertise essential.

The Shift From SEER to SEER2

On January 1, 2023, the Department of Energy rolled out a revised efficiency testing protocol known as SEER2, retiring the original SEER metric that had served the industry for decades. The purpose of the change was not to mandate more efficient equipment — it was to make the test itself more representative of actual field conditions. Under the legacy SEER test, external static pressure was set at just 0.1 inches of water column, far lower than what most real-world duct systems create. SEER2 raises that figure to 0.5 inches, aligning the lab test more closely with installed performance. Because of the tougher test conditions, SEER2 numbers come out slightly lower than old SEER numbers for identical equipment.

Converting Between the Two Scales

Equipment that carried a 14 SEER rating under the old protocol lands at roughly 13.4 SEER2 under the new one. A former 16 SEER system translates to approximately 15.2 SEER2, and an 18 SEER unit becomes about 17.2 SEER2. No hardware has changed — only the measurement method. The practical implication is that the new federal minimum for the Southeast region (which covers Asheville and all of Western North Carolina) stands at 15 SEER2 for air conditioners — roughly the same performance as what was previously labeled 16 SEER.

How This Affects Your Buying Decision

When you shop for a new AC or heat pump, every unit on the market will display a SEER2 rating. If the number appears lower than you anticipated, remember that a 15.2 SEER2 unit performs identically to the old 16 SEER label. The important rule is to compare SEER2 against SEER2 — not against legacy SEER figures. Quality Mechanical will guide you through the ratings and make sure you understand the actual efficiency level of any system you are considering.

Regional Standards in WNC

Federal regulations establish separate minimums for northern and southern climate zones. Western North Carolina falls under the southern standard: 15 SEER2 for air conditioners and 15 SEER2 / 8.8 HSPF2 for heat pumps. Every system Quality Mechanical installs meets or exceeds these thresholds. We will help you select the efficiency tier that aligns with your comfort priorities and budget — from the new baseline all the way up to a premium 20+ SEER variable-speed platform.
