SEER2 Standards: Engineering for the New Era

In 2023, the Department of Energy moved from the SEER rating to **SEER2**. This wasn't just a name change; it was a fundamental shift in how HVAC efficiency is calculated, particularly focusing on the **External Static Pressure (ESP)** that systems face in real-world environments like the high-country homes of Coalville.

Real-World Testing for Real mountain Homes

Traditional SEER testing assumed a static pressure of 0.1 inches—a level almost never found in real mountain homes with their complex duct runs. SEER2 testing raises that pressure to 0.5 inches, five times the previous standard. For Summit County homeowners, this means that a "SEER2" system is verified to maintain its efficiency even when working against the higher atmospheric pressures of our altitude. At Hvac Pros, we ensure every new installation is commissioned to meet these new technical mandates, protecting your utility ROI for the long term.
