The SEER2 Transition: Fort Worth Compliance.

The Department of Energy has fundamentally shifted how HVAC efficiency is measured. For Fort Worth homeowners, SEER2 isn't just a label; it is a clinical requirement for all new installations.

SEER vs. SEER2: The Technical Divergence

Standard SEER (Seasonal Energy Efficiency Ratio) was measured under laboratory conditions that rarely reflected real-world structural static pressure. SEER2 utilizes the M1 testing procedure, which increases external static pressure by a factor of five. This provides a much more accurate representation of how a unit will perform in a typical North Texas home.

The 14.3 Requirement

In the Southeast and Southwest regions, including Texas, the new minimum standard for residential split-system AC units is 14.3 SEER2 (equivalent to 15.0 SEER). Installing a unit that does not meet this standard is now a violation of federal technical regulations.
