SEER2 vs SEER: The New Efficiency Standards

As of January 2023, the DOE replaced SEER with SEER2, a more rigorous testing protocol that increases external static pressure during testing from 0.1 to 0.5 inches WC. This better simulates real-world ductwork conditions. What does this mean for your next AC installation in Aurora?

The Technical Mechanism

Understanding this principle requires examining the underlying physics. In any closed thermodynamic system, energy transfer follows predictable mathematical laws. The practical application of these laws is what separates clinical HVAC engineering from commodity repair work. At Aurora HVAC Services, we apply these principles on every single diagnostic call, ensuring our Aurora and Fox Valley customers receive empirically validated solutions—not guesswork.

Clinical Application in the Fox Valley

For homeowners in Aurora, Naperville, Plainfield and across the western suburbs, this knowledge translates directly into system longevity, energy savings, and indoor comfort. Our NATE-certified technicians are trained to apply these engineering principles in real-world field conditions, using calibrated instruments and manufacturer-specific diagnostic procedures. The result is a repair or installation that performs to specification—not just today, but for the full intended lifespan of the equipment.
