Business owners researching new commercial HVAC equipment have likely encountered SEER2 ratings, an updated efficiency measurement that replaced the previous SEER standard. Old Glory Air Conditioning and Heating explains what this change means for commercial equipment decisions.
SEER2 was introduced to provide more accurate, realistic efficiency measurements by testing equipment under conditions that better reflect actual operating environments compared to the previous testing methodology used for standard SEER ratings.
The updated testing procedures account for factors like external static pressure in a more realistic way, providing efficiency numbers that better represent how equipment actually performs once installed in real-world commercial applications.
Because the testing methodology changed, SEER2 ratings for equivalent equipment often appear as somewhat different numbers compared to the old SEER scale, which can initially cause confusion when comparing older and newer equipment specifications.
When evaluating commercial HVAC options, it's important to compare SEER2 ratings against other SEER2 rated equipment, rather than attempting to directly compare a SEER2 number to an older SEER rating from previous equipment.
Current regulations establish minimum SEER2 efficiency requirements that new commercial equipment must meet, meaning even baseline new equipment reflects improved real-world efficiency standards compared to older installed systems.
When selecting new commercial HVAC equipment, understanding SEER2 ratings helps you make accurate efficiency comparisons between different available options, supporting more informed decision-making for your business investment.
Since SEER2 testing better reflects real-world conditions, the efficiency ratings you see should provide a more accurate expectation of actual energy performance once your new commercial system is installed and operating.
Given the relatively recent transition to SEER2 standards, working with an HVAC professional who can clearly explain how these ratings apply to your specific equipment options helps ensure you're making comparisons on an accurate, apples-to-apples basis.
While SEER2 efficiency is an important consideration, it's worth balancing this against proper sizing, equipment reliability, and your specific commercial space's needs when making your final equipment decision.
Our team helps Arlington area business owners understand SEER2 ratings and make informed commercial HVAC equipment decisions based on accurate efficiency comparisons.
