What is the difference between SEER and SEER2?

• SEER is based on lab testing under ideal conditions
• SEER2 includes more realistic factors like static pressure from ducts, so it gives a clearer picture of real-life performance. 

Is It Worth Upgrading to a Higher SEER2 Unit?

Yes—especially if you want to reduce your energy bills, lower your carbon footprint, and get the most comfort from your system. Higher-efficiency ACs can also help increase the value of your home and extend the life of your system with fewer breakdowns.

Pro Tip: SEER2 is now becoming the new standard across Canada. Many newer AC models are already listed using only SEER2 rating—so if you’re comparing older and newer systems, make sure you’re looking at the same standard!
