What EER means
EER is the energy efficiency ratio of a cooling system at one fixed hot outdoor condition, rather than averaged over a season like SEER.
Also called EER2, energy efficiency ratio.
Where it matters on a HVAC job
EER tells you how a unit performs on the hottest afternoons, which matters most in hot, dry climates and for utility rebates that ask for it. Pull it from the matched system rating, not the outdoor unit alone.
