I am trying to find the EER of an entire list of units. I have make and model#s. Most are older units, but I am having trouble finding them. Does anyone know of any websites I can use to search for their rated EERs?
Scroll down just under the first picture of the unit to the top of the second page and look at the Model Number Nomenclature. The third number from the far left is 3 which means 13 seer. It's explained.
