I just had a Carrier Performance AC installed. The contract called for a 15 SEER unit, but the energy guide tag said it was 14.0 SEER. I emailed the contractor, he told me to check to verify that it was a model number 24APA548A003. I checked, and emailed back that it was not, it was a model 24APA548A310. The full product number is 24APA548A0031010, which is what it says on the energy guide tag.
His email reply was
"Then it's a 15 SEER. Not every Btu size is exactly 15...that's why they normally say (up to 15 SEER)...so yours is probably 14.9 or something. So, it's the right unit."
This does not sound right to me, but I can't find information online about Carrier's model numbers to verify this. Can anyone tell me how to verify for sure what the SEER number is on a Carrier model 24APA548A310?
