I got a quote for a HVAC replacement. The dealer wants to install a 5 ton condenser 2A7A8060B with a 4 ton air handler 2TEE3F49A due to space restrictions in the closet. According to ARI standards this will give 58500 Btuh, an EER rating of 10.80 and a SEER rating of 16.50
Is this mismatch in tonnage OK? I am a little worried since I thought tonnage should be the same.
