Im confused about what the minimum required a/c SEER rating is for new homes; Ive heard numbers given from SEER 10 to SEER 13. Would you please advise me which SEER rating is correct?
The new Florida Energy Efficiency Code (2004 Glitch Cycle) for Method A specifies that air cooled, split system AC’s sized < 65,000Btu/h (i.e. the vast majority of systems installed in residences, and probably what you are concerned with here) have to be SEER 13.0 or higher. SEER 13 is also the national minimum. Table 607.1.ABC.3.2A in section 13-607.1.ABC.3.2 of the Florida Code specifies this and other equipment efficiency minimums.
