EXACT EQUIPMENT PAIRING
Model numbers first. Efficiency claims second.
Record the exact outdoor, indoor and optional furnace combination, then verify that the official pairing evidence covers every model and rating.
Critical verification boundary
CoolCompare does not call a combination “AHRI certified” merely because a reference number was typed. Confirm the exact outdoor unit, indoor coil or air handler, furnace when applicable, capacity, SEER2, HSPF2 and current certificate status in the official directory and manufacturer documentation.
