Carrier Infinity Series
Carrier Central Air Conditioner
The Carrier Infinity Series includes four models. Two of these, the 24ANA1 and 24ANB1, have a seasonal energy efficiency ratio (SEER) of up to 21 and run very quietly at 65 decibels. They also earn praise for their dehumidifying power and strong reliability record. The warranty covers all parts for 10 years, but requires registration.
