ComfortComfort series, tier 1 of 3 in the range.
Comfort Series AC
Single-stage, dependable, sensibly priced.
Central air conditioners split into three families, and the difference between them is how finely they can modulate their output.
Single-stage equipment runs flat out or not at all. Two-stage spends most of its life on a lower setting, giving longer cycles and better moisture removal. Variable-speed modulates continuously, which is why it is both the quietest and the best at holding humidity steady.
Whichever tier you choose, the outdoor unit has to be matched to an indoor coil and blower rated to work with it. Mismatched pairs do not deliver their labeled efficiency and can void warranties.
