Do all 12 SEER air conditioners perform the same?
When comparing different brands of air conditioners, a 12 SEER 3 ton brand “A” will offer the same COOLING operating costs as a 12 SEER 3 ton brand “B”. However, one brand may do a better job of removing moisture from the air. The better the moisture removal, the more comfortable you will be-even at a warmer temperature. An air conditioner that is over-sized (too large) will cool a home very quickly but, due to the shorter “run” time, it will not remove as much moisture. A slightly undersized air conditioner that must run more often will actually provide a more comfortable home, better humidity control, and at a lower operating cost.
