SEER sounds good. Do all 13 SEER units perform the same?
If a unit is rated a 13 SEER, no matter what brand, it will provide the same operating costs, assuming you are comparing the same Tonnage units (like a 13 SEER 3 Ton from Brand X and a 13 SEER 3 Ton from Brand Y). What may vary is the unit’s ability to remove moisture from the air. A unit must be properly sized for your home to provide adequate run time (not too long, yet not too quick) to efficiently cool your home while removing sufficient amounts of moisture. An air conditioning unit is best with slightly more run time, allowing more moisture to be removed, thus providing comfortable humidity control with lower operating costs.
