The Rheem 14-SEER Classic Series Air Conditioner Condenser and the Goodman 13-SEER model R410A are two examples of 3.5-ton air conditioners. The tonnage is a measurement of cooling capacity rather than the physical weight of the unit.
3.5-ton air conditioners provide the superior cooling and performance needed to maintain comfortable temperatures within a larger home. While specifications may differ from one model to the next, these units typically produce over 40,000 cooling British thermal units and weigh a few hundred pounds, making them versatile enough for either ground-level or rooftop installation. Most 3.5-ton air conditioners feature an energy-efficient motor and a powder-coated finish.
