Central Air Conditioner Ratings

A residential central air conditioner's rating is typically measured by its SEER (Seasonal Energy Efficiency Rating). Commercial air conditioning efficiency is often measured by EER (Energy Efficiency Rating) rather than SEER. The "fleet efficiency" of a particular brand is the average efficiency of all of the models sold under that brand name.

Air Cooled Condensers (Brands with 60 or more models)

1. Lennox
2. United Refrigeration Inc.

Notes on Air Conditioner Ratings

Models without a recorded SEER have been excluded.

The "fleet efficiency" or "air conditioner rating" of a particular brand indicates nothing about air conditioner quality or air conditioner durability. In addition, although the fleet efficiency of one brand might exceed that of another, this does not necessarily indicate that any particular model of air conditioner marketed under the first brand out-performs any particular model of air conditioner marketed under the second. To determine whether one model outperforms another, simple compare the SEER of the two models.
