• What does SEER mean? Should I spend more money for a higher SEER unit?

  SEER stands for seasonal energy efficiency ratio. The higher the SEER rating, the more energy efficient the equipment is. A higher SEER can result in lower energy costs. This U.S. Dept. of Energy Web site, www.eere.energy.gov/femp/procurement/pdfs/cac.pdf, can show how to calculate potential energy cost savings of a more efficient unit. The Air-Conditioning and Refrigeration Institute (ARI.org) posts a Certified Ratings directory, which lists SEER ratings of various air-conditioning equipment.

  A ton is the unit of measurement for air-conditioning system capacity. One ton of air conditioning removes 12,000 Btu's of heat energy per hour from a home. Central air conditioners are sized in tons. Residential units usually range from 1 to 5 tons.
