With residential air conditioning, efficiency is measured by SEER, or Seasonal Energy Efficiency Ratio. In effect, the higher the SEER rating, the more efficient the system will be. The U.S. recently adopted minimum SEER requirements, currently 14, and any system over 16 SEER is generally considered high efficiency.  A SEER rating over 20 is in the highest efficiency group.

If you’re confused about why efficiency matters, one good reason is cost. A system with a SEER rating of 14 will have to use more energy than a system with a SEER rating of 18. Those energy costs can really add up over the life of your system – up to several hundred dollars per year in savings. A higher efficiency system, because it uses less energy, is also a more environmentally friendly option.

As of January 1st, 2015 the minimum SEER rating for residential AC and Heat Pump Condensing Units is 14 SEER for the Southeastern United States. Manufacturers will not be able to produce 13 SEER equipment after December 31st, 2014. Distributors will have 18 months to sell existing 13 SEER product. Equipment manufacturers will not be able to manufacture “DRY 22” equipment unless 80% of their existing 13 SEER unit components can be used in a 14 SEER unit. Currently, there is no word of a 14 SEER “DRY 22” unit planned for production.
