Cooling efficiency for your air conditioner is measured by its SEER (Seasonal Energy Efficiency Ratio) rating. SEER tells you how efficiently your unit uses electricity. The higher the SEER rating, the less electrical cost you will incur to cool your home. Units installed after 1992 were required to be at least 10 SEER. Now, as of January, 2006 units are required to be at least 13 SEER. In January, 2023 the US Department of Energy has mandated all ACs installed in the northern US (including Ohio) will be required to be at least 14 SEER.
Effective January, 2010 all manufacturers were mandated to no longer manufacture R-22 based air conditioners or heat pumps. R-22 is the refrigerant (coolant) that most all air conditioners have operated with over the last fifty years. This refrigerant, however, has been deemed environmentally unfriendly. R-410A - which is environmentally friendly – is now the industry's refrigerant of choice. All manufacturers air conditioners & heat pumps now are offered only in the environmentally friendly R-410A refrigerant.
