Why Buy an Energy-Efficient Central Air Conditioner?
To realize the most savings, invest in an energy-efficient central air conditioning system for your home. Even better, purchase an ENERGY STAR qualified model, which is about 20% more efficient than standard models. Heat pump and central air conditioner efficiency is often expressed in terms of the Energy Efficiency Ratio (EER) and/or Seasonal Energy Efficiency Ratio (SEER), which are defined as the cooling effect (in Btu) divided by the power use (in watts) for the peak day (EER), or by the seasonal average day (SEER). ENERGY STAR qualified models are more energy-efficient due to higher SEER or EER. • Cut energy costs in half. If your air conditioner was made in the 1970s, you are using 30 to 50% more energy than today’s best air conditioners to produce the same amount of cooling. Replacing an old central air conditioner that has a SEER of 6 with a new energy-efficient unit that has a SEER of 12 or better may cut your air conditioning costs in half.
