Window Air Conditioner Trade-Up

Earn a $50 rebate for purchasing a qualified window air conditioner (AC) and trading in your old, working window ac or portable air conditioner unit for recycling! To qualify, your unit must have an Energy Efficiency Ratio (EER) of 11.2 or higher. You could save about $67* per year on your electric bill, plus an energy-efficient AC uses 15% less energy than conventional models.

Due to the closure of appliance recycling facilities on the Big Island, the $50 Window Air Conditioner Trade-Up rebate for Hawaii County are suspended until further notice. Hawaii Energy is actively seeking alternative solutions and hope we can continue to provide this rebate to Hawaii Island participants in the near future. Please call 1-877-231-8222 if you have any questions.

*Estimated savings based on $0.34/kWh. Savings may vary depending on make, model and usage of your window AC.

Some Simple Buying Tips:

  1. Look on the unit's box for Energy Efficiency Ratio (EER) of 11.2 or higher. The higher the rating means the unit is more energy-efficient.
  2. Make sure you are buying the right size Window AC for your needs. To learn more, visit http://energy.gov/energysaver/articles/room-air-conditioners.
