Window Air Conditioners

Receive a $50 rebate from Austin Energy to buy a new ENERGY STAR® qualified window air conditioner.

  • Description
  • Incentive
  • Eligibility
  • How to Apply

Austin Energy offers a $50 rebate when you buy a new, qualifying ENERGY STAR window air conditioner. ENERGY STAR window air conditioners use up to 15% less energy than conventional models. Timers on the unit let you adjust temperature settings for comfort and savings.

Be sure you choose the right size based on the size of your room. A unit that is too large for your room can make your air-conditioned space damp and uncomfortable. The benefits of getting the right-sized unit include: 

  • Getting the best value
  • Reduced energy costs
  • Removing humidity properly
