Click for link to Comptroller's online site. Other rebates and incentives are also detailed.

Kickoff of the Texas Trade Up Appliance Rebate Program begins Monday, when Texas consumers can begin obtaining rebate forms for purchase of select ENERGY STAR appliances. Those rebates will apply to the purchase of energy efficient appliances to replace older appliances.
 
The program, administered by the State Comptroller's Office, offers an online reservation system and a toll-free phone number for consumers to sign up on a waiting list for any guaranteed rebates that are unused. However, getting on the waiting list does not guarantee a rebate. Consumers can save up to $1,200 on air-source heat pumps, up to $1,000 on central air conditioners and hundreds of dollars on refrigerators, freezers, clothes washers, dishwashers and hot water heaters.
 
Funding for the program is limited and only two appliance rebates will be issued per household. Registering will allow consumers to print or receive the application forms needed to mail in and receive rebates after qualified appliance purchases. Texas received approximately $23 million in stimulus funding for the program. To access the online reservation system and for more information, click here, or call toll free 877-780-3039.
