Hancock-Wood annually offers a $900 rebate on new or replacement geothermal system installations until funding is depleted. 

Also receive a four-month (June - Sept.) $5.50 bill credit whether the switch is activated or not. This is part of our program to help control the demand for electricity and continue to stabilize rates.

Installation of a Radio-Controlled Switch is required for rebate; however, not all systems are able to accept having a switch installed. If your system does not accept a switch, this will only affect $100 of the entire rebate. Please call us so we can schedule an evaluation of your system.

How do I participate?

  1. Contact Us before you purchase your system to inquire whether or not the system you are considering will work with our switches. Not all systems are conducive to having a switch installed, so please inquire whether or not the system you are considering will work with our switches before purchase.
