Important to Know

  • Existing homes only. Rebates are only available for existing homes. New construction homes do not qualify. 
  • Limited funds. Rebates are limited, not guaranteed and may be terminated without prior notice. Residential rebates are capped at $5,000 annually per customer account.
  • Rebate check time frame. If all program requirements are met, a rebate check is generally mailed within 8-10 weeks, unless your application is selected for inspection, which may take additional time. Incomplete applications will not be processed.
  • Keep copies. Keep a copy of your completed application with required documentation (including receipts, invoices, etc.) for your records.
  • Self-installation. Customers that self-install products do not need to work with a contractor.
  • Contractor Installation. If using a contractor to replace a heating ventilation and air conditioning (HVAC) system or to install attic insulation, these projects must be completed by a contractor on IID’s Participating Contractor List, unless the customer is self-installing the product.
  • Rebate frequency. A customer may only receive a rebate for the same product once every five years.
  • NEM customers. Net energy metered (self-generating) customers rebate amount will be determined by the percentage of their total energy usage that is not offset by their photovoltaic system. For example, if only 25% of an NEM customer’s energy is supplied by IID their incentive is reduced to 25% of the rebate amount listed on the application.
  • Building permit requirements. Building permits are a requirement of your local jurisdiction (city, county, etc.) for certain projects, including the replacement of a heating, ventilation and air conditioning (HVAC) system. Failure to apply for a building permit, when one is required, can result in a fine from your local building department. Call your local building department for more information.
