Fort Collins Utilities (FCU) provides rebates for customers living in existing single-family homes who pursue energy efficiency projects. Either the Efficiency Audit or Efficiency Audit Plus is a required prerequisite for all efficiency rebates. Specific rebate amounts may vary based upon existing home conditions and whether the home is heated with gas or electric. Rebates are available for insulation, heat pumps, air conditioners, windows, evaporative coolers, water heaters, furnaces, and boilers. To qualify for a rebate the new efficiency improvements must be installed by a contractor on Fort Collins Utilities participating contractor list. All efficiency standards must be met in order to receive incentives. See program web site for complete information regarding applications, documentation, procedures, and efficiency standards. Interested customers should contact FCU for further information on this program.
