Your HVAC contractor will still be required to perform quality checks. The measurements will be recorded directly on the rebate application form.
*May be used instead of an HVAC SAVE® test for equipment installed between September 15, 2018 and December 31, 2018.
Thermal Envelope Improvements
You must use a professional contractor and you must receive pre-approval from CFU for thermal envelope improvements (exceptions noted below). CFU will pay incentives on residential attic insulation provided that the existing insulation level is less than R-30. Homes with R-30 or higher insulation levels will see little return on the investment in additional attic insulation. Rebates applications may be submitted for projects that increase the attic insulation up to a maximum of R-49.
You can use any licensed contractor to qualify for CFU's air sealing and insulation incentives. This list of contractors have provided proof of insurance and certification to CFU.

Please contact CFU Energy Services at 319-266-1761 for more information about insulation project rebates. Not all insulation projects will qualify for incentives. NOTE: CFU’s lifetime rebate limits per address are 60% up to $1,000 ($200 for customers with propane heat) for each of two separate categories: sidewall, and foundation. Once CFU has rebated $1,000 in any of these categories (or $200 in air sealing/caulking/weather-stripping costs), all additional requests for reimbursement in that category will be denied. Some exceptions may apply; contact CFU Energy Services at 319-266-1761.
