An efficiency assessment at your home can help identify inefficiencies in your home and spell out benefits that result from efficiency upgrades. You also will be paired with an expert energy advisor who helps review project bids and plan future projects, making the process seamless.

Assessments are optional for HVAC rebates. Assessments are required for larger rebate projects that require installation by an Efficiency Works listed service provider, including insulation, air sealing and window rebates.

Efficiency Works also offers instant rebates to qualified customers on efficiency products, such as LED lighting, smart thermostats and more at the Efficiency Works Store. Efficiency Works also offers post-purchase rebates for specific efficiency products. Learn more about qualifying products here.

An Efficiency Works energy advisor comes to your home on the scheduled day and time. The assessment takes between 2-4 hours to complete. The advisor performs an overall inspection of your home, including building diagnostics such as:

  • A blower door test to measure air leakage in and out of the home
  • Infrared imaging to see deficiencies in the building’s thermal envelope
  • A window test to evaluate the efficiency of the window glazing
  • Visual inspections of the home’s exterior, attic, crawl space and basement
  • Identifying potential health and safety concerns such as whole house ventilation needs and testing for carbon monoxide issues
  • NOT included in your inspection:
    • Interior and exterior water use analysis (including sprinklers)
    • Solar analysis
    • Testing for asbestos, lead, or mold (your advisor will notify you of potential issues and recommend testing if applicable)

Performance-based rebates must be inspected following installation to ensure that they meet performance specifications outlined in Appendix A of the program participant guide to ensure predicted energy savings will occur.

The following Efficiency Works rebates are performance based:

  • Air conditioners
  • Heat pumps
  • Ductless mini splits
  • Air sealing measures
  • Attic insulation

After your scheduled installation, your Efficiency Works service provider will test to ensure that your upgrade meets performance specifications required to receive a rebate. These tests may happen during installation or your service provider will schedule a follow-up appointment for testing. If the upgrades do not meet the Efficiency Works performance metrics, additional work may be required before a rebate is issued to the customer.

Yes, for larger rebate projects (e.g. HVAC, windows, insulation/air sealing). To ensure strict quality control standards required by the Efficiency Works Homes program, we require certain rebated equipment be installed by a listed service provider to receive a rebate, even if the work passes a city inspection.
