Transform your home!

Get expert advice and take steps toward energy efficiency with an assessment.

Home Transformer

Schedule an energy assessment and start saving

Increase your home’s heating and cooling efficiency—and save money—with our Home transformer program.

Thermal imaging
Thermal imaging reveals locations where your home is losing energy.

An energy expert will measure your home’s efficiency and evaluate your energy use, providing you with a report of efficiency recommendations.

Both the assessment and report are free!

How it works

We offer a limited number of Home transformer assessments per year and schedule groups by geographic area. We encourage customers to apply early in the year, so we can better plan a trip to your area. 

Your free energy assessment includes:

  • Blower door test: Determines your home’s air tightness.
  • Thermal-imaging analysis: Gauges the effectiveness of insulation.
  • Detailed report: Recommends ways to improve your home’s efficiency, and provides estimates of energy cost savings.

  • 8 LED lightbulbs
  • Outlet gaskets
  • Window caulking
  • Weather stripping
  • 1 low-flow showerhead
  • 2 faucet aerators
  • Pipe insulation
  • 1 advanced power strip
  • 1 door sweep
