Get expert advice, take steps toward energy efficiency with assessment.

Schedule an energy assessment and start saving

Increase your home’s heating and cooling efficiency—and save money while you’re at it—with our Home Transformer program.

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

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

And the assessment and report are both 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 so we can better plan a trip to your area.

Your free energy assessment includes:

  • Blower door test: determines your home’s airtightness.
  • 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.
