- Indoor air is typically 4-5x more polluted than outdoor air
- A typical duct system leaks 35% to the outdoors
- Homes produce more C02 emissions than autos and light trucks combined
- 25% reduction in U.S. home energy consumption = taking 1/2 of all passenger cars off the road
Home Energy Audit Summary
The following is an example of the diagnostic tests and procedure provided in a home energy audit. This summary is not exhaustive and more diagnostic tests may be required per the discretion of the auditor. By examining and measuring a wide range of systems throughout your home, AHE can accurately identify and prioritize your home’s opportunities for improvement. After testing your home thoroughly we can provide suggestions, education, and service options to help improve the health, efficiency and comfort of your home.
Diagnostic Tests
