What Is a BPI Home Energy Audit?
A home energy audit is a top-to-bottom diagnostic of how your house uses (and loses) energy. Unlike a quick walk-through inspection, a true audit uses calibrated diagnostic equipment to measure actual performance.
SMW's audits follow Building Performance Institute (BPI) standards — the national gold standard for whole-home performance assessment — and are performed by BPI-certified professionals. That means consistent, science-based results you can trust to guide real improvements.
What's Included in Your Audit
Every audit follows the full BPI assessment protocol.
Blower Door Test
A calibrated fan depressurizes your home so we can measure exactly how much air is leaking through walls, windows, and the building envelope.
Duct Leakage Testing
We pressurize your duct system to find hidden leaks that waste cooled air into attics and crawlspaces, often the single biggest source of energy loss.
Thermal Imaging
Infrared cameras reveal missing insulation, thermal bridges, and air leaks that the naked eye cannot see.
Insulation Evaluation
We inspect attic, wall, and crawlspace insulation for coverage, depth, and condition, comparing it to current Arizona efficiency standards.
HVAC Performance Check
Our NATE-certified technicians measure airflow, refrigerant charge, and system efficiency to confirm your equipment is operating as designed.
Combustion Safety Testing
For homes with gas appliances, we test for carbon monoxide, draft issues, and gas leaks to make sure your family is safe.
What Your Audit Report Looks Like
Below is a real audit we recently completed on a 2,231 sq ft Phoenix home. Customer information has been removed — only the technical findings and thermal imaging are shown.
