What Is a Home Energy Audit?
A home energy audit is a comprehensive assessment of how energy moves through your home — where it's being used efficiently and where it's leaking out. A professional energy audit goes far beyond changing light bulbs and checking thermostat settings. It uses diagnostic tools like blower door testing and infrared thermal imaging to identify the specific locations and magnitudes of energy loss in your home's building envelope.
By understanding your home's unique energy characteristics, you can make targeted improvements that deliver real, measurable savings. Rather than guessing which upgrades will help most, diagnostic testing shows you exactly where your money should go.
What Our Energy Audit Includes
Blower door test — measures total air leakage in cubic feet per minute; establishes a baseline for your home's tightness
Thermal imaging (infrared camera) — visually identifies insulation gaps, air leaks, moisture intrusion, and thermal bridges throughout the home
Insulation assessment — measure existing insulation levels in attic, walls, crawl space, and basement against current DOE recommendations for Missouri
HVAC system review — assess ductwork leakage, filter condition, and whether the system is properly sized for the home
Moisture assessment — identify areas of condensation, high humidity, or active water intrusion
Full written report — prioritized list of recommended improvements with estimated costs and expected savings
Utility bill analysis — compare your usage against similar homes in the St. Louis area
Why Get an Energy Audit Before Insulating?
Many homeowners jump straight to adding insulation, only to find that their energy bills barely move because the real problem was air leakage, duct losses, or moisture that prevented the insulation from performing. An energy audit ensures every dollar you invest in insulation and air sealing goes to the highest-impact improvements first.
Think of an energy audit as the diagnostic before the prescription. You wouldn't add insulation blindly any more than a doctor would prescribe medication without running tests first.
The Tools We Use
Blower Door Test Equipment (ASTM E779 Compliant)
Creates a controlled pressure difference to measure air leakage and identify the specific locations where air escapes the home.
FLIR Thermal Imaging Cameras
Shows temperature differences across walls, windows, and ceilings to reveal insulation gaps and air leaks that are invisible to the naked eye.
Combustion Safety Testing Equipment
Ensures that gas appliances are operating safely and not venting dangerous exhaust into the home.
Duct Blaster for Ductwork Leakage Testing
Measures HVAC ductwork leakage, which often accounts for 20-30% of conditioned air loss in homes with ducts in attics or crawl spaces.
