Energy efficiency testing across New Jersey
Building Performance Analysis provides professional building inspections focused on energy efficiency and indoor comfort. Our services include residential blower door testing, blower door inspection, and duct leakage testing.
We measure the airtightness of homes and commercial properties. The results show where air escapes, so you can fix the leaks that drive up energy bills and cause discomfort.
Duct leakage testing shows how much air your ducts lose, which affects how well your HVAC system heats and cools. Whether you need a full blower door inspection or a duct test, we deliver accurate results and clear recommendations.
