Home Performance Testing is an in-home service with the goal of gathering information on your existing duct system and building envelope tightness.

The testing results will be explained in an individualized report, informing you of the current state of your existing duct system and building envelope tightness.

We offer comprehensive testing, reporting, and recommendations to improve the effectiveness and efficiency of your home.

Our service area stretches from south of Boston, MA, out to Concord, NH, and up to Portland, ME.

Duct Test

A duct test, also known as duct leakage test, measures the air tightness of an existing or new duct system. The duct test is the most common and useful way to analyze duct system performance.

Leakage to Outside Test

The leakage to outside test measures the amount of duct leakage to outside of the thermal envelope (attics, basements, or to the exterior of the house). This test is done while the blower door is running, so we recommend doing the blower door test alongside the leakage to outside test.

Blower Door Test

The blower door test measures the building envelopes airtightness and is used to locate the areas that air leakage occurs. While the blower door is running, the tester can move through the house and look for high leakage points and determine the best way to seal these areas.
