What Is A Blower Door Test?

A blower door test measures the building’s air changes per hour, helping ensure indoor air is consistently refreshed. An excessive rate of air changes can be inefficient because each time the air is replaced, it must be reheated or recooled, raising energy costs. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in North Hanover, NJ helps homeowners and builders find and fix leaks promptly, boosting energy efficiency and indoor comfort for years to come.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in North Hanover, NJ, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. A central exterior door is picked, where the technician fits an adjustable aluminum frame and fabric panel for airtight testing. The mounted calibrated fan depressurizes the building to 50 Pascals, a condition similar to the effect of a 20 mph wind.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer precisely gauges the pressure applied by the fan in relation to the home’s internal air pressure. These results are transformed into air changes per hour (ACH), an indicator of the home’s airtightness and its efficiency in NJ conditions.

Preparing for a Blower Door Test in North Hanover, NJ

To ensure accuracy during blower door test in North Hanover, NJ, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we do a complete walkthrough to ensure all exterior doors and windows are sealed — including those opening to garages, unfinished basements, or areas beyond the thermal envelope. Once all doors and windows are sealed, we set up the blower door system in a centrally located exterior door and reduce air pressure to 50 Pascals to evaluate leakage. Once the home is depressurized, outside air starts infiltrating more forcefully, making it easier to spot air leaks. With the help of a thermal imager, we can uncover leaks and weak spots by spotting temperature differences across walls, ceilings, and surfaces near unconditioned spaces. Our team brings chalk, spray foam, and weatherstripping supplies to every job, enabling us to collaborate with homeowners or contractors to seal visible air leakage areas immediately. After completing the sealing process, we can retest right away to check if the desired blower door score has been obtained, confirming compliance with North Hanover, NJ efficiency standards.
