What Is A Blower Door Test?

A blower door test calculates the rate of air changes per hour in a property, verifying that proper ventilation keeps air fresh and clean. Having too many air changes can waste energy because each new cycle demands the air be reheated or recooled, cutting overall efficiency. Excessive air changes often cause drafts, discomfort, and humidity-related issues such as condensation and mold growth inside the home. A blower door test in Haddonfield, NJ finds air leakage problems early, allowing better energy efficiency and enhanced indoor comfort for homeowners.

What Our Clients Say

How Is A Blower Door Test Conducted?

For blower door test in Haddonfield, NJ, all outside doors and windows are closed properly, and inside doors are kept open to balance air pressure throughout the space. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

When air is pulled from the home, outside air finds its way in through cracks and unsealed openings. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. These values are expressed as air changes per hour (ACH), a key measure of the home’s airtightness and its energy performance under NJ conditions.

What Is A Passing Blower Door Test Score?

In Haddonfield, NJ, energy efficiency standards for homes are based on the 2015 International Energy Conservation Code (IECC) or more recent updates approved by the jurisdiction. In many locations, a result of 3 air changes per hour or less is required to verify the home’s energy efficiency level. Reaching this target in your blower door test in Haddonfield, NJ helps maintain lower energy bills and fulfills local code obligations.

Why Do I Need A Blower Door Test?

Both NJ and local jurisdictions adopt the IECC energy code, making blower door test mandatory for new and renovated residential structures.

Select a proper air barrier such as Tyvek or Zip Sheathing and ensure every seam is thoroughly taped for airtight sealing.
Install insulation of the appropriate R-value and inspect to confirm it’s correctly fitted in all envelope areas.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Close gaps and penetrations between conditioned zones and unconditioned sections like attics, basements, and crawl spaces.
Local jurisdictions frequently publish compliance checklists — the Philadelphia version can be downloaded here.

Preparing for a Blower Door Test in Haddonfield, NJ

Before starting blower door test in Haddonfield, NJ, we turn off all heating, air conditioning, and exhaust fans in bathrooms and kitchens. Next, we check the home thoroughly to ensure all exterior openings — even those leading to garages or unfinished basements — are securely closed and within the thermal envelope. Once everything is sealed, we choose a centrally located exterior door and set up the blower door frame and fan. The fan then depressurizes the home to 50 Pascals, allowing us to measure airflow and leakage precisely. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. A thermal imager helps us identify air leakage points by revealing temperature shifts in walls, ceilings, and surfaces adjoining unconditioned areas. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. After sealing the identified leaks, we retest right away to confirm that the desired blower door score meets local energy performance standards in Haddonfield, NJ.
