What Is A Blower Door Test?

A blower door test provides accurate data on air changes per hour, showing how efficiently fresh air circulates through your space. When air changes occur too frequently, the heating or cooling system must work harder to stabilize temperatures, increasing energy use and lowering efficiency. Frequent air changes can cause drafts and discomfort from leaks, increasing the risk of indoor mold and condensation. A blower door test in Ridgewood, NJ identifies air leakage issues before they become serious, ensuring efficiency, comfort, and long-term durability.

What Our Clients Say

How Is A Blower Door Test Conducted?

For accurate blower door test in Ridgewood, NJ, technicians close all exterior openings and keep interior doors open to balance airflow throughout the house. Technicians install a fabric panel and adjustable aluminum frame into one central exterior door opening. A calibrated fan is connected to the frame, lowering the home’s internal pressure to 50 Pascals, roughly matching a 20 mph wind force.

When the fan pulls indoor air outward, fresh air from outside rushes in through leaks and weak spots. A nanometer is used to detect and compare the pressure created by the fan with the air pressure inside the structure. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

What Is A Passing Blower Door Test Score?

In Ridgewood, NJ, homes are designed to meet or exceed the 2015 International Energy Conservation Code (IECC) or the latest locally adopted standards. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. When your blower door test in Ridgewood, NJmeets this requirement, you benefit from reduced energy bills and code compliance.

Preparing for a Blower Door Test in Ridgewood, NJ

For blower door test in Ridgewood, NJ, preparation includes turning off all heating and air conditioning units, plus bathroom and kitchen exhaust fans. We then perform a detailed walkthrough to verify that all exterior windows and doors are tightly shut, including any that lead to spaces beyond the thermal envelope. After sealing the home, we install the blower door frame and fan in a central exterior doorway. The fan depressurizes the home to 50 Pascals to provide accurate airflow and leakage readings. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. With a thermal imager, we identify cold or warm spots in walls, ceilings, and other surfaces that reveal air leakage into unconditioned spaces. Carrying chalk, spray foam, and weatherstripping materials, we work directly with homeowners or contractors to resolve visible air leakage issues during the visit. After sealing, we can immediately retest to confirm whether the desired blower door score has been reached, ensuring your home complies with local energy efficiency standards in Ridgewood, NJ.
