Confirm your home’s energy performance and identify leaks through accurate blower door test in Ship Bottom, NJ. Our qualified technicians assist homeowners, builders, and contractors in detecting air leaks, optimizing comfort, and maintaining compliance with NJ energy codes.

What Is A Blower Door Test?

A blower door test determines the air changes per hour of a house or building, ensuring proper ventilation as old air cycles out and fresh air flows in. 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 Ship Bottom, 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?

To execute blower door test in Ship Bottom, NJ, exterior windows and doors are secured shut, while interior doors are left open to distribute air evenly. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. Technicians use a calibrated fan mounted on the frame to bring the home’s interior to 50 Pascals, approximating a 20 mph wind on the walls.

As the fan extracts air, exterior air begins entering the house through any unsealed spaces or cracks. A sensitive nanometer is used to monitor and compare the pressure difference between the blower fan and the home’s interior air. The data collected is translated into air changes per hour (ACH), showing the home’s airtightness and overall energy efficiency in NJ conditions.

Preparing for a Blower Door Test in Ship Bottom, NJ

To prepare for blower door test in Ship Bottom, NJ, we start by turning off the heating and cooling system, along with all bathroom fans and kitchen exhaust fans. We perform a quick check throughout the property, making sure all exterior windows and doors — including those to unfinished or non-conditioned areas — are sealed, maintaining 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. When the house is depressurized, outside air begins entering faster, exposing hidden leaks more effectively. With a thermal imager, we identify issues by locating temperature differences across walls, ceilings, and surfaces leading to unconditioned areas. Our team provides on-site repair using chalk, spray foam, and weatherstripping, working with homeowners or contractors to fix visible air leakage problems. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Ship Bottom, NJ efficiency codes.
