Ensure your home is sealed properly and energy-efficient with quality blower door test in Spring City, PA. Our certified professionals work with homeowners, builders, and contractors to uncover hidden air leaks and guarantee compliance with PA energy codes.

What Is A Blower Door Test?

A blower door test quantifies how often indoor air is renewed through air changes per hour, helping maintain optimal ventilation. 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. Excessive ventilation can lead to unwanted drafts, air leakage discomfort, and potential mold, condensation, or moisture problems indoors. A blower door test in Spring City, PA locates leaks and inefficiencies quickly, allowing homeowners to enhance energy performance and create a cozier living space.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Spring City, PA, 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. 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 air out, outdoor air enters the house through cracks, openings, and unsealed areas. By employing a nanometer, we measure the variance between the fan’s pressure and the internal home pressure. The pressure data is turned into air changes per hour (ACH), a measure of how efficiently and tightly the home is sealed in PA.

What Is A Passing Blower Door Test Score?

Construction in Spring City, PA must comply with the 2015 International Energy Conservation Code (IECC) or updated versions recognized by local authorities. An acceptable blower door test result in most areas is 3 air changes per hour or less, demonstrating solid energy performance. Meeting this requirement during your blower door test in Spring City, PA helps reduce energy costs while keeping your home compliant with local building codes.

Preparing for a Blower Door Test in Spring City, PA

To properly prepare for blower door test in Spring City, PA, the HVAC system and all bathroom and kitchen fans are turned off. 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. We carry all necessary materials, including chalk, spray foam, and weatherstripping, to collaborate with homeowners or contractors on visible air leakage repairs during testing. After sealing the leaks, we can immediately run another test to verify that the desired blower door score meets the local efficiency standards for homes in Spring City, PA.

For contractors arranging blower door test in Spring City, PA, most homes with professional insulation can handle small air leakage issues during the test itself.
