Evaluate your home’s air leakage and achieve energy compliance with precise blower door test in Middletown, DE. Our trained team assists homeowners, builders, and contractors by detecting hidden air leaks, boosting comfort, and meeting DE energy regulations.

What Is A Blower Door Test?

A blower door test helps calculate air changes per hour in your property. This natural air exchange process refreshes the indoor environment with new air. When the air changes too often, energy efficiency drops since the system must continuously reheat or recool the air inside. When too much air is exchanged, it can cause drafts, reduce comfort, and create conditions for moisture buildup and mold. A blower door test in Middletown, DE allows early detection of air leaks, helping homeowners and builders boost efficiency and maintain a comfortable, durable living environment.

What Our Clients Say

How Is A Blower Door Test Conducted?

To carry out blower door test in Middletown, DE, exterior doors and windows are fully closed, and interior doors are left open for even air distribution in the home. One central exterior entry is selected, and an aluminum frame with a flexible fabric panel is installed securely. A calibrated fan is fitted into the frame and depressurizes the home to 50 Pascals, mimicking the pressure caused by a 20 mph wind.

As the fan operates, it forces outside air to penetrate the home through gaps, leaks, and openings. A sensitive nanometer helps us measure and compare the pressure created by the fan with the interior air pressure. These readings produce the air changes per hour (ACH) value, indicating both the home’s airtightness and efficiency within the DE climate.

What Is A Passing Blower Door Test Score?

Homes throughout Middletown, DE are required to satisfy the 2015 International Energy Conservation Code (IECC) or the most current version enforced by local regulators. Generally, a blower door test result of 3 air changes per hour or less is considered acceptable, ensuring proper energy performance. Complying with this benchmark during a blower door test in Middletown, DE helps cut energy expenses and meet local building regulations.

Use insulation with the right R-value and confirm it is properly installed throughout the building envelope.
Seal all penetrations in exterior walls using caulk or spray foam.
Ensure doors and windows are properly installed, caulked, and weather-sealed.
Ensure complete sealing of all openings between conditioned rooms and unconditioned areas like basements, attics, and crawl spaces.

Preparing for a Blower Door Test in Middletown, DE

To ensure accuracy during blower door test in Middletown, DE, we begin by switching off the HVAC system and all exhaust fans in the home. Next, we carefully walk through the property to make sure all exterior openings — including those to basements, garages, or areas outside the thermal envelope — are closed properly. Once all openings are sealed, we place the blower door frame and fan in a central exterior door. The fan then lowers the pressure to 50 Pascals for precise leakage measurement. Once depressurization is achieved, the inflow of outside air intensifies, making air leaks easier to find and fix. Using a thermal imager, we locate inefficient areas by tracking temperature changes in walls, ceilings, and surfaces bordering unconditioned spaces. With chalk, spray foam, and weatherstripping materials on hand, we partner with homeowners and contractors to repair visible air leakage issues on the spot. Once air leaks are sealed, we quickly retest to determine if the desired blower door score has been achieved, ensuring your home meets Middletown, DE efficiency codes.
