We provide essential air tightness testing, including blower door and duct leakage testing, as well as Aeroseal duct sealing. Our tests address the International Energy Conservation Code (IECC), which is incorporated into state requirements. Our sealing services lead to lower energy bills, higher efficiency, healthier air quality and more even indoor temperatures.

Blower Door Test

When we conduct a blower door test, a blower door fan is placed in the main entry doorway to depressurize the house/suck out air from the interior. This process will cause outside air to be drawn into the house through leakage points and demonstrate its air tightness. Lower air leakage leads to better energy efficiency.

Duct Blaster Test

A duct leakage performance test, or duct blaster test, involves pressurizing the duct system with a calibrated fan and simultaneously measuring the air flow through the fan and its effect on the pressure within the duct system. The tighter the duct system, the less air is needed from the fan to create a change in duct system pressure. Total duct leakage indicates the system’s air tightness. Leakage decreases energy efficiency and can result in home air quality issues.

Aeroseal Home Duct Sealing

Aeroseal is an innovative technology that efficiently seals duct leaks in a straightforward process. A pretest measures how much duct leakage a system is experiencing. Non-toxic, UL-tested and approved Aeroseal sealant is injected into the duct system to seal these leaks. As the sealant exits ductwork through the leaks, it begins to collect on the edge of gaps until leaks are completely sealed. Aeroseal can seal up to 5/8ths of an inch gap or hole. A computer-generated analysis summarizes our clients’ duct leakage reduction and we provide a certificate summarizing the results.
