Pearl River Community College

Once they discovered it was a duct leakage problem, they began sending people into the ductwork to attempt to seal it manually. This didn’t deliver the required leakage reduction, meaning there was still underlying leakage. There was not one obvious hole or repair – the ductwork was consistently leaking throughout the building. Many of the leaks could be seen from access doors, but technicians could not access them. This caused setbacks.

Pearl River had been trying to resolve this problem for the last 2-2 ½ years. After consulting a team for a full investigation, they determined the hard ceiling had been put up before the ductwork was installed and finished. Because of this, there were sections that had been improperly sealed as well as sections that had not been sealed at all.

TruSeal was tasked with identifying a solution that would solve the project’s problem once and for all. They suggested Aeroseal, and although it seemed like a miracle solution at first, the school was willing to try it. Both buildings had two air handling units for a total of four, and Aeroseal had the job of sealing all four systems. For each system, they completed multiple tests and seals.

Reed Woods, the project manager at TruSeal, detailed how Aeroseal addressed the challenges presented by the project. “Most of the leaking ductwork was inaccessible, but with Aeroseal, we were able to seal it from the inside.” Reed noted the ductwork was lined with 1” x 1 ½ pound fiberglass duct liner, which created concerns that this would hinder the Aeroseal process. However, those concerns were unfounded. The Aeroseal process proceeded and they were able to reach the desired leakage reduction.
