Typical Attic Issues in NJ Homes

Air Handler
Air Handler & Ducts

We are currently assessing a residence in Freehold Township, NJ, encountering common issues found in attics on a regular basis. Our focus is on the Air Handler, where we observe standard flexible trunks connecting to it and metal ducts linked to the air handler. Our inspection will specifically target the metal ducts to check for air leakage and ensure that the flexible ducts are securely connected, with proper insulation.

Upon examining the fiberglass insulation, we notice a buildup of dirt, indicating a potential lack of proper air sealing in the attic. Upon closer inspection, we identify a blower fan that appears to be incorrectly connected, with mastic tape being used as part of the exhaust system. This misconfiguration is causing exhaust or moisture leakage back into the attic, posing a risk of moisture accumulation and potential damage to the wood or roof rafters.

Furthermore, our evaluation reveals that the mastic tape on the metal duct is also allowing conditioned air to leak back into the attic. Finally, when examining the interior attic wall or adjoining wall, we observe a lack of insulation insulating the conditioned room. This oversight results in conditioned air leakage into the attic, resulting in elevated energy bills and an uncomfortable living environment for the homeowners.

Various solutions are available depending on the specific application or issues at hand. If the air handler is faulty, it can be replaced. Metal ducts can be sealed using mastic tape, or if needed, ducts can be encapsulated with SilverGlo foam boards. Flexible ducts can be reconnected, and their connections can be air-sealed to eliminate leaks. Additionally, flexible ducts can be reinsulated, and improper exhausts can be replaced with suitable exhaust fans, ensuring proper connections while air-sealing them. SilverGlo foam boards can be installed on adjoining walls and air-sealed to prevent conditioned air from leaking into the attic. Finally, the attic floors can be air-sealed with ZypFoam sealant, and TruSoft cellulose insulation can be blown in, providing the homeowner with a more comfortable and energy-efficient home.
