Your HVAC system is crucial to your home comfort. There are some common above-ground duct problems to look out for and correct before they become larger ones. Leaking ducts and fiberglass fibers from duct board liner are two common problems experienced with overhead ductwork.
Unsealed joints and leaks in your above-ground ducting force your system to work harder and run longer to maintain optimal efficiency. The result is decreased system performance and an increased energy bill. And since your system is running more frequently, you’re also at an increased risk of a breakdown because of the additional strain on your system.
Many above ground air ducts are manufactured with a fiberglass insulation liner installed on the inside of the duct for insulation and sound reduction. The problem with this is that over time the fiberglass liner breaks down and fiberglass fibers get released into the air. This break down also causes dirt, dust and other debris to get caught in the insulation, making the liner impossible to thoroughly clean. As a result, as air flows through the ducts, the fiberglass fibers are released into the air you breathe.
