A dirty filter here, a stuck damper there — pretty soon your utility bills are on a nonstop upward trend. Ductwork obstructions are a headache. They increase energy consumption, directly impact whole-house comfort and can contribute to significant HVAC issues and repairs. Have your ductwork inspected to determine if any of these common issues are causing problems with your HVAC system.
Dirty and clogged filters are the leading cause of HVAC system failures. For this reason, it's usually the first place an HVAC technician will look if he or she suspects ductwork obstructions are causing your heating or cooling issues. Dirty filters will also compromise your indoor air quality, which can trigger allergies and other respiratory issues. Make sure you check the air filter monthly and change it as soon as dirt or dust is visible.
On occasion, filters can be sucked into the ductwork, forming a significant obstruction. This can also be a fire hazard if it migrates into the blower assembly fan.
Many newer systems use flex ducts because they're cost efficient and easier to install. However, they're also more prone to dents and collapse than their hard duct counterparts, which makes them more susceptible to duct obstructions.
There are two primary causes of leaky ducts: poor installation and outdated duct sealing products. If your system was poorly installed, the duct sections can begin to separate, or they may have never been adequately sealed together in the first place. If your ducts are older and you haven't had them resealed, old mastic tape or caulk can erode. These leaks prevent air from circulating efficiently.
Some ducts have insulation on the interior that can separate away and collapse into the ductwork. In other instances, leaky ducts can allow exterior insulation and debris to settle inside.
If you have a zoning system, the dampers in the ductwork can become stiff, causing them to get stuck in the almost closed or closed position. This is a major obstruction and will compromise your home's comfort.
