Common Obstructions Affecting Cincinnati Duct Work


Homeowners in the Cincinnati area may experience many common obstructions in their ductwork. There are many ways you can stop these obstructions from happening and lowering your energy consumption. With clear ductwork, you will directly improve the efficiency of your HVAC unit and prevent any future HVAC repairs from occurring.

Air Filters

The number one reason for obstructions in your ductwork is a dirty or clogged air filter. A dirty air filter can cause other issues besides clogged ductwork, such as allergies and respiratory issues, which can be triggered due to poor indoor air quality. Air filters can also get sucked into your ductwork when not installed properly, which is a huge fire hazard if it gets near your blower assembly fan.

Ductwork Leaks

Leaky ducts can be a major reason for a ductwork obstruction. There are two ways for leaks to happen inside your ducts. The first is due to incorrect installation of your system, which makes the duct sections begin to pull apart. The second way for your ducts to leak is when the ducts are old and haven’t been sealed recently. If your ductwork is leaking it can cause air to not circulate efficiently throughout your home.

Insulation Obstructions

Some ductwork has insulation on the inside of them, which can come loose and fall into the ductwork. You also can have exterior insulation and debris settle inside your ductworks due to leaky ducts.

Flex Ducts

Flex ducts are more common in newer HVAC systems due to their efficiency and easy installation. Even though there are benefits to flex ducts, they are more apt to dent or collapse. Dents and collapses lead to obstructions in your ductwork quickly.

Stuck Dampers

If your HVAC unit runs with a zoning system, the dampers in your ductwork can malfunction. They may become stuck in a closed position, which obstructs the airflow inside your home greatly.
