If your forced air heating and cooling system is the heart of home comfort, then consider the ductwork running throughout your home as the lungs of the system, breathing in air that needs heated or cooled and breathing out filtered, conditioned air into each room. You may begin to notice your system isn’t working as well as expected, with inefficient airflow, temperature fluctuations or decreased air quality. This could indicate problems with aging ductwork and should be addressed as quickly as possible before bigger problems arise, such as increased utility bills or maintenance costs to repair or replace overworked equipment.
Inspect the Ductwork
To help you decide if air sealing the ductwork is an option or if replacement would be the best solution, visually inspect any exposed ductwork, keeping in mind that enclosed areas will have deteriorated in a similar manner but cannot be repaired either easily or cost-effectively.
- Determine the age of the ductwork. Original ductwork may have been installed cheaply and inefficiently. If additional HVAC equipment has since been added, the aging ductwork might not be sufficient for your home’s needs, meaning a new duct design is warranted.
- Look at exposed ductwork, noting how sections are connected. Has the sealant deteriorated? You might see streaks of dust showing at seams which indicate air leaks or perhaps rust or corrosion where moisture has escaped.
- Poor airflow in a room could indicate a section of broken or collapsed ducts. Temperature fluctuations are indicative of air leaks or possibly poorly-insulated ductwork. You can schedule a duct blower test with your HVAC contractor to measure the amount of air pressure needed to maintain a standard level. Your contractor can calculate the amount of air leakage based on total airflow through the system.
