Ductwork is essential to the operation of a traditional heating and cooling system. Old, dirty or otherwise failing ducts could mean that the cooled or heated air your unit produces isn’t properly disbursed around your home. Since this can mean increased energy costs, it’s worthwhile to periodically inspect the ducts to determine if it requires updating.
- Determine the age of the ducts – In most homes, ductwork was installed during a home’s construction and like other equipment throughout the house, it’s not expected to last forever. Even if the majority of your home is in great condition, the ducts might need attention.
- Inspect exposed ducts – Walk through your house and inspect the ductwork you can see, for example that positioned in attics. Check the condition of any tape or other sealant used to connect duct joints and look for evidence of rust, corrosion or streaks of dust, which indicate serious wear and tear possibly warranting replacement or repair.
- Check airflow – In each room of your home, check for reduced airflow or temperature differentials. You may do so by holding your hand or a piece of paper next to an air vent while your HVAC unit operates. Temperature differentials or low airflow indicate breaks in ductwork or improperly insulation.
- Schedule a blower test – If you think that the ducts in your home might need attention, contact an HVAC professional for a duct blower test. This test, which consists of testing duct pressure and airflow using a blower fan and airflow sensor, can determine if the ducts are leaking air. This final step can assist you in determining whether it’s time to repair or replace all or a portion of your ductwork.
