One aspect that has an outsized impact on your home environment is your ductwork. These passages distribute warm air from your furnace and cooled air from your A/C, but they unfortunately can be circulating other things, too. If your ducts haven’t been cleaned in a while, they likely have dust, debris and potentially mold and other unpleasant things.
This can be a big problem for your household. Clogged and dirty ductwork can make your house less clean and your loved ones less healthy. These airborne pollutants exacerbate asthma and allergy symptoms, plus make seasonal illnesses more likely. Clogged ductwork also restricts airflow to and from your HVAC equipment. That means your systems will need to cycle more often, using more energy. It also means that they’re more likely to have service issues because of accumulated debris and increased wear.
Here are five of the top symptoms that your ductwork needs cleaning right away.
Changing your HVAC air filter on a regular maintenance schedule is good practice, but if you find yourself constantly swapping filters, your ductwork is likely the culprit. Heavily clogged ducts force debris back through the system at an accelerated rate, overwhelming filters far ahead of schedule. Restoring clean airflow is essential to a healthy indoor environment.
Walk through your home and pay attention to the airflow coming from each vent. If certain rooms feel noticeably weaker than others, a blockage somewhere in the duct system is the most probable cause. Make note of which rooms seem affected and share that information with our technician. It helps narrow down the problem quickly.
Most households need to dust flat surfaces every few weeks. If you’re dusting far more frequently than that — only to find surfaces coated again within a day or two — your ducts are almost certainly redistributing dust throughout the home every time the system runs.
Your ductwork should operate quietly, with the exception of the motor pushing air through it. Rattling, banging or other unusual sounds warrant a prompt call to a professional, as ignoring them can lead to more costly damage down the road.
Odors deserve equal attention. Musty or mildewy smells coming from your vents often point to moisture accumulation, mold or mildew growth somewhere in the duct system, a serious concern for indoor air quality. An unpleasant, more pungent odor could indicate something worse: a pest that found its way into your ductwork and didn’t find its way back out. Either situation calls for professional inspection without delay.
A steady, unexplained rise in your energy costs is often a sign that your HVAC system is working harder than it should to maintain your set temperature. Dust and debris buildup in the ductwork restricts airflow, forcing the system to run longer and consume more energy. If your bills are creeping up and you can’t attribute it to unusual usage, your ducts may be overdue for cleaning.
