Clean the vent covers, replace the air filters, and call in a pro for an inspection. </p></div>

Q: What is the most common cause of poor airflow in a duct system?

• <div><p>For most homes, the common causes of poor airflow in a duct system are blockages, typically from dust, debris, or buildup. Other factors include leaky or disconnected ducts, improper duct sizing, and clogged air filters. These issues restrict airflow, reducing HVAC efficiency.</p></div>

Q: Are HVAC dampers necessary?

• <div><p>You do need dampers in your HVAC system, but they do help to regulate airflow and give you better control of the temperature in each room of your home. Most HVAC systems will have dampers installed, but this isn't always the case. If you don&rsquo;t have designated zones in your home, you&rsquo;ll likely still have valve control dampers on your supply vents for manual control.</p></div>

Q: Is cleaning air ducts really worth it?

• <div><p>Air duct cleaning hasn&rsquo;t been proven to prevent health issues, but it may help reduce contaminants in your home, which is especially important if you or a household member has asthma or allergies. Air duct cleaning is worth it if you have mold growth, pest infestations, or visible debris blowing from the air vents.</p></div>
