Can I close vents to deflect air?

• <div><p>No, because closing air vents could damage your HVAC system. Closing a vent will only keep the air in the duct, not redirect it to a room or zone where you’d prefer it to be. That air will become trapped within your ductwork, creating a buildup of pressure that can damage the ducts and cause leaks. </p></div>

How often do HVAC systems need maintenance?

• <div><p>You should have your HVAC serviced at least <b>once per year</b>. A HVAC pro can perform maintenance twice a year if your unit is older or has many issues. You can expect to pay between <b>$100 and $550</b> for <a href="https://www.angi.com/articles/ac-service-cost.htm">HVAC maintenance</a>, which includes a thorough tune-up, routine service, proactive and reactive maintenance, and emergency maintenance services. </p></div>

Q: How do I get water out of my air vents?

• <div><p>To get water out of AC vents, first identify the source of the water. Check other air vents in your home for signs of moisture. If you can&rsquo;t find any, look around the room for anything that might have seeped water in like an overwatered plant or a spill. Meanwhile, if you notice more than one air vent wet in other areas of your home, it&rsquo;s more than likely an issue with your insulation, roof, or air conditioner. Start by hiring an HVAC technician who can trace the source of the leak for you.</p></div>

Q: How often should return vents be cleaned?

• <div><p>Return air vents should be cleaned at least every two to five years. However, they should be cleaned immediately if you notice debris forming on them, mold growth in the ductwork, signs of pest infestation, or noticeably more dust on your furniture.</p></div>

Q: Can dirty air ducts restrict airflow?

• <div><p>Yes, dirty air ducts restrict airflow, reducing your HVAC's efficiency. This forces your system to work harder, increasing energy costs and wear and tear on your HVAC. Reduced airflow leads to uneven heating or cooling, seriously reduced indoor air quality, and can potentially trigger allergies or respiratory issues.</p></div>
