Is it normal for ductwork to make noise?

• <div><p>Ductwork will occasionally make noise as the metal experiences rapid temperature or air pressure changes. This is especially common when the furnace initially kicks on and pushes warm air into cold <a href="https://www.angi.com/articles/air-ducts.htm">air ducts</a>. However, this noise should not occur if the home is at a normal temperature most of the time. If you are hearing noises regularly, it may be a sign of a more serious problem.</p></div>

Q: Can I block the return air vents on the floor or ceiling?

• <div><p>Blocking or closing return air vents on the floor or ceiling will not save money on energy bills and could place additional stress on the HVAC system. Installers strategically place return vents to ensure the best flow of air throughout the entire system, so keeping them open and free from blockages is important. Figure out <a href="https://www.angi.com/articles/how-to-open-ceiling-air-vents.htm">how to open ceiling air vents</a> and return vents. Check them occasionally to ensure air can freely flow into them for maximum performance.</p></div>

Q: What is the main problem with flex ducts?

• <div><p>Flex ducts' main problem is also their main strength: their flexibility. Because the material they are made from has little structural support, they can start to sag or compress over time. They can also be more challenging to clean than sturdier ductwork. However, it&rsquo;s precisely this flexible nature that makes them a good solution for those who need a space-saving solution for their ductwork.</p></div>

Q: What happens if you don't follow an air duct cleaning schedule?

• <div><p>Failing to follow an air duct cleaning schedule can allow dust, allergens, and contaminants to accumulate. This can lead to poor indoor air quality and potential respiratory problems or allergies for occupants. Mold and mildew can develop in the ducts, posing serious health risks and creating unpleasant odors. Debris buildup can also restrict airflow, causing the HVAC system to work harder and reduce its efficiency.</p></div>

Q: How can you tell if an AC vent is open or closed?

• <div><p>There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.</p></div>
