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>

Q: Is it possible to clean your own air ducts?

• <div><p>While homeowners can find <a href="https://www.angi.com/articles/duct-cleaning-equipment-pros-should-use.htm">DIY air duct cleaning tools</a>, full duct cleaning is not recommended due to the complexity and specialized equipment required for the job. You can perform basic maintenance tasks like changing filters and vacuuming vents, but you can&rsquo;t access all areas of the ductwork. It&rsquo;s also not safe for homeowners to try to use high-powered vacuums and handle potential contaminants like mold and dust. Hiring a certified air duct cleaning service is the best option for a comprehensive and safe cleaning.</p></div>

Q: How do you fix a weak AC airflow?

• <div><p>Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.</p></div>

Q: What are the signs of too much humidity in a room?

• <div><p>Excessive humidity in a room often manifests through visible signs like condensation on windows or walls, a musty or damp odor lingering in the air, peeling wallpaper or paint, and the presence of mold or mildew. Experiencing discomfort due to a consistently clammy or sticky feeling can also indicate high humidity levels.</p></div>
