Q: How often should the air ducts in your home be cleaned?

• <div><p>Air ducts should be cleaned every three to five years, though the frequency can vary based on factors such as household conditions and local environmental factors. For homes with pets, smokers, or high dust levels, more frequent cleanings every two to three years would be necessary to maintain optimal air quality. If you notice persistent odors, significant dust buildup, or signs of mold or rodent activity, schedule a cleaning sooner.</p></div>

Q: How do I know if my ducts need to be sealed?

• <div><p>There are a few things that you can look out for that indicate that you need duct sealing, but the two most critical ones are less comfortable air in your living space and increased utility bills. If you notice that you&rsquo;re paying more often for HVAC servicing and maintenance, that could suggest that you need duct sealing, as well, as leaks put added strain on your system. You may also notice musty odors in parts of your home, as leaks can lead to <a href="https://www.angi.com/articles/stop-condensation-on-air-vents.htm">condensation on your air ducts</a> that can promote mold growth behind your walls. </p></div>

Q: Should you leave the house during duct cleaning?

• <div><p>Most experts recommend leaving the house during a duct cleaning, especially if you have small kids or pets. The process is noisy and disruptive, and the house will be filled with specialized equipment. The technicians may also require seamless access to different areas of the home. Talk to your pros and ask them if you should take a short walk around the neighborhood while they work. </p></div>

Q: Is it bad if water gets in your vent?

• <div><p>If you notice water accumulating in your vent due to a roof or plumbing leak above your ductwork, it's essential to promptly identify the source of the leak and undertake any required repairs without delay. Such leaks have the potential to swiftly result in water damage within your home, ultimately leading to mold and mildew concerns.</p></div>
