Do whole-house humidifiers cause mold in ducts?

• <div><p>Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.</p></div>

Q: Is mold around air vents common?

• <div><p>It is common for mold to grow around air vents, especially in areas with high humidity or moisture problems. These vents provide a perfect environment for mold to thrive due to the condensation caused by the meeting of warm and cool air. Mold growth can be accelerated by the presence of dust and debris around the vents. Regular maintenance, proper ventilation, and addressing any water leaks or excess humidity can prevent the growth of mold around air vents.</p></div>

Q: Why are there so many air duct cleaning scams?

• <div><p>Air duct cleaning scams are, unfortunately, so common because the industry is largely unregulated, and technicians don&rsquo;t need to hold licenses in most states. It&rsquo;s also easy for scammers to use scare tactics to claim that your indoor air is potentially unsafe, which makes the service an easy sell. Finally, most homeowners don&rsquo;t have access to their hidden HVAC ducts and can&rsquo;t check on issues themselves, so it&rsquo;s easy to claim that there&rsquo;s mold or debris build-up in there and have it go unchecked.</p></div>

Q: Does cleaning air ducts really make a difference?

• <div><p>Clean air ducts ensure proper airflow throughout your household. They can also remove any built-up dust particles and make the air in your home that much cleaner. Lastly, cleaning your air ducts will help your overall energy cost and ensure your HVAC system works for years to come.</p></div>

Q: Does a basement need ventilation to reduce humidity?

• <div><p>Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.</p></div>
