Can I close vents to deflect air?

Q: What are the health risks associated with musty smells?

• <div><p>Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.</p></div>

Q: How do I know if my ductwork needs to be cleaned?

• <div><p>Signs your ductwork needs cleaning include visible dust buildup, musty odors, increased allergy symptoms, and reduced airflow. If you see dust blowing from vents, find mold inside ducts, or notice a spike in your energy bills, it&rsquo;s time for a professional inspection and cleaning to improve air quality and efficiency.</p></div>

Q: What happens if you don’t clean your house regularly?

• <div><p>Not cleaning your house on a regular basis can lead to elevated allergen levels, pest problems, mold growth, damaged belongings, and parts of your home falling into disrepair. Consistent cleaning prevents problems that can lead to illness and ensures you&rsquo;re aware of the condition of everything in your home so you can maintain and repair things as needed.</p></div>
