Can I close vents to deflect air?

• <div><p>No, because closing air vents could damage your HVAC system. Closing a vent will only keep the air in the duct, not redirect it to a room or zone where you’d prefer it to be. That air will become trapped within your ductwork, creating a buildup of pressure that can damage the ducts and cause leaks. </p></div>

How much does HVAC maintenance cost?

• <div><p>The cost depends on the exact task. Overall, AC tuneups cost $70 to $150 on average. Filter replacement, which is one of the <a href="https://www.angi.com/articles/hvac-maintenance-checklist.htm">most important HVAC maintenance tasks</a>, costs anywhere from $5 to $20 per filter on average. Refrigerant replacement costs $125 on average. Coil cleaning costs $100 to $400. </p></div>

Q: How do I locate where the smell is coming from?

• <div><p>While a professional can always help, there are some common plumbing culprits you can check yourself to see if you can find the sewer gas smell. For example, you should check your water traps, sometimes called P-traps and S-traps, which are located under sink, shower, and laundry drains. The wax ring beneath the base of your toilet, which creates a watertight seal with the plumbing, could also have gone bad.</p></div>

Q: Can dirty air ducts affect air conditioning?

• <div><p>Yes. It's not just AC filters that get dirty. Ducts can accumulate dust and dirt quickly. Insects and animals can also get into duct systems, creating many problems. Dirt build-up and unwanted guests can constrict the airflow and cause rooms not to cool evenly. You might also see higher energy bills because they're not working as efficiently.</p></div>

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>
