Why insulate ductwork?

• <div><p>When you insulate ductwork, you help protect the air moving through the system from external conditions and keep it sealed within the ducts. This makes your HVAC system more efficient since it doesn’t have to work as hard to heat or cool your home. Insulation can help lower your energy bills and prevent problems like condensation and mold formation inside your ducts. </p></div>

Q: How do you keep your air vents working properly?

• <div><p>You can keep your air vents working properly by regularly cleaning them and replacing any air filters as necessary. Your air vents will also work best if you clean and lubricate the exhaust fans and reduce humidity to prevent condensation on them. </p></div>

Q: Why do my vents keep getting moldy?

• <div><p>Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.</p></div>

Q: How do you know if your ducts are clogged?

• <div><p>There are several signs that your ducts might be clogged, such as encountering more dust in your home, dirty air vent covers, airflow and temperature changes from room to room, noticeable mold growth, and higher energy bills. If you notice these signs, shine a flashlight down your ducts and inspect for clogs or blockages.</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>
