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>

What causes condensation on air vents?

• <div><p>Condensation forms when warmer, outside air combines with cooler air in your ductwork. This can happen when there are leaks in your air ducts, your HVAC system has a dirty air filter, or there’s a lack of insulation around the ducts. To prevent it from happening, replace your HVAC filters as directed. Also, once every five years, hire a <a href="https://www.angi.com/nearme/air-duct-cleaning/">local air duct cleaner</a> to clean and inspect them.</p></div>

Do all houses have ducts?

• <div><p>No, not all houses have ducts. It would be safe to say, however, that most modern houses do. The reason is that older houses had boilers in the basement that heated from the bottom up and often vents weren’t built into the house. Another reason is that older homes don’t have air conditioning (because it didn’t exist) and use radiators for heating. Since radiators don’t require ductwork, it wasn’t built.</p></div>

Q: How can you tell if an AC vent is open or closed?

• <div><p>There are a few ways to determine if a vent is open or closed. You can inspect the vent and examine the position of the fins. If there are spaces between them, the vent is open. If the fins are flat and touching, the vent is closed. You can also stand under the vent when the system is running to see if you feel air flowing through it.</p></div>

Q: What is the black stuff around my air vents?

• <div><p>Seeing black dots around the air vents is alarming, but don&rsquo;t worry. It&rsquo;s probably just a build-up of soot and darkened dust. Soot is just a byproduct of burning organic materials, so it tends to form in the winter months. </p></div>
