air duct cleaning and sealing

Ever wondered what lurks inside those vents in your walls and ceilings? You’re not alone! Air ducts are the hidden heroes of your home, quietly delivering warm or cool air throughout your space. But like any hard-working hero, they can get a bit dusty and leaky over time. This is where air duct cleaning and sealing come in.

Cleaning your air ducts means getting rid of the dust and debris that piles up in the pipes, moving air around your house. This makes the air inside your home better to breathe. On the flip side, air duct sealing takes care of any leaks or cracks in these pipes, making sure energy is used wisely and stopping more dust from settling in. 

When you do both cleaning and sealing, your home becomes a healthier and cozier place with an efficient heating and cooling system.

So, let’s dive into the real deal of what keeps our homes breathing smoothly and our wallets happy.

What is Air Duct Cleaning?

Imagine your ducts as air highways for your home. Just like any highway, they can accumulate dust, dirt, and even allergens like pollen over time. Air duct cleaning is like giving these highways a thorough sweep, removing all the built-up debris that could be affecting your indoor air quality.

So, cleaning your air ducts is like giving your AC system a good wash from all the things like dust, bugs, and mold that can get stuck in there. If you see mold, pests, or dust coming out of your vents, it’s a sign you need to get them cleaned. 

The professionals use a vacuum method where they close off your vents, attach a blower with a brush to one end, and use a vacuum on the other end to suck up all the loosened dirt.

To stop your ducts from getting dirty, make sure to change your air filter regularly and keep your home clean to reduce dust. The air filter in your AC catches dust and debris, but when it’s full, it can’t do its job properly, letting dirt into your ducts.

What is Air Duct Sealing?

Think of leaky ducts as cracks in the road, allowing conditioned air to escape and wasting your energy. Sealing air ducts is like patching up those cracks, ensuring that the air reaches its destination efficiently. This can save you money on your energy bills and improve the overall comfort of your home.

So, duct sealing means repairing the holes and gaps in your ductwork. There are a few common ways on how to seal air ducts:

  • Some HVAC experts use foil tape to cover holes on the outside of ducts. This works well for big leaks or visible cracks, but might not catch very small leaks.
  • Masking is another way for larger holes. Small holes get blocked with rubber cement, and larger ones are covered with mesh tape and sealed.
  • The Aeroseal method is a bit pricier but more effective and long-lasting, up to 40 years. A professional pumps a sealant through your ducts, closing up all the holes. This is great for finding and fixing smaller, hard-to-spot leaks.

Energy Star says that about 20–30% of your AC’s cool air can escape through leaks. That’s like throwing money away on your energy bills! If your ducts are leaking, sealing them up is worth the cost.

Do I Need Both Air Duct Cleaning and Sealing?

While cleaning can remove existing debris, sealing addresses the root cause of future dust build-up. Sealing leaky ducts helps prevent dust from entering the system in the first place, which ultimately maximizes the benefits of cleaning and keeping your air cleaner for longer.

Here are some signs that you might need both servicing:

  • High dust levels: Noticing an increase in dust throughout your home, even with regular cleaning? Leaky ducts could be pulling in dust from your attic or crawl space.
  • Uneven temperatures: Do some rooms feel consistently hotter or colder than others? Leaky ducts might be directing conditioned air away from certain areas.
  • Increased allergies: Suffering from allergy or asthma symptoms? Dust and allergens trapped in your ducts can exacerbate these issues.
  • High energy bills: Leaky ducts can force your HVAC system to work harder, leading to increased energy consumption and higher bills.

How Much Does It Cost?

The cost of duct cleaning and sealing can vary depending on the size of your home, the complexity of your duct system, and your location. It’s always best to get quotes from several reputable companies before making a decision.


  • Do your research: Find a qualified and certified company with experience in both cleaning and sealing. Ask for references and check online reviews.
  • Get multiple quotes: Don’t settle for the first offer you receive. Compare prices and services from different companies.
  • Be wary of aggressive sales tactics: A reputable company will focus on educating you and providing a fair estimate, not pressuring you into a quick decision.
