Are you tired of dealing with an inefficient HVAC system? Do you wish you could make your home more energy-efficient and comfortable? Has an HVAC technician told you that your air ducts are cracked and leaking? If so, then Duct Armor may be the perfect solution for you. Keep reading to learn all about Duct Armor air duct sealing and how it can benefit your home.
What Is Duct Armor?
Duct Armor is an advanced air duct restoration and duct sealing process that applies a thick, rubberized latex lining to the inside of your existing HVAC system ductwork. This specialized coating:
- Seals leaky ducts and stops conditioned air from escaping through cracks, holes, and poorly connected ducts.
- Prevents air leaks that waste energy and cause inconsistent temperatures in your home.
- Blocks dust, allergens, pests, and moisture from entering your air ducts, improving your home’s air quality.
Because the coating forms a seamless, airtight barrier, it also reduces noise from your HVAC system, making your home quieter and more comfortable. The durable latex material doesn’t easily peel or break down, and the installation process typically takes only a few hours.
Whether you have hidden leaks or visible damage in your duct system, Duct Armor restores your ductwork from the inside out—protecting it from further deterioration, improving energy efficiency, and ensuring your heating and cooling equipment can operate at its best.
Duct Armor Vs. Other Duct Sealing Methods
There’s more than one way to seal leaky ductwork—but not all methods provide the same results, especially for hidden leaks or inaccessible areas. Here’s how Duct Armor compares to common options:
- Duct Tape: Despite the name, standard duct tape isn’t a reliable long-term fix for duct leaks. It can dry out, peel away, or lose adhesion over time—especially when exposed to temperature changes inside your HVAC system. It’s best reserved for temporary, visible repairs, not for restoring your duct system.
- Foil Tape: More durable than duct tape and often used by HVAC technicians for sealing ducts at accessible joints. However, foil tape only works on areas you can reach and doesn’t address hidden leaks deep inside your ductwork.
- Mastic Sealant / Duct Mastic: A thick, sticky sealant that’s effective for sealing ducts around seams, connections, and holes. While it can create a strong bond, mastic sealing can be messy to apply, and like foil tape, it can’t easily reach inaccessible areas or coat the inside of the ducts completely.
- Aerosol Sealing: This process uses sealant particles blown through the duct system to plug leaks from the inside. While it can help with smaller leaks, it’s not designed to fully restore leaky ductwork that’s rusted, deteriorated, or contaminated, and it doesn’t add a protective lining.
Bottom line: While traditional duct sealing methods can help in certain situations, Duct Armor delivers a complete duct restoration—protecting your ducts, improving your home’s air quality, and providing energy savings for years to come.
More Benefits of Duct Armor Air Duct Sealing
Sealing your ducts with Duct Armor does more than just fix duct leaks—it improves your comfort, protects your home, and helps your HVAC system run at peak performance. Here’s how:
1. Lower Energy Bills and Better Efficiency
Leaky air ducts force your heating and cooling equipment to work harder, wasting energy and driving up your energy bills. By creating sealed ducts from end to end, Duct Armor stops air leaks and keeps conditioned air where it belongs—inside your living spaces.
2. Improved Indoor Air Quality
When ducts have cracks, holes, or poorly connected connections, they can pull in dust, dirt, allergens, and even pests from crawl spaces, attics, or wall cavities. These contaminants then circulate through your home. Duct Armor’s continuous lining blocks these entry points, improving your home’s air quality and reducing the spread of irritants.
3. Consistent Comfort in Every Room
Hidden leaks and inaccessible areas in your duct system can cause inconsistent temperatures, with some rooms always too hot or too cold. Sealing ducts with Duct Armor allows your HVAC system to distribute air evenly, keeping every space comfortable year-round.
4. Protection from Moisture and Rust
In-slab or underground ducts are vulnerable to moisture intrusion, which can lead to rust, corrosion, and eventually major damage. Duct Armor’s lining acts as a moisture barrier, protecting your ducts from these costly problems.
5. Extended Duct System Lifespan
The average home’s air ducts last around 20-25 years, and replacing your duct system can be difficult and expensive. By having Duct Armor installed instead, you can expect your ducts to last you even longer.
Leaky air ducts often come from a few common causes—including poor installation, loose connections, rust, and damage from pests or moisture. Watch for the common signs that you need to act now, such as uneven heating or cooling, rising energy bills, dust buildup, or unusual odors from your vents. Addressing these issues quickly with Duct Armor air duct sealing can stop the leaks, protect your duct system, and keep your home comfortable and energy efficient.
How Long Does Duct Armor Last?
Duct Armor is built to last for decades! The lining comes with a 15-year warranty, which means you’re covered if any issues arise during that time. With proper HVAC maintenance, many homeowners find that it continues protecting their ducts well beyond the warranty period—often for the life of the home.
Is Duct Armor Right for Your Home?
If you’re a homeowner with in-slab ductwork or underground ducts, you may already be dealing with moisture, rust, or other damage. Duct Armor was designed with these situations in mind. Its specialized spray-applied lining seals leaky ducts, protects against corrosion and water damage, and restores your duct system so it moves air efficiently again.
It’s also ideal if you have an older duct system that’s developed significant leaks, or if you’re simply looking for ways to make your home more energy-efficient and comfortable without the cost of full duct replacement. Homes with a large number of vents especially benefit, since they’re more prone to air loss from wear and tear.
Here’s a quick checklist to see if Duct Armor might be right for you:
- Your ducts are buried in concrete, routed underground, or in hard-to-access crawl spaces behind walls or above insulation.
- Some rooms in your home are always too hot or have cold spots that never seem to go away.
- You have increased energy bills even though your HVAC usage hasn’t changed much.
- An HVAC technician has told you there’s duct leakage, rust, or poorly connected ducts.
- You notice dust buildup around vents or on furniture shortly after cleaning.
- You’ve heard unusual noises coming from your ductwork during system operation.
- You’ve had issues with moisture, pests, or musty odors coming from your ductwork.
If several of these apply, Duct Armor can give you sealed ducts, improved indoor air quality, and long-term energy savings—all without tearing out and replacing your entire duct system.
