You are viewing the Maysville, KY location.
When homeowners hear about duct sealing in Aberdeen, KY, their first instinct is often to grab a roll of duct tape. After all, the name itself suggests it’s the perfect solution, right? Unfortunately, that’s far from the truth. At Premier Heating & Air, we frequently see the aftermath of DIY duct sealing attempts using duct tape, and we can tell you with certainty that it doesn’t work. In this post, we’ll explain why duct tape is ineffective for sealing ductwork, why DIY fixes usually fail, and how professionals properly seal ducts for maximum efficiency.
How should professionals properly repair leaking ducts?
- Begin with a comprehensive inspection, locating leaks at joints, seams, and hidden areas using diagnostic tools.
- Use mastic sealant or UL‑rated foil-backed HVAC tape, not duct tape, for durable, code-compliant sealing.
- After sealing, test the airflow and pressure to verify the efficiency and integrity of the repair.
- Schedule routine checks to ensure seals remain effective and protect indoor air quality.
Why Duct Tape Fails for Duct Sealing
Despite its misleading name, duct tape is one of the worst materials to use for sealing air ducts. Here’s why:
- Heat Causes Adhesive Breakdown – Your HVAC system pushes heated and cooled air through your ductwork, and over time, temperature changes cause the adhesive on duct tape to deteriorate. Once the adhesive dries out, the tape peels away, leaving gaps and leaks.
- Lack of Long-Term Durability – Even if duct tape appears to hold up initially, it quickly degrades under the constant exposure to air pressure and temperature fluctuations. In a few months, that “fix” you applied will have failed.
- Code and Safety Issues – Building codes do not approve traditional duct tape for sealing ducts. Instead, professionals use specialized materials that are tested for HVAC applications.
The Risks of DIY Duct Sealing
Some homeowners attempt to fix duct leaks on their own, thinking it will save them money. Unfortunately, these DIY fixes often do more harm than good. Here’s why:
- Hidden Leaks Remain Unfixed – Most homeowners can only access a small portion of their ductwork. The majority of leaks occur in areas that are difficult to reach, such as attics, crawl spaces, and behind walls.
- Inefficient Seals Waste Energy – Without the right materials and techniques, DIY sealing won’t be airtight, leading to continued energy waste.
- Compromised Indoor Air Quality – Poorly sealed ducts can pull in dust, allergens, and contaminants from unconditioned spaces, lowering the air quality in your home. This can lead to discomfort and even health issues. Here’s how to determine if you have poor indoor air quality before the problem worsens.
- Increased Strain on Your HVAC System – Air leaks make your HVAC system work harder to maintain comfortable temperatures, leading to higher utility bills and unnecessary wear and tear. Addressing duct leaks is one of the services that help improve indoor air quality while also boosting system efficiency.
