Professional Duct Sealing vs. DIY: Which Option is Right for You?

Energy bills increase during summer and winter due to HVAC systems working overtime and energy efficiency is lower. However, if your bill seems high and the temperature remains uncomfortable, it may indicate issues with air ducts. Today, our specialists explain when air duct sealing can be a DIY project and when you should call a professional.

How to identify the poor performance of my duct?

Before you take on a duct sealing DIY project or call a professional, you'll need to make sure the work actually needs to be done. Here are some common indicators that your air ducts might need sealing:

  • If you have high summer and winter utility bills
  • If you have rooms that are difficult to heat and cool
  • If you have stuffy rooms that never seem to feel comfortable
  • If your ducts located in an attic, crawlspace, or the garage
  • If you find tangled or kinked flexible ducts in your system when checking it.

Answering yes to even one of these questions is a good indicator that your ducts need sealing. Answering yes to all means you need to get to work ASAP in order to reduce energy costs.

DIY duct sealing: Is it feasible for you?

Duct sealing is a popular DIY project for HVAC improvements. There are pros and cons to this, but it depends mostly on your ability and willingness to complete it alone. Before starting, research the best methods and common errors when doing DIY for HVAC improvements.

To test for air leaks in duct connections, use a lit incense stick or toilet paper. Hold it next to the ducts while the air is on. If smoke or paper moves erratically, an air leak is present.

To seal air ducts, use mastic sealant. Duct tape is a poor choice because it is prone to peeling. If you do prefer tape, consider HVAC aluminum foil tape.

Professional duct sealing: When to seek expert Help?

HVAC duct sealing can be a complex task that requires knowledge of HVAC systems and proper sealing techniques. We recommend consulting with professionals if you feel you have even the slightest chance of damaging your ductwork further. Here are a few reasons why you should call a professional:

Repairs Are Quicker

The time required to locate ducts and air leaks can make DIY duct sealing a time-consuming project to take on. Professionals, with specialized computers and extensive experience, can easily locate and seal air ducts, saving time and ensuring proper installation.

Professionals also have access to advanced equipment like thermal imaging cameras, which can quickly identify hidden leaks that may be difficult to detect with the naked eye. Their expertise allows them to use the most effective sealing techniques and materials, such as Aeroseal, resulting in long-lasting and efficient ductwork. 

Ducts Can Sometimes Be Hard to Reach

Air ducts are found in various parts of your home and living space, including walls, ceilings, attics, and basements. Reaching these leaky ducts can be challenging, especially inside walls or basements. So, you may not want to take a DIY approach to duct sealing if you do not have the specific tools needed for the job or are having problems obtaining sealant for all necessary areas. This approach may also not be for you if you anticipate encountering problems you may not be able to solve.  

When you go to professionals for duct sealing services, you'll know experienced experts will have the necessary tools and expertise to access and seal ducts effectively to provide an energy-efficient living environment. They'll identify any underlying issues, such as leaks or damage, that may require additional repairs.

Professionals Can Use Special Computer-Based Systems

As we mentioned above, ducts can sometimes be difficult to find. This means you may need to rip out your walls and rip open your ceiling to find them. And even if you do, it can be challenging to find a leak if you're unsure of exactly what you're looking for.

Professional air duct sealing companies have special computer systems that can help find the leaky ductwork in your home. And they can do it without having to tear your walls down. A nice trade-off, we'd say, considering you won't then have to pay for wall repairs and you will have improved indoor air quality.
