What Is the Average Cost of Duct Sealing?

NexGen What Is the Average Cost of Duct Sealing

The cost of duct sealing should be a consideration for any homeowner. According to ENERGY STAR, 20% to 30% of air that moves through residential ductwork can escape through holes and poor connections.¹ Your HVAC system must compensate r the loss of heated or cooled air, which requires a great deal of energy. Properly sealing ducts can stop air leakage so your AC and heating units can operate more efficiently.

Duct Sealing Costs

As of 2024, duct sealing can cost from $500 to $4,000. The average is $2,250.² It requires inspecting HVAC ducts that run behind walls, above ceilings, and under floors. While these usually remain hidden, they can break down over time. You’ll notice the difference in reduced comfort and increased energy costs.

Sealing ducts eliminates these issues. It also has long-term cost benefits. Nonetheless, it is not cheap. We’ll look at how duct sealing is priced for each project. These are some of the factors that influence the total cost:

Not every home of the same size has the same amount and layout of ductwork. Generally, home size vs. duct sealing costs look as follows:

How to Save on Duct Sealing

You can save money on duct sealing if you’re eligible for rebates. Many states, municipalities, and utility companies offer energy efficiency rebates on services like this. Scheduling an inspection costs money, but can save by either showing you don’t have a leak or identifying a small one to fix to improve efficiency. A pressure test confirms your ducts are sealed, so you know you’ll save on your heating and cooling bills. You can also save on duct cleaning if the technician is already working on your system.

Not only did his team deliver promptly and on time, they were friendly and left with a professional install of my new A/C unit. I can’t mention the AWESOME price I got, but needless to say they can beat any deal, and will give you the fastest 1st-rate service available.

Yesterday I had NexGen install a new furnace and a/c system to replace my 30-year-old system. Their representative Jeff met with me the day before to go over the system that would work best for my home, and presented me with a price I couldn’t turn down. Incidentally, NexGen’s price was over $3,000 cheaper than all other competitors.

My call was promptly returned by Jeff and an appointment was scheduled for the next day. Jeff presented an offer that I couldn’t refuse! A crew was available that day and came, saw and conquered. I had A/C that evening at a very fair price. Highly recommend NexGen.
