How Much Does Duct Sealing Cost in Phoenix?

In Phoenix, the cost of duct sealing costs anywhere from $1,600 to $2,000+. We’ll go into pricing variabilities below.

We know—this service has an expensive price tag. The reason the job is expensive is because it is time-consuming, which leads to increased labor costs.

That said, it’s better to invest in duct sealing now rather than continuing to deal with leaky duct problems (such as poor indoor air quality and higher energy bills).

Wondering what causes the cost of duct sealing to go up or down?

The total cost to seal your ducts will depend on the following factors:

• The size of your home
• The condition & location of your home’s ductwork
• Sealing vs replacing ducts
• The contractor you hire

Let’s look at each of these factors in more detail below to give you a better idea of what you’ll pay to have your ducts sealed.

Larger homes have more ductwork and registers, which means duct sealing will take longer compared to a smaller home. Because of the increased labor time and additional materials, the overall expense of the project will be greater.

If your ducts are in poor condition (meaning they have significant leaks or holes), then the cost of duct sealing will increase because the job will take longer.

Additionally, the location of your ducts will affect the cost of the project. Leaky ducts located in hard-to-reach areas of your home (behind walls, for example) will require more labor to seal, which increases the overall cost. If the technician needs to cut into a wall or ceiling to access the ducts, you’ll need to factor in restoration costs as well.

It’s more expensive to replace faulty ducts than to seal them, but sometimes replacement may be the best option.

For example, if the leaks in your ducts are severe or widespread, then the technician may recommend duct replacement over sealing. Replacement is often the best option if your leaky ducts are old or if they were incorrectly installed/sized to begin with.

On the other hand, if the leaks in your ductwork are relatively minor, the technician will recommend duct sealing.

In general, high-quality HVAC contractors charge more for their duct sealing services. That said, when it comes to duct sealing, you get what you pay for.

Inexperienced contractors, or those looking to make a quick buck, will often rush through the job or cut corners. Whether intentional or not, this ultimately leads to sloppy work and in some cases, can even worsen the condition of your ducts.

To avoid these problems, we recommend hiring a high-quality, experienced contractor. That way, you can have peace of mind that you’ll get solid duct sealing work from a trained professional who knows what they’re doing.

As you look for contractors to hire for the job, ask yourself the following questions:

• Is the contractor licensed and insured?
• Has the contractor been in business for at least 10 years?
• Does the contractor have positive customer reviews? (You can check sites such as Google, Better Business Bureau and Facebook.)
• Does the contractor offer guarantees on their duct sealing services?
• Does the contractor offer upfront, transparent pricing?

If you answered “yes” to the questions above, chances are the contractor has sufficient experience and will do high-quality duct sealing. If you answered “no” to any of the questions above, we recommend that you continue your search for a contractor.
