What’s the Cost of Air Duct Sealing Services in Phoenix?

April 20, 2022

How much does a duct sealing cost in Phoenix?

Property sealed ducts help protect against temperature fluctuations and dust in your home. A leaky air duct can decrease the efficiency of your heating and cooling system by as much as 20% — so using an untreated system will cost you more in the long run.

Leaky ducts can also result in “backdrafting,” where gasses and pollutants like carbon monoxide leak into living spaces instead of being safely kept away.

The cost of sealing or resealing your ducts can range between $1,650 to $2,000+. Other factors that play into how expensive a duct sealant service could be include:

  1. The size of your home
  2. Accessibility of ductwork
  3. Duct sealant options
  4. Material costs

We’ll break down how these factors play a part in the overall cost of sealing your ductwork, and we’ll lay out the most common solutions your contractor should be able to provide.

Choosing air ducts for the size of your home

Depending on the size of your home, you may have more duct leaks.

The size of your home has an impact on the efficiency of your ductwork.

If the ducts are too small for the home, your cooling and heating system will struggle to move air through your home’s air vents. Rapid changes in temperature and pressure cause strain and damage to improperly sized air ducts, causing cracks to form and warps to undo bonds between seams.

These cracks leak air. Ductwork that contains large cracks need duct sealant due to the extra surface area. Extensive work will increase the cost of labor and materials.

In the case of poorly designed or installed ductwork, the system may need a total replacement. Entire system replacement can better fit the needs of your home and wallet in the long term.

Before each ductwork job, we conduct the blower door test, a diagnostic test that involves using air pressure to find the location of the leak and determine how severe it is.

How accessible is my ductwork?

Ducts can be hidden behind walls, above ceilings, or under floors. When problematic ducts require removing and replacing structural materials, the additional time and specialized labor will increase the cost of your duct sealing job.

Choosing the right duct sealant

Fortunately, you have options for duct sealant in Gilbert and other parts of Greater Phoenix. Depending on the location of the ductwork in your home and the kind of leak, some types of sealant may be more beneficial than others.

Foil tape is a foil-backed and heat-resistant sealant that’s used on small leaks to keep heat trapped inside your ductwork. This minimizes leakage and allows air to circulate appropriately inside your home. Foil tape seals small holes or cracks or wraps around connected pieces of pipe for extra support. As an external sealant, this is a potential solution for visible and easily accessible piping.

Mastic is another useful external sealant, consisting of rubber cement, to fill slightly larger cracks in ductwork. This sealant, along with mesh tape, provides a sturdy and long-term seal. Mastic is also used on easily accessible external openings.

Aeroseal is pumped inside ducts to seal cracks and openings from within. The advantage to aeroseal is that it’s capable of sealing cracks invisible to the human eye. It’s the most costly of these three options, but it’s generally expected to last up to 40 years after application and provides internal support to your ductwork.

Depending on what your contractor needs to do and the scope of the job, your situation may require more materials for completion, increasing air duct sealing costs.

As mentioned above, different sealants can change the cost of your duct sealant job. Invasive repairing and replacing of drywall or flooring in the duct sealing process can drive up prices as well.

In some cases, a technician may also recommend a total replacement of your ductwork. Replacing all the ductwork involves the most upfront costs, as it will require swapping out an old system with a new one, in addition to higher labor costs. However, it can be the most effective and efficient solution if necessary.
