How Much Does Air Duct Replacement Cost in Phoenix? [2025 Data]

When summer temperatures soar, the last thing you want is for the cold air from your AC to leak out of your worn-out air ducts. Ready to update your ductwork? Expect to spend $893 on air duct replacement in Phoenix, with most projects ranging from $447 to $1,587, depending on the size of your home, the type of duct material, and how easy or challenging it is to access your ducts.

Air Duct Replacement Cost Factors 

The cost of replacing air ducts in your Phoenix, AZ, home depends on several factors. For Phoenix residents, choosing a well-insulated duct material may cost more but is essential for saving money on utility bills in such a hot climate. Home size and duct location are also important influences on the cost.

Size

The size of your home directly affects air duct replacement costs. Larger homes require more materials and labor to replace the entire duct system. On average, the cost ranges from $2,000 to $5,000 for a small- to medium-sized home. However, duct replacement can run as low as $1,400 for smaller homes and as high as $9,000 for larger homes. Here’s how the size of your home affects duct replacement costs:

Duct Location

If only specific sections of your ductwork need replacement, such as in a renovation project, costs will depend on the location of the damaged or worn ductwork. Replacing ducts in hard-to-reach or concealed areas—like attics, basements, ceilings, walls, or crawl spaces—can increase labor costs. Here’s how the location of the ducts could affect their cost:

Duct Material

The material you choose for your replacement ducts affects both their cost and longevity. The most commonly used duct material in Phoenix, AZ, is sheet metal, which is ideal for withstanding the hot, dry climate.

Sheet metal ducts are durable but pricey. Flexible ducts, on the other hand, are more affordable but may need to be repaired or replaced sooner. Here’s a breakdown of air duct replacement costs based on duct material:

HVAC Pro Costs

Labor costs for duct replacement are around 60% of the project total. For hourly rates, expect to spend $50 to $110 per hour, with the average air duct replacement job taking five to seven hours.

When it’s time to replace your air ducts, hire an HVAC pro in Phoenix, AZ, to do the job. HVAC pros have the right skills and tools to do the job safely, correctly, and quickly, so you can worry less about replacing the ducts and enjoy the cool air coming from your efficient HVAC system.

Permits

Your HVAC pro will include the cost of permit fees in their quote, but fortunately, they’ll handle all the paperwork for you. Phoenix building permits are based on the cost of the project. Projects up to $1,000 have a base fee of $150, then you’ll pay $9 for each additional (or fraction of) $1,000 up to $10,000.

Additional Pros to Consider Hiring

Although an HVAC pro is the best person to hire for air duct replacement, you may need to take on other projects at the same time. For instance, if you have old air ducts in your walls or ceiling, you may need to pay for mold or asbestos testing before the replacement, and you’ll need a drywall repair afterward.

Here’s what you can expect to spend on the following projects in Phoenix:

• Drywall repair cost: $270–$730

• Mold remediation cost: $930–$2,750

• Asbestos testing cost: $210–$530

• Insulation installation cost: $750–$1,600

Does Air Duct Replacement Increase Home Value?

Air duct replacement can make your home more marketable to potential buyers, and if you invest in a new HVAC system alongside the upgraded ductwork, you could increase your home value by 5% to 7%. Plus, with efficient, tightly sealed new ducts, you can enjoy more comfortable indoor temperatures and lower heating and cooling bills.
