You may have thought about having the air ducts sealed in your Phoenix home or business, knowing it will save you money in the long run. Yet you worry: How much does duct sealing cost? How long will it take to recover your investment? Who does the best, most professional job?
Common Duct Sealing Questions
Have general questions about the duct sealing process? If so, continue reading to see commonly asked questions and we’ve included a FAQs question towards the bottom of the page.
What is Duct Sealing?
Two popular methods of duct sealing are in use today:
1. Exterior sealing, usually by hand;
2. Interior duct sealing, using high technology.
Howard Air uses advanced Aeroseal duct sealing. An efficient aerosol spray is injected under pressure into the ducts, sealing every crack and crevice from the inside. This method is vastly superior to hand-brushing a sealant on the outside.
Pressure inside the ducts automatically forces the fast-drying aerosol into cracks, where it closes up the holes and dries to become a solid. Brushed-on exterior sealing may or may not close up all air leaks.
How Much Does Air Duct Sealing Cost?
So… how much does duct sealing cost?
Duct sealing costs between $1,500 and $2,500 on average per air conditioner. But keep in mind that there are a lot of different factors that will attribute to the final cost, including size of home, location and age of duct system, plus method of sealing you choose.
Any measure of the investment for duct sealing has to include an estimate for the savings the process brings. For this you need to consider your options:
- Live with leaking ducts that lose expensively treated air at a high rate. Typical residential loss is several hundred cubic feet per minute (CFM), but for large commercial properties, this can be over 40,000 CFM.
- Replace an entire duct system.
- Have ducts sealed externally.
- Have ducts sealed the modern, efficient way, such as Aeroseal.
The least expensive option is the last one: having your HVAC contractor use Aeroseal to close up holes and leaks from inside your ducts.
How Much Does Aeroseal Duct Sealing Cost?
Each Phoenix property is different, so a precise cost for a particular job can only come from having an HVAC representative come to your home or business to measure and give an estimate.
Plenty of research indicates the return on investment (ROI) for duct sealing is superior to just about any other home improvement, with figures ranging from the federal Energy Star’s 20 percent improvement in HVAC energy efficiency to McKinsey & Company’s cost recovery estimate of two to three years.
Most Phoenix HVAC systems are designed for a minimum of 10 years’ dedicated service. Having your ducts sealed using Aeroseal, and then recovering the cost of that sealing in only two or three years, means you lock in many years of improved energy efficiency, a smaller carbon footprint, cleaner indoor air, and happier family members or customers.

Want to know how ducts are sealed, eh? There are a few ways to seal ducts, including with the use of duct tape, mastic, and Aeroseal.
- How Does Aeroseal Work?
Aeroseal works to seal ducts from inside the duct by sealing escaping air with polymer particles.
- How Do I Seal Vents and Registers?
Vents and registers are best sealed when installed properly. If you still have gaps, try duct tape or foam weatherstrip tape.
- How is Duct Seal Used?
There’s a right way and a wrong way for how to use duct seal. Duct seal, like Aeroseal, is used to locate hard to find and reach gaps in your duct system and fill those gaps with polymer particles.
- How Can I Seal Air Ducts?
If you want to know how to seal HVAC air ducts like a pro, you really need specialized equipment. However, if you can reach your duct system, duct tape is a great alternative.

Sealing ducts in the basement is the same process as the rest of the home. If you can access the duct, try tape first. If not, get the pros to Aeroseal the duct system.
- How Do I Seal Ductwork from the Inside?
Ducts can be sealed from the inside of the duct with the use of Aeroseal and polymer. When the polymer is introduced to the duct it sticks to the metal framing first and then to itself to close gaps and make them airtight.
