One of the most common questions Kansas City homeowners ask before booking a duct sealing appointment is simple: how much does it actually cost? Most companies in the HVAC space avoid giving real numbers online, pushing everyone to “call for a quote.” This post does the opposite. We break down Aeroseal duct sealing cost in Kansas City by home size, duct complexity, and add-ons, show you what EVERGY rebates reduce your net cost to, and compare what you pay now versus what leaky ducts cost you over the next five years if you do nothing.
What Drives Aeroseal Pricing in Kansas City
Aeroseal cost is not a flat rate. Several factors shift the price up or down, and understanding them helps you set realistic expectations before getting a quote.
Home size. Larger duct systems take longer to pressurize, treat, and test. A 1,200 square foot home with a simple single-zone system costs less to treat than a 3,000 square foot home with two zones and separate supply and return runs for each floor.
Number of vents and duct runs. Homes with more registers, longer duct runs, or complex branching configurations require more time and more sealant. Finished basements with extensive ductwork, or two-story homes with duct runs passing through multiple unconditioned spaces, generally fall at the higher end of the range.
Baseline leakage level. Higher starting leakage means more sealant is consumed to close the gaps. A home with severe duct leakage may require a second injection pass to hit target specifications. This is not common but does affect price when it occurs.
Pre- and post-testing. Aeroseal projects include pre- and post-duct leakage testing as part of the certified process. These tests document the before and after and generate the data required for EVERGY rebate applications. They are standard inclusions in Green Seal Energy’s pricing, not add-ons.
Aeroseal Cost by Home Size: Real Kansas City Pricing
Here are realistic price ranges for standard residential Aeroseal duct sealing in the Kansas City area, based on home size. These figures reflect Green Seal Energy’s typical project data for the Overland Park, Olathe, Lee’s Summit, and Shawnee markets.
- Under 1,500 sq ft: $1,400 to $1,700. Typical for smaller ranches, older bungalows, and condos with limited duct runs.
- 1,500 to 2,000 sq ft: $1,600 to $2,000. The most common home size range in the KC metro. Single-story or modest two-story layouts.
- 2,000 to 2,500 sq ft: $1,900 to $2,300. Two-story homes, homes with finished basements, or properties with more complex duct layouts.
- 2,500 to 3,500 sq ft: $2,200 to $2,800. Larger suburban homes, often with multi-zone systems. Common in Overland Park’s newer subdivisions.
- Above 3,500 sq ft: $2,700 and up. Custom quotes based on system complexity and zone count.
These are all-in prices for a complete Aeroseal project including pre-test, treatment, post-test, and certified results documentation. There are no hidden charges for the test reports or for EVERGY rebate paperwork preparation.
The EVERGY Rebate Offset: Your Real Out-of-Pocket Cost
For the majority of Kansas City homeowners served by EVERGY, a meaningful rebate is available that reduces the net cost of the project. Here is what the math looks like for a typical 2,000 square foot Overland Park home.
Gross project cost: $1,850. Typical EVERGY rebate for a home at this size with average starting leakage: $450 to $600. Net out-of-pocket cost after rebate: $1,250 to $1,400.
Homes with higher baseline leakage generate larger rebates because the rebate is calculated on the volume of leakage eliminated. A 1990s home in Olathe with original ductwork and no prior sealing work might start at 400 CFM25 total leakage and drop to 70 CFM25 after Aeroseal, generating a rebate in the $550 to $700 range on a project that costs $1,800 to $2,000 gross.
Merriam, KS homeowners served by the city’s own municipal utility can stack a separate credit of up to $3,000 on top of any applicable incentives, making the net cost extremely low or even zero in some cases.

What Leaky Ducts Cost You Over 5 Years If You Do Nothing
The cost of inaction is real and worth calculating. The U.S. Department of Energy estimates that the average home loses 20 to 30 percent of its conditioned air through duct leaks. In Kansas City, where the climate runs from cold winters to hot, humid summers, HVAC systems work hard year-round.
Take a home with a $200 monthly average HVAC energy bill, which is typical for a 2,000 square foot home in the Overland Park or Lenexa area across the full year. If 25 percent of that conditioned air is escaping through leaky ducts, you are losing roughly $600 per year in energy you paid for but never experienced as comfort. Over five years: $3,000. Over ten years: $6,000.
The Aeroseal project at $1,850 gross, or $1,300 net after EVERGY rebate, pays for itself in two to three years on energy savings alone. After that, the savings are pure return. The sealed system also extends the life of your HVAC equipment because it no longer has to run as long or as hard to maintain temperature.
Beyond energy cost, leaky ducts pull unconditioned air from attics and crawlspaces into your living space, bringing dust, allergens, and humidity with it. The indoor air quality improvement from sealing those leaks has real value that does not show up on your energy bill but does show up in how the home feels.

Common Add-Ons and What They Cost
Some Kansas City homeowners choose to combine Aeroseal duct sealing with other services in the same appointment. Here is what the most common add-ons run:
Dryer vent cleaning: $100 to $175. Adding this to a duct sealing visit is efficient because the technician is already in your home with equipment. Many homeowners prefer to handle annual dryer vent maintenance at the same time as a larger HVAC project.
AeroBarrier whole-home envelope sealing: $1,500 to $3,000 as a standalone, or $1,200 to $2,500 when combined with an Aeroseal project since setup is shared. This addresses building envelope leakage in addition to duct leakage for the most complete efficiency upgrade.
Duct insulation: Varies by linear footage and location. Uninsulated duct runs in attics and crawlspaces lose additional energy through heat transfer even after the leaks are sealed. Duct insulation is often recommended alongside sealing for homes with significant exposed ductwork in unconditioned spaces.
According to Aeroseal, their duct sealing technology consistently reduces duct leakage by 90 percent or more in residential applications, making it the most effective solution available for verified, measurable duct leakage reduction.

A standard residential Aeroseal job takes three to five hours from start to finish. That includes the pre-treatment duct leakage test, preparation of the system, the injection process, and the post-treatment test. Larger homes or systems with high starting leakage may run toward the five-hour end. Most homeowners can stay in the home during the process or return mid-day to find it complete.

Pricing is consistent across the Kansas City metro including Overland Park, Olathe, Shawnee, Lenexa, Lee’s Summit, Blue Springs, Liberty, Independence, and Prairie Village.
