Inquire Today: FREE Assessment


The price of your job will depend on accessibility to your furnace and plenums, the number and location of registers in the subsystem, and whether we’re sealing one or both subsystems. If we have to make exceptional repairs to your duct subsystem(s) before sealing, that will also affect the price.

For example, if your supply subsystem is comprised of 16 registers – half on the floor and half on the wall, the sealing price will typically be $1550 to $1850. If you additionally have your eight-register panned/wall-cavity return subsystem sealed, expect the total price to be $2850 to $3250. (If your return subsystem is fully ducted – most constructed before 2012 are not, sealing is much quicker and the total price could be $500 to $600 less.)

In addition to the substantial energy savings most homeowners enjoy after we Aeroseal their ducts, you may be eligible for financial incentives through the Home Performance with ENERGY STAR Program administered by NYSERDA. We will be happy to assist you in applying, including scheduling a comprehensive energy assessment (free for most New Yorkers) by one of our industry partners prior to our sealing application.

For qualified applicants, current incentives from NYSERDA include:

  • 10% rebate after the work is complete.
  • For income-eligible households, a grant to pay up to 50% of the cost. (Two- to four-unit building owners may also qualify).
  • Affordable low-interest loans or on-bill financing with Energy Finance Solutions .
