Duct Sealing

What is covered by the program?

Duct sealing rebates are available for existing single-family or manufactured homes with ducts that are connected to electric heat.  The work must be performed by one of Franklin PUD’s Authorized Contractors
Eligible work includes repairing damaged and disconnected ducts; straightening flexible ducts that are tangled or crushed; sealing leaks and connections with mastic or an approved sealant, and insulating ducts in unconditioned areas.  At least 30% of the home’s supply ducts must be located in unconditioned space (i.e., crawlspace, attic with floor insulation and unheated garage) and be accessible. 
Unless otherwise indicated, all Franklin PUD energy efficiency upgrades must be installed by authorized contractors who have received special training and certifications required to meet utility specifications and have signed agreements to help insure a standard of efficiency and durability have been met.

Rebates effective through September 30, 2018 or until funding expires:

Who qualifies for this program?

Current Franklin PUD customers who own single-family or manufactured homes whose primary heat source is electric. Renters may qualify with the owner’s consent.

Why should I consider duct sealing?

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. In a typical house, however, about 20 to 30 percent of the air that moves through the duct system can be lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.

How do you know that your home may have poorly performing ducts?

  • you have high summer and winter utility bills;
  • you have rooms that are difficult to heat and cool;
  • you have stuffy rooms that never seem to feel comfortable;
  • you find tangled or kinked flexible ducts in your system;
  • you feel drafts at your registers when the system is not running.

What types of duct sealing are available?

Performance Tested Comfort Systems (PTCS) and Prescriptive Duct Sealing are Pacific Northwest regional programs promoting contractor training for quality duct sealing (as well as heat pump installation).  The duct sealing requirements and specifications focus on energy saving duct sealing that will result in increased comfort and energy savings.  PTCS and Prescriptive Certified Technicians complete a BPA-approved training and sign a participation agreement in order to be certified to work in this program.

What’s the Difference?

PTCS Duct Sealing requires that a pre-leakage test be conducted prior to sealing and a post-leakage test conducted after sealing. Prescriptive Duct Sealing does not require any pre- or post-leakage testing.

PTCS Prescriptive Duct Sealing does not require pre- and post-testing and is often quicker and less expensive than pressure tested duct sealing.  The prescriptive path often begins with a visual inspection of your duct system and focuses duct sealing in high pressure areas and other areas known to be problem areas based on industry experience with duct systems in this region.
