Seal in savings with a duct test and repair

Leaky ducts can cost you $200 or more a year.

Does your home have a room that is too hot in the summer or too cold in the winter? The culprit may be leaky ducts. In a typical home, about 20% of the air that moves through the duct system is lost because of improper installation.

SRP's Duct Test and Repair rebate helps you identify places in your home where energy escapes. Our rebate program offers up to $75 toward duct testing and up to $175 for qualified repairs. To qualify for the rebate all test and repairs must be completed by BPI-certified contractor.

Testing and repair costs

For a typical home, testing can range from $100 to $450 and repairs normally cost $300 to $1,000. Houses and equipment can vary; therefore, actual costs may be higher or lower. In the example below, we've calculated an average customer's out-of-pocket costs (including the SRP rebate) for testing and repair services.

Example of customer out-of-pocket costs

Your ductwork repairs include

  • Sealing plenums, elbows, inside of supply boot at the flex or sheet metal.
  • Sealing starting collars at all branch ducts on returns and supply boxes.
  • Sealing all air leaks at the refrigerant lines connecting to the evaporator.
  • Sealing all high and low voltage connections to the indoor/outdoor equipment.
  • Sealing all drain/refrigerant line gaps through structural penetrations.
  • Removing all ceiling/sidewall registers and return air grille to caulk between sheetrock and metal boxes.
  • Replacing return air box and/or grill if it is undersized and the system has a high static pressure.*
  • Insulating all bare exposed metal supply and return air ducts and plenums.
  • Sealing open holes behind wall thermostats.
  • Sealing all return air chases from lower floor walls to attic with fiber duct board or sheetrock and mastic.
  • Sealing all equipment platforms in closets or garages.
  • Replacing equipment door panel seals as needed or seal equipment panels with UL foil tape.

  • *Contractors may recommend increasing and adding additional return air ducts before sealing ducts. Homeowners who decline a contractor's recommendation to properly size the duct system, prior to duct sealing, may reduce the air conditioning systems cooling capacity and this could cause energy costs to increase.
