Mason County PUD No. 3 offers a wide variety of programs for customers with electrically heated homes that can improve their energy efficiency. There are incentives available on upgrading a home's heating system, rebates on new energy efficient appliances, and many more possibilities that you can learn about below.

If a single-family electrically heated site-built home has an electric forced air furnace; or baseboards, wall heaters or other zonal resistance heating permanently installed as its primary heat source; or if a manufactured home has an electric forced air furnace; it may qualify for PUD 3’s ductless heat pump incentive.

▪ The ductless heat pump must be a split system heat pump employing an inverter-driven outdoor compressor, with an inverter-driven or variable speed indoor blower. A qualified equipment list can be found on BPA's website at www.bpa.gov/ResHVAC

▪ The ductless heat pump must be installed according to the manufacturer's specifications

▪ If a home has existing duct work, PUD 3 strongly recommends the duct work is tested and sealed according to the PTCS Duct Sealing program requirements. An incentive may be available

▪ Mobile homes assembled before 1977 do not qualify

▪ A PUD 3 altered service application is required

▪ Washington State Labor & Industries electrical, and Mason County or City of Shelton mechanical permit numbers are required upon project completion

▪ The certified contractor must fill out and submit the Ductless Heat Pump Installation Form to the PUD 3 conservation department documenting the condition of the home's existing heating system and the intended operating strategy

If a site-built or manufactured home has an electric forced air furnace, it may qualify for PUD 3’s air source heat pump CONVERSION program.

▪ The new heat pump must have a Heating Seasonal Performance Factor (HSPF) rating of 9.0 or higher and a Seasonal Energy Efficiency Ratio (SEER) rating of 14 or higher and must be AHRI tested and certified

▪ Mobile homes assembled before 1977 do not qualify

▪ A PUD 3 altered service application is required

▪ Washington State Labor & Industries electrical, and Mason County or City of Shelton mechanical permit numbers are required upon project completion

▪ PTCS heat pump commissioning tests are required on all units

▪ A PTCS duct sealing test is required when 50% or more of duct work is located in unconditioned space. A PUD 3 conservation technician can assist in determining the location of duct work. The results of the test will determine the incentive amount below

Performance Tested Comfort System (PTCS) duct sealing is available for electrically heated site-built and manufactured homes with a forced air furnace or air source heat pump where the majority of ductwork is located in unconditioned space. Leaky ducts will greatly reduce a home’s energy efficiency. A PTCS certified technician can seal a home’s ducts, and PUD 3 may be able to help cover the cost. A PTCS certified technician can be found at www.ptcsnw.com. PTCS forms can be found at bpa.gov/reshvac.
