What Tacoma Power pays in 2026
We read Tacoma Public Utilities' heat pump, insulation, window, thermostat, water heater and EV charging pages on October 6, 2026. Most rebates need a Tacoma Power Participating Contractor and do not cover do-it-yourself work. Several only apply when your main heat is electric, so check what heats your home before you plan.
Heat pump
$1,000 for a ductless or standard air-source heat pump replacing electric heat, $2,000 for a variable-speed heat pump replacing an electric forced-air furnace, and $1,000 for a variable-speed heat pump replacing non-electric heat or an old heat pump.
Insulation
$750 for each area of crawlspace, wall and attic. Your insulation must start thin and reach a set level, and your main heat must be electric.
Windows and sliding doors
$100 per window and $400 per sliding door replacing single-pane glass. $50 and $200 replacing double-pane metal frames.
Heat pump water heater
For replacing a standard electric water heater with a Tier 3 or Tier 4 model. You can hire a contractor or install it yourself.
Smart thermostat
Up to two rebates, one for each heating system. Line-voltage thermostats earn $25.
Home EV charging
Bill credits of $400 each for a Level 2 charger, a smart splitter, electrical work or a 240-volt outlet, with a $600 maximum for more than one. Renters can apply.
A quick example
Picture a Tacoma home with an electric forced-air furnace, a bare attic and a floor with no insulation. A variable-speed heat pump pays $2,000, attic insulation $750 and floor insulation $750, which is $3,500 from Tacoma Power. Tacoma Power's zero percent loan can then cover part of the rest, up to $20,000 for the heat pump and up to $10,000 for insulation, paid back over seven years.
The zero percent loans
Tacoma Power offers seven-year loans at zero percent interest. For a heat pump the loan can be up to $20,000 when your home now heats with electric zonal heat or an electric forced-air furnace. For insulation it can be up to $10,000 when your main heat is electric and your insulation starts thin. You must own the home and the land, you need a good payment and credit history with Tacoma Public Utilities, and Tacoma Power must approve the project before work begins. Heat pump loans are not offered if you already have a heat pump.
A loan with no interest is worth about as much as the interest you would have paid elsewhere, so it can be worth more than a small rebate. Ask for the pre-approval form first, before a contractor schedules work.
Rules that matter on the heat pump rebate
The home must be served by Tacoma Power. A Tacoma Power Participating Contractor must install the unit, and the unit must be certified by the Air-Conditioning, Heating, and Refrigeration Institute, with a heating rating of 9.0 HSPF or 7.5 HSPF2 and a cooling rating of 15 SEER or 14.3 SEER2. Ductless units must go in the main area of the home. Homes that already got a Tacoma Power heat pump incentive, new construction and do-it-yourself jobs are not eligible. You also need heat load calculations for central and whole-home ductless systems and, for central systems, sizing and balance point calculations. A good contractor handles those, but ask to see them.
The rebate amount depends on what you replace. An existing ductless heat pump is not eligible for a new one under this page. That matters for someone who added a mini-split years ago.
Insulation and window limits
The insulation rebate needs a starting level of R-11 or less in the attic, none in the walls and R-11 or less in the floor. The new levels are R-49 with air sealing in the attic, R-13 in the walls and R-30 in the floor. Manufactured homes, major remodels where building code already forces insulation, new construction, do-it-yourself work and buildings with five or more units are not eligible, and neither are homes that already received an insulation incentive from Tacoma Power. Windows must replace single-pane or double-pane metal-framed windows, and the home's main heat must be electric. The window page lists the same exclusions.
Other help in Tacoma
The State Department of Commerce lists the City of Tacoma and Pierce County as local partners for its home electrification rebates, with awards of $637,000 and $500,000. These go to households at or below 150 percent of area median income, but the state page gives no per-household dollar amount, so ask the City of Tacoma before you plan on it. Our Washington home electrification guide explains how to find your local partner.

Common questions
How much is the Tacoma Power heat pump rebate?
Up to $2,000. A variable-speed heat pump replacing an electric forced-air furnace gets $2,000, and a standard or ductless unit replacing electric heat gets $1,000, with lower amounts in some cases.
Do I need a certain contractor?
Yes. Tacoma Power requires a Participating Contractor for heat pumps, insulation and windows, and does not pay for do-it-yourself work on those.
Can renters get anything?
The EV charging bill credits are open to renters. Most other rebates need the home to be served by Tacoma Power, and the loans need you to own the home and land.
What if my home uses gas?
The insulation, window and loan programs we read require electric main heat. A variable-speed heat pump replacing non-electric heat can still get $1,000.
Does Tacoma Power have a water heater rebate?
Yes, $500 for a Tier 3 or Tier 4 electric hybrid water heater replacing a standard electric one.
