Heat pumps in Gig Harbor, WA
A heat pump heats and cools with one system by moving heat between indoors and out. On the Gig Harbor peninsula, where many homes still heat with electric baseboards or electric furnaces, it is usually the single biggest step toward lower heating bills. Home Comfort Alliance installs, repairs and maintains ducted, ductless and dual-fuel heat pumps here from our Sumner branch. Call (425) 645-0404 for a free installation estimate.
Most of the peninsula gets electricity from Peninsula Light, the local member-owned co-op (Peninsula Light Company). PenLight offers heat pump incentives to members, installed by qualified contractors, and Home Comfort Alliance is on its list of ductless and standard heat pump contractors (PenLight heat pump incentives and contractor list).
PenLight heat pump incentives for Gig Harbor and Key Peninsula homes (checked October 2026)
Peninsula Light (PenLight) pays incentives to members who install a qualifying ducted or ductless heat pump: $600 to $1,700 for a ducted system and $1,000 for ductless, depending on the heat you replace, and up to $9,000 for income-qualified members with pre-approval. Home Comfort Alliance is on PenLight's ductless and standard heat pump contractor lists.
| Your project | PenLight incentive |
|---|---|
| Variable-speed heat pump replacing an older heat pump, a gas or oil furnace, or electric baseboard or wall heat | $600 |
| Heat pump replacing an electric forced-air furnace | $1,200 |
| Variable-speed heat pump replacing an electric forced-air furnace | $1,700 |
| Ductless heat pump (electric baseboard, wall heaters or an electric furnace heat the home today) | $1,000 |
| Income-qualified ducted heat pump (pre-approval required) | $9,000 |
| Income-qualified ductless heat pump (pre-approval required) | $6,000 |

Who qualifies
- You are a PenLight member, in an existing single-family home, manufactured home or condo (buildings of up to four units). New construction does not qualify.
- Ductless: electric heat (baseboard, wall heaters or an electric forced-air furnace) is your main heat today. PenLight pays one ductless incentive per residential meter.
- Income-qualified amounts: you need PenLight's pre-approval and enrollment in a PenLight income-based billing program before the installation.
Equipment rules
- HSPF2 7.5 or higher and SEER2 14.3 or higher, with an AHRI certificate for the matched system.
- Variable-speed incentives need the manufacturer's documentation that the system is variable speed.
- A licensed HVAC contractor with a refrigerant certificate installs ductless systems. PenLight lists the contractors its members use most and says other licensed and bonded contractors may also qualify.
How it works with us
- Free in-home estimate with a room-by-room load calculation (ACCA Manual J).
- We choose equipment that meets PenLight's efficiency rules and show you the AHRI match.
- Income-qualified? Get PenLight's pre-approval before the work starts.
- We install the system and pull the required permits.
- We give you an invoice showing the installed make and model numbers and the heat source you had before. You send it, with the rest of your project documentation, to PenLight's energy specialist.
PSE customers on the peninsula
Some peninsula homes buy natural gas from PSE. PSE gas customers who add a ducted heat pump to a gas furnace can get PSE's $1,500 hybrid heat pump rebate, or up to $2,400 through Efficiency Boost if income-qualified (PSE hybrid heat pump rebate). PSE's $1,500 electric heat conversion rebate applies only where PSE, not PenLight, supplies your electricity (PSE electric resistance to heat pump rebate). The City of Gig Harbor's utility page shows which company serves your address (City of Gig Harbor, local utility providers). For every utility we serve, see our heat pump rebates hub.
PenLight's heat pump water heater offer
PenLight sells a heat pump water heater through its online store with an $1,800 instant rebate for a limited time, or $3,000 for pre-approved income-qualified members. The unit is delivered to the curb; installation is not included (PenLight heat pump water heater incentives). For water heater options, see our water heater services.
The federal 25C tax credit ended for equipment installed after December 31, 2025, so it no longer adds to these amounts.

The right setup for your house
Gig Harbor’s housing ranges from cottages and older harbor homes to hillside view homes and new subdivisions, and the best heat pump layout follows the house:
| Your home | Usual recommendation |
|---|---|
| Baseboards or wall heaters, no ducts | Ductless heads in the main living areas and bedrooms, on one or two outdoor units |
| Electric furnace with ducts | Ducted heat pump and new air handler, reusing the ducts |
| PSE gas furnace | Dual fuel: heat pump for mild weather and cooling, furnace for cold snaps |
| Propane furnace | Dual fuel with a heat pump carrying most of the load, or all-electric |
| Large view home with zones | Ducted system for the main floors plus ductless heads for rooms with heavy sun or no ducts |
Ducted or ductless: how to decide
Both are heat pumps; the difference is how the conditioned air gets to the rooms. A ducted system uses ductwork and one air handler, with only vents and a thermostat visible, and filters the whole house through one filter. It makes sense when the home already has ducts in good shape. A ductless system puts an indoor head in each zone, connected to the outdoor unit by a small line set, so each room can run at its own temperature and there are no duct losses. It makes sense in homes heated by baseboards, in additions, and in rooms the ducts never reached. Many Gig Harbor homes end up with a mix: ducted for the main floors, ductless for a sunroom or bonus room.
Running costs and savings
A heat pump delivers more heat energy than the electricity it uses, which is why switching from electric baseboards or an electric furnace usually lowers heating bills noticeably. How much you save depends on the home’s insulation, the efficiency of the equipment (HSPF2 for heating, SEER2 for cooling), how the thermostat is set, and how often backup heat runs. We show the running cost difference between efficiency levels on your estimate, so you can see whether a higher-efficiency model is worth its price for your house.

Coastal conditions
Two things set peninsula installs apart. First, salt air: close to the shoreline, outdoor coils and connections corrode faster, so we favor units with protective coil coatings, place units out of direct spray and prevailing wind where possible, and recommend occasional freshwater rinsing. Second, wind and rain: outdoor units go on raised pads or wall brackets, line sets are sealed where they enter the house, and condensate and defrost water are routed away from walkways and foundations.
Cold snaps and backup heat
Gig Harbor winters are cool and wet rather than extremely cold, which suits heat pumps well. For the occasional hard freeze, every system is designed with backup: electric strips in the air handler for all-electric homes, or the furnace in dual-fuel setups. We size to your home’s heat loss so backup runs rarely, and set the thermostat so it does not switch on every morning after a setback.
Electrical planning
A heat pump needs a dedicated 240-volt circuit and an outdoor disconnect, and backup heat strips add more load. Our electricians check the panel with a load calculation before the heat pump is quoted, and coordinate any service upgrade with PenLight or PSE. Because the HVAC and electrical work are in the same estimate, there are no surprises between the two, and the whole job is scheduled so the system can be started and inspected in one visit.
Install day and permits
Inside city limits, the City of Gig Harbor issues the mechanical permit (City of Gig Harbor, building permits, forms and fees); outside them, Pierce County does. The new circuit needs an L&I electrical permit (L&I, cities that do their own electrical permits). We file both. A ducted install usually takes one to two days, and a single-zone ductless system about one day. Before we leave, the lines are pressure-tested and evacuated, charge and airflow verified, and the thermostat or remotes set up with you.
Heat pump service
We repair and maintain ducted and ductless heat pumps: capacitors and contactors, refrigerant leaks, defrost controls, reversing valves, fan motors and ductless drain lines. A fall check before heating season is the most important visit, since a heat pump runs most of the year here. Between visits, clean or replace filters regularly, rinse ductless head filters monthly in heavy use, and keep leaves, needles and plants at least two feet from the outdoor unit so it can breathe.
Warranty and Home Comfort Club
We support the manufacturer’s warranty on covered equipment parts. New heat pump installations come with a 3-year Comfort Shield labor warranty, kept active with yearly maintenance. First-year maintenance is included.
Home Comfort Club is a monthly membership starting at $15 a month. Home Comfort Club members with a new system installed by Home Comfort Alliance get extended labor coverage for up to 5 years from installation. Ask your technician or comfort advisor for the current plan details.
Gig Harbor heat pump FAQ
Does PenLight offer heat pump rebates?
Yes. Peninsula Light pays incentives to members for qualifying ducted and ductless heat pumps, with higher amounts for income-qualified members who get pre-approval. Amounts run from $600 to $1,700 for ducted systems and $1,000 for ductless, checked October 2026. Home Comfort Alliance is on PenLight’s ductless and standard heat pump contractor lists.
Does a ductless mini-split qualify for a PenLight incentive?
Yes, when electric baseboard, wall heaters, plug-in heaters or an electric forced-air furnace is your main heat today. PenLight allows one ductless incentive per meter, and a licensed HVAC contractor must install it.
I heat with gas or oil. Can I get a PenLight incentive?
Yes. PenLight pays its $600 upgrade incentive for a variable-speed ducted heat pump that replaces a gas or oil furnace.
Do I need a PenLight-listed contractor?
PenLight lists the contractors its members use most and says other licensed and bonded contractors may also qualify. Ask your contractor to confirm PenLight’s requirements before installation. Home Comfort Alliance is on both of PenLight’s heat pump contractor lists.
What do I send PenLight?
An invoice showing the installed make and model numbers and the heat source you had before, sent to PenLight’s energy specialist. Income-qualified incentives need pre-approval before the work starts.
How much does a heat pump cost in Gig Harbor?
Seattle-area data puts ducted heat pumps between about $3,160 and $20,000 depending on efficiency, averaging about $10,218, before incentives (Angi, July 2026). Single-zone ductless systems run $2,222 to $5,555.
Can a heat pump replace my baseboard heat?
Yes. A ductless system with heads in the main rooms can take over most of the heating from baseboards and add cooling.
Do heat pumps hold up near salt water?
Yes, with the right choices: coated coils, sheltered placement and occasional freshwater rinsing of the outdoor coil.
Do I need a permit for a heat pump in Gig Harbor?
Yes: the City of Gig Harbor or Pierce County for the mechanical permit, depending on your address, and L&I for the electrical permit.
Is there a PSE rebate on the peninsula?
For PSE gas customers adding a heat pump to a gas furnace, yes. PSE’s electric heat conversion rebate applies only where PSE supplies your electricity.
What warranty comes with your work?
We support the manufacturer’s warranty on covered equipment parts. New installations come with a 3-year Comfort Shield labor warranty, kept active with yearly maintenance, and first-year maintenance is included. Home Comfort Club members with a new system installed by Home Comfort Alliance get extended labor coverage for up to 5 years from installation.
