How much does the electrical add to a heat pump project?

$250 to $900 for a dedicated circuit if your panel has room, and $1,300 to $2,500 if the service panel has to be upgraded to 200 amps. A subpanel, where the service is adequate but the spaces are used up, runs $500 to $1,700.

Do you do the electrical work yourselves?

No. Electrical work on our projects is performed by a licensed electrical contractor, and we say that plainly because it matters legally and practically. Our Washington L&I contractor registration is BELLIHC808NM, there is no electrical contractor licence under it, and we coordinate the electrical trade rather than pretending to be it.

Why do so many Bellingham houses need a panel upgrade?

Because of when they were built. Much of the older housing stock was wired for a household with far fewer electrical loads, and 100-amp panels with no spare spaces are common in anything pre-1960. Subdivisions built from the 1990s onward generally do not have this problem.

Is a panel upgrade rebated?

Not by PSE, and not by any programme with a published amount we can quote. Washington State HEAR does list electric panel and wiring upgrades required for new electric equipment as eligible work. But Commerce distributes it through local administrators who set their own amounts, so there is no statewide schedule to point you at. Ask the local administrator directly. The federal §25C credit, which used to cover panel work, is $0 for 2026.

Can I avoid the panel upgrade by choosing smaller equipment?

Sometimes, and it is worth asking. The compressor itself is a modest load; large electric resistance backup heat is what usually forces the upgrade. A correctly sized cold-climate heat pump at Bellingham’s 19°F design temperature needs less backup than most people assume, and a ductless system with no strip heat at all avoids the question entirely.

Who inspects the electrical work?

The electrical permit and inspection are handled by the electrical contractor, published at $50 to $350 for the permit and $100 to $250 for an inspection where it is billed separately. That is separate from the mechanical permit we pull and the mechanical inspection we attend. Two trades, two permits, one project.

What moves your number

Most impactful first. These are the questions we ask on the phone, and they are the reason a range exists at all.

Whether the panel has a spare space and spare capacity: $250–$900 if it does, $1,300–$2,500 if it does not; These are two completely different jobs that homeowners hear as one. Adding a breaker and running a circuit to an outdoor unit is a few hours of an electrician’s day. Replacing the service panel means coordinating with Puget Sound Energy, a new meter base in some cases, and an inspection, and it is the single biggest swing factor in any Bellingham heat pump quote.
The age of the house, which in Bellingham predicts the panel: pre-1960 stock is where the $1,300–$2,500 line item appears; Bellingham’s 1890s–1930s cottages and four-squares, and its 1950s ramblers, frequently still run 100-amp service, sometimes with a panel that has been full since the 1980s. Houses built from the 1990s onward generally have 200 amps and room to work. The build year tells you which conversation to expect before anyone opens a cover.
Subpanel instead of a full service upgrade: $500–$1,700, and sometimes the right answer; If the service itself has enough capacity but the panel has no physical spaces left, a subpanel adds room for a fraction of the cost of a service upgrade. That is a load-calculation question for the electrician, not a preference. It comes up often in houses where an addition or a shop already consumed the original panel’s spaces.
How far the circuit has to travel, and through what: long runs through finished space add labour and patching; A panel in the garage ten feet from the condenser location is the cheap case. A panel in a basement corner with the only viable condenser pad on the far side of the building means a long run, possibly through finished walls, with drilling and patching behind it. Deciding the outdoor unit location with the electrician present saves real money.
Permit and inspection on the electrical work: $50–$350 for the electrical permit; Electrical permits are published at $50 to $350, and the electrical contractor pulls their own. That is separate from the mechanical permit we pull for the heat pump work. Two permits on one project is normal and it is worth knowing so neither surprises you at signing.
Backup heat strategy, which sets the size of the load: strip heat kits require substantially more capacity than the compressor alone; A heat pump compressor is a modest load. Electric resistance backup heat is not, and specifying a large strip kit is what turns a circuit job into a service upgrade. At Bellingham’s 19°F design temperature a correctly sized cold-climate heat pump needs less backup than people assume, and PSE’s rebates require any electric backup to be locked out by an outdoor sensor, recommended at 35°F or below.

Three worked examples

Same work, three different houses. The arithmetic runs from the installed price, through the programs that apply, to what you write a cheque for.

1998 house, 200-amp panel with four open spaces, single-zone mini split on the garage wall

Installed price: $250–$900 electrical, added to the mini split quote
Rebates applied: No rebate pays for the electrical work itself
PSE electric resistance to heat pump conversion on the mechanical project: $1,500, where the existing heat is electric resistance
Federal §25C: $0
You pay: Electrical stays $250–$900; the mechanical side carries the rebate

The electrical is never rebated on its own. Note that Washington State HEAR does list electric panel and wiring upgrades required for new electric equipment as eligible, but amounts are set per local administrator and are not published, so we do not quote a figure.

1949 Bellingham house, original 100-amp panel, full, adding a two-zone ductless system

Installed price: $1,300–$2,500 for the 200-amp upgrade, plus $250–$900 for the mini split circuit
Rebates applied: PSE conversion rebate on the mechanical work: $1,500
Federal §25C: $0
You pay: Electrical $1,550–$3,400; net project cost reduced by $1,500 on the mechanical side

This is the quote that shocks people, and it is why we get the electrical priced by a licensed electrical contractor before we hand you a mechanical number. A bid that says "electrical not included" is hiding this line, not saving you money.

1962 house, 100-amp service with adequate capacity but no physical breaker spaces

Installed price: $500–$1,700 for a subpanel, plus $250–$900 for the circuit
Rebates applied: Washington State HEAR may cover panel and wiring work required for new electric equipment — amounts set per administrator, not published
Federal §25C: $0
You pay: $750–$2,600 electrical

Worth asking about, because a subpanel is often half the price of a service upgrade and does the same thing for a heat pump. The load calculation decides, and that is the electrician’s call rather than ours.

No example includes a federal tax credit, because there is none to include for a 2026 install. The largest single line in most of these is Puget Sound Energy's $1,500 electric-resistance conversion rebate, which is contractor-gated — PSE requires the installer to be inside its network, so ask us to confirm status for your project before you count on it.
