How much does a heat pump or 240V circuit cost?

This range is an estimate. No published table was read for it. The typical SoCal range is $1,500 to $6,000 as of October 2026, and the wide spread has one cause: whether the panel can take the new load.

Circuit sizing from the nameplate is on the heat pump and appliance circuits page.

The circuit itself

A heat pump needs a dedicated circuit, a disconnect near the outdoor unit and the right wire. For many systems there is also a circuit for the indoor air handler, and sometimes for electric backup heat. The electrician runs the cable or conduit, sets the breaker and disconnect, connects the equipment and has the work inspected. If the panel has room and the run is short, this is near the low end of the range.

A spa is another 240V load, and its price is on the hot tub and pool wiring cost page.

For comparison, Fixr lists $100 to $150 for a 20-amp outlet. A heat pump circuit costs more because the load is larger, the equipment is outdoors and a disconnect is required.

Panel capacity: the swing factor

A heat pump pulls real power. If the house also has an EV charger, an electric range or a dryer, the main service can run out of headroom. The electrician checks with a load calculation. Three outcomes are common:

1. There is room. The job is the circuit and disconnect.
2. The panel is full but the service is enough. A subpanel or tandem breakers may solve it.
3. The service is too small. A panel upgrade comes first, and that raises the total toward the top of the range.

Smart electrical panels and load-limiting devices can sometimes avoid a service upgrade, with their own cost and approval rules. The load calculation guide shows the math, and the heat pump electrical guide lists what each system type needs.

Who does what

The HVAC contractor sells and installs the heat pump. The electrician handles the supply side. Quotes often split along that line. Make sure someone owns the disconnect, the thermostat wiring and the permit, and that the two quotes do not overlap or leave a gap. The electrification order guide explains what to do first when you are converting several things.

Incentives as of October 2026

The federal energy-efficient home improvement credit (25C) has ended for new 2026 installs. For state money, the TECH Clean California page showed heat pump incentives reserved statewide with waitlists as of its last update, and the program does not list per-unit amounts on that page. Check current status before signing, and do not price your decision around a rebate.

Permits and fees

A new 240V circuit, disconnect or panel change needs an electrical permit. HVAC replacement often adds a mechanical permit. Fees differ. Riverside’s FY 2026-27 schedule lists a $41.00 electrical issuance fee, for example, and other cities charge differently. Look at the page for your city, such as Riverside, and the permits guide.

How to compare quotes

• Ask for the load calculation, not just a statement that a new panel is needed.
• Ask for the circuit, disconnect and any panel work as separate lines.
• Ask who files the electrical and mechanical permits.
• Ask what the price would be for a non-upgrade option, such as load management.
• Use the quote checklist.

What is not included
