Heat Pump and HVAC Electrical Connections

We wire the breaker, the outdoor shutoff, and the connections for heat pumps, mini-splits, furnaces, and air conditioners, and fit our part around your HVAC contractor's schedule.

Your HVAC contractor sets the heat pump. We bring the power to it. That means a circuit of its own from your breaker box, a shutoff switch outside within sight of the unit, and the connections at both ends, all sized to the numbers on the equipment's nameplate.

Who wires a heat pump, the HVAC crew or the electrician?

On most installs the HVAC crew handles the indoor and outdoor units, the refrigerant lines, and the thermostat. We handle the wiring from the panel, the outdoor shutoff, and any panel work. If you send us their quote or the model number, we can price the electrical side before install day, and we get the electrical permit for our part.

Backup heat and your panel

Many heat pumps have electric backup heat that comes on during the coldest stretches, and it draws far more power than the heat pump itself. That number is what decides whether your panel has room. If it doesn't, a panel upgrade or a service upgrade shows up separately on the estimate, so you can see what the heat pump wiring costs by itself.

Replacing an older furnace or air conditioner

The circuit that ran the old equipment may be the wrong size for the new unit, even when it sits in the same spot. We check the wire and the breaker against the new nameplate before reusing them. Sometimes the trouble with an older system turns out to be electrical. When Rick's HVAC stopped working, the fix was in the breaker box:

… He had to troubleshoot a poor connection somewhere between the breaker box and the HVAC system and ultimately replaced a breaker in the breaker box. …

Mini-splits and rooms the furnace doesn't reach

A ductless mini-split heats and cools one or two rooms, which makes it a common choice for an addition, a converted garage, or an ADU. Each outdoor unit gets its own circuit and shutoff switch. For a single cold bathroom or bedroom, a wall heater is the smaller job.

Utility rebates and loans

If SUB supplies your power and the heat pump replaces an electric forced-air furnace, SUB lists rebates up to $1,500 or a 0% loan up to $7,000, depending on the system. Lane Electric lists an $800 rebate or a 0% loan up to $9,000 for ductless heat pumps. Both have approval steps before the work starts, so call the utility before you sign the HVAC contract. The utility guides link to each program.

Wiring for your new heat pump

Send the heat pump model from your HVAC quote, or your HVAC contractor's contact, and where the outdoor unit will sit.
