Quick answerHeat pump installation in Spokane means choosing a cold-climate model or a dual-fuel pairing with a gas furnace, sizing it from a load calculation, setting the outdoor unit on a raised stand above snow, and configuring the thermostat's backup heat lockout. A replacement install usually takes one to two days, plus the Washington mechanical permit.

Heat pumps built for a real winter
Standard heat pumps lose capacity as the outdoor temperature falls, which is why older ones earned a bad name in cold places. Cold-climate models use variable-speed compressors that keep producing useful heat well below zero, and dual-fuel systems let a gas furnace carry the coldest hours while the heat pump handles the rest.
We size from a load calculation and set the outdoor unit on a stand above the snow line, with room for defrost water to drain. The thermostat is configured so backup heat only runs when it is needed. That setup is the difference between a heat pump that saves money and one that runs on strip heat half the winter.
What drives heat pump installation cost
Planning range: Cost data from 226 Spokane-area projects puts a typical heat pump install around $5,198 to $6,838, with jobs ranging from about $2,739 to $9,863. These are published market figures from 2026-04, given for planning, with the on-site estimate as the real price.
Heat pump setups for Spokane homes
Cold-climate heat pumps
A cold-climate heat pump keeps most of its heating capacity down into single digits and still heats below zero, which covers nearly every hour of a Spokane winter. These units use variable-speed inverter compressors that ramp down on mild days and up on cold ones. We pair them with electric backup heat or an existing furnace and set the lockout temperatures from the model's rated performance. The outdoor unit goes where drifting snow and roof runoff will not bury it.
Dual-fuel heat pump and furnace systems
Dual fuel keeps the gas furnace and adds a heat pump in place of the air conditioner. The heat pump heats the house through fall, spring and milder winter days, and the furnace takes over below a changeover temperature. It is a strong choice for Spokane because it covers the coldest nights with gas and uses electricity efficiently the rest of the time. We set the changeover based on your equipment and whether you care more about comfort or operating cost.
Replacing an AC with a heat pump
When a central air conditioner reaches the end of its life, replacing it with a heat pump costs somewhat more than another AC and adds heating to the same equipment. The indoor coil is replaced with a matched heat pump coil, the thermostat is upgraded to one that controls both, and the furnace stays as the backup. For many homes that already have a furnace in good shape, this is the lowest-risk way to start using a heat pump.
Which heat pump setup fits your home
| Cold-climate all-electric | Dual fuel | Standard with electric backup | |
|---|---|---|---|
| Coldest-night heat | Heat pump plus electric strips | Gas furnace | Mostly electric strips |
| Needs gas | No | Yes | No |
| Operating cost in deep cold | Moderate | Low to moderate | High |
| Best for | Homes without gas | Homes with a good furnace | Mild climates, not Spokane |
Sizing heat pumps for Spokane weather
Spokane temperatures run from about 26 to 88 degrees across a typical year, but severe winters can reach minus 10. That is why standard heat pumps are not recommended here as a sole heat source, and cold-climate or dual-fuel setups are. Washington also requires a mechanical permit even for like-for-like HVAC replacement, and 2026 equipment reflects the shift to A2L refrigerants, which affects which coils and line sets can be reused.

Heat pump installation questions
Will a heat pump keep my Spokane house warm?
A cold-climate model or a dual-fuel setup will. A standard heat pump alone struggles on the coldest nights, so we do not install it as the only heat here.
Should I keep my gas furnace?
If it is in good shape, dual fuel is often the best value: the heat pump handles most of the season and the furnace covers the deep cold.
Are there rebates for heat pumps?
Utility programs from Avista and other local utilities have offered rebates on qualifying equipment. Programs change, so check before you buy. The federal 25C credit ended after 2025.
How long does a heat pump install take?
Usually one to two days, depending on whether ductwork or electrical changes are needed.
What does a heat pump cost in Spokane?
Local project data puts a typical install around $5,198 to $6,838, with a wider range from about $2,739 to $9,863. Your quote depends on size, model and what the house needs.
