Heat Pump Installation — Greater Seattle
Most heat pump installations in Greater Seattle run $6,500–$15,500 depending on system type and home size. SPS Pro Services installs ducted and ductless heat pumps across King and Snohomish counties, sized for our mild, wet climate and matched to your existing ductwork or a new mini-split layout.

A heat pump installation includes load calculations, equipment selection, refrigerant line and electrical work, and either ductwork tie-in or ductless head placement. Homeowners typically need this when replacing an aging furnace or AC, adding cooling to a home that's never had it, or cutting reliance on baseboard electric heat. Western Washington's mild winters and increasingly warm summers make heat pumps a practical single-system solution for both.

No surprises
How a heat pump installation visit works
1
Home evaluation and load calculation
A technician inspects existing ductwork or wall space, checks your electrical panel capacity, and calculates heating and cooling load for your home's square footage and insulation.
2
System recommendation
Based on the evaluation, we recommend ducted, ductless, or a hybrid setup and walk through equipment tiers and what's included at each price point.
3
Electrical and line set preparation
Our electricians run any needed circuits and disconnects while refrigerant line sets are routed between the outdoor unit and indoor air handler or heads.
4
Equipment installation
The outdoor condenser and indoor unit or units are mounted, connected, and the refrigerant system is evacuated and charged to manufacturer spec.
5
Startup, testing, and walkthrough
We test heating and cooling modes, check airflow at each register or head, verify thermostat operation, and review basic maintenance with you before closing out the job.
Why quotes range from $6,500 to $15,500
These factors decide where your job lands in the range — and we walk you through each one on the written quote.
- Ducted versus ductless configuration and number of indoor zones or heads needed
- Whether existing ductwork can be reused or needs modification
- Electrical panel upgrades if your home's current service can't support the new unit

Straight answers
Heat Pump Installation questions we hear most
Do heat pumps work in Seattle's winters?
Yes. Modern cold-climate heat pumps maintain efficient output well below freezing, and Puget Sound winters rarely drop into the range where that becomes an issue. Most homes here run on heat pump heat alone without a backup source.
Ducted or ductless, which should I choose?
If your home already has ductwork in good condition, a ducted heat pump usually integrates faster and costs less. Homes without ducts, additions, or older houses with limited attic access often do better with a ductless mini-split system.
How long does installation take?
A straightforward ducted swap typically takes one to two days. Ductless systems with multiple zones, or jobs requiring electrical panel work, can run two to four days depending on scope.
Will a heat pump lower my electric bill?
If you're replacing electric baseboard heat or an older AC-plus-furnace setup, most homeowners see lower combined heating and cooling costs, since a heat pump moves heat rather than generating it. Actual savings depend on your utility rates with PSE or Snohomish PUD and your home's insulation.
