Issaquah and Sammamish quotes look different from the ones we write in the south end, and it is not because Eastside homeowners get charged an Eastside tax. It is because the houses are bigger, the lots are steeper, and a lot of them were built with an air handler and no cooling at all. Here are the real 2026 numbers and what actually moves them.
The price ranges, plainly
All figures are installed cost — equipment, labor, materials, permit, startup.
| System | Standard range | Larger / premium homes |
|---|---|---|
| SystemDucted heat pump | Standard range$12,000 – $18,000 | Larger / premium homes$13,800 – $24,300 |
| SystemDuctless mini-split | Standard range$8,000 – $14,000 | Larger / premium homes$9,200 – $18,900 |
| SystemHeat pump replacement (like-for-like) | Standard range$10,000 – $16,000 | Larger / premium homes$11,500 – $21,600 |
| SystemHeat pump repair | Standard range$150 – $1,500 | Larger / premium homes$175 – $2,000 |
A ducted heat pump is the default answer for most homes in these two cities, because most of them already have ductwork worth reusing. The honest framing: the $12,000 figure is a real starting point for a modest, straightforward home, and a 3,400 square foot two-story on the plateau with a variable-speed system and a difficult outdoor location is not going to land there. Both ends of that table are real jobs.

Why Eastside numbers skew toward the top of the range
Square footage drives tonnage
Heat pumps are priced by capacity. A 1,500 square foot rambler might need 2 to 2.5 tons. A 3,200 square foot two-story with vaulted ceilings and a walkout basement can need 4 to 5. That is a bigger outdoor unit, a bigger air handler, larger circuits, and more refrigerant — several thousand dollars of difference before anyone touches a wrench.
Two stories means the upstairs problem
The most common complaint we hear from Sammamish and Issaquah Highlands homeowners is the bedrooms upstairs run hot in July and cold in January. That is usually undersized return air, not undersized equipment. Fixing it during the install — adding a return, resizing a trunk, or adding a zone — is money well spent, and it belongs on the estimate up front rather than as a surprise afterward.
Hillside and wooded lots complicate placement
Steep side yards, retaining walls, tight setbacks to a neighbor's property line, and long runs from the equipment location to the electrical panel all add labor. So does building a level pad on a slope. None of it is exotic, but it is hours.
Newer homes are not automatically simpler
A 1998 to 2010 build usually has decent ductwork and a clean mechanical closet, which helps. But many of them also have a gas furnace paired with an aging AC condenser, so the conversation becomes whether to replace both with one heat pump or keep the furnace as backup. More on that below.
What each dollar is actually buying
- Load calculation. A real Manual J against the code winter design temperature for your address — not a rule of thumb per square foot. Oversized systems short-cycle, dehumidify poorly and wear out early.
- Equipment tier. Single-stage at the value end, two-stage in the middle, variable-speed at the top. On the Eastside the variable-speed upgrade is worth more than usual, because bigger homes benefit most from long, low, quiet run cycles.
- Ductwork condition. Reusable ducts keep you in the base range. Crushed, disconnected, or badly undersized runs need work, and duct modification is typically a $3,000 to $8,000 scope on its own if the whole system needs replacing.
- Electrical. Most homes with a 100-amp panel or larger absorb a heat pump without a panel upgrade. Older or already-full panels are the exception, and that scope goes to a licensed electrician.
- Permit and inspection. Pulled on every job, no exceptions. Skipping it can complicate a home sale later, since Washington's seller disclosure asks about unpermitted work directly.
Rebates: the meter decides, not the city limits
Issaquah and Sammamish are Puget Sound Energy territory for both electricity and natural gas, which puts most homes here in the PSE rebate lane. The sitewide framing applies: up to $4,400 toward a qualifying heat pump when it replaces an existing electric or fossil-fuel system, with the exact amount depending on what you are replacing and what you install.
Two things every Eastside homeowner should know before budgeting around a rebate:
- The federal 25C tax credit ended December 31, 2025. No 2026 installation qualifies. Anyone still quoting it is working from stale paperwork.
- Since April 2, 2026, PSE rebates require a PSE-certified installer. Varsity is a PSE Certified Contractor, and we file the paperwork as part of the job. If you hire someone who is not certified, the rebate is simply gone.
Programs change, so we confirm your current eligibility against your actual utility account rather than assuming. The full breakdown lives in our PSE heat pump rebate guide.
Ducted, ductless, or hybrid?
Ducted wins when the existing duct system is in reasonable shape. It is invisible, it conditions the whole house from one thermostat, and it is the cleanest swap for a home that already has a furnace and coil in a closet or garage.
Ductless earns its keep in three Eastside situations: an older Issaquah home near Front Street with no ducts at all, a bonus room or shop over the garage that the main system never reaches, and an ADU or basement apartment that needs its own controls. A single-zone mini-split starts around $8,000; multi-zone systems climb from there based on head count.
Hybrid — heat pump plus the existing gas furnace as backup — makes sense when that furnace is young and healthy. Keeping it costs nothing extra and gives you a second heat source. If the furnace is 15-plus years old, you are better off retiring it and letting the heat pump carry the house with electric backup.
What we do at the estimate
A technician measures the home, runs the load calculation, inspects the ducts and the panel, looks hard at where the outdoor unit can legally and quietly live, and leaves you with written Good, Better and Best pricing. It is a sales appointment — we are there to earn the job — but there is no manufactured urgency and no one-night-only pricing. If the right answer is a repair or waiting a season, we say so.
Every installation carries a 10-year parts and labor warranty, most are finished in one day, and the permit and rebate paperwork are ours to handle.
