Is the gap worth worrying about?
A 16% spread (roughly $1,600) is significant enough to plan around, but not fixed — off-peak timing and sharper bidding in Bothell typically recover some of it.

Heat pump installation by home size: Bothell vs Tri-Cities
Heat pumps are sized in tons like AC (roughly one ton per 500–600 sq ft), but cold-climate models may be sized up for heating. Ductless mini-splits are priced per zone instead.

|---|---|---|
| 1,000 sq ft (≈2 tons / 1–2 zones) | $6,350–$11,200 | $5,450–$9,650 |

What hvac pros earn in each metro
Since labor accounts for around 60% of what a heat pump installation job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

Cheapest time for heat pump installation in either city
A furnace or AC that dies mid-heat-wave gets replaced at whatever the on-call crew charges. One that gets swapped in April or October gets a competitive, unhurried quote instead.
How much should you really budget for HVAC in 2026?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
The efficiency-first case
In a hot-summer or cold-winter region, a higher SEER2/AFUE unit — or a heat pump — earns its premium back in lower bills, and utility and state rebates can still cut into the sticker (the federal 25C/25D credits ended Dec 2025). Run the payback math before defaulting to the cheapest box.
The longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
The brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
