Is the gap worth worrying about?
A 13% gap is meaningful on a project this size — about $1,350. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Seattle.

Heat pump installation by home size: Lacey vs Seattle
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.
| Size | Lacey | Seattle |
|---|---|---|
| 1,000 sq ft (≈2 tons / 1–2 zones) | $5,600–$9,850 | $6,350–$11,200 |
| 1,500 sq ft (≈2.5 tons) | $6,650–$11,450 | $7,550–$13,000 |
| 2,000 sq ft (≈3 tons) | $7,200–$13,100 | $8,150–$14,850 |
| 2,500 sq ft (≈4 tons) | $9,350–$15,200 | $10,600–$17,250 |

Cheapest time for heat pump installation in either city
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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 budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
