How much should this gap actually matter?
3% is within noise for central AC installation — contractor selection and timing move the price more than which of these two metros you're in.
Central AC installation by type: Lacey vs Spokane

Central AC installation by home size: Lacey vs Spokane
Central AC is sized in tons of cooling — about one ton per 500–600 sq ft. Undersizing leaves you hot; oversizing short-cycles and wastes money, so a Manual J load calculation matters.
| Size | Lacey | Spokane |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,950–$8,650 | $4,800–$8,350 |
| 1,500 sq ft (≈2.5 tons) | $5,500–$10,200 | $5,300–$9,900 |
| 2,000 sq ft (≈3 tons) | $6,000–$11,800 | $5,800–$11,400 |
| 2,500 sq ft (≈4 tons) | $7,600–$13,850 | $7,350–$13,450 |
| 3,000+ sq ft (≈5 tons) | $9,150–$17,000 | $8,900–$16,500 |

Cheapest time for central AC installation in either city
Why spring and fall are cheaper: contractors have open calendar space and compete harder for the work. Why summer and deep winter are expensive: a broken system in extreme weather isn't optional, so you lose your negotiating leverage.
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 most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
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.
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.
