Is the gap worth worrying about?
At 3%, this gap is small enough that it's usually swallowed by normal quote-to-quote variation for central AC installation — focus on the contractor, not the city.
Central AC installation by type: Olympia vs Spokane

Localized 2026 planning estimates — not quotes. Each city adjusts the national central AC installation range for local labor, climate and permits.
Central AC installation by home size: Olympia 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 | Olympia | 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 |
Treat these as 2026 localized estimates for central AC installation, not quotes from a contractor.
Cheapest time for central AC installation in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
How much should you really budget for HVAC in 2026?
Get the sizing wrong or the efficiency tier mismatched to your climate, and the price drifts fast in either direction. Below, a look at how those choices — plus brand markup — shape the real number.
The longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
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 efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
