Central AC installation by home size: Bellevue vs Olympia

| Size | Bellevue | Olympia |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,600–$9,800 | $4,950–$8,650 |

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?
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 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 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 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.
