Central AC installation by type: Bellevue vs Tri-Cities
We localize each central AC installation type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.
| Type | Bellevue | Tri-Cities |
|---|---|---|
| 2–3 ton (small home) | $6,200–$9,800 | $5,350–$8,400 |
| 3.5–4 ton (mid home) | $8,600–$13,350 | $7,400–$11,500 |
| 5 ton (large home) | $10,950–$19,300 | $9,450–$16,600 |

Central AC installation by home size: Bellevue vs Tri-Cities
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 | Bellevue | Tri-Cities |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,600–$9,800 | $4,850–$8,400 |
| 1,500 sq ft (≈2.5 tons) | $6,200–$11,550 | $5,350–$9,950 |
| 2,000 sq ft (≈3 tons) | $6,800–$13,350 | $5,850–$11,500 |
| 2,500 sq ft (≈4 tons) | $8,600–$15,750 | $7,400–$13,550 |
| 3,000+ sq ft (≈5 tons) | $10,400–$19,300 | $8,950–$16,600 |

What hvac pros earn in each metro
Roughly 60% of what you pay for central AC installation is labor, which is why local wages explain most of the price gap. The numbers below are actual metro wages for skilled installers, sourced from BLS OEWS — not guesses.

Cheapest time for central AC 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 budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
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.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
