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: Kennewick vs Tacoma
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 | Kennewick | Tacoma |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,850–$8,400 | $5,600–$9,800 |
| 1,500 sq ft (≈2.5 tons) | $5,350–$9,950 | $6,200–$11,550 |
| 2,000 sq ft (≈3 tons) | $5,850–$11,500 | $6,800–$13,350 |
| 2,500 sq ft (≈4 tons) | $7,400–$13,550 | $8,600–$15,750 |
| 3,000+ sq ft (≈5 tons) | $8,950–$16,600 | $10,400–$19,300 |

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?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
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 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
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.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
