How much should this gap actually matter?
A 13% spread (roughly $1,250) is significant enough to plan around, but not fixed — off-peak timing and sharper bidding in Seattle typically recover some of it.
Central AC installation by type: Lacey vs Seattle
Every central AC installation type gets its own localized price for each metro, using the same labor, climate and permit adjustments — a true apples-to-apples comparison.
| Type | Lacey | Seattle |
|---|---|---|
| 2–3 ton (small home) | $5,500–$8,650 | $6,200–$9,800 |

Central AC installation by home size: Lacey vs Seattle
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 | Seattle |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,950–$8,650 | $5,600–$9,800 |
| 1,500 sq ft (≈2.5 tons) | $5,500–$10,200 | $6,200–$11,550 |
| 2,000 sq ft (≈3 tons) | $6,000–$11,800 | $6,800–$13,350 |
| 2,500 sq ft (≈4 tons) | $7,600–$13,850 | $8,600–$15,750 |
| 3,000+ sq ft (≈5 tons) | $9,150–$17,000 | $10,400–$19,300 |

What hvac pros earn in each metro
Labor is about 60% of a central AC installation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for central AC installation in either city
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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.
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.
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.
