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

What hvac pros earn in each metro

Cheapest time for central AC installation in either city
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
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
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 longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, 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 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.
