Central AC installation by home size: Bothell 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 | Bothell | 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
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.

How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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 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.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.
