Central AC installation by home size: Annandale vs Buffalo
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.

|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,900 | $4,300–$7,550 |
| 1,500 sq ft (≈2.5 tons) | $5,650–$10,550 | $4,800–$8,900 |
| 2,000 sq ft (≈3 tons) | $6,200–$12,150 | $5,250–$10,250 |
| 2,500 sq ft (≈4 tons) | $7,850–$14,350 | $6,600–$12,100 |
| 3,000+ sq ft (≈5 tons) | $9,450–$17,550 | $8,000–$14,850 |

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 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 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 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.
If there's one takeaway, it's this: sizing and install quality decide whether an HVAC system performs, not the badge on the box. Get the load calculation right, match efficiency to climate, and take the rebates on offer.
