Central AC installation by home size: Buffalo vs Lewiston
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 | Buffalo | Lewiston |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,300–$7,550 | $4,550–$7,850 |
| 1,500 sq ft (≈2.5 tons) | $4,800–$8,900 | $5,000–$9,300 |
| 2,000 sq ft (≈3 tons) | $5,250–$10,250 | $5,500–$10,750 |
| 2,500 sq ft (≈4 tons) | $6,600–$12,100 | $6,900–$12,650 |
| 3,000+ sq ft (≈5 tons) | $8,000–$14,850 | $8,350–$15,500 |

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?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
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.
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.
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.
