Central AC installation by home size: Janesville vs Pittsburgh
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 | Janesville | Pittsburgh |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,250–$7,450 | $4,300–$7,550 |
| 1,500 sq ft (≈2.5 tons) | $4,700–$8,800 | $4,800–$8,900 |
| 2,000 sq ft (≈3 tons) | $5,150–$10,150 | $5,250–$10,250 |
| 2,500 sq ft (≈4 tons) | $6,550–$11,950 | $6,600–$12,100 |
| 3,000+ sq ft (≈5 tons) | $7,900–$14,650 | $8,000–$14,850 |

How much should you really budget for HVAC in 2026?
Get the sizing wrong or the efficiency tier mismatched to your climate, and the price drifts fast in either direction. Below, a look at how those choices — plus brand markup — shape the real number.
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.
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 costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
