Is the gap worth worrying about?

Central AC installation by home size: Bloomington vs Rockford
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 | Bloomington | Rockford |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,300–$7,500 | $4,250–$7,400 |
| 1,500 sq ft (≈2.5 tons) | $4,750–$8,850 | $4,700–$8,750 |
| 2,000 sq ft (≈3 tons) | $5,200–$10,200 | $5,150–$10,100 |
| 2,500 sq ft (≈4 tons) | $6,550–$12,050 | $6,500–$11,900 |
| 3,000+ sq ft (≈5 tons) | $7,950–$14,750 | $7,850–$14,600 |

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
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
The longevity case
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, 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.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
