By size

Central AC installation by home size: Green Bay vs Milwaukee

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)$4,250$7,400$4,700$8,200
1,500 sq ft (≈2.5 tons)$4,700$8,750$5,200$9,700

Editors' roundtable

How much should you really budget for HVAC in 2026?

What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.

The efficiency-first case

High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.

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.

Our take

Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
