Is the price difference a dealbreaker?
3% is within noise for central AC installation — contractor selection and timing move the price more than which of these two metros you're in.

Central AC installation by home size: Beloit vs Madison
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 | Beloit | Madison |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,250–$7,450 | $4,350–$7,600 |
| 1,500 sq ft (≈2.5 tons) | $4,700–$8,800 | $4,850–$9,000 |
| 2,000 sq ft (≈3 tons) | $5,150–$10,150 | $5,300–$10,400 |
| 2,500 sq ft (≈4 tons) | $6,550–$11,950 | $6,700–$12,250 |
| 3,000+ sq ft (≈5 tons) | $7,900–$14,650 | $8,100–$15,050 |

Cheapest time for central AC installation in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
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 budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
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 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 brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
