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

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?
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 budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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.
