Central AC installation by home size: Chicago vs Elgin
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 | Chicago | Elgin |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $5,100–$8,850 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $5,600–$10,450 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,100 | $6,150–$12,100 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,250 | $7,750–$14,250 |
| 3,000+ sq ft (≈5 tons) | $9,400–$17,500 | $9,400–$17,500 |

Cheapest time for central AC installation in either city

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 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
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 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.
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.
