Central AC installation by home size: Champaign vs Chicago
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 | Champaign | Chicago |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,250–$7,400 | $5,100–$8,850 |
| 1,500 sq ft (≈2.5 tons) | $4,700–$8,750 | $5,600–$10,450 |
| 2,000 sq ft (≈3 tons) | $5,150–$10,100 | $6,150–$12,100 |
| 2,500 sq ft (≈4 tons) | $6,500–$11,900 | $7,750–$14,250 |
| 3,000+ sq ft (≈5 tons) | $7,850–$14,600 | $9,400–$17,500 |

Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
How much should you really budget for HVAC in 2026?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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
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 costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
