How much should this gap actually matter?

Central AC installation by home size: Joliet vs Normal
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 | Joliet | Normal |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $4,300–$7,500 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $4,750–$8,850 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,100 | $5,200–$10,200 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,250 | $6,550–$12,050 |
| 3,000+ sq ft (≈5 tons) | $9,400–$17,500 | $7,950–$14,750 |

Cheapest time for central AC installation in either city
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?
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
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
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 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.
