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

What hvac pros earn in each metro
About 60% of a central AC installation bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.

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?
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 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 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 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.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
