Is the price difference a dealbreaker?
A 21% gap is meaningful on a project this size — about $1,650. That's real money, but it's often within reach of off-season timing and a tighter apples-to-apples bid in Aurora.

Central AC installation by home size: Aurora vs Peoria
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 | Aurora | Peoria |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $4,200–$7,350 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $4,650–$8,700 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,100 | $5,100–$10,000 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,250 | $6,450–$11,800 |
| 3,000+ sq ft (≈5 tons) | $9,400–$17,500 | $7,800–$14,500 |

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?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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
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.
The budget-first case
Size the system to your home with a Manual J calculation and buy the standard efficiency tier (80% AFUE / 14.3 SEER2). In a mild climate the cheaper unit pays off because you rarely run it hard — paying for premium efficiency you won't use is the most common way to overspend.
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.
