Central AC installation by home size: Des Plaines vs Pittsburgh
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 | Des Plaines | Pittsburgh |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $4,300–$7,550 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $4,800–$8,900 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,100 | $5,250–$10,250 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,250 | $6,600–$12,100 |
| 3,000+ sq ft (≈5 tons) | $9,400–$17,500 | $8,000–$14,850 |

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 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.
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.
If there's one takeaway, it's this: sizing and install quality decide whether an HVAC system performs, not the badge on the box. Get the load calculation right, match efficiency to climate, and take the rebates on offer.
