Central AC installation by home size: Keizer vs Salem
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 | Keizer | Salem |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,850–$8,450 | $4,850–$8,450 |
| 1,500 sq ft (≈2.5 tons) | $5,400–$10,000 | $5,400–$10,000 |
| 2,000 sq ft (≈3 tons) | $5,900–$11,550 | $5,900–$11,550 |
| 2,500 sq ft (≈4 tons) | $7,450–$13,600 | $7,450–$13,600 |
| 3,000+ sq ft (≈5 tons) | $9,000–$16,700 | $9,000–$16,700 |

Cheapest time for central AC installation in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
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
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 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.
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.
