Central AC installation by home size: Eugene vs Lake Oswego

| Size | Eugene | Lake Oswego |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,850–$8,450 | $5,100–$8,850 |
| 1,500 sq ft (≈2.5 tons) | $5,400–$10,000 | $5,600–$10,450 |
| 2,000 sq ft (≈3 tons) | $5,900–$11,550 | $6,150–$12,050 |
| 2,500 sq ft (≈4 tons) | $7,450–$13,600 | $7,750–$14,200 |

How much should you really budget for HVAC in 2026?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
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.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
