Central AC installation by home size: Hillsboro vs Lake Oswego

|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $5,100–$8,850 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $5,600–$10,450 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,050 | $6,150–$12,050 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,200 | $7,750–$14,200 |
| 3,000+ sq ft (≈5 tons) | $9,350–$17,400 | $9,350–$17,400 |

Cheapest time for central AC installation in either city
Demand for HVAC work falls off a cliff in the shoulder months, and contractors discount to keep their crews booked. Wait for a 100-degree day or a hard freeze, though, and you're paying emergency rates for a system that just quit.
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 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 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.
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.
