Is the gap worth worrying about?
That 4% gap is small — for central AC installation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

Central AC installation by home size: Hillsboro vs Keizer
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 | Hillsboro | Keizer |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,100–$8,850 | $4,850–$8,450 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,450 | $5,400–$10,000 |
| 2,000 sq ft (≈3 tons) | $6,150–$12,050 | $5,900–$11,550 |
| 2,500 sq ft (≈4 tons) | $7,750–$14,200 | $7,450–$13,600 |
| 3,000+ sq ft (≈5 tons) | $9,350–$17,400 | $9,000–$16,700 |

What hvac pros earn in each metro

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 efficiency-first case
Where you face brutal summers or hard winters, a higher SEER2/AFUE system or a heat pump runs enough hours to claw back its premium through lower bills — and utility or state rebates can still trim the sticker even though the federal 25C/25D credits closed at the end of 2025. Do the payback arithmetic before you reach for the cheapest box on the lot.
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 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.
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.
