Central AC installation by home size: Medford vs Portland
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 | Medford | Portland |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,900–$8,500 | $5,100–$8,850 |
| 1,500 sq ft (≈2.5 tons) | $5,400–$10,050 | $5,600–$10,450 |
| 2,000 sq ft (≈3 tons) | $5,900–$11,600 | $6,150–$12,050 |
| 2,500 sq ft (≈4 tons) | $7,500–$13,700 | $7,750–$14,200 |
| 3,000+ sq ft (≈5 tons) | $9,050–$16,800 | $9,350–$17,400 |

What hvac pros earn in each metro
Labor is about 60% of a central AC installation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

Cheapest time for central AC installation in either city
Why spring and fall are cheaper: contractors have open calendar space and compete harder for the work. Why summer and deep winter are expensive: a broken system in extreme weather isn't optional, so you lose your negotiating leverage.
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 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 budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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.
