Localized 2026 planning estimates — not quotes. Each city adjusts the national central AC installation range for local labor, climate and permits.
Is the price difference a dealbreaker?
That 1% 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 type: Medford vs Salem
We localize each central AC installation type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.

Central AC installation by home size: Medford 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 | Medford | Salem |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,900–$8,500 | $4,850–$8,450 |
| 1,500 sq ft (≈2.5 tons) | $5,400–$10,050 | $5,400–$10,000 |
| 2,000 sq ft (≈3 tons) | $5,900–$11,600 | $5,900–$11,550 |
| 2,500 sq ft (≈4 tons) | $7,500–$13,700 | $7,450–$13,600 |
| 3,000+ sq ft (≈5 tons) | $9,050–$16,800 | $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?
Get the sizing wrong or the efficiency tier mismatched to your climate, and the price drifts fast in either direction. Below, a look at how those choices — plus brand markup — shape the real number.
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 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 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.
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.
