Central AC installation by home size: Palo Alto vs San Jose
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 | Palo Alto | San Jose |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,850–$10,200 | $5,850–$10,200 |
| 1,500 sq ft (≈2.5 tons) | $6,500–$12,100 | $6,500–$12,100 |
| 2,000 sq ft (≈3 tons) | $7,100–$13,950 | $7,100–$13,950 |
| 2,500 sq ft (≈4 tons) | $8,950–$16,450 | $8,950–$16,450 |
| 3,000+ sq ft (≈5 tons) | $10,850–$20,200 | $10,850–$20,200 |

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
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?
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 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 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
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.
