Central AC installation by home size: Mountain View vs San Francisco

| Size | Mountain View | San Francisco |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,850–$10,200 | $5,650–$9,850 |
| 1,500 sq ft (≈2.5 tons) | $6,500–$12,100 | $6,250–$11,650 |
| 2,000 sq ft (≈3 tons) | $7,100–$13,950 | $6,850–$13,450 |
| 2,500 sq ft (≈4 tons) | $8,950–$16,450 | $8,650–$15,850 |

Cheapest time for central AC installation in either city
Installers cut prices in spring and fall because job volume drops and crews sit idle — the opposite happens during a summer heat wave or winter cold snap, when a dead system forces homeowners into a full-price emergency swap.
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
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
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
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 brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
