Central AC installation by home size: Oceanside vs San Francisco
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.

|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,200–$9,100 | $5,650–$9,850 |
| 1,500 sq ft (≈2.5 tons) | $5,750–$10,750 | $6,250–$11,650 |
| 2,000 sq ft (≈3 tons) | $6,300–$12,400 | $6,850–$13,450 |
| 2,500 sq ft (≈4 tons) | $8,000–$14,600 | $8,650–$15,850 |
| 3,000+ sq ft (≈5 tons) | $9,650–$17,900 | $10,450–$19,500 |

How much should you really budget for HVAC in 2026?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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 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.
Get the sizing and the commissioning right and the brand debate mostly disappears. Insist on a Manual J, pick an efficiency tier your climate can justify, and pocket every incentive that still applies after the federal credits lapsed.
