Central AC installation by home size: El Centro vs San Diego
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 | El Centro | San Diego |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,750–$8,250 | $5,200–$9,100 |
| 1,500 sq ft (≈2.5 tons) | $5,250–$9,750 | $5,750–$10,750 |
| 2,000 sq ft (≈3 tons) | $5,750–$11,250 | $6,300–$12,400 |
| 2,500 sq ft (≈4 tons) | $7,250–$13,250 | $8,000–$14,600 |
| 3,000+ sq ft (≈5 tons) | $8,750–$16,250 | $9,650–$17,900 |

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 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
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
The most expensive variable on the quote isn't the logo — it's whether the system is sized right and installed well. Oversize a premium unit and it short-cycles, wears fast and underperforms; commission a correctly sized mid-tier one and keep up the annual service, and it simply lasts longer. Spend on the installation, not the badge.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.
