Central AC installation by home size: Chula Vista 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 | Chula Vista | San Diego |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,200–$9,100 | $5,200–$9,100 |
| 1,500 sq ft (≈2.5 tons) | $5,750–$10,750 | $5,750–$10,750 |
| 2,000 sq ft (≈3 tons) | $6,300–$12,400 | $6,300–$12,400 |
| 2,500 sq ft (≈4 tons) | $8,000–$14,600 | $8,000–$14,600 |
| 3,000+ sq ft (≈5 tons) | $9,650–$17,900 | $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 longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
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.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
