How much should this gap actually matter?
A 3% difference on central AC installation is minor — you'll typically see a wider spread just from getting multiple quotes in the same city, so don't let location drive the decision.

Central AC installation by home size: Oxnard 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 | Oxnard | San Diego |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,050–$8,800 | $5,200–$9,100 |
| 1,500 sq ft (≈2.5 tons) | $5,600–$10,400 | $5,750–$10,750 |
| 2,000 sq ft (≈3 tons) | $6,100–$12,000 | $6,300–$12,400 |
| 2,500 sq ft (≈4 tons) | $7,700–$14,100 | $8,000–$14,600 |
| 3,000+ sq ft (≈5 tons) | $9,300–$17,300 | $9,650–$17,900 |

Cheapest time for central AC installation in either city
Crews are busiest — and priciest — exactly when it's hottest or coldest, since that's when systems fail under load. Book in the mild months and you're negotiating from a position of choice, not a broken furnace.
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 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 budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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.
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.

Since labor is roughly 60% of a central AC installation job, that wage gap is the biggest reason the installed prices differ.

Should I choose where to live based on central AC installation cost?
Rarely. The $300 difference is real but one-time, and you can often close most of it in San Diego by buying in the off-season and getting tighter, apples-to-apples bids. Ongoing factors — energy prices, climate and home condition — matter more over the life of the system.
