How much should this gap actually matter?
That 1% gap is small — for central AC installation it's usually less than the spread between two local contractors' quotes, so the metro matters far less than who you hire and when you buy.

Central AC installation by home size: Corpus Christi vs San Antonio
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 | Corpus Christi | San Antonio |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,850–$8,500 | $4,800–$8,400 |
| 1,500 sq ft (≈2.5 tons) | $5,350–$10,050 | $5,300–$9,900 |
| 2,000 sq ft (≈3 tons) | $5,900–$11,600 | $5,850–$11,450 |
| 2,500 sq ft (≈4 tons) | $7,450–$13,650 | $7,350–$13,500 |
| 3,000+ sq ft (≈5 tons) | $9,000–$16,750 | $8,900–$16,600 |

Cheapest time for central AC installation in either city
Why spring and fall are cheaper: contractors have open calendar space and compete harder for the work. Why summer and deep winter are expensive: a broken system in extreme weather isn't optional, so you lose your negotiating leverage.
How much should you really budget for HVAC in 2026?
Three factors move an HVAC quote more than anything else: how well it's sized, which efficiency tier you pick, and the brand markup. Our editors break down how they weigh each one.
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.
