Is the price difference a dealbreaker?
1% is within noise for central AC installation — contractor selection and timing move the price more than which of these two metros you're in.

Central AC installation by home size: Houston 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 | Houston | San Antonio |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,900–$8,500 | $4,800–$8,400 |
| 1,500 sq ft (≈2.5 tons) | $5,400–$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) | $7,500–$13,700 | $7,350–$13,500 |
| 3,000+ sq ft (≈5 tons) | $9,050–$16,800 | $8,900–$16,600 |

What hvac pros earn in each metro

Cheapest time for central AC installation in either city
A furnace or AC that dies mid-heat-wave gets replaced at whatever the on-call crew charges. One that gets swapped in April or October gets a competitive, unhurried quote instead.
How much should you really budget for HVAC in 2026?
Get the sizing wrong or the efficiency tier mismatched to your climate, and the price drifts fast in either direction. Below, a look at how those choices — plus brand markup — shape the real number.
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
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.
Skip the brand debate. A correctly sized system, an efficiency tier that fits your climate, and a properly commissioned install will save you more than any label ever could.

Should I choose where to live based on central AC installation cost?
Rarely. The $100 difference is real but one-time, and you can often close most of it in Houston 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.
