We localize each central AC installation type separately for both metros, applying the same labor, climate and permit adjustments each time, so you're comparing like for like.

Central AC installation by home size: Lewisville 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 | Lewisville | San Antonio |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,400–$7,700 | $4,800–$8,400 |
| 1,500 sq ft (≈2.5 tons) | $4,900–$9,100 | $5,300–$9,900 |
| 2,000 sq ft (≈3 tons) | $5,350–$10,500 | $5,850–$11,450 |
| 2,500 sq ft (≈4 tons) | $6,750–$12,350 | $7,350–$13,500 |
| 3,000+ sq ft (≈5 tons) | $8,150–$15,200 | $8,900–$16,600 |

What hvac pros earn in each metro
Since labor accounts for around 60% of what a central AC installation job costs, it's the biggest lever behind any price gap between cities. What you're seeing below is actual BLS metro wage data for skilled installers — not a guess.

Cheapest time for central AC installation in either city
HVAC demand collapses in the mild shoulder seasons, so installers discount to keep crews busy. The most expensive time to buy is during a heat wave or cold snap, when a dead system forces a full-price emergency replacement.
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
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 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.
If there's one takeaway, it's this: sizing and install quality decide whether an HVAC system performs, not the badge on the box. Get the load calculation right, match efficiency to climate, and take the rebates on offer.
