Is the gap worth worrying about?

Central AC installation by type: Carrollton vs San Antonio
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.
| Type | Carrollton | San Antonio |
|---|---|---|
| 2–3 ton (small home) | $5,450–$8,600 | $5,300–$8,400 |
| 3.5–4 ton (mid home) | $7,550–$11,750 | $7,350–$11,450 |
| 5 ton (large home) | $9,650–$17,000 | $9,400–$16,600 |

Central AC installation by home size: Carrollton 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 | Carrollton | San Antonio |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,950–$8,600 | $4,800–$8,400 |
| 1,500 sq ft (≈2.5 tons) | $5,450–$10,200 | $5,300–$9,900 |
| 2,000 sq ft (≈3 tons) | $6,000–$11,750 | $5,850–$11,450 |
| 2,500 sq ft (≈4 tons) | $7,550–$13,850 | $7,350–$13,500 |
| 3,000+ sq ft (≈5 tons) | $9,150–$17,000 | $8,900–$16,600 |

What hvac pros earn in each metro
Labor is about 60% of a central AC installation bill, so local wages drive most of the gap. These are real metro hourly wages for skilled installers (BLS OEWS), not estimates.

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?
An HVAC budget isn't one number — it's a set of trade-offs between sizing accuracy, efficiency tier and brand. Our editors walk through how each one moves the price.
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.
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.
The efficiency-first case
High runtime changes the math. In a demanding climate the extra efficiency of a heat pump or a top-tier SEER2/AFUE unit gets paid back month after month on the utility bill, and state and utility incentives can shave the upfront figure further now that the federal 25C/25D credits have expired. Price the lifetime bills, not just the tag, before you default down.
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.
