How much should this gap actually matter?
A 2% 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 type: Houston vs Killeen
Each central AC installation option, priced separately for both metros — the same local labor, climate and permit adjustments applied per city, so you can compare like for like.
| Type | Houston | Killeen |
|---|---|---|
| 2–3 ton (small home) | $5,400–$8,500 | $5,300–$8,350 |
| 3.5–4 ton (mid home) | $7,500–$11,600 | $7,350–$11,450 |

Central AC installation by home size: Houston vs Killeen
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 | Killeen |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,900–$8,500 | $4,800–$8,350 |
| 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 | $5,800–$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–$16,550 |

What hvac pros earn in each metro
About 60% of a central AC installation bill goes to labor, so wage differences between these two metros matter more than almost anything else. These are real, government-sourced (BLS OEWS) installer wages, not estimates.

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 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 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.
Match the efficiency tier to your climate, insist on a real load calculation, and stack every rebate you qualify for. The expensive mistakes are wrong sizing and a rushed install — not picking the "wrong" brand.
