Central AC installation by home size: Mission 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 | Mission | 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
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?
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
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
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 longevity case
The single biggest cost driver isn't the brand — it's correct sizing and install quality. A properly sized, well-commissioned mid-tier system with annual maintenance outlasts an oversized premium unit that short-cycles. Spend on the install, not the badge.
The costly errors in an HVAC job are a bad load calculation and a sloppy install — not the logo you chose. Size it with a real Manual J, let your climate set the efficiency tier, and claim whatever rebates you still qualify for.

Yes — and the wage data shows it. A skilled installer earns about $24.2/hr in the McAllen-Edinburg-Mission area versus $28.4/hr around San Antonio-New Braunfels (BLS metro wage data). Since labor is roughly 60% of a central AC installation job, that wage gap is the biggest reason the installed prices differ.

Timing doesn't change by city here — Spring and fall (Mar–May, Sep–Oct) is the cheapest window in both Mission and San Antonio, saving roughly 5–15%. Avoid peak summer and mid-winter in either location, when emergency replacements push prices up.
Should I choose where to live based on central AC installation cost?
Not really — the $800 gap is one-time, and smart timing and tighter quotes in San Antonio can shrink it. Factors that compound over time, like energy prices and home condition, deserve more weight than a single upfront difference.
