Central AC installation by home size: Alexandria vs Baton Rouge
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 | Alexandria | Baton Rouge |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,650–$8,100 | $4,850–$8,450 |
| 1,500 sq ft (≈2.5 tons) | $5,150–$9,600 | $5,350–$9,950 |
| 2,000 sq ft (≈3 tons) | $5,650–$11,100 | $5,850–$11,500 |
| 2,500 sq ft (≈4 tons) | $7,100–$13,050 | $7,400–$13,550 |
| 3,000+ sq ft (≈5 tons) | $8,600–$16,050 | $8,950–$16,650 |
Treat these as 2026 localized estimates for central AC installation, not quotes from a contractor.

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?
Sizing, efficiency tier and brand pull a quote in different directions. Here's how our editors weigh the trade-offs that decide what you actually pay.
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
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 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.
Climate decides the efficiency tier; a proper load calculation decides everything else. Nail both, stack the rebates you can, and you've sidestepped the two mistakes — wrong size, rushed install — that actually inflate the lifetime cost.
