Is the price difference a dealbreaker?
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 home size: Baton Rouge vs New Orleans
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.

|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,850–$8,450 | $4,900–$8,550 |
| 1,500 sq ft (≈2.5 tons) | $5,350–$9,950 | $5,400–$10,100 |
| 2,000 sq ft (≈3 tons) | $5,850–$11,500 | $5,950–$11,650 |
| 2,500 sq ft (≈4 tons) | $7,400–$13,550 | $7,500–$13,750 |
| 3,000+ sq ft (≈5 tons) | $8,950–$16,650 | $9,050–$16,850 |

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?
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 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 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.
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.
