Is the price difference a dealbreaker?
4% is within noise for central AC installation — contractor selection and timing move the price more than which of these two metros you're in.
Central AC installation by type: Florence vs Montgomery

Central AC installation by home size: Florence vs Montgomery
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 | Florence | Montgomery |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,550–$8,000 | $4,750–$8,300 |
| 1,500 sq ft (≈2.5 tons) | $5,050–$9,450 | $5,300–$9,850 |
| 2,000 sq ft (≈3 tons) | $5,550–$10,900 | $5,800–$11,350 |
| 2,500 sq ft (≈4 tons) | $7,000–$12,850 | $7,300–$13,400 |
| 3,000+ sq ft (≈5 tons) | $8,450–$15,800 | $8,850–$16,450 |

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?
What you pay for HVAC hinges less on the badge than on how the quote is built — the load calculation behind it, the efficiency tier, and the markup. Our take on where each one lands.
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.
The budget-first case
In a temperate region the smart move is to size the job correctly with a Manual J and take the base efficiency tier. A system that spends most days coasting can't recover the cost of a high-SEER2 compressor, because the savings only show up under heavy load you don't put on it. Match the equipment to how little you actually run it, not to the brochure's top number.
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.
