Central AC installation by home size: Columbus vs Marietta
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 | Columbus | Marietta |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $5,250–$9,150 | $4,900–$8,500 |
| 1,500 sq ft (≈2.5 tons) | $5,800–$10,850 | $5,400–$10,100 |
| 2,000 sq ft (≈3 tons) | $6,350–$12,500 | $5,950–$11,650 |
| 2,500 sq ft (≈4 tons) | $8,050–$14,750 | $7,500–$13,700 |
| 3,000+ sq ft (≈5 tons) | $9,700–$18,100 | $9,050–$16,800 |

Cheapest time for central AC installation in either city
Demand for HVAC work falls off a cliff in the shoulder months, and contractors discount to keep their crews booked. Wait for a 100-degree day or a hard freeze, though, and you're paying emergency rates for a system that just quit.
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
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 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 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.
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.
