How much should this gap actually matter?
A 1% 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: Cape Girardeau vs Columbia
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 | Cape Girardeau | Columbia |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,300–$7,550 | $4,400–$7,600 |
| 1,500 sq ft (≈2.5 tons) | $4,800–$8,900 | $4,850–$9,000 |
| 2,000 sq ft (≈3 tons) | $5,250–$10,300 | $5,300–$10,400 |
| 2,500 sq ft (≈4 tons) | $6,600–$12,100 | $6,700–$12,250 |
| 3,000+ sq ft (≈5 tons) | $8,000–$14,850 | $8,100–$15,050 |
These are 2026 planning figures for central AC installation, localized to each city — not formal quotes.
Cheapest time for central AC installation in either city
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 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 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 longevity case
Brand is a footnote; sizing and install quality write the story. A right-sized mid-tier system that's properly commissioned and serviced once a year will outlive an oversized premium unit that short-cycles itself to an early grave. Put the money into the crew and the setup rather than the nameplate.
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.
