Is the price difference a dealbreaker?
A 4% 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 type: Cary vs Greensboro

Central AC installation numbers here are 2026 planning ranges, adjusted per city — useful for budgeting, not a substitute for an actual quote.
Central AC installation by home size: Cary vs Greensboro
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 | Cary | Greensboro |
|---|---|---|
| 1,000 sq ft (≈2 tons) | $4,650–$8,150 | $4,500–$7,800 |
| 1,500 sq ft (≈2.5 tons) | $5,150–$9,600 | $4,950–$9,250 |
| 2,000 sq ft (≈3 tons) | $5,650–$11,100 | $5,450–$10,650 |
| 2,500 sq ft (≈4 tons) | $7,150–$13,050 | $6,850–$12,600 |
| 3,000+ sq ft (≈5 tons) | $8,600–$16,050 | $8,300–$15,450 |

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?
Ask five contractors for an HVAC quote and you'll get five different numbers — usually because they disagree on sizing, efficiency and equipment tier. Here's how our editors think through those trade-offs.
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 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 budget-first case
Run a Manual J load calculation, then buy the standard tier — 80% AFUE, 14.3 SEER2 — and stop there. Where summers are short and winters are gentle, the equipment idles most of the year, so premium efficiency never gets enough runtime to earn back its price. Paying for SEER2 you'll rarely tap is the classic way a mild-climate homeowner overspends.
The brand on the unit matters far less than getting the sizing and installation right. Insist on a Manual J calculation, match efficiency to your climate, and claim every rebate available.
