Central AC installation cost questions, answered
In 2026, expect $5,800–$8,400 for a 2-ton single-stage system, $8,500–$12,500 for a 3-ton two-stage system, and $12,500–$18,500 for a premium variable-speed install. Zoning, ductwork, and electrical upgrades can add $1,800–$4,200.
The lowest-cost path is a straight 2-ton single-stage replacement using existing ductwork and electrical — typically $5,800–$8,400. Skipping zoning, smart thermostats, and air-quality add-ons keeps the price down, but we still size it properly with a Manual-J calculation.
Higher labor rates, stricter local code requirements, and the cost of living in Nassau and Western Suffolk all push prices above national averages.
Yes — if you plan to stay in the home 5+ years. A 16–17 SEER2 two-stage system usually pays back in 4–6 years through lower summer electric bills. Variable-speed 18–22 SEER2 systems pay back faster if you use the AC heavily, and they qualify for bigger PSEG rebates.
PSEG Long Island runs a rebate of up to $1,000 on qualifying high-efficiency central AC. Heat pumps fall under its separate Clean Heat program. Eligibility and amounts are set by each program, so check PSEG Long Island's current terms before you buy.
Yes — flexible Synchrony financing. Promotional offers available, full terms in writing before you sign.
Most full-system replacements are completed in 1–2 days. Brand-new installations with new ductwork can take 3–4 days depending on complexity.
Sizing depends on square footage, insulation, ductwork, window orientation, and air leakage. We perform a Manual-J load calculation on every install — never the dangerous "one ton per 600 sq ft" guess.
A modern variable-speed system can cut cooling costs by 30–45% versus a 15-year-old unit, especially in humid Long Island summers.
Yes — old equipment removal, refrigerant recovery, and disposal are included on every install.
Up to 10-year parts warranty (with registration), labor coverage up to 10 years depending on the package, and our lifetime workmanship guarantee.
