AC installation cost by system.
Installed pricing for Morristown, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
Morristown homeowners typically pay $3,700–$7,500 for a like-for-like central AC replacement, $5,600–$12,200 for a new system with ductwork, and $4,700–$11,200 for a heat pump. Most homes were built in 1965, so ductwork may need upgrades. New Jersey requires a mechanical permit and inspection under the Uniform Construction Code (NJAC 5:23) even for a like-for-like swap. A permit typically costs $100–$300 and must be pulled before work begins. For efficiency, a gas furnace paired with a high-efficiency central AC (SEER2 ≥ 13.4) is a strong fit for Morristown's mixed-humid climate. The federal 25C tax credit offers up to $600 for qualifying AC units, reducing your out-of-pocket cost.

AC Installation in Morristown, explained.
What drives AC installation costs in Morristown?
System type is the main factor: a ductless mini-split runs $2,800–$7,500, while a heat pump costs $4,700–$11,200. Older homes (median built 1965) may need ductwork modifications or new ductwork, adding $1,500–$5,000. Labor rates reflect Morris County's median income of $113,926, and permit fees ($100–$300) are fixed. Choosing a higher SEER2 unit (e.g., 16+ SEER2) qualifies for the federal 25C tax credit, lowering net cost.

Permit and code compliance
New Jersey requires a mechanical permit and inspection for all AC replacements. Failing to pull a permit can result in fines or issues when selling the home.
Older ductwork condition
Many homes built in 1965 have undersized or leaky ducts. An installer may need to seal or replace ducts to meet modern airflow requirements.
Refrigerant transition
R-410A is being phased down after 2025. New installations must use R-454B or R-32, which may affect equipment availability and cost.
