AC installation cost by system.
Installed pricing for Farmington, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
Farmington, Michigan homeowners considering AC installation face costs shaped by the city's older housing stock and cold climate. With a median home built in 1967, many homes need ductwork modifications or new systems sized for sub-zero winters. Typical like-for-like central AC installation runs $3,700–$7,400, while a full system with new ducts can cost $5,600–$12,100+. Ductless mini-splits and heat pumps offer alternatives, with heat pumps eligible for federal tax credits up to $2,000. Michigan requires a mechanical permit and inspection for all installations, and equipment must meet a minimum SEER2 of 13.4 for the North region. Choosing the right system—often a dual-fuel setup—balances efficiency and heating performance.
