What Affects AC Installation Costs in Jefferson Hills
Prices vary based on system size and efficiency, ductwork condition, and permit fees. Older homes (median built 1981) may need duct repairs or new ductwork, adding $1,900–$4,700. Choosing a heat pump instead of a central AC can cost $4,700–$11,200+, but qualifies for a larger 25C credit (up to $2,000).

SEER2 ratings above the 13.4 minimum increase upfront cost but lower long-term energy bills.
