Central AC Replacement vs Heat Pump Installation
Central AC + gas furnace runs $10k–$23k and is the LA default; a heat pump (all-electric) is $14k–$28k after panel upgrades but qualifies for federal IRA rebates of $2k–$8k.
Mini-Split Installation vs Central AC Replacement
Mini-splits skip ductwork at $4.5k–$10k per zone and fit older LA homes; central AC requires existing or new ductwork but is more efficient on larger floor plans.
