What Is the Average Cost to Install Central Air in a Home?

There isn’t a single “average cost” for central air installs. Price depends on system size, duct condition, electrical needs, and refrigerant requirements confirmed during an on‑site assessment. First Call Jewel specializes in retrofit installations for existing homes and businesses in Idaho Falls and nearby cities. Typical installs include: condenser, line‑set, pad, disconnect and wiring, thermostat, evaporator coil, furnace blower, condensate drain, filter, and ducts sized to the unit. Refrigerants require licensed handling, and 2025 R454B models include built‑in leak detection. Financing up to 60 months at 0% OAC is available.
