What drives the cost
- System type: a full furnace-plus-AC split system, a heat pump, or a ductless mini-split each price very differently.
- Capacity (tonnage): larger homes need larger equipment; oversizing wastes money and undersizing shortens equipment life.
- Efficiency rating: higher SEER2/AFUE equipment costs more upfront but lowers utility bills.
- Ductwork condition: repairing, sealing, or replacing ducts can rival the equipment cost itself.
- Electrical and code upgrades: panel capacity, refrigerant line replacement, permits, and disposal of the old unit.
- Labor market and season: installers charge more during peak summer and winter demand.
Typical replacement process
- Load calculation (Manual J or similar) to size the new system.
- Written quote covering equipment, labor, permits, and haul-away.
- Removal of the old unit and refrigerant recovery.
- Installation of new equipment, line sets, and thermostat.
- Duct inspection, testing, and commissioning.
- Final inspection where the local jurisdiction requires a permit.
Choosing a contractor: checklist
- Licensed and insured for HVAC work in your state.
- Performs a real load calculation instead of matching the old unit's size.
- Itemized written quote — equipment model numbers included.
- Handles permits and refrigerant disposal themselves.
- Labor warranty in writing, separate from the manufacturer warranty.
- At least three comparable quotes before you commit.
