National Baseline & Scope Drivers
Replacing a residential furnace, air conditioner or heat pump, including installation and startup. National planning range for this job sits between $4,500 and $20,000.
Key Price Drivers for HVAC System Replacement
- What you are replacing: A furnace alone, a condenser alone, or a full system with coil and air handler are three very different prices. Matched full-system replacement costs more but performs to its rating.
- Capacity and efficiency: Each additional ton adds cost, and high-SEER2 variable-capacity equipment can double the equipment line versus a base single-stage unit.
- Ductwork condition: Undersized or leaking ductwork must be corrected for the new system to perform. Duct modification frequently adds $1,500 to $5,000 and is the most commonly omitted item in a low bid.
- Electrical and gas work: Heat pump conversions often require a new circuit, a disconnect, and sometimes a panel upgrade. High-efficiency furnaces require new PVC venting and a condensate drain.
- Refrigerant transition: Equipment has moved to A2L refrigerants such as R-454B. Line set compatibility and flush requirements can add cost on a changeout.
