Furnace replacement in South Fayette typically runs $3904 to $9760 for a natural gas system, including the unit, venting, thermostat and labor. High-efficiency (96%+ AFUE) models cost more upfront but save significantly on Pennsylvania gas bills — often paying back in 3-5 years. The final price depends on home size, BTU requirements, and whether venting modifications are needed. A licensed South Fayette HVAC contractor will perform a load calculation to properly size your system.

General rule: if your AC is over 12 years old and repair cost exceeds $1,000 (e.g., compressor failure), replacement is usually the better investment at $4684-$11712. If the system is under 10 years old and the repair is under $500-600, repair makes sense. The '5,000 rule': multiply the system's age by the repair cost — if over $5,000, replace. Also consider: R-22 refrigerant (being phased out, very expensive to recharge), rising energy bills, and uneven cooling. A licensed South Fayette HVAC tech can advise after diagnosis.

After installation, the system is pressure-tested, charged with refrigerant, and tested for proper operation before the crew leaves.
