What Affects the Cost of a New Furnace?

  • Home Size and Layout
    Proper sizing ensures your system heats your home evenly without overworking.

  • Efficiency Rating (AFUE)
    Higher-efficiency furnaces (like 95% AFUE) cost more upfront but reduce long-term energy use.

  • Ductwork and Venting
    Modifications or upgrades to duct systems or venting can impact installation scope.

  • Installation Requirements
    Code compliance, electrical adjustments, and system configuration all factor into total cost.

  • 80% AFUE Furnaces
    Lower upfront cost and simpler installation, often used in existing system replacements.

  • 95%+ AFUE Furnaces
