Estimate the cost of a brand-new furnace + AC combo, full heat pump system, or ductless multi-zone install — in about 15 seconds.
A new furnace + AC combo, full heat pump system, or ductless multi-zone install typically runs $8,000 to $20,000+ depending on home size, efficiency tier, and whether new ductwork is needed. Use the calculator above for an estimate tailored to your home.
Heat pumps typically cost somewhat more upfront than a comparable furnace + AC combo, but they replace two systems with one and can lower operating costs. Compare with our Heat Pump Savings calculator.
If your home already has ductwork in good condition, it can usually be reused. Homes without existing ducts, or with severely damaged ducts, will need new duct installation, which adds significantly to project cost.
Most furnace + AC or heat pump installs with existing ductwork take one to two days. Projects requiring new ductwork can take three to five days.
This calculator provides a rough estimate based on common industry pricing rules of thumb. Actual costs vary by contractor, brand, permit fees, and site conditions. Always get a written quote from a licensed local HVAC contractor before making a purchase decision.
