How much does furnace replacement typically cost for homeowners?

Furnace replacement pricing depends on your home and system. We provide flat-rate, up-front pricing after an on-site diagnostic, and the $179 diagnostic is waived with any approved repair or replacement. You’ll get clear options to Repair, Rebuild/Refresh, or Replace, including high-efficiency upgrades for Nassau County homes.

What affects price:

  • Furnace size and efficiency rating
  • Fuel type (gas, oil, or electric)
  • Ductwork or venting changes
  • Thermostat/controls and safety upgrades
