How to get an accurate quote

  1. Get several quotes and compare, not just price.
  2. Be specific about size, materials and any existing issues.
  3. Ask whether the quote includes labor, materials, permits and cleanup.
  4. Confirm the contractor is licensed and insured before you hire.

Cost by type

Furnace cost depends on fuel type and efficiency. Here's the typical installed range:

Furnace typeTypical cost
Gas (80% AFUE)$3,500 – $5,000
Gas (90%+ AFUE)$4,500 – $6,500
Electric$3,000 – $5,000
Oil$4,000 – $6,500
Efficiency pays back

A high-efficiency furnace costs more up front but can lower heating bills substantially, especially in cold climates.

Example

Replacing a gas furnace

Replacing a 20-year-old gas furnace with a 96% AFUE unit in a 2,000 sq ft home typically runs around $5,500 installed, including the permit. Adding a smart thermostat adds ~$200.

How to save

  • Check utility and manufacturer rebates for high-efficiency models.
  • Replace only when needed — don't oversize.
  • Bundle with the AC installation if you're replacing both.
  • Get multiple itemized quotes.
