Gas vs. Electric Furnace: Key Differences for Homeowners

Quick Answer
Gas furnaces usually cost more to install but less to operate where natural gas is available. Electric furnaces cost less to install but more to operate in cold climates. A heat pump is also worth comparing.
Key Takeaways
  • Fuel source availability often makes the call
  • Operating cost matters more than install cost over time
  • Heat pumps deserve consideration too
  • Local climate is a big factor

When each one wins

Gas wins on operating cost in cold climates where natural gas is available. Electric wins on install simplicity in mild climates or homes without gas. Heat pumps win on efficiency in many climates.

Questions to ask an HVAC contractor

  5. What warranty applies to equipment and labor, and how long does it last?
  6. How do you handle ductwork issues that come up during installation?
  7. Is there a discount, financing, or seasonal promotion that applies?
