Your Furnace and Heating System Repair or Maintenance questions, answered

Answers to commonly asked questions from the experts on HomeGuide.

How much does furnace and heating system repair cost?

Furnace repair costs $100 to $480 on average, depending on the problem, furnace size, brand, and fuel type. Oil or gas furnace repairs cost $100 to $480, while electric furnace repairs cost $100 to $380.

An annual furnace maintenance plan costs $150 to $450 and includes an inspection, tune-up, cleaning, and minor repairs. Regular tune-ups to clean the air filters, burners, and pilot-light systems prevent major breakdowns and sudden furnace failures.

How much does furnace and heating system replacement cost?

Furnace replacement costs $2,000 to $5,400 on average, depending on the size, fuel type, brand, and efficiency. 

  • Natural gas and oil furnaces are typically more expensive than electric furnaces but cost less to run.
  • The Annual Fuel Utilization Efficiency (AFUE) rating measures the energy efficiency of the furnace. High-efficiency furnaces cost 30% to 100% more than standard-efficiency models but save $100 to $200 per year on energy bills.
  • Furnaces from popular brands like Carrier and Lennox typically cost more to install and repair than other brands.

Does homeowners insurance cover furnace repair?

Most homeowners insurance policies only cover furnace repairs if the breakdown was caused by a natural disaster, such as a fire or flood. Standard policies do not cover repairs for normal wear and tear. Consider adding equipment breakdown coverage to your policy to cover furnace and heating system repairs.

How long does it take to repair a furnace or heating system?

Furnace repair takes 1 to 2 hours on average, depending on the problem. Complete furnace or heating system replacement takes 5 to 18 hours, depending on the size, fuel type, and job complexity.

Do I tip the furnace repair guy?

Furnace repair technicians typically don't expect a tip, but they appreciate a $10 to $20 tip for outstanding service. Consider offering the technician a beverage, send positive feedback to their manager, and post a positive review online.

How do I choose the best furnace repair company near me?
