Knowing what fixing a furnace includes can help you save time and money. 

This guide will tell you how much it costs to fix a furnace and what parts are most likely to break. It will also help you understand the procedure, the expenses and how to keep your home warm and safe all-year long.

Understanding Furnace Repair Costs

Many individuals want to know how much it costs to fix a furnace and why the pricing is different. The price will depend on the type of furnace you have and how long it takes to fix it.

Some parts like the flame sensor or ignitor are easier and less expensive to fix. Repairing central furnaces may cost more than repairs on small home units since central systems have more parts and wires.

Factors That Impact the Cost of Furnace Repairs

The cost of fixing a furnace varies from one home to the next because each furnace has various parts and problems. Some repairs are easy and quick while others take longer. It can help you understand why the cost can be low or high at different times.

What Makes Furnace Repair More Expensive

  • Type of Furnace: Gas furnaces may need to have their gas valve or pilot light fixed while electric furnaces may need the control board fixed. The cost and necessity for repairs are different for each system.
  • Age of the Furnace: It’s usually cheaper to fix newer furnaces because it’s easier to find parts.
  • The Condition of the System: If the furnace hasn’t been cleaned or serviced it may have more problems throughout the repair process. 
  • Emergency Repairs: If your furnace breaks at night or when it’s very cold outside, no matter the time of the day, you need it fixed quickly.

Quick DIY Troubleshooting Tips for Your Furnace

You may do a few simple things on your own before you contact for help with your central furnace. Make sure the thermostat is set to heat and that the temperature is higher than the temperature in the room. 

If your air filter is unclean, it could block airflow and stop the furnace from working. Look at the furnace’s power switch and the breaker panel to see if a breaker has tripped. 

You may push a reset button on some furnaces to start them up again. Check the pilot light on your ancient gas furnace to see if it has gone out.

Newer furnaces include blinking lights that show simple problem codes. You can look in the manual for help with these codes. If none of these methods work you should stop trying to fix the problem and don’t make the furnace run.

Common Furnace Part Failures Every Homeowner Should Know

A lot of people want to discover why their furnace stops operating and what parts break the most. The parts that get the most calls for furnace repairs are listed below.

  • Ignitor for the furnace: If it doesn’t work the furnace won’t turn on. 
  • Flame Sensor: The furnace turns off early if it breaks. Fixing the furnace flame sensor often cures this problem quickly.
  • Motor for the Blower: If it doesn’t work the air doesn’t move even if the furnace is hot. Adding oil or replacing parts can be done to fix it.
  • Pressure Switch: The system won’t start if it becomes stuck or breaks. 
  • Gas Valve: It won’t work if it breaks. A qualified technician should always fix the furnace gas valve.
  • Control Board: Sometimes the only way to fix the problem is to repair or replace the furnace control board.
  • Heat Exchanger: Cracks or other damage can let gas leak out which is harmful.
