Frequently Asked Questions about Furnace Repair

What causes a furnace to stop working?

There are many potential causes of furnace failure, from minor issues to major breakdowns. Here are some possible culprits:

• Lack of power: Check the circuit breaker to ensure the furnace is receiving power. Make sure the power switch near the furnace is also on.
• Thermostat problems: Check that the thermostat is set correctly to 'heat' and at a temperature higher than the current room temperature. Replace batteries if the display is blank or not working. Try resetting the thermostat or replacing the batteries. If that doesn't solve the problem, the thermostat may need to be replaced.
• Clogged air filter: A clogged air filter can restrict airflow and prevent the furnace from working efficiently.. Try replacing the filter.
• Ignition problems: Issues with the igniter or pilot light can prevent the furnace from starting. A faulty igniter or pilot light may need to be cleaned or replaced..
• Blower motor issues: The blower motor is crucial to distributing warm air throughout your home. If the blower motor is broken, the furnace may not produce enough heat.
• Gas supply problems (for gas furnaces): Gas furnaces require both gas and electricity to function properly. Check that there are no gas leaks.
• Other component failures: Other components, such as the inducer motor, capacitor, or pressure switch, might be responsible.
