Frequently Asked Questions about Furnace Repair

What causes a furnace to stop working?

There are many potential causes of furnace failure, ranging from simple issues to more complex problems. Some of the most common causes include::

• Lack of power: Check the circuit breaker to ensure the furnace is receiving power. A tripped breaker is a common and easily resolved problem.
• Thermostat problems: A faulty thermostat may not be signaling the furnace to turn on. 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 dirty 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 circulates air through the furnace and ductwork. A faulty motor can prevent air from circulating properly..
• 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 heat exchanger, flame sensor, control board, or limit switch, can also cause furnace malfunctions..

If you cannot identify or resolve the issue yourself, contact a qualified HVAC technician for diagnosis and repair .

What is the average lifespan of a furnace?

The average lifespan of a furnace is around 15-20 years. How long your particular furnace will last is influenced by:

• Maintenance: Preventative maintenance significantly impacts the lifespan of your furnace. A preventative maintenance plan can make your furnace more reliable.
• Usage: The more frequently you use your furnace, the shorter its lifespan will be.
• Quality: Higher-quality furnaces from reputable brands tend to last longer.
• Proper Installation: Correct installation is key to longevity.

An older furnace may require more repairs and cost more to operate.

What are the signs that my furnace needs to be replaced?

Indicators that your furnace may need replacement include:

• Age: If your furnace is 15-20 years or older, it is likely nearing the end of its lifespan and more expensive to operate.
• Frequent Repairs: If your furnace requires frequent and costly repairs, it may be a better financial decision to replace it than to keep repairing it.
• Increasing Energy Bills: A significant increase in your heating bills might suggest that your furnace is losing efficiency.
• Inconsistent Heating: Uneven temperatures throughout your home or business could mean your furnace isn't functioning as it should.
• Strange Noises: Unusual sounds coming from your furnace, such as banging, squealing, or rumbling, can signal mechanical problems.
• Yellow Flame: A healthy furnace flame should be blue. A yellow flame can indicate the presence of carbon monoxide, which is a serious safety hazard. If you see a yellow flame, contact a qualified HVAC technician right away.
• Dry Air: If you notice excessive dryness, a new furnace could provide increased comfort.

If you notice one or more of these warning signs, have a qualified HVAC technician inspect your furnace.

How do I reset my furnace?

If your furnace isn't working correctly, a simple reset can sometimes resolve the issue. Here's how to reset most furnaces:

1. Turn off the furnace: Set the thermostat to the 'off' position.
2. Turn off the power: Locate the circuit breaker for your furnace and switch it off.
3. Wait: Wait a few minutes for the system to reset.
4. Turn the power back on: Flip the circuit breaker back to the 'on' position.
