Frequently Asked Questions about Furnace Repair

What causes a furnace to stop working?

There are several reasons why your furnace might stop working, ranging from simple issues to more complex problems. Here are some possible culprits:

• 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 cause many problems. Try replacing the filter.
• Ignition problems: The igniter or pilot light (in older furnaces) is responsible for lighting the burners. 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 heat exchanger, flame sensor, control board, or limit switch, can also cause furnace malfunctions..

It is typically best to avoid trying to fix the furnace on your own unless you're a qualified HVAC professional.

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: Regular maintenance significantly impacts the lifespan of your furnace. A preventative maintenance plan are essential.
• Usage: Frequent or continuous use puts more strain on your system.
• Quality: Higher-quality furnaces from reputable brands are typically more durable.
• Proper Installation: Correct installation is key to longevity.

If your furnace is over 15 years old and starting to experience frequent problems, it may be time to consider replacing it.

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

If your furnace is exhibiting any of the following signs, it may be time for a replacement:

• Age: If your furnace is 15-20 years or older, it is likely less efficient and more expensive to operate.
• Frequent Repairs: If your furnace requires constant attention, 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: Listen for odd noises coming from the unit.
• Yellow Flame: A healthy furnace flame should be blue. A yellow flame suggests 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?

Before calling for repairs, consider resetting your furnace. 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 fully power down.
4. Turn the power back on: Flip the circuit breaker back to the 'on' position.
5. Turn on the furnace: Turn the thermostat back on and set it to your desired temperature.

If the problem persists or if you encounter error codes, don't attempt to diagnose or repair the issue yourself.
