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. 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. A malfunctioning thermostat requires replacement.
• Clogged air filter: A clogged air filter can restrict airflow and prevent the furnace from working efficiently.. Try replacing the filter.
• Ignition problems: The igniter or pilot light (in older furnaces) is responsible for lighting the burners. In newer furnaces, electronic ignition systems control this process and should be checked if there are problems.
• 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): Make sure the gas supply valve to the furnace is turned on.. 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 typically 15 to 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: Frequent or continuous use puts more strain on your system.
• Quality: Higher-quality furnaces from reputable brands tend to last longer.
• 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 more economical to replace it than to continue fixing it.
• Increasing Energy Bills: A significant increase in your heating bills could indicate that your furnace is losing efficiency.
• Inconsistent Heating: Uneven temperatures throughout your house could mean your furnace is no longer distributing heat evenly.
• 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.

It's important to address issues as soon as possible.

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 at least 30 seconds, though longer is sometimes recommended 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.
