Frequently Asked Questions about Furnace Repair

What causes a furnace to stop working?

There are several reasons why your furnace might stop working, 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. A tripped breaker is a common and easily resolved problem.
• 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 dirty 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 inducer motor, capacitor, or pressure switch, might be responsible.

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. However, this can vary depending on several factors: depends on several factors, including::

• Maintenance: Preventative maintenance significantly impacts the lifespan of your furnace. Annual checkups and timely repairs are essential.
• Usage: Frequent or continuous use puts more strain on your system.
• Quality: Well-built models are typically more durable.
• Proper Installation: Correct installation is crucial for optimal performance and 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?

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 prone to breakdowns.
• Frequent Repairs: If your furnace requires frequent and costly repairs, it may be more economical to replace it than to continue fixing 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 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 a problem with the burners or venting. If you see a yellow flame, contact a qualified HVAC technician right away.
• Dry Air: While not a direct indicator of malfunction, older furnaces can make your indoor air very dry.

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 reset.
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 after the reset, don't attempt to diagnose or repair the issue yourself.
