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. Some of the most common causes include::

• 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 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 inducer motor, capacitor, or pressure switch, might be responsible.

What is the average lifespan of a furnace?

The average lifespan of a furnace is typically 15 to 20 years. However, this can vary depending on several factors: is influenced by:

• Maintenance: Regular maintenance significantly impacts the life 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 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?

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 more economical to replace it than to keep repairing 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 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 suggests the presence of carbon monoxide, which is a serious safety hazard. A yellow flame requires immediate attention.
• 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 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 continues after the reset, it's best to call a qualified HVAC technician for diagnosis and repair..
