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. 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: 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 cause many problems. 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 circulates air through the furnace and ductwork. A faulty motor can prevent air from circulating properly..
• 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..

If you cannot identify or resolve the issue yourself, contact a furnace repair specialist .

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 depends on several factors, including::

• Maintenance: Regular maintenance can help extend the lifespan of your furnace. Annual checkups and timely repairs 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 are typically more durable.
• 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?

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 nearing the end of its lifespan and more prone to breakdowns.
• Frequent Repairs: If your furnace requires constant attention, it may be a better financial decision 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 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 the presence of carbon monoxide, which is a serious safety hazard. If you see a yellow flame, contact a qualified HVAC technician immediately.
• 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.
