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. 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 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 qualified HVAC technician for diagnosis and repair .

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: Preventative maintenance significantly impacts the lifespan of your furnace. A preventative maintenance plan are essential.
• 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?

Indicators that your furnace may need replacement include:

• 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 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 isn't functioning as it should.
• 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 immediately.
• 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?

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