Frequently Asked Questions about Furnace Repair

What is a heat exchanger in a furnace?

The heat exchanger plays a key role in a furnace. It warms the air blown into your home. The heat exchanger also acts as a barrier between the combustion gases and the circulating air, preventing harmful gases, such as carbon monoxide, from leaking into your living space.. Cracks in the heat exchanger can be very dangerous, causing carbon monoxide to enter your house. Annual maintenance by a professional is highly recommended.

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. A malfunctioning thermostat requires replacement.
• 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 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 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 .

How do I know when it's time to replace my furnace?

Here are signs that your furnace is nearing the end of its lifespan and may need replacing::

• Age: If your furnace is 15-20 years old or older, it's likely time to consider a replacement.
• Frequent Repairs: Multiple repairs, especially costly ones, suggest it's more economical to invest in a new, more reliable unit..
• High Energy Bills: A noticeable increase in your heating bills might be caused by an inefficient furnace.
• Uneven Temperatures: If you have cold spots, it could be a sign of problems with your furnace or ductwork.
• Strange Noises: Unusual or loud sounds suggest mechanical issues.
• Yellow or Flickering Burner Flame: A healthy furnace flame should be blue. A yellow or flickering flame can indicate a variety of issues. This should be addressed right away.
• Dry or Dusty Air: An old furnace may cause dry, dusty indoor air. Upgrading your system can improve comfort and IAQ.

If you're experiencing any of these signs, it's advisable to consult with an HVAC professional for a furnace inspection and assessment.

What are some tips for maintaining my furnace?

Regular furnace maintenance is key to preventing costly repairs and ensuring its efficient operation. Here are some tips:

• Change the air filter regularly (every 1-3 months): A dirty filter restricts airflow, reducing efficiency and potentially damaging the system.
• Schedule an annual furnace tune-up: A professional technician can inspect, clean, and test all components, ensuring optimal performance and safety.
• Keep the area around the furnace clear: Remove any flammable materials or obstructions that could block airflow.
• Check and clean the furnace vents: Make sure vents are not blocked by furniture or other items.
• Install a programmable thermostat: This helps optimize heating schedules and save energy.
• Seal air leaks around windows and doors: This prevents heat loss and improves efficiency.

Proactive maintenance can prevent unexpected breakdowns and reduce energy bills.
