Common Furnace Issues We Can Solve!
The furnace in your home needs to function properly in order for those that reside in your home to live comfortably. That’s why when you notice any issue with your heating system, it is important to have it repaired by a professional.
The experts at Smith Heating & Air in Knoxville, TN can help with all of your common heating repair needs.
Ignition Problems
Gas furnaces rely on an ignition system to light the burners. Ignition problems can result from faulty igniters, pilot lights, or electronic ignition components.
Thermostat Issues
Sometimes, heating problems stem from a malfunctioning thermostat. It may not be accurately reading the temperature, leading to inconsistent heating or cooling.
Blower Motor Problems
Sometimes, heating problems stem from a malfunctioning thermostat. It may not be accurately reading the temperature, leading to inconsistent heating or cooling.
Clogged Condensate Drain
High-efficiency furnaces have condensate drains that can become clogged with debris. This can cause water leaks and affect the furnace’s operation.
Faulty Limit Switch
The limit switch is a safety feature that shuts off the furnace if it gets too hot. A malfunctioning limit switch can cause the furnace to overheat and shut down prematurely.
Pilot Light or Ignition Control Problems
Older furnaces with pilot lights may experience issues with the pilot light going out or the ignition control system failing.
Dirty Burners
Over time, the burners in a gas furnace can become dirty or corroded, affecting their ability to produce a consistent flame.
Flame Sensor Issues
The flame sensor ensures that the burners are lit. If it’s dirty or malfunctioning, it can cause the furnace to cycle on and off or not ignite at all.
Heat Exchanger Problems
Cracks or leaks in the heat exchanger can be a serious issue, as they can release carbon monoxide into your home. This is a critical safety concern and should be addressed immediately.
Electrical Problems
Various electrical components, such as wiring and control boards, can develop issues over time. These may require professional diagnosis and repair.

It’s important to address furnace issues promptly to prevent further damage, ensure your comfort, and maintain the safety of your home. Regular maintenance can also help prevent many of these issues and extend the lifespan of your heating system. If you suspect a problem with your furnace, it’s advisable to contact a qualified HVAC technician at Smith Heating & Air to diagnose and repair the issue.
