Why Does My HVAC System Smell Like It’s Burning?

It can be alarming to discover a burning smell in your home, and you may immediately search the home to locate the source. Worse, you may discover the burning smell originates from your heating or cooling system. If this is the case, you will need a licensed HVAC technician to help you determine the cause and remedy the situation for you. 

If You Recently Turned On Your System

It is rather common to notice a burning smell when you initially turn on the heater or the cooling system for the first time in months. The system may get dusty and dirty while sitting unused, and the initial burning smell you notice may be the dust and other debris burning away. Generally, when this is the cause of the burning smell you notice, the smell will dissipate within a few minutes of turning on the system. 

If the System Has Been Running

Another cause of a burning smell relates to the blower motor. When your blower motor is going out, or has completely gone out, you may notice a burnt smell in the air that blows through the vents. This is a repair issue that a technician will need to resolve for you, and it typically requires the replacement of the blower. 

An HVAC Fire

In rare cases, the HVAC unit itself may be on fire. This is a true emergency situation that will require you to call the fire department for assistance. You will know if this is the case if you inspect the system and see flames.
