When the HVAC system in your Columbus, Georgia, home is working properly, you probably pay no attention to it. But you’ll definitely notice it if there are strange odors coming from the system. Let’s discuss four common HVAC smells and what they mean.

Electrical Smell

When you turn on your heating system the first few times after the weather has started cooling, there may be a slight electrical smell that goes away within a few minutes. However, if your HVAC system continues to smell hot, it could be overheating. In this case, turn it off immediately.

The next step is to check the air filter. If it’s dirty, it will restrict airflow and cause the system to overheat. Change the filter if necessary. If it is not the filter, turn off the power to the unit and call a professional HVAC technician to check it out.

Rotten Eggs

A smell of rotten eggs most likely indicates a natural gas leak. This is unsafe and unhealthy. Open all your windows, leave the house, and call the gas company immediately.

Burning Smell

If your heating system was turned off during the summer months, dust can settle in the HVAC system. When the furnace is turned on, the dust burns off, causing a burning smell. However, if the smell does not dissipate soon, it could be coming from a malfunctioning part of your system, in which case you should call an HVAC technician immediately.

Musty Smell

A musty smell coming from your HVAC unit is a cause for concern. It could be a sign of biological growth resulting from excess moisture in your ductwork. Biological growth can affect the health of your family members.

Never assume that a strange smell coming from your HVAC system is harmless because some smells can indicate serious issues. Call a professional HVAC technician at Climate Control Heating & Air Conditioning at 706-405-4796 to diagnose it.
