The HVAC system in your James Island, South Carolina, home is one of the most highly utilized systems, providing heated and cooled air throughout the changing seasons. When something is awry in the system, you may notice some odd odors coming through your vents. What you smell can indicate what’s wrong with your system, so make sure to get these issues checked out.

Rotten Eggs

A rotten egg smell is a familiar odor that is always concerning. Natural gas has the rotten egg smell added to it so you can detect a potential leak, so if you catch a whiff, make sure to turn off the system and contact your local gas provider as soon as possible. A natural gas leak can lead to an explosion if left unresolved, so this is a problem that should be addressed right away.

Electrical Odors

When a system is brand new or running for the first time after a period of non-use, it is normal to smell a little dust burning off. However, when you smell a burning odor, it likely means that something is overheating within the unit. The first step is to check the air filter, as a dirty, clogged filter can restrict airflow and result in overheating. If that’s not the problem, turn off your system and contact an HVAC professional right away to take a closer look.

Foul Odors

A foul odor may mean that some type of animal has found its way into your ductwork and died. Although this is an unpleasant situation, an HVAC technician can typically take care of the issue and clean out the ducts to prevent further smells.

Musty Smells

Catching a whiff of a musty odor might mean your system has moisture that has resulted in biological growth. When moisture can’t drain out of the unit properly, it can move into the ducts, causing growth that spreads its spores through the air.
