What’s Causing That Yucky Smell?

You may have noticed the air coming out of your vents smells a little off. While some odors can be temporary, others can linger and not only be troublesome, they can indicate a problem with your HVAC unit. Two common smells that you should always address are smoke and mold or mildew. The smell of smoke should be addressed immediately as it often indicates mechanical or electrical problems. When the motor or fan overheats, if the unit has not been properly cared for, it can smoke or even catch on fire. If you can smell something burning and you think the odor is flowing through your vents, shut off your HVAC system at the thermostat and check the unit outside. If you can see or smell any smoke coming from the condenser, keep the system turned off and call for help immediately. If you notice a damp and musty odor, chances are you smell mold or mildew.  Mold and mildew can creep into your coils and ductwork. If left untreated, it can spread throughout the home. Leaky ductwork, poor insulation, and blocked drainage tubes can all lead to this problem.  Correcting the root cause of the problem is the most important first step before beginning the cleanup phase. HVAC technicians have special cleaning methods they can use to clean ductwork and coils, which not only eliminates the odor, removes mildew spores circulating throughout the home, which are a major health hazard.
