Heating and air conditioning systems provide comfort to any space. That space can become uncomfortable when strange smells begin coming through the vents. Keep reading to learn some of the common culprits that can cause an HVAC unit to turn stinky.
If there is a musty smell coming from your HVAC vents, then chances are they just need a good cleaning. Mildew is the most common cause of odor from air vents. Water that doesn’t completely drain away or evaporate can be a perfect breeding ground for mildew and mold. The good thing is that a thorough cleaning should solve the problem. Once the mildew is gone, your air should smell fresh again.
A smell of garbage or rotting may be coming from your vents if there is something stuck in the ductwork. Unfortunately, it is not uncommon for small critters to find their way into the vents. If the odor you are encountering is rather rancid, then these creatures are more than likely the problem. This will not cause trouble for your HVAC system, but you will want to get rid of the source of the smell as soon as possible.
If the smells coming from your vents do not fall into the categories above, the stench may indicate a bigger issue. Here are some of the most common odors and what might be causing them:
Often a burning or gas smell may come through the vents when your heater first kicks on for the season. When the unit turns on after sitting unused for months, the dust that has collected on the coils will begin to burn off. This smell should go away after 20 to 30 minutes. If it doesn’t, then it may be time to call in the professionals. An HVAC service provider will be able to help you get to the source of the problem.
