Are strange smells coming from your air conditioner vents? They can be overbearing at times and may leave you wondering if it’s time to call an HVAC contractor. While it’s not uncommon for smells to circulate now and then, it’s important to address them. In some cases, they can mean something is seriously wrong, potentially even putting your safety at risk. Below, you’ll find a few recognizable smells and what they mean.

Common HVAC Smells

1. Rotten Eggs

The smell of rotten eggs is hard to miss; when you notice it in your home, it usually means there’s a gas leak. It may be coming from your furnace, gas stove, or water heater. Regardless, you need to leave immediately and call the gas company. They can disconnect the service, and an HVAC contractor and other professionals can investigate to see what’s causing the issue.

2. Musty Smells

Musty smells are another common occurrence, and while they don’t necessarily mean anything is wrong with your AC unit, it does mean that you’re dealing with a potential mold issue. Mold often grows in air ducts when there’s excess moisture coming from your system. Over time, it can impact air quality and cause respiratory complications. A comprehensive air duct cleaning is usually enough to resolve the issue.

3. Electrical Smells

Often, sharp, mechanical smells are due to overheating. However, it could be as simple as an air filter issue. You don’t want to overwork your system, so turn it off before doing anything. If you don’t have experience with electrical wiring or appliances, call an HVAC contractor so you don’t put yourself at risk of shock.
