Weird HVAC Smells and What They Mean

If you’ve been experiencing strange smells emitting from your home’s heating, ventilation, and air conditioning (HVAC) system. And are wondering what that could mean, don’t worry; you aren’t alone! A lot is happening behind the scenes at your home, which you probably don’t think about too often. However, it is crucial to understand what these smells mean, so you know when to call a professional for AC repairs in Roswell, GA

Here are some of the most ordinary smells your AC should not be making.

When Your HVAC Smells Like Dirty Socks

You might notice a musty odor from your HVAC system when it’s turned on. This smell is caused by high humidity levels in the air in your home. When moisture mixes with dust and dirt in your ductwork. It leads to mold growth and creates a musty smell that can be unpleasant.

To avoid this problem, ensure that your filters are clean. And that there are no leaks or cracks in them or anywhere else in the system. In addition, it’s essential to have your ductwork regularly inspected for signs of mold or mildew growth and to have it cleaned if anything is found. The same goes for your HVAC unit itself. If there is any visible mold or grime on the unit, call a professional for AC service in Roswell as soon as possible.

When Your HVAC Smells Like Burning Dust

If it only gives off a burning smell temporarily, then it’s likely just burning off dust built up in the unit. However, this smell can also indicate something more serious, including a wiring issue, an issue with an electrical component, or even a mechanical problem with the compressor.

Don’t ignore the problem if you notice this smell when you turn on your HVAC system. Instead, call an expert to inspect and clean these areas, ensuring there’s no damage to your system over time.

When Your HVAC Smells Like Rotten Eggs

If you smell rotten eggs in your house, it could signify a gas leak or another dangerous leak in the system.
