When living in Texas, the summer months are scorching hot and humid, and the last thing you want to be without is cool air. One way to tell that you may need an HVAC repair is if you smell something unusual coming from your unit. There are various smells your HVAC could produce, each indicating a different problem. Please browse the following section to explore the different HVAC smells and what they mean. When you smell something funky, it is essential to call an HVAC contractor before your problem worsens.

Rotten Eggs: When your HVAC system smells like rotten eggs, this usually indicates that there is a natural gas leak. You must call a professional as soon as possible when there is a rotten egg smell. Gas leaks are hazardous and can lead to an explosion if not handled timely.

Musty: If your HVAC system has a must or mildew scent, you could have a buildup of mold in your system. When moisture isn't draining properly in your unit, it will become a breeding ground for mold. Mold can significantly affect your indoor air quality and the health of those in your home or business, so you will want to call an HVAC contractor as soon as possible.

Smoke: A burning smell from your HVAC system is never a good sign. If something inside your system is burning or overheating, it will give a smoke smell throughout your property. A damaged motor or frayed wire could be causing this smoke smell.

Oil: The main reason you could be smelling oil from your HVAC system is if you have an oil leak. Oil leaks are an easy fix, but an oil smell could also indicate a damaged oil burner or clogged pump. A professional will determine what is causing the oil smell and find a dependable solution.
