1. Car ExhaustYou might be wondering why does my HVAC smell like car exhaust? It can create an odor reminiscent of car exhaust fumes when your HVAC leaks fluids.

A leak in your refrigerant line can lead to a severely downgraded performance in your HVAC. Additionally, chemicals leaking can be hazardous to you and the environment.
2. Rotten EggsIf you smell rotten eggs or sulfur in your home, it’s most commonly attributed to a natural gas leak and should be taken very seriously. You’ll need to open your windows, shut off the natural gas source, and call the gas company and an HVAC specialist. A pest problem, a dead animal in the attic, or your ventilation system could also be the source of the smell. You’ll need a pest control service if this is the case. They’ll remove the live pests as well as the dead ones.
3. Chemical OdorsSeveral different things can cause chemical odors to come from your HVAC. These are the most common causes:
- The AC is malfunctioning: If you smell chemicals like formaldehyde or paint thinner, you need to have a professional HVAC technician inspect your unit. Because of the multitude of chemicals used within an HVAC, it can produce a variety of smells when it malfunctions.
- You have a Freon leak: The Freon within the HVAC system travels in a closed circuit of copper coils and lines, which can crack and leak. You’ll notice Freon’s distinctive sweet smell, similar to your car’s coolant.
- You recently had repair work completed: If you’ve recently had your ductwork repaired, this could account for any chemical smell coming from your HVAC. The glue used for installation and repairs gives off a heavy chemical odor while drying.
- There are open chemical containers near your ductwork: Improperly sealed and stored chemicals can leak, allowing fumes to spread into nearby ductwork. While this isn’t an actual HVAC problem, it’s still a potential health hazard that an expert must fix.
