If you have been keeping up with our posts, you know that we are currently listing out some of the most common smells that are produced by a home’s HVAC unit when something is amiss.

In today’s post, we are going to finish our short list by detailing the smells that should cause the most concern when experienced. Continue reading below to learn more.

Keep Your Home as Safe as Possible


If you are a homeowner, we assume that you want to make sure that your house, and the people who live inside of it, are as safe as possible. A home is a place of sanctuary, a place where a person is supposed to be able to go in order to relax, rest, and forget about the troubles of the world. A relaxing home environment is hard to achieve when your HVAC unit is signaling to you that something is seriously wrong with its internal components. Below, we have listed two of the most concerning smells that can come from your New Braunfels home’s HVAC unit.



  • Rotten Eggs: If you go to turn on your heater and you notice a rotten egg smell coming from your vents, leave your home. We aren’t kidding. Get out. If you smell rotten eggs, this almost always means that there is a gas leak somewhere in your HVAC system. Although natural gas is odorless, almost all utility providers will add a rotten egg odor to make sure that people are able to tell when the gas is leaking. In this situation, you will need to call an HVAC company, have the gas in your home turned off, and wait until the accumulated gas has dissipated. Even a small spark in a home filled with natural gas is enough to cause the house to explode.
  • Mold: If you have noticed that a moldy smell drifts out of your vents when you turn on your HVAC system, it most likely means that moisture that has gathered in the system has not been properly drained away. While a moldy or musty smell is not dangerous in and of itself as it relates to the health of your HVAC unit, it can cause issues with the indoor air quality of your home. Excessive mold presence in the home can lead to a wide range of health issues including respiratory problems in both adults and children.
