It is a problem familiar to most homeowners. You clean your house from top to bottom, but you still notice a strange odor whenever you walk in the door. The smell may actually indicate a problem with your HVAC system. Some of these odors are a minor annoyance, while others suggest a serious issue requiring immediate attention. The following are a few of the most common HVAC issues that may cause your house to smell funny.
Musty or Moldy Smell
This is one of the most common HVAC problems. Poorly installed systems, clogged drain lines and debris or leaks in your ductwork can allow water to stand in the drain pans. This can lead to mold and bacteria growth in the drain pain or along the coils of your heat pump or air conditioner, which can often be the source of a musty or moldy smell.
A slight burning smell coming from the vents when you turn the heat on for the first time is not unusual. This is simply the dust burning off the heating elements and furnace components. On the other hand, if you smell a strong electrical scent or see smoke coming from the system, your HVAC may have loose electrical connections or overheated parts. You should turn the system off and call for service immediately.
Rotten Egg Smell
Furnaces naturally emit a very slight odor. However, the strong smell of rotten eggs indicates a natural gas leak. This could be a potentially dangerous situation. You should call the gas company immediately. Do not turn on any electrical devices or use your cell phone inside the home as this could cause a spark, and could trigger a potential reaction.
