What’s That Smell Coming from Your HVAC System? An HVAC Repair Company in Addison, Illinois Explains

Have you ever turned on your HVAC system only to be met with an unexpected smell? If so, you are not alone. In fact, there are several different smells that can come from your HVAC system. Are you wondering what these include? This HVAC repair company in Addison, Illinois is going to review these smells and their causes below.

Why Does Your HVAC System Smell Bad?

Musty Smell

Mold and mildew are the most common culprits for that damp, old smell. When your HVAC system pulls moisture from the air but does not drain it out completely, mold and mildew can start to grow inside the unit.

Regular maintenance and cleaning can help prevent mold growth. But if you have cleaned your unit and the musty smell remains, it might be pointing towards a more complex drainage complication. A professional HVAC repair company in Addison, Illinois can provide the clarity and solution you need.

Rotten Egg Smell

This unmistakable smell is often related to a natural gas leak. Even if the source is not directly from your HVAC, turning it on can spread this smell throughout your home.

If you notice this odor, you should immediately shut off your gas supply. Open all windows for ventilation, leave the premises, and then quickly contact your gas company to inspect the situation.

Burning or Electrical Smell

If it smells like something is burning when your HVAC system is on, it is often a sign of an electrical issue. It could be due to overheated parts or even burnt wiring.

If you notice this odor, it’s recommended that you turn off your system immediately and call a professional technician. This is not something you want to handle on your own, as it poses a big safety risk for you and the unit.

Sewage or Rotten Smell

The last thing you would associate with your system is a sewage-like smell. However, plumbing vents can sometimes release sewer gas, which can be drawn into your system and circulated in your home.

A professional technician can usually address this issue. They can inspect the vents, fix any problems, and ensure your system no longer picks up these unwanted odors.

Foot Odor or Gym Locker Smell

Surprisingly, your HVAC system can give off an odor that is somewhat like sweaty socks. In many cases, this is due to stagnant water that has not drained properly, which creates a perfect environment for bacteria to thrive.

It’s important to regularly check and clear the HVAC’s drainage system to prevent water buildup. Having your system maintained regularly by an HVAC repair company in Addison, Illinois can also prevent bacterial growth and the associated odors.

How to Prevent HVAC Odors

While knowing the causes and solutions is essential, prevention is the best approach. You can prevent most of these odor issues by having your unit routinely checked, cleaned, and serviced. Not only will this improve your indoor air quality, but it will also extend the life of your system and keep it running efficiently.
