AC Odors in Chicago, IL

4 AC Odors in Chicago, IL, and What They Mean

June 9, 2023

Chicago has hot and humid summers, which can be a breeding ground for unpleasant odors from air conditioning systems. You can combat these smells with the right preventative measures before they become overwhelming. Here are four different AC odors you should watch in Chicago, IL, and what they could mean.

1. Musty Smell

If you notice a musty smell from your air conditioner, it could mean that biological contaminants are growing inside the system. This can occur due to moisture buildup caused by a clogged drain line. Dirty air filters can also cause this issue, as they can prevent air from flowing freely and allow dirt and dust particles to collect.

2. Burning Smell

A burning smell from your AC unit could indicate an electrical problem. This could be anything from a short circuit to loose wiring; a professional should check it. In some cases, the smell may be due to overheating of the compressor or other components within the system causing poor indoor air quality.

3. Chemical Smell

Chemical smell is a common AC odor and could be due to refrigerant leaks in your air conditioning system. The chemical smell is usually accompanied by warm air from the unit, indicating poor cooling performance. A refrigerant leak can be dangerous, so it’s important to call a professional right away if you smell anything like this.

4. Rotten Egg Smell

A rotten egg smell could indicate the presence of dangerous gases, such as carbon monoxide or sulfur dioxide, which can cause serious health issues if left unchecked. These gases may be from a cracked heat exchanger in the furnace or a gas leak in the system.

AC odors can indicate several issues with your AC system that can be dangerous or cause other problems if left unresolved. If you detect any odors listed above, call a professional immediately.
