What Is That Smell Coming From My Air Conditioner?

Have you recently noticed an unusual smell wafting from your air conditioner’s indoor unit? Is it enough to make you pause and worry about what could be wrong? 

Odors from your AC unit can signal a range of issues that affect both the efficiency of your system and possibly your health. At Johnson & Johnson Heating and Air Conditioning, we specialize in diagnosing and resolving all sorts of HVAC issues, including those mysterious smells. 

Understanding the Source of Odors

If any of these strange odors waft out of our air conditioning unit, don’t hesitate to call us for help.

Mold and Mildew Accumulation

One common source of smell is the growth of mold and mildew within your system. Fungi thrive in moist environments, often resulting from condensation within the unit. Regular inspection and maintenance are crucial to clean these areas and prevent spore buildup, which can impact air quality and health.

Blocked Drainage and Standing Water

If the drainage system of your AC unit gets blocked, water can accumulate and lead to mold or mildew and a distinctive musty odor. Standing water can also become a breeding ground for bacteria, adding to the smell problem.

Refrigerant Leaks

The chemical odor, similar to the smell of paint thinner, can indicate a refrigerant leak. Refrigerant, previously known as Freon and now commonly known as Puron, is essential for your AC to produce cold air. Leaks not only cause your system to underperform but can also pose health hazards if not addressed promptly.

Decaying Organic Matter

Sometimes, small animals like rodents can get into the outdoor unit and, unfortunately, die, causing a decaying odor. Removing animal debris is essential not only to eliminate the smell but also to prevent your system from overheating and malfunctioning due to blocked airflow.

Overheating Components

Electrical malfunctions or overheating motors within your AC unit can emit a burning smell. This odor should not be ignored as it indicates a serious problem that could lead to a system breakdown or fire hazard.
