What is the Impact of Bad Odour?

When your AC smells bad, it may indicate some underlying issues such as bacterial and mould buildup. This will not only affect the AC unit’s efficiency but its performance and lifespan.

What are the Reasons for the Bad Smell Coming from the AC Unit?

There are several reasons why does air conditioner smell bad. Some of them have been described in detail below:

• Accumulated Moistness: One of the biggest reasons behind a smelly AC system is the excessive build-up of dampness within the AC unit. When the AC unit is unable to drain that moisture, it will create a breeding ground for bacteria, mildew, and mould. When these micro-organisms accumulate, they will emit a divergent musty smell. This bad odour will permeate the air within your space.
• Blocked Drain Lines: The condensation drain lines in the AC units carry away the excessive moisture. When time passes, drain lines will be filled with algae, debris, and dust. This will ultimately block the water flow which will lead to a foul smell.
• Dirty Filters of the AC: Cleaning the air filters of your AC unit is necessary to maintain fresh air and a clean environment. Over time, these air filters will collect allergens, dirt, and dust. As a result, it will affect the airflow. When this happens, odour-causing mould and bacteria will start breeding. As soon as the air passes from these dirty filters, you will smell bad odour. Thus, you are advised to keep the air filters of the AC units installed in your space to eliminate potential bad smells.
• Decomposing of Organic Materials: Many times, you will noticea decaying or rotten smell coming from the AC. This is because of dead animals, rodents, insects, and even leaves inside the AC units. When these organic materials start decomposing, you will bgin experiencing a foul smell. Hence, check for these to know if these matters are the reasons for the bad odour or not.
