Emission of Strange Smells from the AC unit

Air Conditioners

With the summer heat approaching, it’s essential to have a well-functioning air conditioner. However, many people face common air conditioner repair issues that can make their systems less efficient or even harmful to their health. One such issue is the emission of strange smells from the air conditioner. In this article, we will discuss the causes of these odours and how ALP Heating can help resolve them.

Causes of Strange Smells from Your Air Conditioner

Mould and Mildew Growth

The primary cause of strange smells from your air conditioner is the growth of mould and mildew within the system. When the air conditioner cools the air, it also dehumidifies it. This process creates condensation, which can lead to moisture buildup in the system. If the moisture is not adequately drained, it can create a perfect environment for mould and mildew to grow. These microorganisms produce a musty, damp smell that can be harmful to your health.

Dirty Air Filters

Another cause of unpleasant odours coming from your air conditioner is dirty air filters. Over time, dust, dirt, and other debris can accumulate on the filters, which can lead to reduced air quality and unpleasant smells. In addition to affecting the air quality, dirty filters can also cause your air conditioner to work harder, leading to higher energy bills and potentially shortening the lifespan of your system.

Burning Smells

If you notice a burning smell coming from your air conditioner, it could indicate an electrical problem. This issue can be caused by overheating components, faulty wiring, or a malfunctioning motor. It is crucial to address this problem immediately, as it can be a fire hazard.

Refrigerant Leaks

Refrigerant is a crucial component of your air conditioner that helps cool the air. If there is a leak in the refrigerant lines, it can cause the refrigerant to evaporate and create a chemical smell. A refrigerant leak not only affects the efficiency of your air conditioner but can also be harmful to the environment.
