Air Conditioner Musty Smell

A musty or bad smell from your air conditioner probably means you have mildew or mold growing at your air conditioner cooling unit with spores likely growing and spreading throughout your home whenever your air conditioner is turned on. Mould is dangerous to your family’s respiratory health and now is the time to clean the source of the mould. Mould can grow in warm, humid, dark areas, such as the finned coil in your inside cooling unit. However, for mould to exist and grow, giving off a bad musty smell, it needs dust and dirt and the organic things that exist there.

The most common cause of growing mould is dirt lodged in the finned coil, the condensate that is produced at the coil is a great means to catch dirt and all these organisms. Another likely source is found at the drain tray pipe. If this is blocked, water will build up and promote the growth of these harmful spores. If you have mould growing, shut down the air conditioner unit and call Local Air Conditioning Repairs without delay.
