“We’ve noticed a bad smell coming from our air conditioning unit. It seems to be much worse at the back of the house, near the main bedroom. We always have our unit serviced regularly so we’re really not sure what could be causing this smell?”

Experiencing unpleasant odours emanating from your air conditioner can be both uncomfortable and concerning. This detailed guide will explore the common reasons behind why your air conditioner smells and provide effective solutions to ensure your living or working environment remains fresh and healthy.

Understanding Why Your Air Conditioner Smells

There are numerous causes for a smelly air conditioner and for each cause, there can be a different solution.

Common Causes of Air Conditioner Odours

  • Musty Smells: A musty scent often indicates the presence of mould or mildew within the system. This is usually due to moisture accumulation, providing a perfect breeding ground for fungi.
  • Fishy Odours: An air conditioner smelling like fish could signal electrical issues. When plastic components or insulation wires overheat, they can emit a fishy or burning scent.
  • Dirty Sock Syndrome: This unpleasant smell is reminiscent of dirty laundry or bad foot odour, typically caused by stagnant water and bacteria buildup in the system.
  • Exhaust Fumes: Mechanical failures can lead to a leakage of fluids, giving off an odour similar to exhaust fumes, although air conditioners don’t operate on gas.
  • Gun Powder Smell: A sharp, acrid odour similar to gunpowder can indicate an electrical fault, such as a shorted circuit board or fan motor.
  • Dead Animal Smell: Unfortunately, small animals can sometimes enter the ductwork, die, and decompose, leading to a very distressing odour.

Health Risks Associated with Neglected Air Conditioners

Ignoring a bad smell from your air conditioner isn’t just unpleasant; it can pose health risks. Mould, mildew, and bacteria can cause respiratory issues, allergic reactions, and flu-like symptoms, emphasizing the importance of addressing these odours promptly.

How to Get Rid of Bad Smell from Air Conditioner

Professional Cleaning and Maintenance

The most effective way to eliminate and prevent odours is through professional cleaning and maintenance. At PenAir, we use Aerisguard, a biodegradable, multi-enzyme cleaner designed to cleanse the fan coil thoroughly. Following the cleaning, we treat the filter with a non-toxic product to prevent the recurrence of mould and bacteria, ensuring your air conditioner remains odour-free.

Preventing Mould and Moisture Buildup

Regular air conditioning maintenance is key to preventing mould and moisture, the primary culprits behind musty smells. Ensure proper drainage of the unit and replace filters regularly to maintain clean, dry conditions within the system.

Addressing Electrical and Mechanical Issues

If your air conditioner smells like fish or emits a gunpowder-like odour, it’s crucial to call in professionals immediately. These smells can indicate serious electrical or mechanical issues that pose safety risks.

Cost Considerations for Air Conditioner Cleaning

Understanding the cost involved in servicing and cleaning your air conditioning unit can help you budget for this essential maintenance. PenAir offers transparent pricing based on system accessibility and whether one or two technicians are required. Our prices are competitive, and we provide discounts for existing clients and members of our air conditioning maintenance programme.
