Signs of Mould in Air Conditioner

If you suspect that your air conditioner may have mould, there are a few key signs to look for. One of the primary indicators of mould is an unpleasant musty smell coming from the air conditioner. 

This smell can be especially strong when the air conditioner is first turned on. Additionally, you may notice visible signs of mould growth near the air vents or on the walls around the air conditioner.

If you observe any of these signs, it is important to take action as soon as possible to prevent the mould from spreading and causing potential health risks.

First, switch off the power to the air conditioning unit and clean the area with a disinfectant or anti-mould product. Then, inspect the unit itself and check all of the filters, grills and coils for visible signs of mould. If you find any, you should take steps to remove it immediately.

Mould can cause a range of health issues and can also reduce the efficiency of your air conditioner. Therefore, it is important to contact a professional to inspect the air conditioner and address the mould problem.

Health Risks and Symptoms, Is Mould Dangerous?

Mould exposure can cause a range of health problems, including allergic reactions, asthma attacks, and even respiratory infections. People with weakened immune systems, such as young children and the elderly, are particularly susceptible to the health risks associated with mould.

The most common symptoms of mould exposure include:

  • Respiratory issues, including coughing, wheezing, and difficulty breathing
  • Nasal and sinus congestion
  • Eye irritation, such as itchy, red, or watery eyes
  • Dry, hacking cough
  • Skin irritation, such as a rash
  • Headache
  • Memory problems
  • Fatigue

If you are experiencing these symptoms, you may be exposed to mould and should seek professional medical advice.

What Causes Mould in Air Conditioners

Mould can grow in air conditioners when the unit is not cleaned and maintained properly. This is because of the moist, damp, and dark environment inside the unit. These conditions are ideal for mould to thrive and spread.

The presence of organic matter, such as dust, dirt, and other particles, can also provide a food source for mould. Additionally, if the air conditioning unit is not regularly serviced and the filters are not changed regularly, then the unit can become clogged which can cause it to be unable to remove moisture from the air properly.

This moisture then condenses on the walls of the unit, creating an environment conducive to the growth of mould. In addition, if the unit’s drainpipe becomes blocked, then the moisture cannot escape and this can create a pool of standing water inside the unit, providing a perfect breeding ground for mould.

Should We Clean Our Air Conditioner?

Yes, absolutely. Keeping your air conditioner clean is essential for preventing mould growth. Regular cleaning will help reduce the amount of dust and dirt in your air conditioner, which can help prevent mould growth. Cleaning your air conditioner also helps improve air quality in your home, making it easier to breathe. 

If your aircon hasn’t been serviced in some time, contaminants build up on the filters, coils and barrel fan, reducing the ability for the system to output air to the indoor area and reach the desired temperature.

Dust, mould and grime also builds up in the condensate tray which will eventually cause leakages. If the air conditioning system struggles to reach desired temperature, it will continually draw more power trying to keep up with demand, increasing the power usage up to 30%.

Benefits of Cleaning Your Air Conditioner

Cleaning your air conditioner has several benefits. First, it can help improve the air quality in your home. Clean air conditioners circulate cleaner air, which can help reduce the risk of respiratory illnesses. Clean air conditioners also reduce dust and dirt in the air, which can help reduce allergies and asthma symptoms. More benefits to keeping the air conditioner clean include:

  • Improved indoor air quality
  • Reduced energy costs
  • Increased system efficiency and lifespan of the system
  • Reduced risk of breakdowns
  • Improved cooling and heating performance

 

Keeping up with regular maintenance of the air conditioning system is very important. Making sure to check and clean the system regularly will keep you comfortable, prevent respiratory related illnesses and save your valuable time and money on expensive repairs and breakdowns.

How to Prevent Mould in Air Conditioners

Mould in air conditioners can be prevented by taking the following steps:

1. Keep the evaporator coils clean. The Evaporator coils are the coils located inside the unit that cool or heat the air before it is distributed indoors. Keeping these coils clean will ensure the air conditioner functions properly and prevents the accumulation of mould.

2. Clean the air filter regularly. The air filter is responsible for trapping dirt and dust particles, which can cause the growth of mould if left unchecked. Cleaning the air filter regularly will help keep mould away.

3. Check for leaks. If there are any leaks in the system, it can create a warm and moist environment that is ideal for mould growth. Make sure to check for leaks periodically and repair them as soon as possible. More on how to stop and prevent air conditioner leaks can be found here.

4. Ventilate the room. Proper ventilation is important to reduce the humidity levels in the room. This will help to keep the air conditioner free from moisture and reduce the chances of mould growth.

5. Perform regular maintenance on the system. It is recommended to have the air conditioner serviced at least once per year.

What to do If You Find Mould in Your Aircon

If you have discovered mould in your air conditioner, it is important to take action as soon as possible. Mould can cause respiratory problems and other health issues, so it’s best to address the problem quickly. 

The first step is to turn off the air conditioner and open up the unit to identify the source of the mould. 

Once the source of the mould has been identified, it should be removed, and any affected areas should be thoroughly cleaned and disinfected. If the mould is severe, it may require professional treatment to properly remove and prevent further growth.

Once the mould has been removed, it is important to take steps to prevent future growth. This can include regularly cleaning and maintaining the air conditioner, ensuring that the unit is properly ventilated, and cleaning filters regularly.

If the mould is extensive or if you are unsure how to handle the issue, it is best to call a professional. A qualified technician can inspect the air conditioner and determine the best course of action, whether it is a thorough clean or professional mould remediation. A professional can also provide advice on how to keep the mould from returning in the future.

Professional Air Conditioner Cleaning Can Help
