Have your Air Conditioning System professionally cleaned

Making sure your air conditioning system is clean and working correctly has a number of health and energy-saving benefits apart from the obvious need to protect the longevity and durability of your system by keeping it clean and properly maintained.

For instance, a study into heatwaves in Australia have shown that during 2000 – 2009 over 500 people have fallen victim to heat exhaustion. This figure which does not even fully capture the magnitude of the problem. Many more deaths have heat as a contributing factor but not the main cause. Keeping cool with an efficient air conditioner is the best means of preventing heat-related deaths and illnesses.

Below we have listed some of the main benefits of having your Air Conditioning system professionally cleaned.

Top 10 Benefits of Having your Air Conditioning System Professionally Cleaned

By Brisbane Top Rated Air Conditioning Cleaning Services Professionals

To ensure you’re getting the most out of your air conditioning system, make sure you have it professionally cleaned. Let’s look at the top 10 reasons why a professional clean is so important and how it will benefit you.

1. Reduces ENERGY bills

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system’s efficiency significantly.

With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil’s heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner’s energy consumption by 5% to 15%.

2. improves AIR QUALITY

Air conditioners circulate and filter air, removing pollutants and mould from the air. This is especially important for people who suffer from allergies and asthma because it minimises the irritants that trigger an attack.

This only hold true, however, if your system is kept clean and filters are regularly changed. Otherwise, your AC can actually contribute to indoor air pollution.


Your AC filters also keep out insects and are far more effective than having open windows with or without a screen.

Insects are not only annoying and inconvenient, but they can also be dangerous to people with allergies and pets. A good air conditioning system can help keep indoor pets flea and tick-free.


We’ve all experienced the mental sluggishness that comes with a day that is just too hot.

There’s actually a scientific basis for this. According to an article in the Scientific American, the energy the body expends trying to cool itself down takes away from our ability to think and reason. When offices are air conditioned, people are able to work better and make better decisions.

5. COOLER TEMPERATURES help regulate mood

It’s not just our brains that suffer from the heat either. When the mercury rises so do tempers.

As an article on explains, while our brains are slowing down, our bodies are speeding up with increased heart rates and higher blood pressure. All this leads to more aggressive behaviour making a cool environment key to maintaining peace at home, work, and in public places.


Those same physical changes – higher heart rate and blood pressure – that make us angry can also make it next to impossible to get a good night’s sleep.

One’s core body temperature is also a critical factor in getting to and staying asleep. A too hot (or too cold) room interferes with natural temperature regulation which doctors say functions best at between 18 and 24 degrees celcius.


Heat, and especially the humidity that often accompanies it, can wreak havoc on furniture of all kinds.

Wood gains and loses moisture with the air around it which over time leads to warping. Leather also absorbs moisture which could eventually cause that stylish couch to rot. And any fabric is susceptible to the mold that breeds rampantly in damp environments.


We’ve already discussed how open windows, even with screens, are limited when it comes to keeping bugs out. They’re even worse at keeping out unwanted people.

Depending on where you live or work, an unsecure window or door simply isn’t safe. You want to keep your loved ones and valuables protected from both the elements and the unpleasant side of humankind. According to statistics on, 1 in 10 burglaries in Australia involve the offender confronting someone in the home. 40% of all burglaries happened through an unlocked door and 28% through an unlocked window.


This pales in comparison to many of the other issues, but the heat can be murder on your clothes and furniture.

Unsightly discoloration from sweat can cause serious embarrassment and send a favourite shirt to the rag bag. Additionally, it can totally ruin your favourite furniture including couches, mattresses, upholstered seats, matresses, pillows, cushions and wooden furniture. Keeping cool with a central air conditioning system can help preserve your wardrobe, furniture and your budget.

10. Extend the life of your air conditioner

Like servicing your car, your air conditioning system should be maintained to ensure its longevity.

Regular maintenance and cleaning will keep your system functioning at its peak even in extreme conditions and as a result, prevent breakdowns. When the system’s been cleaned, all loose parts have been tightened, stiff parts have been lubricated, and broken or damaged parts have been replaced, there’s very little chance an emergency repair will be needed.

Like any system, when one section fails to perform properly, it puts added stress on other components leading to more problems. Make sure your air conditioning system doesn’t let you down when you need it most.

Steps to cleaning your air conditioning unit:

  1. Make sure the unit is isolated either at the isolator and/or by switching off the circuit breaker at the switchboard. This is extremely important to avoid electrocution.
  2. Remove filters from the indoor unit. Give them a good clean using warm water to remove all the dust.
  3. Place air-con cleaning back underneath the unit.
  4. Open the front cover. This will require removing screws. Be careful not to break anything.
  5. Spray coil cleaner and fan barrel with coil cleaner. Refer to manufacturers guides.
  6. Rinse coil cleaner with a water spray. The drip pan should catch most of the water. This step should be taken to avoid wetting any electronics.
  7. At the outdoor compressor unit, rake leaves and/or debris away from the unit. Having a leaf blower may be quicker and easier.
  8. Let all the water recede into the bag, re-install front covers and filters.
  9. Turn the unit back on. Please note these steps are to be taken at your own risk. We recommend contacting a professional to ensure the job is done safely and without causing damage to your system.

An air conditioning system delivers cool air into your home. A ducted system will also draw out the warm air to maximise the cooling process.

A split system air conditioner works a little differently to a ducted system. Split systems utilise a compressor to condense and circulate the refrigerant through the outdoor unit, changing it from a gas to a liquid. The liquid refrigerant is then forced through the indoor evaporator coil or cooling compartment. Then, the indoor unit’s fan will circulate the inside air to pass over the evaporator fins. The evaporator’s metal fins exchange the thermal energy with the air around it. There, the refrigerant turns from liquid into vapour, removing any heat from the surrounding air. As the heat is removed from the air, the air is cooled and blown back into the house.

From that point, the condenser or the outdoor unit then turns the refrigerant vapour back into a liquid, removing any heat. By the time the liquid leaves the evaporator again, it is a cool, low-pressure gas, eventually returning to the condenser to begin its trip all over again. This process is repeated until your home (or thermostat) reaches the desired cooling temperature.

A general rule to follow is twice a year but just remember that it depends on a few things like:

  • how frequently it is used
  • the type of system being used (ducted, split system, etc.)
  • how big the system is in relation to to the space you’re heating and/or cooling

The most important thing to consider is the overall use of the air conditioning system. If you have a small system heating a large area, it will work harder compared to a larger system working to cool the same space. As a result, the higher air intake and stress on the smaller system will require more attention.

If your air conditioner is well maintained and kept clean, it will last far longer than a neglected system. Regular maintenance will prevent costly repairs damage to other components.
