Are You Bothered By The Noise Of Your Air Conditioner?

When it comes to air conditioners, comfort and cost are the things that immediately come into our minds. But, do you know that there is another factor we should consider?


So, are you bothered by the noise of your air conditioner?  Read some of our tips on how this can be avoided.

Read the specifications carefully

Trying an air conditioner before actually purchasing it is impossible. So, how do you know if its noisy or not? Read the specifications.

The noise level of an air conditioner is measured in decibels. Usually, this information is always included in the product’s specification. You shall see two numbers that indicate the noise level that the unit makes when inside a home, and the other one is for the exterior noise.

If you don’t or can’t see it, make sure to inquire with the dealer.

To give you an example, 20 dB is close to hearing a whisper, while a 40 dB is like the ambient noise in a park or residential place. Therefore, when talking about the interior noise of an air conditioning unit, depending on its capacity, 35 dB is a reasonable interior noise for a split type system.

Now, for the exterior noise, it shouldn’t be higher than 5 dB. It shall not be louder than the typical ambient noise in the area. Therefore, the quieter the unit’s exterior noise, the better.


Take note of strange sounds

If you have an air conditioner for quite a while now, then you’re already accustomed to its noise while working. However, if you hear strange or different sounds; then you should be alert.

Below are some of the sounds you’d want to take note of that may indicate there is a problem with your unit. Should you hear any of these, call an air conditioning specialist immediately.



You need to be concerned if this is the sound you hear from your unit. This means that there’s a serious problem with it. The dual-shaft motor or an essential bearing might be breaking down, which is something you shouldn’t ignore.



Hearing this sound can either mean a minor or a major issue. A minor issue can be an air return leak, while a major issue can be a leak in the unit’s refrigerant. So, definitely, you should be bothered and call an air conditioning specialist if you notice this from your unit.



If the humming noise from your unit gets louder than usual, then the dust and debris may have already build-up inside. But, if it has become strangely too loud, it may indicate that the capacitor of your unit is now failing, which is a serious problem that needs immediate attention.



Should you hear a rattling sound from your air conditioning unit, you should stop it and call a specialist. This means that the fan rotor has loosened.



A squeaking noise is less of a worry than the other noise. It can only mean that your air conditioning unit needs cleaning or lubrication.


Consider the installation of the unit

Carefully considering where your air conditioning unit will be installed will have a good pay off, especially for your outdoors. Typically, there are guidelines of acceptable noise of air conditioning units in local residential areas.

So, you won’t need approval from your local area’s Council for the placement of your unit. However, if you’re in strata-managed units, make sure to talk to property management to check the by-laws first before installation.


Invest in new air conditioning units

When it comes to the noise of an air conditioning unit, both inside and outside, it largely depends on the following:

  • Age
  • Model
  • Make of the unit

These things may be hard to spot when you’re shopping for an air conditioner. Thankfully, Daikin placed a big effort in making quieter air conditioning units. Their cooling units now include aerodynamic fan blades, air grilles, and the latest compressor technology to provide a more efficient air conditioning experience at a quieter operation.

So, if you want a better cooling experience with an almost whisper-like noise, then it’s time for you to check Daikin’s Quiet Operation function in their air conditioning systems. Call us now. We’ll be glad to help you get the best deal of cooling systems for your home.


Keep a regular servicing schedule

To prevent your air conditioning unit from having the problems mentioned above, you need to keep to a regular servicing schedule. This way, your air conditioning specialist will be able to spot and fix any problem before it gets worse.

Do you hear any of these noises from your air conditioner?

Why You Should Choose DAIKIN Heat Recovery Systems for Your Commercial Property in QLD (Part 2)

In our previous blog, we discussed Daikin’s Variable Refrigerant Volume or VRV system. Today, we will move the discussion towards Daikin’s VRV IV + Heat Recovery System. We will also share how this technology can help many companies in Queensland.

What is Daikin VRV IV?

Daikin VRV IV is the most advanced version of the Variable Refrigerant System. Some of the exclusive features in this version include:


Variable Refrigerant Temperature

Energy efficiency is the trademark of Daikin VRV System. However, energy consumption has never been as efficient with VRV IV as compared to other versions. VRV IV has an additional feature called variable refrigerant temperature.

This advanced feature allows the VRV system to adjust its performance based on the climate condition and building requirements of the area where it is installed. This will have a huge impact on energy efficiency as the system automatically adjusts to the seasonal changes.

In the past, the VRV system needed to be adjusted as seasons change to minimize energy consumption when it is less needed. The adjustment service will be added to the company’s expenses. Now that VRV IV can adapt its performance to the environmental condition, there will be lesser fees and more energy efficiency.


Optimized installation

If you are familiar with air conditioner control modules, you will understand that more AC control modules require more piping and electrical works. VRV IV, however, allows up to three control modules in one piping system. That means lesser piping and electrical connection requirements.

It is also good to note that a single AC control module of VRV IV now has a 14 tons capacity. You can further maximize up to 34 tons capacity in three modules using only a single piping network. This is the most optimized VRV installation we have offered so far.


VRV IV is easier to install

With the easier installation procedure for the latest VRV system comes faster installation service. This entails that you will pay less for installing VRV IV than other VRV systems.


What is the Daikin Heat Recovery System?

The heat recovery system is another product of air conditioning technology brought by Daikin. It is an energy-efficient and environmental-friendly solution to air conditioning.
Going back to our previous blog, we mentioned the VRV system as both a heating and cooling system. However, we have yet to explain how VRV can act as a heater. That is because the heating mechanism of the VRV system lies in the heat recovery feature.

Heat recovery is a process wherein the indoor component of a VRV system, particularly VRV IV, collects the warm air in a given space. This warm air is then deposited to certain rooms which require warm air. Thus, it doesn’t make use of heating coils to produce warm air. It doesn’t produce heat energy for heating at all. It merely redistributes the warm air from one place to another.

The heat recovery system is therefore an energy-efficient way of heating an area. Using VRV IV + Heat Recovery System is, therefore, not only lowers energy consumption but also lessens the carbon footprint.



We are happy to be one of the few trusted DAIKIN contractors licensed and authorised to install the Daikin’s VRV and Heat Recovery System. Look at one of our projects using this.


Noosaville Project

We are pleased to be offering the bounce backpackers at Noosaville our services, full car park and exhaust ventilation system with Daikin heat recovery systems and split systems.

These advancements in air conditioning technology provide a very promising convenience for businesses in Queensland. Not only will they help with the corporate expenses but also pave the way to a greener economy.

3 Types of Air Conditioners For Townhouses in QLD (Part 2)

We discussed one of the three types of air conditioners which are ideal for townhouses in the previous blog. A split type air conditioner has a lot of benefits but not all types of house layout can benefit from it.

If a split type of air conditioning system is not the right type of air conditioner, then we’ll share you two more options in this blog. Let’s start with a multi-split air conditioner.


What is a multi-split type air conditioner?

A multi-split air conditioner is similar to a split air conditioner. It also has an indoor and outdoor component. The only difference is that a multi-split type has a single outdoor component connected to several indoor units. This means that you will only need a place for one outdoor unit when you need ACs for different rooms.


Why is a multi-split type air conditioner fit for a townhouse?

A multi-split type AC has a single outdoor component which means less space requirement. It also consumes less energy, which makes it more energy-efficient, compared to other types of air conditioners. They produce lesser noise compared to what you may experience from other AC systems. However, the indoor component’s noise varies from one brand to another. So, if you want a not so noisy air conditioner, it is best to choose the modern models of aircon, particularly DAIKIN.


What’s the downside of multi-split type AC for townhouses?

One downside of a multi-split type air conditioner is that the indoor component occupies quite some space. The indoor component may not fit in small rooms.


What is a ducted type air conditioner?

A ducted type air conditioner has a single outdoor component, much like a multi-split. However, the indoor parts aren’t rectangular components but air ducts.

The outdoor component of a ducted air conditioner is often placed on the roof of the house and the ductworks are located inside the ceiling. Thus, the cool and warm air (when a reverse cycle is used) will be distributed in the rooms from holes or slits on the ceiling.


Why is a ducted type air conditioner fit for a townhouse?

Ducted type air conditioners work similarly to the multi-split type. Therefore, it is also applicable to any spot in a townhouse. Moreover, you will not have to worry about finding a place for the outdoor unit. Since it is typically placed on the roof, the space requirement wouldn’t be a problem.

Noise level for ducted air conditioners is significantly low. This makes it perfect if you have nearby neighbours who wouldn’t want to be disturbed because the air ducts produce almost inaudible sound.


What’s the downside of ducted type AC for townhouses?

Despite the many conveniences of a ducted type air conditioner, it also has some disadvantages. For instance, a ducted air conditioner can be costly. It is the most expensive of the three options. The installation is also critical and costly. Lastly, it requires a space in the ceiling for the air ducts and may not be suitable for all interior layouts.

However, the benefits it delivers outlasts the disadvantages. Just look at a boutique apartment where we have installed ducted AC units.

These are the three types of air conditioner which are perfect for townhouses. Each one has its benefits and disadvantages. You should consider which among the three will be the most suitable based on your property’s requirements.

Why You Should Choose DAIKIN Heat Recovery Systems for Your Commercial Property in QLD Part 1

Daikin has been known as the forerunner in air conditioning technology. One of the many innovations in air conditioning that was created by Daikin is what we call VRV + Heat Recovery System. Invented in 1982, VRV system solved the problems with huge energy consumption for establishments that make use of many air conditioning units for their day by day operations. As years passed, it was further developed with an infused heat recovery solution.

Today, we will discuss the prototype of the VRV IV + Heat Recovery System to better understand its advantages. This blog will focus on Variable Refrigerant Volume or VRV systems.

Come to think of it, there was only one option to cool a whole building in the past. That is to install several air conditioners in different areas and have them run simultaneously. However, you could only imagine how much that could blow up your energy bill. This is not to mention the cost for maintenance and repair which comes with having an air conditioner.

This problem was solved when Daikin introduced the first and only VRV system as an air conditioner for commercial spaces.

 Since Variable Refrigerant Volume is a trademark of Daikin, other companies’ version of this technology is called Variable Refrigerant Flow. Therefore, if you are specifically looking for Daikin’s system, it will help not to confuse the two.
Now, what is a VRV system and how does it work?


What is the Variable Refrigerant Volume or VRV System?

VRV system, as its name suggests, is an AC system that utilizes refrigerant in cooling and heating several rooms at once. The technology is very similar to a multi-split ductless air conditioning system but has relatively low energy consumption. Thus, it is very ideal to use for commercial establishments.


What are the important features of a VRV System?

Variable refrigerant volume system has a lot of features that make it an ideal air conditioning solution to large spaces. Some of which are as follows:

  • VRV system has multiple indoor units connected to a single outdoor component much like a multi-split air conditioner.
  • The outdoor unit receives signals from each indoor unit and delivers the required air temperature back to each indoor unit accordingly.
  • The VRV system can be used for a heating and cooling system simultaneously. That means if one of the ten rooms requires a heating system. The outdoor unit will process nine rooms with chilled airs and one room with warm air. No need for manual adjustments.
  • The VRV system has sensors which can detect if the rooms are occupied. When one room is vacant, the outdoor unit will shut its operation on that particular room.
  • This air conditioning solution promotes energy efficiency and significantly decreases the carbon emission for huge establishments.


How does the VRV system work?

The Variable Refrigerant Volume system uses refrigerant for both cooling and heating processes. The refrigerant inside a VRV system is being conditioned by multiple condenser units. The conditioned refrigerant will then flow from the outdoor unit to indoor units scattered throughout the building. This allows for simultaneous air conditioning using a remote control system.

The indoor units, on the other hand, will determine the required temperature for their respective rooms. They can also detect when the room is unoccupied. All these conditions will be sent as signals to the outdoor component. With this setup, energy consumption will be limited. VRV technology allows for zero waste energy consumption in commercial properties.

3 Types of Air Conditioners For Townhouses in QLD (Part 1)

Townhouses are among the popular types of residential property in suburbs like Queensland. It can be shared by three or more families, which makes setting up an air conditioner for each of these units can be challenging.

Here are some problems you may encounter: 

  • limited areas to place certain types of air conditioner like window type ACs
  • some air conditioners can be very noisy which might cause disturbance for your neighbours
  • some areas in Queensland have protocols for noise limits
  • limited ceiling space (in case of ducted air conditioners)
  • the number of rooms which will need an air conditioner
  • the layout of the house

With limited options, it can be difficult to find the best type that will work for you. So, we have shared with you in this blog your different options and the factors you should consider in choosing the best one for your requirements.

What is a split type air conditioner?

A split type air conditioner has two components, an indoor and an outdoor. The indoor unit is a rectangular component that is often mounted on walls. This indoor unit is then connected to the outdoor unit by pipes.


Why is a split type air conditioner applicable in a townhouse?

Whether you live at the end or middle part of a townhouse, installing a split type air conditioner isn’t a problem. The problem with a window type air conditioner is that it requires space on the exterior wall.

This is impossible for the middle part of a townhouse since the walls are shared with your neighbour. A split type AC’s outdoor unit, however, can be placed on the ground or the balcony. The piping that connects the indoor and outdoor unit requires very little space.

Most split type air conditioners also produce very little noises. Split type air conditioners are widely used in Queensland because they are relatively quiet compared to other types.

Split type air conditioners are also ideal for interiors with an open layout. Should you have an open layout for both the ground floor and upper floor, you’ll only need two split types ACs.

What’s the downside of split type AC for townhouses?

The only downside of a split type air conditioner is that every indoor unit requires an outdoor unit. Therefore, when you need to run several split type air conditioners for different rooms, it will require more outdoor units.

Running several air conditioners can be very expensive. First, it will surely have a toll on your electricity bill. Another thing is the additional charges for regular maintenance and repair. It may also not comply with the body corporate bylaws.


Is a split type air conditioner not the convenient one for your spot in the townhouse? Or is your town house’s floor plan not very ideal for a split type air conditioner? This is just the first part of our two blog series. Do follow us to know the other options you may have. This includes the most popular choice of air conditioning system chosen by our clients in Queensland. 

For now, let us leave to you a video of our recent townhouse project:



Why it is important to keep schools HVAC working efficiently (Part 2)

In our previous blog, we discussed the negative impact of poor ventilation on the students’ learning condition. We also shared how air conditioners can help solve the problem of poor ventilation in schools. Moreover, we mentioned that aside from insufficient AC units, schools in Queensland are facing another AC problem: poor maintenance.

The sufficient ratio of air conditioners and facilities is a good thing. However, for the school to be properly ventilated, the air conditioning units must be regularly maintained. In today’s blog, we will share with you the benefits of giving the school air conditioners proper maintenance.


Why does an air conditioner need maintenance?

Air conditioners filter dirt and dust in the air as they provide the room with a cool temperature. These particles are accumulated in AC filters. Thus, when you check your air conditioners at home, the filter gets dirty after some time.

The same goes with the air conditioner filters in the school, maybe even worse. When left unattended, the dirt can clog the filters and air conditioners will start to malfunction. 

Another common problem of air conditioners is frozen coils. This happens when air conditioners are running continuously over time. In classrooms where the air conditioners work non-stop, it is typical for the inner system to freeze. Such problems can shorten the air conditioner’s lifespan. However, these issues can be avoided with regular maintenance.


How does air conditioner maintenance work?

The first thing you need to keep in mind is that air conditioner maintenance is essential. Another thing is that it must be done by professional and licensed HVAC technicians only. Why? It is to ensure that your air conditioner will be properly cleaned and free from damages.

Now, how do licensed HVAC technicians do air conditioner maintenance?

Air conditioning maintenance involves the following tasks:

  • Inspection of the whole unit for possible damages and risks
  • Cleaning and replacing the filters
  • Cleaning the evaporator and condenser coils
  • Fixing and dusting the air conditioner’s fan
  • Checking and replacing refrigerants
  • Removing dirt and debris trapped inside the outdoor unit
  • Cleaning air ducts

Most of these tasks require professional experience. The last thing we want is for the dirt to be deep-seated that it is difficult to clean. This is mostly the case when the air conditioner is poorly maintained.


How frequent should school air conditioners get maintenance?

Air conditioners must have a thorough maintenance service at least once a year. However, in schools where air conditioners are more frequently used, maintenance should be done more often. It is advisable to get the air conditioners maintained before the start of every term. It will ensure that the air conditioners will not fail during the whole term.


What are the benefits of properly maintained school air conditioners?

Most of us think that air conditioner maintenance is expensive. That’s why we are sceptic of getting regular maintenance for our schools’ many air conditioning unit. Surprisingly, proper and regular air conditioning maintenance has a lot of benefits including:

  • Clean and germ-free air
  • Limited instances of air conditioner emergency
  • Longer lifespan
  • Lesser need for repairs
  • Less energy consumption

With all these benefits, you’ll realize that getting the schools’ air conditioner regular maintenance is the less expensive option. Repairs and replacement are, after all, more costly than the maintenance fee.
