How Do You Choose the Best Aircon System for a Small Room?

With more people finding the convenience of working from home due to the pandemic, it is not surprising to note that several rooms inside the house have been transformed into an office space. But to remain productive, one should ensure that the temperature inside these rooms remain regulated. So how do you find the right aircon who can do the job for you?

How Do You Choose the Best Aircon System for a Small Room


Elements to Consider When Buying an Aircon for Small Rooms

When buying an aircon for small rooms in in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes; it is important to note the following elements:


Energy Star Certification

Cooling efficiency is not the only factor you should consider when choosing an AC unit. You should also include its energy efficiency. One way of checking this is by looking at its energy star certification.

Energy Star Certification - small room aircon system


Know that many air conditioners nowadays come with better insulating materials and seals to minimise leakages.


Degree of Noise

No one wants a noisy aircon, much more in a bedroom, especially if it is just a small room. So, we can consider the noise of the unit to be one of the most important elements you should consider.

As a guide, the acceptable noise level for aircon systems in QLD is:

  • 7am to 10pm – no more than five decibels (A) above the background noise level
  • 10pm to 7am – no more than three decibels (A) above the background noise level.

Let us help you choose a quiet aircon system for your small room. Talk to us on 07 3889 4508.


Smart Cooling System

Air conditioning systems have now gotten smarter so that you can control them even if you are away from home. You can even have these interconnected, while some can automatically regulate the temperature for you.

Be smart and choose an AC system that can aid you even if you are sleeping or away from home.


Check the Warranty

Warranty is an important element to ensure you are buying high quality products. However, you should learn more about what’s included in the warranty. Ask your supplier about the do’s and don’ts for you not to get it voided.


Aircon Size

Now comes the aircon size or the capacity you need to cool your small room. This requires a bit of calculation as we have discussed in our previous blog. Some of the elements to be considered are the window location, the height of the ceiling, your floor space and the amount of appliances inside the room

As a rule, if the room is sunny then add a 10% aircon capacity to it, but if its shady then reduce it by 10%. The number of people who frequently use the room also adds to these measurements. So it is always best to consult an AC specialist about it.



For a more accurate sizing of your aircon, it is always best to consult an aircon specialist who can do the calculation for you. They can also help you choose a convenient location to place your aircon and recommend additional measures to help you save on your energy cost. Most importantly, they will be skilled in installing different types and brands of aircon.

How Do You Choose the Right Air Conditioning System for Your Brisbane Offices

If you think choosing the right air conditioning system for your home is tricky, then finding the perfect one for your commercial area is even trickier. This is because of the additional complexity you need to consider when deciding the best HVAC solution to use.

How Do You Choose the Right Air Conditioning System for Your Brisbane Offices


In this blog, we’ll share some industry insights to help you plan and decide your air conditioning installation journey in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes.


What is the ideal temperature for a productive office space?

A plethora of research suggests that office spaces should maintain between 20ºC and 26ºC of temperature, which is also mandated by the Compliance Code for Workplace Amenities and Environment. 

This based on studies that anything lower or higher than this temperature will result in work inefficiencies including increased typo errors. So, it is important for commercial properties and office managers to ensure they achieve the ideal temperature range for their staff to remain productive.


How do you decide the best type of AC system for your office space?

Just like we have mentioned in other blogs, there is no absolute formula when choosing the right HVAC system. This is because the answer to this question rests on these factors;

  • Floor plan
  • Height of the floor to the ceiling
  • Orientation to the sun
  • Office layout
  • Number of people using the space
  • Type of equipments to be used

Based on these elements, your AC specialist can then recommend the right HVAC system to install in your commercial space.


Split, Ducted and Commercial HVAC Systems

For small offices, it’s typical for owners to opt for either a split or ducted system. But this is only recommended for shopping strips or offices converted homes. But for large offices, you’ll find commercial air conditioning systems to be more economical.


Why Choose Commercial Cooling Systems for Large Offices in Brisbane?

Unlike shopping strips and office converted homes, large offices (those with several desks and workstations) require a cooling system that has more power and wider coverage reach to ensure consistency throughout the office. This is the type of HVAC system used in buildings and skyscrapers as it supports dozens of rooms simultaneously.


VRV/VRF Air Conditioning: An alternative solution to large offices in Brisbane

With most offices not needing to run their HVAC system 24/7 to maintain its current temperature, an alternative solution to your air conditioning problem is the VRV/VRF systems.

It works by reducing the amount of refrigerant used whilst the temperature inside the room is stable. This helps in reducing the amount of energy used. The result is as much as 50% savings on your power use. This makes it the more popular option of many commercial areas.


Expert Cooling Solutions for Brisbane Offices

With these variety of choices, you’ll need an HVAC expert who will guide you. Here at Wahoo Air Conditioning, we not only supply and install air conditioning systems to commercial properties such as schools, townhouses, shopping strips and buildings; but we also design cost-efficient HVAC solutions.

We look closely at the following factors before recommending the right HVAC system for your needs:

  • Heat bearing equipment and appliances installed in the room(s). This includes server units, computers, photocopiers, kitchen appliances etc.
  • Types of rooms in your commercial property such as showrooms, display floors, reception area.
  • Activities and work flow throughout these spaces

We take careful consideration of all of these factors before presenting the plan to you. Learn more about us. Schedule an appointment with us so we can help in designing the right HVAC system for you.


Air Conditioning Cooling Problems and the Role Your Thermostat Plays

Thermostat is one of the most complex components of your air conditioning system. So it is not surprising if you find yourself frustrated when it becomes the cause of your HVAC system failure.

Air Conditioning Cooling Problems and the Role Your Thermostat Plays

In today’s blog, we’ll be discussing some of the most common problems associated with your thermostat and what you can do about it.


How Does a Thermostat Malfunction Affect Your AC’s Performance

An inaccurate temperature assessment may result in your unit failing to identify whether your home has reached its desired temperature. As a result, the system may continue to struggle reaching this leading to faster wear and tear.


What are the common signs associated with a thermostat malfunction?

Here are the tell tale signs you need to go and check on your thermostat:


Inconsistent Room Temperature

If you feel cooler but your aircon is registering a different temperature, then this is a sign that your thermostat is not functioning correctly. It’s time to check if it is directly exposed to sunlight, near heat sources or cold spots.

If this is so, then it is best to relocate your thermostat to an isolated area far from these sources. Observe if the inconsistency with the room temperature remains the same. If not, then you have solved the problem. Otherwise, call a licensed AC specialist in Brisbane.


Failure to Properly Switch On and Off Your Unit

If you are manually switching on and off your unit, then it is already an indication that your thermostat has to be recalibrated. This has to be done so your HVAC will not need to work overtime. Call us on 0419 701 646.


Aircon Suddenly Shutting Down

This may be due to several factors, including wiring issues with your thermostat. So if you experience a periodic shutting down of your aircon, it is best to consult this matter with reliable aircon service and repair specialists in Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes . We will take action on this matter, immediately.


Simple To-Do Things to Help Fix Thermostat Issues

When you experience the above things with your air conditioning unit, it is best to consider the following:


Time for some thermostat cleaning

Dust and grime can build up inside your thermostat. When this happens, it can make your thermostat work inconsistently. Get an AC technician to do this for you to ensure your thermostat is clean and working efficiently. Talk to us.


Level the thermostat correctly

This is a common issue among old aircon models. So ensure your AC technician looks closely at it so it will be levelled correctly, otherwise it will not keep up the right temperature measurement.


Program defect on your thermostat

If you think thermostat issues only happen with old models, then you better think again. Although the levelling of your AC’s thermostat may not be a problem for computerised systems, a problem you need to deal with is the incorrect programming of some of these.

So, if your AC is running a smart thermostat, it is best to ask one of our AC specialists to help you with it. We are happy to help.


Improper thermostat installation

Another possible reason for a thermostat malfunction is improper installation. You’ll quickly identify if this is the case once you see loose wires on your thermostat. If you see one, avoid pulling out the thermostat on your own. Rather, call a reliable AC technician to handle this for you.



Thermostat plays an important function to the overall efficiency of your air conditioning system. Choose an experienced air conditioning expert to handle the installation, repair and maintenance of your system. Learn more about the different locations we service in Queensland.


HELP! My Air Conditioner is FROZEN!

Brisbane seldom experiences a freezing winter, but do you know that your air conditioner may suffer from one?

HELP! My Air Conditioner is FROZEN!

Yes! This may sound weird but there are many reasons why your aircon may experience this. Learn more about it in this blog.


Understanding the Joule-Thomson Effect and Its Relationship With Your AC Unit

To begin, let us first understand your AC unit functions. This is explained via the Joule-Thomson Effect.

If this process gets disrupted. The evaporator coil of your unit will allow the refrigerant to excessively cool. This allows it to fall below freezing temperature and start to develop ice all over it.


What are the Potential Causes of an Aircon Freeze?

To prevent this from happening, it is best to identify the possible causes of this scene.


Low Refrigerant Level

Your air conditioning system is designed to effectively function with a full tank of refrigerant. So when the refrigerant level drops, it not only results in an inability to cool your room; but it may also lead to a frozen system.

Now if you are thinking you can easily add refrigerant to your system, then you better think again. This is because air conditioning refrigerants are only to be handled by licensed AC technicians. This is a hazardous substance that if handled properly may result to skin burns.

So just let the experts handle the refilling of your refrigerant. Talk to us, today.


Blocked Filter

A blocked filter, mostly due to dirt build up, may also result in a frozen aircon.

It blocks the cold air from going out of the system. This cold air gets trapped inside where it builds up moisture, which leads to a frozen system. So to avoid this from happening, it is absolutely important for you to regularly clean and maintain your unit.


Faulty Thermostat

A faulty thermostat may also send false signals to your unit keeping it to cool even if it has already reached its desired temperature. When this happens, expect some parts of your unit to freeze, too.

Read here to know more about faulty thermostats and how to handle it.


Clogged Drain

Although this happens on rare occasions, this may also lead to water and moisture to get stuck inside your system. This puts your system at risk of freezing.

So do not wait for this to happen. Always have scheduled maintenance of your system, especially during change of every season.



A freezing AC system is frustrating, especially if this happens when you need it the most. However, this can be prevented with regular cleaning and maintenance. So it is important to never forget your scheduled AC maintenance.

Ensure the Look of Your Luxury Apartment with an Efficient AC System

Luxury apartment owners usually forget about the importance of comfortable and clean air. Not until their apartment’s air conditioning (AC) system starts to fail.


The consequences can be devastating and can take a toll on their savings. Why? Because their expensive decors and furnishings can be damaged when their air conditioning system fails. It’s worse than being in a hot situation for a little while and paying for an expensive repair.


So, you may ask, what do you need to do? Below are your answers.


How does a faulty air conditioning system compromise an apartment’s decor?


Some of the things that can be compromised should your apartment’s air conditioning system break down are the following:

  • Woodwork
  • Wallpaper
  • Rugs
  • Mouldings
  • Furniture
  • Artworks
  • Musical instruments


These things can be expensive, thus, it’ll be sad to imagine if they get ruined because of a failing air conditioning system. That’s why it’s important to have an efficient AC system in your luxury apartment.


Ensure the Look of Your Luxury Apartment with an Efficient AC System


What are the results of a faulty air conditioning system in a luxury apartment?

Here are just some of the things a faulty air conditioning system can do to your property in  Clontarf, Balmoral, Bribie Island, Bulimba, Green Slopes, Hawthorne, Morningside, Noosa, North Brisbane, North Lakes, Redcliffe, South Brisbane, and North Lakes.


Moisture and humidity

These two are the enemy of distinct decor and finishes. The excess moisture and humidity can cause the woodworks and mouldings to warp. These can also cause moulds in wallpaper, painting, rugs, photographs, upholstery and draperies. As a result, your luxury apartment will have a foul smell because of the mould build-up.


Humid air and water leaks

Humid air and water leaks commonly happen in apartments when their air conditioning system breaks down. This can also happen if the AC is not working for a long time. The air conditioner’s refrigerant can get low and freeze the evaporator coils, which can result in overflowing water in the drainage pan.


How do you ensure the looks of a luxury apartment with an efficient AC?

To ensure the looks of your luxury apartment perform regular air conditioning maintenance.

So, let us talk about how apartment air conditioning maintenance works and its significance to your AC and luxury apartment.



During AC maintenance, the technician inspects your unit for potential problems. This way, the problems are detected and fixed on the spot, thus, you can ensure that your air conditioning unit is in its best shape.

For example, there’s a small leak in your AC’s refrigerant. Through regular inspection of your unit, it’ll be found immediately and repaired before it causes bigger damage to your luxury apartment.



Over time, some parts of your air conditioning unit like the capacitor, wires, or fan motor will wear out. If your AC unit is regularly maintained, the AC technician can replace it before it leads the whole AC system to a breakdown, which may also cause you to replace the entire system.

This makes it an easy and inexpensive way to keep your air conditioning system efficient for you and your apartment.



During an air conditioning system maintenance, your AC technician will thoroughly clean the components of your cooling unit. If you are tempted to do this on your own, then STOP. This is definitely not a good idea because some delicate parts of your system you may accidentally break.

Thoroughly cleaning an air conditioning system requires proper knowledge and tools to accomplish. So, you must call a licensed AC technician to perform this.

Understanding the ZERL Granted to Daikin Split System Air Conditioners

In one of our previous blogs, we’ve shared the importance of checking the energy rating label of air conditioners. We’ve also explained how it helps in choosing the most economical cooling unit in the market.


But, did you know that there’s a new energy rating label and it’s granted to Daikin’s Split system air conditioners?


Yes, and it’s called Zoned Energy Rating Label (ZERL).


So, for this blog, we’ll help you understand what is ZERL given to the split system air conditioners of Daikin.


Understanding the ZERL Granted to Daikin Split System Air Conditioners

The new Zoned Energy Rating Label


Getting efficient and economical split type air conditioners has been made easier with the new ZERL.


The Zoned Energy Rating Label has divided the continent into 3 distinct climate zones: Hot, Average, and Cold. This allows the buyer to compare and identify the air conditioner that matches the climate in the zone they live in. Therefore, you can get the exact type of cooling unit for your home.


In this new rating label, the number of stars still applies. So, the more stars a split system air conditioning has, the more efficient it is.


The difference between ZERL and Old Energy Rating Label (ERL)


Now, let us dive a little deeper into the difference between the new ZERL and the old ERL.



In the old ERL, the star ratings are calculated through a single indoor and outdoor temperature condition. It doesn’t take into account the different climate conditions around Australia. Below’s a sample photo of an old Energy Rating Label.

Old Energy Rating Label - Wahoo Air Conditioning


Now, here are the performance calculation details in the old ERL.


Performance calculation details


  • The calculation counts the standby power and assumes it will be 6760 standby power in a year.
  • The calculation in the old ERL assumes that the AC will be cooling or heating 2000 hours per year. This equation doesn’t include the climate condition where the AC will be operating.
  • In ERL, they base the star ratings on the efficiency of the air conditioning unit at 7 °C (for heating) outside temperature and 35 °C for cooling.


Now, let’s understand the new Zoned Energy Rating Label in the following.



In the new ZERL, the star ratings are based on the calculation of two factors: The local climate data and the temperature profile of a zone throughout the year.

Now, the result came out as seasonal efficiency star ratings and there are 3 distinct climate zones. The Hot, Average, and Cold.

With the new ZERL, the buyer can now easily identify which split type air conditioner fits the climate zone they live in. The noise level and energy usage are also now added to the air conditioner’s specification for additional information.


New Zoned Energy Rating Label - Wahoo Air Conditioning


Here are the details of how the performance is calculated in the new ZERL.


Performance calculation details


  • To estimate the number of heating and cooling hours an AC will have, the new ZERL uses the climate data on a specific zone with a range of climate temperatures.
  • The calculation in the new ZERL considers that the time at standby and standby power is dependent on the zone.
  • In the new ZERL, the annual energy use is shown based on specific conditions.


Please bear in mind that the star ratings between ERL and ZERL can’t be compared. This is due to the different calculating methods they’ve applied.


Reading the new Zoned Energy Rating Label

Now that you know the difference between the old ERL and the new ZERL, let us now show you how to read the new Zoned Energy Rating Label.

#1 Brand and model

This is where you’ll see the brand and model number of an air conditioner. Make sure to check this carefully to ensure you’re getting the one you desire.


#2 Cooling capacity

This is the cooling capacity (kW) of the air conditioner at a 27 °C indoor temperature and 35 °C outdoor temperature.


#3 Heating capacity

This is the heating capacity of the air conditioner (kW) at a 20 °C indoor temperature and 7 °C or 2 °C outdoor temperature.


#4 Sound levels

These values show the indoor and outdoor sound level of the air conditioner. The lower number indicates the unit’s quiet operation.


#5 Star ratings

The number 5 shows the star rating of the air conditioning unit. These stars indicate the efficiency of the unit to the different climate zones. On this part, you may want to remember that more stars mean higher efficiency.


#6 Energy usage

This one tells how much energy will be used by the air conditioner in cooling or heating your home per year. The lower the kWh means the lower energy it will consume.


There you go. Hopefully, this has helped you understand how the Zoned Energy Rating Label works.
