Does Home Aircon Need Regassing?

In this article, we seek to address your air conditioning needs on the topic of air conditioning regassing!

However, you should always seek the help of an air conditioning systems professional to speak about your specific conditioning needs.

Together, you can best determine the cause of disruption to your conditioning systems.

What is an air conditioning regas?

An aircon regas is the process of removing old refrigerant gas from the existing system and then replacing it with new refrigerant; this ensures that your aircon will run cold again.

There are several signs to look out for in your air conditioning unit that may suggest a need for a re-gassing.

How often does an air conditioner need re-gassing?

It is rare that your air conditioning unit should need regassing.

If an air conditioner does need re-gassing- it is likely a sign that your system has not been installed correctly or it could be a manufacturing fault.

The quality of your home air is essential to enjoying your home, it is good to be cautious and keep an eye out for any signs that your air conditioner needs a re-gas.

If you hear any bubbling or hissing you should immediately turn your system off and contact your local air conditioning services (there are many various services throughout Australia) who will then send air conditioning technicians to help you.

Signs that your air conditioning unit needs re-gassing?

One sign that is indicative of a problem with your air conditioners (and in turn potentially affecting your home air) is the presence of icy piping.

Icy piping suggests that your conditioner system runs with such low amounts of refrigerant that the system itself has frozen.

Another symptom that suggests that your system needs a re-gas is if your air conditioners seem to be expelling warm air conditioning- despite being on for long periods.

New noises coming from your household appliances are often a cause for concern- and your air conditioning is no exception.

Noises are a serious matter, and it is time to call in the experts if this is happening!

Why does my air conditioner need a regas?

You may be wondering why your air conditioning systems require a re-gas, there are several possible reasons that your system needs a re-gas, we will explain the top causes below.

However, you should always seek the help of an air conditioning systems professional to speak about your specific conditioning needs. Together, you can best determine the cause of disruption to your conditioning systems.

Manufacturer’s faults

One common reason that systems need re-gassing is a fault with manufacturing.

Poor manufacturing occurs more often with cheaply manufactured systems. However, it can happen with more quality brands also.

Poor installation

Another problem which may require a re-gas is the simple matter of poor installation. When installing your air conditioning unit, the air conditioning company will send somebody to install the unit.

It is also essential that pipework is cut correctly, this means ensuring that it is d-burred, flared, lubed and torqued, as without this a gas leak may well develop. Pipe connections are vital here.

Finally, service caps are used to reduce refrigerant leaks on the service valves on your air conditioner. It is essential that these aspects are suitably installed, or they will gradually loosen in the refrigerant.

The refrigerant is what keeps the air conditioning cold; therefore, a refrigerant leak is detrimental.

Wear and tear

There is the possibility that over years of usage and general wear and tear your air conditioner could well become susceptible to damage. Although this is a gradual process, it may require a reinstallation should it become too damaged.

Why not schedule maintenance check-up? This way, you can have peace of mind and rest assured that your air-con performs to the best of its ability.

Whilst these prospects may sound daunting, you can make sure to limit the chances of them happening by selecting a well qualified and experienced professional to install your air conditioner!

How much does an air-con regas cost?

There is no way to determine how much your specific air conditioning work would cost- as this is entirely dependant on the mechanic or other factors such as whether you require a straightforward re-gas or a full re-installation.

However, should your system need servicing, this money is well worth its while, as it could prevent further costs from incurring in the future!

How to find an air conditioning technician

To find a trustworthy technician, we recommend that you look online to find one near you.

Through online research, you can also assess their credentials and qualifications and ensure that their work is quality.

After all, as mentioned previously, a good air conditioning service is imperative to your system’s longevity!


Here are some frequently asked AC questions:

Can I regas air conditioners myself?

There are kits available should you wish to attempt to fix your air conditioners yourself. However, we highly advise against this.

It is imperative that this is done to a high standard, and you may create further problems without the knowledge necessary to do so correctly.

What is a split-system regas?

A split-system regas is the regassing of a split system air con unit. For example, a wall split system unit.

A wall split system air conditioner has four connection points, two internally facing and two parts outdoors.

If your aircon receives improper welding, then small leaks may well develop, meaning that your aircon will become susceptible to breaking down and requiring increasingly more gas over time.

A professional can advise you on your specific issue.

Does an air conditioning system need regular maintenance?

If your aircon has been installed well and is of a good standard, it should not need frequent regassing.

However, as with all household appliances, it will benefit from a regular professional check-up to ensure that all is well. Get in touch with our Brisbane based air conditioning servicing team for more information on this.

Do Air Conditioners Need Servicing?

If you’re a native Aussie or you’ve lived down under for a while, you’ll know how scorching summer in Australia can be. While most of the world is whacking the heating on, you’ll be turning to your air conditioner to save the day!

For this reason, your home air-con system must be working perfectly. You may not realise, but your AC unit should have regular servicing to keep it in tip-top condition.

In this blog, you’ll find lots of useful information and tips about maintaining air conditioners. But first, let’s look at how often they should be serviced.

How often does an air conditioning system need servicing?

Many air conditioning experts recommend you have yours serviced at least once a year. This is especially important if you don’t use it all year round.

If your air conditioner’s been sitting twiddling its thumbs throughout the winter months collecting dust, you can guarantee it’ll need a pre-summer freshen up.

It’s advisable to book your annual service around the same time every year so you know when it was last done.

Another tip is to plan your air conditioning service a couple of months before the hot weather usually makes an appearance. This ensures you’re not left without it during sweltering temperatures.

Signs that your air conditioner needs a service

You want your AC unit to be in full working order, but how do you know if it requires some TLC? These are a few warning signs to look out for:

  • Blowing out warm air instead of cool air
  • Reduced efficiency and poor airflow
  • Leaks
  • Unpleasant odours
  • Inability to keep moisture levels low

While you may be tempted to perform DIY repairs, it’s best to contact a professional. An air conditioning unit is a complex system and any DIY attempts could end in disaster! Our qualified technicians will have your system up and running again in no time.

How do I service my air conditioner?

Do it yourself

Something many home air conditioning owners ask is whether they should attempt DIY servicing or not? When it comes to actually servicing your air conditioner, always enlist the help of a qualified technician.

However, you can do a bit of basic cleaning and regular maintenance yourself. You can do small tasks such as cleaning or replacing the filter and maintaining the unit’s housing.

These are great ways of keeping your air conditioner in good shape and you may not need to have it professionally serviced as often.

However, deep cleaning the unit may not be easy to do on your own, so it’s always better to contact a professional team!

Hire a professional

If your air conditioner needs more than just routine maintenance, make sure you call an expert technician. A specially trained expert will be able to diagnose the issue with your air conditioner and find a solution.

They should check for things such as:

  • The airflow through the evaporator coil
  • Any duct leakages in the central systems
  • That the thermostat is accurate
  • The cooling system and heating system aren’t working simultaneously
  • Collect any refrigerant that needs to be taken out of the system, rather than releasing it into the environment, which is illegal.

Remember, your air conditioner is an intricate machine and anything other than general cleaning or maintenance should only be carried out by a professional!

Air conditioner parts that need to be maintained


The filter is one of the most essential parts of your air conditioner unit. Regular maintenance is essential for it to work effectively and efficiently.

A dirty, clogged filter will block the airflow and prevent the unit from functioning correctly. If the airflow is restricted, any air that passes through the filter may carry grime, dirt and other nasties into the coils and impair them.

Changing the dirty filter with a new, clean one can reduce your home air conditioning unit’s energy usage by up to 15%.


The evaporator coil and the condenser coil can both accumulate dirt after months of use. Clean filters make sure the evaporator coil doesn’t become dirty too quickly. However, over time the coil will soil anyway.

This build-up of dirt and grime blocks the airflow, meaning the coil won’t be able to absorb the heat. To prevent this problem, give the evaporator coil a clean every year and check it regularly.


The evaporator and condenser coils have aluminium fins. These fins can be bent easily and in turn, block the airflow through the coils.

You may need to buy a fin comb. These combs will help push the fins back to their (almost) original position.


It’s a good idea to occasionally poke a stiff wire into your air conditioner’s drains. Blocked drains stop the unit from reducing the humidity levels.

Because of this, you may end up with discoloured carpets or walls because of the excess moisture.

Air conditioner FAQs

What happens if AC is not serviced?

Once you’ve had your air conditioner unit installed, it can be tempting to just leave it to its own devices and not bother servicing it. However, like other technical gadgets, an air-con system also needs regular upkeep.

If you don’t, it could result in costly repair bills or worse, the air conditioner will break down completely. The last thing you want is summer in Australia without a functioning air conditioning system!

Do central air conditioners need to be serviced?

Yes! If you want to have a fully functioning air conditioner and save money on repair bills, servicing your unit is essential.

Dirty air filters, poor energy efficiency and low air quality are just a few things that can happen if it isn’t serviced regularly.

Maintaining yours through the winter will also help to keep it in good condition. Over the cold months, cover your home unit or remove it completely and put it into storage. You can also cover the outdoor unit to protect it from debris and harmful winter weather.

Air Conditioner Installation Cost Explained

Planning to purchase an air conditioning system, but overwhelmed by the many options you have? You know, if choosing between ducted air conditioning and a split system was a black and white matter, we’d give you a straight answer. But it’s far more complicated than that.

In this article, we will discuss what makes ducted and split systems different from each other so you can make an informed decision before you make any purchase. The differences between them may not be particularly apparent, but you’ll discover some key differences when you scratch beneath the surface.

Before we discuss the pros and cons of each type, let’s first define what these two air con systems are:

Ducted AC and Split AC in a Nutshell

As its name suggests, the ducted type works by using ductwork in the walls and ceilings of your home. Don’t look anywhere for the main unit of this air con system because, unlike the split type, its condenser is typically out of sight.

That’s one of the major differences between the ducted and split systems. With a split air con system, the condenser, which serves as the outdoor unit, is usually outside the home. This air conditioner applies pressure to the refrigerant, which then runs through tubing that’s connected to the indoor unit, known as the evaporator.

Now, let’s compare them based on the factors that make them distinct from each other.

Ducted vs Split System: Key Differences


When choosing an air con, what matters is the size of the space you need to cool. If the space is small, you can go for a split air conditioning system. Or, if there’s one room that’s been added onto your home, but can’t tie into your existing system because its location doesn’t allow it, a split system should, again, be your first choice. If you are living in a two-storey apartment, you can’t choose the ducted type since installing ducting between levels is impossible.

The good thing about ducted systems, however, is that they can cool a space as big as your home. You can even have this air con type zoned to cool only certain rooms in your home! The result of this would be energy efficiency and cost effectiveness. If you’re just building a new home, or retrofitting your home, this type of air conditioning would work since you may include the space required for ducting in your design plans.


Since the split air conditioning system is designed to cool individual rooms and not your entire home, you will find that even when you install several air conditioners in every room, the multiple units would still not be enough to uniformly cool your house’s interior. And since additional units mean additional power consumption, at some point there would be reduced returns in terms of energy efficiency.

When it comes to ducted systems, you’ve probably heard critics cite leaks between ducts as one of the reasons these air cons are inefficient. Actually, you can avoid this by making sure your unit is installed only by a professional. Moreover, ducted air cons can still provide air conditioning within your house. If there’s one thing that makes ducted air conditioners inefficient, it’s how they cool your entire home even when you are only using a portion of your home.


Have you ever experienced hearing a loud buzzing noise coming from an air conditioning unit? That is one of the common problems associated with air cons, and we bet you don’t want yours to be like that. Usually, the noise coming from an air conditioner is the compressor expanding and reducing pressure during the heat transfer process. Sometimes, it’s a result of loose parts, some debris or faulty blades. Fortunately, both ducted air conditioning and split systems are quiet types of air conditioners. Since the condenser of a split air conditioner system is located outside your home, you don’t hear any noise coming from its condenser. Just the same, the attic of your home absorbs much of the sound produced by your ducted air con.


You can’t look past convenience and flexibility when shopping for an air con. Luckily, both the split type and ducted type offer a good deal of both. For instance, a split system unit is more flexible in terms of how you install it, since you can simply mount it on the wall or ceiling of your home. This air conditioner is also programmable, very easy to operate and comes with remote control options for convenience. Meanwhile, a ducted air conditioner also requires little effort to operate once installed. You control it via panels at various locations in your home. You can even find brands that offer remote access to your ducted system via a phone app! How cool is that?


Yes, you read that right. Aesthetics also matters, even for air conditioners! If this factor is important to you, we suggest that you go for ducted systems. With only its vents showing in each room, you’ll find that ducted systems are virtually invisible in your home. On the other hand, you may find that despite its trim profile, a split system tends to look obtrusive because of its evaporator. Although this type of air con varies in size, you may find that even its smallest unit is still visibly apparent. Even if its outdoor condenser is positioned to blend with your landscaping, you may need some additional shrubs to make sure you achieve your desired aesthetics outside your home.


We understand that budget is one of your most important considerations when buying an air con, so let’s talk about the cost of installing each type. Several factors contribute to the cost of installing air conditioning, including the size of the space to be air conditioned, the size of the unit, comfort level, and so on. Generally speaking, however, split system air conditioners are much cheaper than their ducted counterparts. For a single installation, a split system can start in the range of $2,000, while a ducted system will start at around $10,000. Take note though that while the split system looks like the obvious winner here, you should also balance their initial costs with your long-term goals. For example, when it’s time to sell your home, your split system may not be as appealing to homebuyers, but the aesthetics and utility of a ducted system will definitely make this type a huge plus to your home.

Ducted Air Conditioning vs Split System Air Con: Which is the Better Choice?

Still undecided which, between the two types of air conditioners, to buy? Truth is, there is no one-size-fits-all answer as to which air conditioning type is the best. As you make your choice, consider your needs and your budget, and what you are looking for in terms of cooling.

While the initial purchase and installation cost of a split air con system is much less than having to install ducted air conditioners, it could be beneficial for you if budget is your driving force.

Meanwhile, a ducted air conditioning system costs more than the other, but it operates more efficiently. If you plan to stay in your home for a long time, you may consider this option because it is more cost effective in the long run, and can also add value to the selling price of your property.
