What Is A Split Wall Air Conditioning System?

Split system air conditioners are a popular choice for Sydney residents looking for reliable heating and cooling solutions. With two separate units, an indoor and outdoor unit, hot and cool air can be efficiently directed as needed throughout your home.

Essentially, the indoor unit has an evaporator coil that cools down the room according to your set temperature. Meanwhile, the outdoor unit contains a condenser coil, which heats up outside air to be blown into the house through ducting. This is known as reverse cycle air conditioning, which is a major benefit to split systems.

Interested in installing heating and cooling functions into your Sydney home with just one system? Get in touch with the experts at Alliance Climate Control today to enquire about a split system air conditioning unit.

Check out how our dedicated team can help you today!

Locally-trained and licensed technicians are available across Sydney to install your choice of split system air conditioners. We handle all of the work, leaving you confident in the knowledge that our installation team will leave your home just the way it was, now with an added AC system.

With an on-site assessment of your home, we can recommend the best system for the household’s needs. Whether that’s an air con unit that prioritises low running costs, or one that features extensive filtering for allergy-prone occupants.

Find your best match in split system products and installation services with us.

Repairs

Have you noticed your split system air conditioner experiencing some issues during operation? Uneven cooling, leakage, loud noises, or even bad smells? These can all be signs that your system requires a professional assessment and repairs.

Without timely intervention, your system’s lifespan can be greatly reduced as HVAC issues build up. This means more costly repairs, greater electricity bills, or the need to completely replace the air conditioner

Ensure year-round comfort by scheduling an appointment with the experts over at Alliance. We have the skills and knowledge to identify any problem your split system AC may be experiencing, as well as resolve it promptly.

Replacement

When your current air conditioning unit can no longer reliably perform, even after professional repairs, it may be time for a replacement system.

Alliance handles all of the work that comes with removing an existing AC and getting a split system installed. With our expertise, we can have your home tidied and your new cooling systems operating in just one efficient appointment.

No need to break your own back by disposing of your old unit, either. We also take care of the recycling of broken-down ACs, including offering all Sydney residents access to rebate discounts. Save more time and money by bringing in the experts for your AC replacement service.

Cleaning

Keeping split-system air conditioners operating at peak performance requires more than maintenance. It also means scheduling an annual clean from HVAC specialists to remove any blockages and prevent high heat loads on crucial components.

Without a regular cleaning, issues such as coil freezes, water leakage, poor energy efficiency, and reduced airflow capacity can become apparent. That’s why Alliance provides a thorough Eco-Clean service that only uses environmentally-friendly products; we prioritise both your AC and the environment.

Maintenance

It’s highly recommended that your split system air conditioner undergo an annual check from an HVAC professional. Without regular fine tuning, small issues can build up over time, potentially leading to an inconvenient and costly breakdown.

Alliance ensures each maintenance appointment ends with our local team leaving behind more efficient systems than we entered with. This is achieved with thorough examinations of your split system air con and its components; both within the indoor and outdoor units. Then, we take care of any work required to restore your system to its peak performance.

Alliance Climate Control technicians are ready to mobilise and waiting on your call. It’s time to set up your annual appointment with a technician now!

Why Install a Split System Air Conditioner in Your Home?

Unlike most other air conditioning systems, the split system design strongly aligns itself as a heating and cooling unit, adaptable to any climate across Sydney. Otherwise known as reverse cycle split systems, this product is commonly installed by Sydney residents since it’s an all-in-one package for dealing with summer and winter.

You can easily distribute clean, comfortable air around your home or business with a split system air conditioner. However, other notable benefits of installing these reverse cycle systems include:

  • Quiet to run and less intrusive to install than ducted air con
  • It’s cheaper to install a split system air conditioner than a centralised system
  • Built-in filters help keep your air clean and pure
  • Energy-efficient operation, especially with the latest models
  • Sleek, stylish and modern designs that suit every home or office
  • Reverse cycle heating and cooling that can be zoned to specific rooms
  • The durability of the outdoor unit and the simplicity of the indoor unit make maintenance fairly easy

How Much Does A Split System Installation Cost?

Multi-Split-System-2

Generally, the cost of split system installation is low. This is because it’s less invasive than ducted air conditioning to install, and you can end up paying much less if there are fewer areas you want to cool.

However, split system installation costs vary greatly depending on the number of rooms you have and how large they are. For example, a typical three-bedroom home, with one living room and one multi-purpose room, you could be paying anywhere from $4,500 to $6,700 to place split system units in all rooms.

At Alliance Climate Control, we have technicians who specialise in split system installation. No matter where you are in Sydney or Greater Sydney, we strive to provide highly tailored and customised quotes for split systems – just give us a call to book an appointment with one of our technicians today!

Tommy, Staad, and Charles did an excellent job installing a replacement split system. Charles took time to work out the most efficient cable routing. Tommy led the team in an installation where the outdoor unit needed to be maneuvered over an outdoor cat enclosure (catio). Calls on approach and arrival on time helped us too.

I’m pretty satisfied with the project from the beginning to the end! The installation team wit Ivan, Maisan and Mosa were very efficient and punctual! After completing their work they cleaned and removed all the debris and vacuumed! I was quite pleased and hopefully the new system will work perfectly, as I have not used it since the installation as there is no need due to the weather conditions. Ivan gave me the tour and clearly explained how to operate it! Thank you 🙏

All members of the Alliance team I dealt with were knowledgeable, respectful, and friendly. During both the inspection and the follow-up visit to complete the work, they took great care to respect our home and carried out the job professionally, leaving everything clean and tidy. The entire process went smoothly, and the price was fair considering the high quality of the service provided. Their excellent customer service stood out, and I would happily recommend then to my family and friends.

⭐⭐⭐⭐⭐ Outstanding Service from Alliance Climate Control! I honestly couldn’t be happier with the service I received from Alliance Climate Control. From the very first time I reached out for a quote, the entire experience has been nothing short of excellent. The communication and professionalism from the team were fantastic from day one. Harry, who came out to provide the quote, was extremely professional, knowledgeable and easy to deal with. On top of that, their pricing was by far the best I received — making the decision to go with Alliance an easy one. I also had Kody come out to look at another request I had, and once again, the service was exceptional. Darra, the installation engineer, did an outstanding job. He was professional, thorough and clearly took pride in his work. And the service didn’t stop once the installation was completed. James followed up afterwards to make sure everything was going well. That level of after-sales service really says a lot about the company. I genuinely cannot find anything to fault. Every person I dealt with was friendly, professional, knowledgeable and genuinely committed to providing great service. Alliance Climate Control really are the complete package — great people, great service, great workmanship and great pricing. I’ll definitely be using them again in the future. They can have my money any day! 😂 If you’re looking for an air conditioning company, I highly recommend Alliance Climate Control. You won’t be disappointed. 10/10 service from start to finish! 👏👏👏

Frequently Asked Questions

Each HVAC brand brings unique benefits and features to your home through split system ACs. So, the perfect choice for you may differ greatly to another resident due to your different lifestyles and household needs.

However, Alliance partners with some of the most reliable brands in the Australian market to efficiently power your climate needs. This includes well-known brands such as Mitsubishi Electric, Daikin, Fujitsu, and many more.

Installation of any HVAC system, including split system air conditioners, generally doesn’t require a plumber. Rather, a HVAC specialist like those at Alliance are needed for a professional and reliable install.

The answer as to which is cheaper is entirely dependent on what type of Australian home each system is trying to cool or heat.

For example, ducted air conditioning systems are generally used for larger homes, hence usually costing more than split systems. However, running a multi-head split system may cost just as much or more if used for several rooms.

Discuss which may be the more cost-effective option for you with Alliance.

For some Australians, the following factors may be considered a disadvantage of split system air conditioners:

  • The need to install an outdoor unit and then multiple potential indoor units where airflow is desired
  • More complex installation processes than some other air conditioning systems
  • Indoor units are often more visually obvious than ducted systems
  • Limited operations in larger-scaled rooms or an open space
  • If the outdoor unit experiences a problem, all internal functions will also stop
