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! 👏👏👏

What Type Of Air Conditioner Is Best For Me?

There are plenty of choices for air con installation in Sydney to keep you and your family comfortable year-round. There are some fantastic options on the market for reverse-cycle ducted air conditioning systems, keeping you cool in the summer and warm through winter.

The right system for you all comes down to your personal preferences and what you need from an air-con system. When you speak to the air conditioning specialists at Alliance Climate Control for a quote or installation, here are some questions to keep in mind.

Want energy efficient air con that is cost-effective long term?

It’s important to be aware of all the benefits and functions of the air conditioning system you are installing because installation costs can be very different from the cost to run. Some systems may come with a higher initial investment cost but cost less to run and save you money over time. Air conditioners that are cheaper to install might cost more over time through running costs.

How many rooms need cooling in your home?

The number of rooms that need air conditioning will be one of the single biggest factors influencing what system you install. The size of those rooms, their capacity and how efficient the airflow in that room needs to be will also end up affecting your decision. The more rooms that need air conditioning, the more options become available to you for large scale systems that are both energy and financially efficient, albeit with a higher initial investment.

What is the size of the area that needs cooling?

It’s not uncommon for smaller systems to be installed in Sydney homes to avoid higher initial costs for air conditioning installation. However, a system too small for the house it’s installed in will quickly be overworked and result in more frequent breakdowns. Like most things, having the correct sized system for your the is key to ensuring it runs effectively, with as few issues as possible.

Do you or your family suffer from allergies, asthma or other respiratory issues?

When your air conditioning system affects so much of the air you breathe in your home, it’s vital to choose an air conditioner with a proper filtration system. It’s especially important for your system to deliver clean, pollutant-free air for people with any sort of respiratory illness. For your convenience, here at Alliance Climate Control, we provide and install a range of allergy-friendly air conditioning with filters rated to capture up to 90% of particles and irritants found in the air.

Split System Air Conditioning Installation

Split system air conditioning is the standard type of air cooling that many homes have. The split system is made up of two components, the indoor cooling unit and the exterior heat exchanger.

The exchanger sits outside the home, dispersing the heat evenly to not interfere with plants or affect people and animals. The indoor cooling unit is what most people imagine when they think of air conditioning, a cooling unit that can be easily changed via the remote.

Split cycle air conditions have many benefits as a method of home temperature regulation. Split system air conditioners are quiet and cost little to operate. Due to the grilles that circulate the air, split system air conditioners can direct and send air anywhere in the room much easier.

Many modern models have remotes that act as a focal point for the air conditioner, focusing air wherever the remote was activated for better accuracy than manually adjusting the grilles.

Ducted Air Conditioning Installation

Ducted air conditioning is a luxurious way to cool your entire home. Installed in the roof, ducted air conditioning features tubes that disperse cool air from a central location through the tubes to vents in each room that sit seamlessly on the roof of various rooms.

The ability to zone ducted air conditioning is the biggest appeal for many customers. Ducted air conditioning zoning allows you to group groups of rooms to cool them without cooling the rest of the home.

For example, grouping bedrooms separately from the rest of the home lets you keep bedrooms cool in summer overnight while people use them without cooling the rest of the house. With the ability to pick and choose which zones are cooled at any time, you cut down on your power bill by no longer regulating rooms that aren’t in use. 

Custom Air Conditioning Installation

Here at Alliance Climate Control, we offer a range of air conditioning solutions for custom and variable-sized locations where more traditional styles of air conditioning are less efficient.

Multi-split air conditioning, for example, is a great way of air conditioning homes with multiple floors, office complexes and multi-level buildings. This type of system is often the right choice due to its ability to match the needs of its environment.

If some rooms need drastically different temperatures, it’s able to adjust without compromising on energy efficiency.

We also have a range of Variable Refrigerant Volume (VRV) units available. These systems are the best choice for institutions with more significant amounts of people, for places like hotel lobbies, hospitals and convention centres.

A VRV system differs from other systems because it works based on the size of the room that needs to be cooled. The system consists of an indoor and outdoor unit that work together to provide a consistent room temperature that is achieved more quickly, using less energy, than other systems.

Frequently Asked Questions

There is no such thing as the “best air conditioning system.” Air conditioners aren’t a one-size-fits-all solution because every home, budget, and location is unique. Contacting our team at Alliance Climate Control is the simplest way to determine the best system for your home and situation. We can calculate your heat load, inspect your space, and conduct an efficiency study to recommend the best system for you.

Your budget, the size of your home, and the number of rooms you want to cool all influence the best air conditioning system for your home. You’ll also need to pick an air conditioner brand, each with its own set of advantages and disadvantages. You can always contact our team at Alliance Climate Control to help you with this process. Our knowledgeable staff will assess your home and make recommendations for a system that will work for you.

To ensure that your air conditioning system functions properly, you should have it serviced regularly. Cleaning the air filter alone won’t be enough. An air conditioner, like any other machine, requires routine maintenance to ensure that it operates properly, efficiently, and safely. A minimum of one service per year will significantly extend the system’s lifespan and reduce the number of breakdowns you’ll have to deal with.

When it comes to determining what air conditioner you need, the size of your home isn’t the only factor to consider. Direct sunlight, roof height, machines, and residents all contribute to the ambient heat in your home, affecting how hard your air conditioner must work to keep your home cool. Our knowledgeable staff can perform a heat load calculation to determine which air conditioner will fit into your budget while not racking up a large monthly bill.

We are happy to offer an aftercare service to all of our customers at Alliance Climate Control. Our aftercare service includes the yearly maintenance that your system requires to keep it running at its best for as long as possible.
