Multi-Split System Air Conditioning – Flexible Comfort for Multiple Rooms

Need an efficient solution to cool or heat multiple rooms independently, without the complexity of ductwork?
A Multi-Split Air Conditioning System might be the perfect fit. At Alpha & Omega, we specialise in the design and installation of Daikin multi-split systems across the Sutherland Shire, St George Area, Eastern Suburbs, Sydney CBD, and Lower North Shore.

✅ What Is a Multi-Split System?

A multi-split system uses one outdoor compressor connected to up to nine indoor units, allowing you to control each room individually. This delivers:

✔ Personalised comfort in every space
✔ Reduced energy consumption
✔ No airflow wastage like in ducted systems
✔ Easy zoning with independent temperature control for each room

🌬️ Cleaner, Healthier Air

Compared to ducted systems, multi-split units offer superior air quality control—ideal for asthma sufferers or those with allergies. Each indoor unit works independently, helping to reduce the spread of dust, allergens, and pollutants.

📏 System Capacities & Room Customization

Our expert team will design your system based on:

🔹 Room size and environment
🔹 Desired usage patterns (e.g. living areas vs bedrooms)
🔹 Aesthetic and layout preferences
🔹 Air quality and ventilation needs

Indoor Unit Capacity: 2.2kW to 5.0kW
Outdoor Unit Capacity: 6.5kW to 14.0kW

We work closely with you to select the ideal combination of indoor units and match them with the appropriate outdoor unit to ensure maximum efficiency and comfort.

Went with local company Alpha & Omega for wifi accessible ducted a/c. Their recommendations were greatly appreciated (and competitively priced). Service was fast and professional. Everyone I dealt with was excellent. From Danielle in the office to on-site visits from Daniel and Nigel. Highly recommend.

If you are in the Shire and need your aircon unit serviced or repaired I cannot rate these guys highly enough. Many thanks to the team. They were the first aircon repair centre to pick up the phone during peak season. Transparent on price and work that was to be completed. Though the reason for my failing aircon was a simple part, the peace of mind that they could get it diagnosed and repaired in a reasonable time left me a satisfied customer

In my un-bias opinion, this business is the BEST Air Conditioning business in all of NSW, no- Australia, wow I have tried so many Air Conditioning places across the length of my life, and nothing has EVER compared to this easily reachable, friendly, affordable company. I wish I could know the owners/founders and thank them, their Air conditioning has now been in my house working more than perfectly for over 10 years. So easy to clean, and the installation process is so easy. If I could buy more air conditioning for my already cool but yet mellow house, I would! Thanks, Alpha & Omega! Definitely recommend!

Alpha installed for us in our new place 5 years ago. We used them based on past experience over 30 years. Have always found them to be organised, punctual, and efficient. Rodney was polite and knowledgeable.

I'm very pleased with the thorough service Alpha's technician carried out on our Daikin ducted system. Jim (technician) also fixed the torn air conditioning filter that our dog had broken. I can highly recommend this company

Nigel, Joel and the team did a great job at retro-fitting what I would call a quirky house, and offering solutions to best fit each room. It is so lovely to come home to a warm house in the middle of winter. Thanks team!

I've use Alpha & Omega a couple of times to service my Daikin ducted airconditioner. I found them easy to deal with, reasonable pricing, prompt for appointments and good at their work. I will definitely continue to use them in the future.

My Air conditioning system suffered electrical damage and I entrusted Alpha and Omega to install a new 3 phase Daikin system with the I-zone option. I took Glenn's advice and the Daikin I-zone combination is simply amazing. The team performed a fantastic install at my clinic and the staff all love our new system. The I-zone is a stand-out feature. Thanks team, Jon

Excellent service! From quote to instillation, they made the whole process easy. All staff were extremely professional and they did a fantastic job installing our two split system units neatly and in a timely manner. I would have no hesitation in recommending this company. Thanks Alpha & Omega Team!

The staff were very prompt and professional in getting me a quote. Once the job was agreed and started they worked hard to make sure it delivered as promised. True proof comes when you do have issues in how they treat this and Alpha and Omega worked hard to resolve any concerns with the system. Up and running happily.Note: With Alpha and Omega we have introduced a custom solution to bring outside air into the AC ducting system, filtered, for a reasonable price.

No hesitation to recommend this company, family owned business for over 30 years so that says a great deal. Their responsiveness is great and actually take the lead in the comms. They turn up when they say they will turn up. Their professionalism and knowledge, courteous and polite staff is appreciated, very happy with their work and def will reuse them.

Apha & Omega were great with their service from the first phone call for a quote to the completion of the installation. I would have no problem with recommending them to anyone.

We had a ducted system installed at our home last week. The team were very professional, explained all details thoroughly and even cleaned up and vacuumed before leaving. Thank you to the whole Alpha & Omega team. Very happy to recommend!

I am very happy with the service and team from Alpha & Omega. From inspection to estimate to installation they were professional, timely and friendly. I am also delighted that I followed their recommendation to switch to the "iZone" (a WiFi-controlled room-zoning system) at the same time as they added the lower floor to our built-in AC system in our home. While I tend to prefer working with local businesses, this one I can highly recommend.

Well, we got machine installed last week, all the service is good. But last Friday, only two days after that, we got a flyer in the mailbox said if get installed by 30th Sep 2019, we can get FREE wifi system. So I rang the company, they said I can't get, as the promotion is just start. But for my personal feeling, it is bad as this promotion just happened two days after I got the air condition. At least they should tell me they will have promotion soon.

Nigel & his team were wonderful to deal with. Nigel's advice was clear & proved to be exactly what we needed. Jacob's install was done with care & respect for our home. The little things that tradies usually shortcut, Jacob didn't.

I have no hesitation in recommending this company. Their quote was competitive and Glen was thorough in calculating the best outcome for us. They were punctual right through the process. Trades were professional and did their best to use drop sheets and cleaned up well when the job was finished. We are very happy with the end result.

Brilliant is all I can say.No issues, Great follow up after the install. We were hardly ever there during the install, but they kept us informed on the progress.So, trustworthy, Professional and reliable so far.

The team from Alpha & Omega AC were tremendous. From the first call to request a quote, first on site visit, listening to my requirements, providing thoughtful options and the installation from the AC technicians was exemplary. The install was 3 days and the technicians turned up when they said they would, were extremely courteous and professional during the installation, worked efficiently and productively to get the job done. At the end of each day's install they removed all rubbish from my property and keep the place clean and tidy. I couldn't be happier with the result. Thank you very much to the entire team at Alpha & Omega AC. I will certainly be recommending you to any friends/family should they be looking for any AC needs.

We were very happy with Alpha & Omega Air Conditioning. They were competitive and provided a great level of service. All staff were friendly and obliging. We were particular impressed with Joel and his team. They were very experienced with installation and even came up with creative suggestions for placement of the air vents and return.
