Pro’s & Con’s of a Multi Head AC Installation

Multi Head AC Installation Sydney

There are many great reasons to consider a multi head AC installation.

The major advantages of using a multi head AC to heat and cool your home are:

1. Flexibility and Convenience
A multi-head split system air conditioner allows you to have different air conditioners in each room that are all powered by one outdoor unit. This means you can choose a bigger unit for bigger rooms, and a smaller one for bedrooms, so everyone stays comfortable. Having different head unit combinations to choose from is also advantageous.

2. Individual Temperature Control for Each Room
Multi-split systems allow you to control the temperature in each room of your home separately, so you can save money on your electricity bill by only cooling the rooms you need.

3. Keep Exterior Clutter-Free and Space Savings
Multi-head AC systems are a great option for homes and apartments that need air conditioning. They require just one outdoor unit to power multiple indoor air conditioning units, saving space and keeping the exterior of the home looking neat. They are also great for apartments, as one outdoor unit on the balcony can provide cooling for all the rooms.

4. Quiet
Multi head AC units are a great choice for bedrooms because they are quiet and you can choose smaller hate units, which will ensure you get a peaceful nights sleep.

5. Energy Efficiency
Multi-AC head units allow you to individually heat or cool different rooms in your home, while saving energy and reducing running costs. Each unit has a thermostat that will adjust the air conditioners output based off the room temperature. It will ramp down when the desired temperature is reached and ramp up to maintain temperature, which will help save energy.

6. Affordable
Air conditioners are a great way to cool your home. They are usually cheaper than ducted systems to purchase and install, and have affordable maintenance, service, repairs, and replacement head units.

Some of the disadvantages of using a multi head AC are:

1. Placement Restrictions
Multi head AC units need to be placed on an external wall so that interconnecting piping services can run on the exterior of the building. When this is not possible, internal trunking must be used, which is not as visually pleasing.

2. Floor Plan and Interconnecting Service Challenges
For rooms on the other side of the house from the outdoor unit, the services need to go all the way around the exterior of the house, go through the house in internal trunking, or go up and over through a ceiling cavity, adding complexity and costs to the installation.

3. Noise
For complex installations, such as an up-and-over, a wastewater pump may be required, creating additional noise and costs for the installation.

4. Larger Outdoor Units
The outdoor units are larger than a single split system and unsightly. However, often the placement of the outdoor unit is determined by the design of your home, leaving you with few options.

5. Domino Effect
If one part of the outdoor unit isn’t working, it will affect all the other parts too.

6. Energy Consumption
A multi split air conditioner uses more energy than a single-split system, so it is important to get the correct size for each room in order to save energy.

Ready Electrical & Air Conditioning were excellent. They were professional, punctual, and responded quickly when I had an issue with my aircon. The repair was done efficiently and without any hassle. It’s made a big difference—finally able to sleep properly in this heat. I’d be happy to use their services again.

Troy, Khye and Danny came to install a bunch of pendant lights and a ceiling fan for us today. They were great people, very professional and the job was done perfectly. They provided sound advice on the care and usage of the units they installed. The price was competitive and we couldn't be happier with their work. Absolutely recommended.

I use Greg & his team for my client projects as an interior designer and they are always excellent. Today I had Renzo from the Ready team out to our home to service our split system. A+ service! Renzo was on time, polite, tidy & efficient. He communicated clearly what he was going to do & then confirmed when it was completed. Highly recommend!Update … I’ve now had Troy the electrician out to do…
