Split System Air Conditioning

Split systems are the most popular choice for Air conditioning installation Melbourne homes. They have one indoor unit and one outdoor unit—hence “split.” You mount the indoor part on a wall, so you pick the perfect spot for cooling or heating in any room. Most split systems now run in both cooling and heating modes.

Multi Head & Multi Split Systems

Multi head units let you run three or four indoor units from one outdoor compressor. This setup is ideal if you need to cool several rooms. With Air conditioning installation in Melbourne, you get flexible comfort across your house without extra outdoor units.

Ducted Cooling Air Conditioning

Ducted systems are larger than split units and can cool an entire home. The outdoor unit sits outside, and the indoor part hides in your roof or under the floor. Vents in each room deliver air. Your thermostat controls all modes—cooling, heating, fan—and zones so you pick which rooms to cool. This zoned control saves energy and means you can tailor comfort room by room.

Hear What Our Happy Clients Say About Us…

Just had some electrical work/ security camera set up done by Ethan, and I honestly couldn’t be happier. He was super efficient, really patient, and just overall great to work with. You can tell he knows his stuff and actually cares about doing a good job. What really stood out was the customer service — so friendly and easy to talk to. He took the time to explain what he was doing and made sure I was comfortable with everything. No rush, no pressure, just really solid work.

P.S  my dogs loved him

Anna - Kilsyth

Ethan fitted me into his schedule at short notice after we had an electrical fault emergency. Ethan was very knowledgeable and future safety was top of his list. He identified the issue immediately and fixed the damage it had caused and tested my appliance which put my mind at ease after quite a frightening experience. 5 stars, my go to electrician from now on

Debbie - Croydon

Had a great experience with Thomas Group Electrical. They were punctual, professional, and easy to deal with from the moment they arrived. They replaced a few outlets and carried out a full check of all the smoke alarms and sockets. The work was done efficiently, to a high standard, and they left everything neat and tidy. It’s reassuring to have tradespeople who are both reliable and respectful. I’d happily recommend them to anyone needing quality electrical work.

Angus - Mornington

Fast, friendly, and zero fuss. Ethan spotted an overloaded circuit I’d been ignoring for years and fixed it on the spot. Plus the bonus surge protector gives real peace of mind—no more worrying about storms frying my gear!

Melissa - Cheltenham

Ethan was incredibly thorough with our safety inspection—every circuit, outlet, and switch was checked from top to bottom. He installed the surge protection device in under an hour, and our home hasn’t tripped once since. Highly recommend Ethan’s service!

James - Brunswick

Evaporative Cooling

Evaporative coolers use water to chill air sent through ducts. They are smaller than full ducted units and cost less to run. A wet pad and fan pull in outside air, cool it, then push it through vents. With a proper installation, they work best in dry months and add fresh airflow to your home.

Cassette Air Conditioners

 Cassette units function like splits but sit in the ceiling. They blow air out four ways for even coverage. This makes them a neat choice when wall space is tight. cassette systems blend into drop ceilings and keep walls free

Legal Requirements: Isolator Installation

Every installation must include an isolator next to the outdoor unit. It meets AS 3000:2007 rules and lets a technician cut power for safe servicing. Your isolator is a small switch box near the condensing unit.
