Split System Air Conditioning

Split system air conditioners have an indoor unit and an outdoor unit—hence the “split.” They are quiet, energy efficient, and easy to fit since no ducts are needed. You mount the indoor unit high on a wall anywhere you choose. Modern split systems offer reverse-cycle heating and cooling, so you stay cozy in winter and cool in summer. For top-quality split system setup, Thomas Group Electrical supplies Daikin, Mitsubishi, and other leading brands.

Multi-Head & Multi-Split Systems

Multi-head systems let one outdoor compressor run up to four indoor heads. This suits homes that need cooling in several rooms. You pick each indoor unit’s style and place it where you need comfort most. With a professional split AC installation, you get a neat setup without extra outdoor units cluttering your yard. Each room gains its own temperature control for tailored comfort.

Key Steps in Installation

  • Site Survey: We measure rooms and pick indoor and outdoor spots for best airflow.

  • Mounting Bracket: We drill and install the indoor unit’s metal plate.

  • Piping & Wiring: We run refrigerant lines, a drain tube, and electrical cable through a neat hole.

  • Outdoor Fit: We level and secure the outdoor unit for proper drainage and venting.

  • Vacuum & Charge: We remove air from pipes, then add refrigerant to factory specs.

  • Test & Seal: We power up, test cooling and heating, then seal the wall hole and tidy up.

Every split system job follows local codes and safety rules.

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!

Benefits of Split System Air Conditioning

Melbourne’s weather swings fast. Split systems with inverter tech adjust compressor speed on the fly. This means quick heating or cooling and lower energy bills. They remove humidity, filter dust and pollen, and improve air quality—ideal for allergy sufferers. You get efficient comfort, whisper-quiet operation (<40 dB), and no bulky ductwork. Choosing our ductless air conditioning service pays off in year-round savings and healthy indoor air.

Inverter Technology Explained

 

Inverter systems ramp motor speed up or down instead of switching off. This saves up to 60% of power by avoiding constant start-stop cycles. That means lower peaks on your power bill during hot or cold days.

Keeping filters clean is simple. Slide out the indoor filter monthly and rinse it under warm water. Let it dry before replacing. Annual service by a pro checks refrigerant, fan motors, and safety controls. Regular split AC upkeep ensures long life and peak efficiency.

Choosing Your Split System

Brands like Panasonic, Daikin, and Mitsubishi offer nanoe™ X or Streamer tech for air purification. These capture dust, allergens, and bacteria. You can also claim Victorian Energy Upgrades rebates on qualifying inverters.
