Air conditioning installation

Installing a complete air conditioning system is more than just hanging a unit on a wall and plugging it in. Our approach to air conditioning installation starts with an in-depth site survey, where we assess room sizes, sun exposure, and airflow patterns to select the right capacity and type of system for your needs. We then position the indoor unit high on a wall for optimal air distribution and install the outdoor compressor on a stable, ventilated base. Next comes the precision work: routing refrigerant lines, condensate drains, and power cables through a neatly sealed wall penetration. After a thorough vacuum to remove any moisture from the refrigerant circuit, we charge the system to exact manufacturer specifications. Finally, we run a full operational test—verifying heating, cooling, airflow, and system noise—before tidying up and handing over a clear user guide. Whether it’s a single-room split or a multi-zone multi-split setup, our expertise in air conditioning installation ensures reliable performance and long-term efficiency.

Split system air conditioning installation

Split systems remain a top choice in Melbourne for their quiet operation, energy efficiency, and precise temperature control. Each split unit consists of a sleek indoor head and a compact outdoor condenser. When you choose our split system air conditioning installation, Thomas Group Electrical’s certified technicians handle every step: mounting the indoor bracket, drilling and sealing the line-set hole, mounting the outdoor unit on anti-vibration pads, and connecting the refrigerant and electrical circuits. We then evacuate the lines, charge the system, and calibrate the controls so you can switch effortlessly between heating and cooling modes. Multi-head configurations allow you to run up to four separate indoor units from a single condenser—perfect for homes with several living areas and bedrooms. We ensure each head is sized correctly and wired to its own zone controller, giving you individual room comfort without the cost or complexity of ductwork.

Ducted air conditioning installation

For seamless whole-house or large-office comfort, our ducted air conditioning installation service integrates a central inverter compressor with a network of discreet ceiling or under-floor ducts. We begin by designing a tailored duct layout that balances airflow and static pressure to each room. The outdoor compressor is sited for ease of access and noise control, while the indoor evaporator and air handler are hidden in the roof cavity or under the floor. We install insulated ductwork, flush-mount vents, and a programmable zone control panel so you can set different temperatures for bedrooms, living areas, or workspaces. During commissioning, we test static pressure, airflow rates, and thermostat accuracy to ensure each zone maintains the desired set point. This approach gives an even temperature without hot or cold spots, and the energy-saving inverter technology adapts to changing load conditions. With ducted installation by Thomas Group Electrical, you get maximum comfort with a clean, unobtrusive interior finish.

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!
