Size it to the room
Too small and it runs flat out and struggles on hot days. Too big and it costs more and cycles on and off. Room size, ceiling height, insulation and windows all count.
A split system is the simplest way to heat and cool a room. An indoor unit on the wall connects to an outdoor unit through refrigerant lines, and most are reverse cycle, so one system cools in summer and heats in winter.
A split system install has two parts. LENNELEC partners with a licensed air conditioning specialist, who installs the units and does the refrigerant work, while Joel looks after the electrical side: switchboard capacity, a dedicated circuit, and the isolator and connection at the outdoor unit. Joel arranges the whole job with you directly, so you have one person to deal with from start to finish.
What’s involved
- Site check and sizing for the room
- Switchboard capacity and a dedicated circuit, by Joel
- Units and refrigerant lines, by the licensed A/C partner
- Isolator and electrical connection, by Joel
- Commissioning, testing and certificate
Place the outdoor unit well
It needs airflow, a solid base or wall bracket, and a spot where the noise won’t bother you or the neighbours. Near the coast, a sheltered spot helps it last.
Check the switchboard
Larger systems need their own circuit and spare capacity on the board. Older switchboards sometimes need an upgrade first.
Bigger or multi-room homes may suit more than one split system. Joel can talk you through the options for your space.
Arrived on time, completed the job nil issues and very reasonable price.

Who does the split system installation?
Two licensed trades. Joel does the electrical work: switchboard capacity, a dedicated circuit, the isolator and the electrical connection. LENNELEC’s licensed air conditioning partner installs the units and does the refrigerant work, which needs an ARCtick licence. Joel arranges both with you directly.
What size split system do I need?
It depends on the room’s size, ceiling height, insulation, windows and which way it faces. As a rough guide, a small bedroom might suit about 2.5 kW, while a large open-plan living area can need 7 kW or more. Your system should be sized for your space before you buy.
Does a split system need its own circuit?
Larger systems usually need a dedicated circuit, an isolating switch next to the outdoor unit, and enough capacity on the switchboard. Joel checks what your system and switchboard need.
Is reverse cycle air conditioning good for heating?
Yes. A modern reverse cycle split system is one of the most efficient ways to heat a room with electricity, and usually cheaper to run than plug-in electric heaters.
Can you do split systems for businesses?
Yes. LENNELEC does commercial electrical work as well as homes, including offices, shops and hospitality spaces. Call Joel to talk through the job.
Is the installation certified?
Yes. In Victoria, a licensed electrician issues a Certificate of Electrical Safety for the electrical work, and refrigerant work must be done by an ARCtick licensed technician. LENNELEC is a Registered Electrical Contractor, REC 31663.
