AC Replacement Services

Every AC Changeover, Done Right the First Time

New units are often more powerful than what they replace. The electrical has to be upgraded to match.

Full Electrical Changeover

Remove old wiring, install new dedicated circuit, fit compliant isolator, and hardwire the new unit. Complete changeover.

Circuit Upgrade

New units often draw more power than the one they replace. We upgrade the circuit, cable, and breaker to match the new load.

Switchboard Upgrade

If your board is at capacity, the new unit will not run reliably. We upgrade your switchboard as part of the changeover.

Evap to Split Conversion

Switching from evaporative to split or ducted? We decommission the old wiring and install a completely new circuit and isolator.

Compliance Upgrade

Old wiring that was fine 15 years ago may not meet current standards. We bring everything up to code as part of the replacement.

Old Unit Disconnection

We safely disconnect and isolate the old unit before it is removed. No live cables left exposed.

Your new air conditioner is only as good as the electrical behind it. If the wiring is old, undersized, or non-compliant, problems are guaranteed.

What Our Changeover Customers Say

★★★★★
"Replaced a 20-year-old split with a new Daikin. The old wiring was 1.5mm on a shared circuit. Response ran a new 4mm dedicated circuit and proper isolator. Night and day difference."
- Greg H., Bayswater
★★★★★
"Switched from evaporative to three split systems. Response removed the old roof wiring and ran three new circuits from a brand new switchboard. Massive job done in one day."
- Sharon T., Maylands
★★★★★
"New ducted unit needed a bigger circuit than the old one. Response upgraded it and had everything ready for the aircon guys the next morning. No delays."
- Peter L., Duncraig
Questions Answered

Air Conditioning Replacement FAQ

Often, yes. New units typically draw more power than older models. If the existing circuit is undersized or non-compliant, it needs upgrading. We check the existing wiring and advise you honestly.
Sometimes, if the existing circuit is the right size and in good condition. But if it is undersized, damaged, or does not meet current standards, it needs replacing. We test it during the on-site check.
It depends on whether the existing wiring can be reused or needs replacing, the cable run length, and whether a switchboard upgrade is needed. Call us with the details for a fixed price.
This is a full rewire - the evaporative circuit is decommissioned and new circuits are run for the split or ducted system. We handle the entire electrical changeover.
If your current switchboard is at capacity or does not have a spare way for a new dedicated circuit, yes. We check this during the on-site assessment.
A simple like-for-like replacement takes 2 to 4 hours. A full system change (evap to ducted, or significant upgrade) may take a full day. We confirm timing when we quote.
