Split system installation is normally a two trade job: an electrician to run the dedicated circuit, and a separate refrigerant licensed technician to handle the unit and refrigerant connection. Nexus Electrical Co is different. We hold both an electrical licence and a refrigerant licence, so the entire installation, electrical and refrigerant, is completed by the same technician in a single visit. No waiting on a second trade to become available, no coordinating two separate appointments, and no gap between the electrical work being finished and the unit actually being connected and running.

What a proper split system installation involves:

  • Assessing the room and the existing switchboard
  • Running a dedicated electrical circuit (most split systems need one)
  • Mounting the indoor and outdoor units
  • Connecting and testing the refrigerant lines
  • Confirming everything is working and compliant before sign off

Skipping any of these steps, or splitting the job across two trades with a delay in between, is where most installation problems come from.

Nexus Electrical Co installs split systems across Perth for homeowners who want the job done properly, in one visit, with a fixed price agreed upfront.

They were very friendly and listened carefully to what we said. In my place, we had an ongoing issue of water leakage in the shower for so long, however, it is now fixed permanantly. They also showed to me the actual issue and how they fixed it and that was the best part of thier service.
