Split-system, ducted, and multi-head AC installation across Brisbane homes and businesses.
Whether you need a single split-system in the bedroom or full ducted air conditioning across a multi-storey home, Miranda Electrical handles the full install from sizing to commissioning. We're fully accredited and refrigerant-licensed so your warranty stays intact, and we tidy up everything before we leave.
Morningside, Carina, Camp Hill, Coorparoo, New Farm, Hawthorne, Bulimba, Norman Park, Cannon Hill — and the wider inner-east Brisbane area for ongoing commercial clients.
Sizing depends on room area, ceiling height, sun exposure and insulation — a small bedroom typically wants 2.5kW, a large open-plan living area might want 7-8kW. Undersizing means the unit runs flat-out and wears quickly; oversizing wastes power and dehumidifies poorly. We measure the space, ask the right questions, and recommend a size that will actually keep up on the hottest Brisbane days.
Yes. A complete install with us covers the indoor head unit, the outdoor compressor, brackets, refrigerant lines, drainage, electrical connection, and commissioning. We're refrigerant-licensed so your manufacturer warranty stays valid, and we leave the site clean — no patching holes or chasing other trades.
Yes, including new ducted systems and retrofits to existing homes. Ducted is the right call when you're conditioning multiple zones, you want a clean ceiling with hidden grilles, or you're building / renovating anyway. We coordinate with builders, plasterers and roofers as needed so the install lands without surprises.
Modern inverter splits and ducted systems are dramatically quieter than the units they replace — typically 25-35 decibels indoors, which is quieter than a fridge. The outdoor compressor needs to be sited thoughtfully (we discuss this with you before drilling), but inside the home you should barely hear it during normal operation.
Annual or 18-monthly service: clean the filters, check refrigerant pressures, inspect the outdoor coil, verify electrical connections, and confirm drainage is flowing. A unit that's serviced regularly will outlast an unserviced one by a wide margin and will run more efficiently the whole time, which shows up on your power bill.
Most modern boards (RCBOs, labelled circuits, dedicated AC circuits) handle it without modification. Older ceramic-fuse boards almost always need an upgrade — both for safety and to register the new load correctly with your insurer. We'll check during the quote and tell you straight if a board upgrade is needed first.
A single split-system in a straightforward location is half a day. A multi-head install across several rooms is one to two days. Full ducted retrofits, depending on the home, run two to four days. We confirm the timeline in writing before booking.
