FAQ
Common questions.
How much does split system installation cost in Perth?
Cost depends on the room size, unit capacity, and how straightforward the electrical and mounting work is. We provide a free on-site or phone assessment so you get an accurate, no-surprises quote before work begins.
What size air conditioner do I need for my room?
The right capacity depends on your room's size, ceiling height, insulation, window area, and orientation. We size systems properly during your quote rather than guessing — an undersized unit runs harder and costs more to operate.
Is ducted or split system better for my home?
Split systems suit single rooms or budget-conscious upgrades, while ducted systems suit whole-home comfort with room-by-room zoning. We'll talk through your layout and goals to recommend the right fit.
Do I need an electrician to install air conditioning?
Yes — air conditioning installation involves dedicated circuits, safe isolation switches, and compliant wiring. As a licensed electrical contractor, Diamper handles the electrical and mechanical install as one accountable team.
How long does installation take?
Most split system installs are completed in a day. Ducted systems typically take longer depending on the size of the home and duct run complexity — we'll confirm timing during your quote.
Do you provide a compliance certificate?
Yes. All installations are safety tested and a compliance certificate is provided as part of your handover paperwork.
What brands do you install?
We work with all major brands, including Daikin, Mitsubishi Electric, Fujitsu, Panasonic and Actron Air. Get in touch if you have a specific brand or model in mind.
