Split-System Air Conditioning FAQ
Your complete guide to split-system air conditioning, addressing common queries about energy savings, optimal performance, smart features, repairs, and choosing the right system for your home or business.
Yes.
Only ARCtick-certified technicians can install or handle refrigerant gas under the Ozone Protection and Synthetic Greenhouse Gas Management Regulations.
We hold both:
• ARCtick licence (refrigerant handling)
• WA electrical licence for safe power connections.
This means the indoor and outdoor units are mounted on opposite sides of the same wall, allowing:
• Short pipe runs
• Lower labour costs
• Easier drain line routing
Ideal for bedrooms and small units with nearby external walls.
Yes, for units over 3.5kW.
Per AS/NZS 3000, any fixed appliance over 10A or 2400W should be on a dedicated circuit, protected by:
• An RCBO (RCD + breaker)
• An external isolator switch near the outdoor unit
We upgrade boards if required and test all connections.
Yes. We install BYO units as long as:
• It’s brand new
• It has an Australian plug/RCM compliance
• It comes with a valid warranty
We’ll still issue a Certificate of Compliance for the install, and your manufacturer warranty remains valid.
• Back-to-back: 3–4 hours
• Extended run or second-storey: 5–6 hours
We aim to complete installs in one visit and clean up fully before leaving.
Yes—reverse-cycle units can both heat and cool.
They're among the most efficient forms of heating in Perth’s winter, with a coefficient of performance (COP) > 3.5—meaning 1kW input delivers ~3.5kW heat.
Best practice includes:
• High on the wall, central to the room
• Avoiding placement above beds or desks (cold air drop)
• Away from direct sunlight or heat sources
We guide placement during the inspection for airflow and aesthetics.
Yes—we:
• Run a nitrogen pressure test to 500–600 psi
• Perform a vacuum pull to remove moisture
• Top off with manufacturer-spec refrigerant (if needed)
This ensures no leaks or moisture contamination, as required by AS/NZS 5149.
Yes, but it requires:
• A longer pipe and drain run
• Wall or ceiling access for cabling
• Often a condensate pump if gravity drain isn’t possible
We assess the feasibility and quote accordingly.
• 5-year manufacturer warranty (on the unit, when installed by a licensed installer)
• 5-year workmanship warranty from McGuire’s
We register units with suppliers (if purchased through us) and provide your compliance certificate post-install.
