What goes into your installed price?
Supply and installation are quoted together after reviewing your property. A basic back-to-back split installation places the outdoor unit close to the indoor unit on a suitable adjacent exterior wall.
- Confirm equipment capacity, mounting locations, access and installation route.
- Specify pipework, drainage, mounting and electrical allowances in your written quote.
- Identify extras such as longer pipe runs, difficult access, switchboard work, condensate pumps or removal of an existing system.
- Complete commissioning, testing and customer handover for the agreed work.
Prices are provided by quotation. No fixed discount or final installation price is advertised until the scope and availability are confirmed.

Do you provide residential and commercial air conditioning services?
Yes. We work across residential and commercial properties in Sydney, from individual room systems to ducted, ventilation and broader mechanical HVAC work.

Yes. Capacity should consider room size, orientation, insulation, glazing, occupancy and intended use. We assess the property before confirming the recommended system.
Do you repair air conditioners that are not cooling or heating?
Yes. We diagnose operational, airflow, drainage, control and refrigeration-related faults before explaining the appropriate repair or replacement options.
How often should an air conditioner be serviced?
The appropriate interval depends on use, environment, property type and manufacturer requirements. Frequently used residential and commercial systems generally benefit from planned servicing rather than waiting for a breakdown.
