Services
Air-Conditioning Systems
Our Daikin ducted and split air-conditioning systems provide efficient climate control for residential and commercial spaces. Using inverter technology, these systems adapt to weather conditions while reducing energy consumption. Ideal for Melbourne's variable climate, they offer zoned temperature management through smart controls like MyAir and Google Nest.
Hydronic Heating
Nexura hydronic systems deliver even warmth through water-based underfloor or radiator setups. Customisable to existing or new builds, these systems integrate with renewable energy sources like heat pumps. They provide silent operation and improved air quality compared to forced-air systems, ideal for allergy sufferers.
Geothermal Heatpumps
As IGSPHA-accredited installers, we design geothermal loops that harness stable underground temperatures for year-round climate control. These systems reduce energy use by up to 60% compared to traditional HVAC, with options for water-to-air or water-to-water configurations suitable for large residential properties.
Solar PV Systems
Our LG Solar and Enphase microinverter setups generate clean electricity while maximising energy independence. Designed for Melbourne's sunlight conditions, these systems include smart monitoring and can be paired with sonnenBatterie storage for 24/7 renewable power usage and grid independence.
Heat Recovery Ventilation
VLR 70 S units exchange stale indoor air with filtered outdoor air while retaining temperature efficiency. These systems reduce condensation and improve respiratory health by maintaining 95% humidity control, particularly beneficial in airtight modern homes.

IEnergi installed Daikin 16 KW Premium ducted Air conditioning system (Inverter type split system) in my house in 2018. Now it is 18 months and so far it is working very well. Mr, Michael of iEnergi is very professional and provided me immediate support over phone a couple of times on my questions on the control system. I have 8 zones and the My Air control system provided and installed by iEnergi is excellent and saves power.

Following a fire which destroyed out wood fired hydronic heating unit we decided to replace it with air to water heat pumps. Great decision. iEnergi installed the pumps and we were very comfortable in our home last winter. Nice to have an automated and controlled system instead of loading wood into a furnace. iEnergi were very professional, punctual and transparent with their intentions and activities. They also provided a computer generated heat requirement for our home which has proven to be quite accurate. Great outcome and experience.

Very fairly priced, friendly and knowledgeable. I would recommend iEnergi without hesitation.
iEnergi removed gas central heating, evaporative cooling and all old ductwork in my 20 year old double storey home. They replaced this with a central inverter system with brand new ductwork and numerous return outlets, paired with an 11-zone controller unit. From first contact, Michael has been knowledgeable, friendly and punctual. We have spent countless hours on the phone exchanging tricky design details. Not once did I ever feel rushed/pressured and this was all prior to a single cent being paid!
