Professional split system air conditioning installation for homes across Melbourne's Eastern Suburbs. Heating and cooling in one unit - energy-efficient, quiet, and perfectly sized for your space.
Supply and installation of premium split system air conditioners from leading brands. We handle everything from site assessment to final commissioning, ensuring your system is correctly sized and positioned for maximum efficiency and comfort.
Upgrading an old or failing unit? We remove your existing system and install a modern, energy-efficient replacement with minimal disruption. You will notice the difference in performance and running costs immediately.
Regular servicing extends the life of your split system and keeps it running efficiently. We diagnose and fix faults fast, from refrigerant leaks and compressor issues to faulty control boards and blocked filters.
A split system is the most practical way to add heating and cooling to a Melbourne home - no ducting required, no gas line, no major renovation. A modern reverse-cycle unit handles both summer and winter from a single wall-mounted head. Today's inverter models run quietly, lock onto temperature fast, and cost significantly less to run than the older fixed-speed systems they replace. We size every install to the room so you get real comfort without wasted running costs.
We supply and install leading brands including Panasonic, Daikin, Haier, Fujitsu and more. Every system we install is backed by a full manufacturer warranty and our workmanship guarantee.
The cost of a split system installation varies depending on the unit size, brand, and complexity of the install. Most residential installations range from $1,800 to $4,500 fully installed. We provide free on-site quotes with transparent, upfront pricing - no hidden fees.
The right size depends on your room dimensions, insulation, window orientation, and ceiling height. As a rough guide, a 2.5kW unit suits a small bedroom, while a 7-8kW unit can handle a large open-plan living area. We measure up during your free quote to recommend the ideal size.
Most split system installations are completed within 3 to 5 hours. If pipework needs to run through walls or ceilings, it may take a full day. We always aim to leave your home clean and tidy.
Yes. Modern reverse-cycle split systems provide both heating and cooling from one unit. They are one of the most energy-efficient ways to heat your home in winter and cool it in summer.
We install and service all major brands including Daikin, Panasonic, Fujitsu, Haier, Mitsubishi and more. If you have an existing unit that needs repair, we can help regardless of brand.

Would highly recommend OnePeak!! Our evap run its course and needed to be changed. We had a few people have a look at it and decided to go with Lachy! His personality and transparency put us at ease.

Lachie patiently discussed the cooling options available to us and we decided on 3 individual split systems. His team arrived at the agreed time and worked in an efficient, professional manner. They cleaned up carefully after the job. We are very happy with the work and the cost of the job, and highly recommend them.

Highly recommended. Lachy fixed the gas heater at a highly competetive price. He did a fantastic job, so we got him to service the evaporative cooling. Again, Lachy was fantatsic, did a great and thorough job. We are recommending him to everyone.
