Sub Zero knows air conditioning is an important part of creating a comfortable environment in people lives. Sub Zero can help you choose the right air conditioner depending on things like orientation, window size and insulation. An air conditioner that's too large will be inefficient and expensive to run, too small and it won't adequately heat or cool your home.

We can supply quality air conditioners (AC) including our preferred brands, but not limited to such as Panasonic, Daikin, Mitsubishi and Fujitsu.

Home Air Conditioning high wall split systems are designed for all aspects of housing and can be placed usually anywhere throughout a house depending on size. High wall split systems are an affordable option for someone trying to create a comfortable environment for their family on a budget.

Split systems are the most common types of home air conditioning used in a residential sense as installation, initial cost of the system and running costs are a lot more affordable.Split systems can also be used in a multi-head type application where multiple indoor units can be run off the one outdoor unit.
Floor mounted models allow for flexible installation either sitting proud from or semi-concealed from your wall, to a style which best suits the needs of your space. The range of wall mounted reverse cycle split-system air conditioners includes inverter models, suitable for single rooms through to larger open-plan living areas.
Home Air Conditioning Installation of cassette units are extremely discreet with only the grille showing in the ceiling. A cassette type are useful when wall space is limited and the customer would like to air-condition an area with these obstacles. A timer allows you to plan your usage, helping you save on your power bills.
Ducted air conditioning systems can provide you with the flexibility to heat or cool every room in your home. Your home can be 'zoned' to maximise energy efficiency and you can customise your air conditioner's operation to suit your lifestyle - how you 'zone' your home is completely up to you. A ducted AC system works through a series of ducts connected to an internal unit, which is installed either in the roof or under the floor of a home.

The team at Sub-Zero went above and beyond our expectations. Will spent the time to run through our house plan and provide recommendations on what would work best for our space and was always available to answer any questions we had. From our initial consultation through to the installation of our unit, Will communicated and worked in with some fairly tight timeframes to ensure we had the installation completed in time. If you are looking for quality work, product and people, definitely give the guys at Sub-Zero a call.

We used Sub Zero to install our split system air conditioners. Will and his team were very professional and prompt. Tony and Stewart did a very clean job at installing these systems at our place. They were also able to give us a good package deal on the brand of our choice. We highly recommended Sub Zero to anyone looking to do their next air con install.

Highly recommend William and the team. They installed our ‘My Air’ ducted air conditioning system at our residential home and the work was excellent. William’s customer service has been amazing answering any… questions we have had. Stuart also did a maintenance service on our units and he was thorough and completed the job in an efficient time. Highly recommend Sub-Zero Air Conditioning.
