Heating and Cooling for your home - Bentleigh


We install, service and repair a wide range of air conditioning systems, and work with all brands on the market.

Evaporative cooling – For the budget conscious, this option is the cheapest out there but still delivers quality cooling and operates with high efficiency, meaning you’ll be able to keep running costs down.

Add-on cooling – This option cools and heats rooms through a gas deducted unit. Generally for heating, the addition of some components and refrigerant transforms it into both a heating and cooling system which is a fantastic option because it saves you from having to install two separate units.

Wall split systems – These are best suited for a specific room – for example bedroom, study or lounge. Mounted on the wall, the wall split system offers ease of use, low fuss and cools the desired area quickly.

Ducted split systems – Top of the line quality that not only offer excellent cooling for your home through ducts, but also offer heating for the cooler months. Ducted split systems are usually a little more costly to install, but more than make up for the initial investment in quality, reliability and energy efficiency.
