Our recommendations

One of the most efficient heating units we offer is the Ducted Heating system which is highly effective in heating and cooling your entire home through ducted ventalation systems. These systems have additional bonuses as they can also be converted to a cooling system with add on cooling.

If your cooling requirement is confined to one room, we recommend wall split systems. These have an indoor and outdoor unit and use the latest in-built technology to ensure high performance and energy efficiency. A very versatile unit, it can be used in the summer as an air conditioner. It is best suited for single rooms such as bedroom, a study or living room.

Ducted Split Systems. This works in much the same way as wall split systems, but the indoor unit is fixed and out of view. Ducts which are concealed, carry the heated air through openings which are strategically placed in every room. This is the most high-value heating system we install.
