Split or Ducted

Choose air conditioning systems that work best with your home design, preferences, and budget. Air conditioning systems are efficient air-to-air heat pumps that convert each 1kW of power into about 4 kW of heating or cooling.

Consider a split system for a single room, multi split and ducted systems for multiple rooms.

Ducted Systems

Ducted air conditioning systems are a cost-effective way to condition many rooms. Install the ducting in an attic space, bulkheads or under your sub-floor.

Note that ducted systems are not as efficient as split systems due to greater thermal energy loss through the ducting.

Split Systems

Choose a single split system for a single room. This is an efficient and cost-effective option. For many rooms, choose a multi split or ducted system. More information.

For a large home, consider a multi split system with variable refrigerant flow (VRF / VRV). These systems automatically adjust the amount of refrigerant depending on how many indoor units are switched on. This makes them very efficient but more costly to install than basic multi split or ducted systems.

Systems Mix

Consider a mixed approach to air conditioning your home, especially if it has two levels. Explore hydronic heating for your ground floor and multi split or ducted air conditioning upstairs.

This approach uses the rising warm air to minimize the need for heating on the first floor.

In summer, cool dehumidified air from your air conditioner falls to the ground floor to reduce the need for cooling there.

In addition, shade your windows from sunshine radiation in summer and use ceiling fans to reduce your air conditioning.
