Consider using Reverse Cycle Air Conditioning as a backup heater in the colder months.
In situations where you may choose a cooling system only - it may be a benefit to include reverse cycle as well.
Economical running costs rely on selecting a reverse cycle air conditioner that is the right size for your needs. Accurate sizing is essential before buying a unit and should include a detailed heat load survey of your home by a qualified technician recommended by a unit's manufacturer or retailer.
Under or oversized units will give poor performance. Ask for the reverse cycle air conditioner output capacity to be expressed in kilowatts (kW). Horsepower (HP) is often inaccurate and misleading as it measures the size of the motor, but does not accurately reflect the unit's output.
