| FTXD60/RXD60 | $0.31 | 3.5 |
| FTXD71/RXD71 | $.40 | 3 |
| FDY45 / RY45 | $0.25 | Energy efficiency is directly related to duct and outlet design. To minimise energy loss it is good design practice to use a central air distribution system and install the outlets as per recommendations. A 6 outlet system with inline dampers can account for an additional 6% energy loss and this will require a larger unit with higher running costs. |

| FDY71 / RY71 | $0.40 | |
| FDY90 / RY90 | $0.52 | |
