The old unit was still working but on it's last legs. The bottom of the outdoor unit was completely rusted out and upon removal it completely fell apart. The client opted for a new 12.5kw Daikin reverse cycle ducted system. The roof space was tight which meant the new indoor unit had to be relocated. On completion the difference was drastic in efficieny and sound level. The old unit could be heard running from the neighbours house whereas the replacement Daikin was so quiet that you barely knew it was running. Easy to operate, 5 years warranty and the client was over the moon!
