We have decided to go ahead and fix the new aircon unit in the bedroom. The old unit is more than 10 years old and is starting to give us some problems. During discussions with the contractor, we also realised that the bedroom ceiling can be raised about a foot higher.
This was good news since the current ceiling is unusually low and is made worse with our unusually tall bed.
The work started yesterday and the house is now a giant dust ball. Hopefully it will be done by tomorrow and I will get to move back into my room.
I do wish we could raise the ceiling right up to the wooden slates you see there but it is not possible.
