3 rd floor office in a multi level building, so ceiling is concrete slab
They have an underceiling hitachi PR5HMK that is 30 years old. It's blows into a plaster board bulkhead that feeds into two registers.
The a/c still works as good as it could, they just think the thermostat is just a little iffy.
I would install a new thermostat, (quoted them on that years ago), but probably a waste of money as they need something better.
Maybe the t/stat wouldn't be a waste of time as they could use the same t/stat if they bought an australian made ducted system and mounted where the under ceiling unit is now if this a/c eventually dies in a few years, (they come without t/stat and use the same type as I'd try installing anyway).
Room is 6m x 8m. Existing condenser unit it one level up, on the roof.
7834
Assuming they don't want to replace the unit, what could I say to them?
