Cassettes · 03 Cassettes sit in an Armstrong ceiling and throw four ways — useful for offices, shops and cafés that do not need hidden ducted. Aurum Prodest checks void height, fits a drain pump and does not trap service behind a sealed panel.
Cassettes like 600×600 or 800×800 grids and void depth for the chassis. Plasterboard needs a frame and hatch. Four-way throw beats a wall unit in a square hall; a narrow corridor wants ducted or wall.

Condensate almost always needs a pump, safety tray and trap or you stain a tenant ceiling. Pipework is light-commercial: vacuum required. We check noise at medium speed, not the advert “turbo”.
Service: the panel comes off, filters wash — easier than a ducted hatch behind a cupboard. Shops at night. 5-year workmanship. Compact 60×60 vs large hall cassettes.
We do not drop a cassette into a stretch-ceiling flat without a box — it becomes an island everyone sees. Supply grilles should not sit tight against the cassette (short-circuit).
Split install is easy to do badly: short vacuum, drain into the wall, outdoor with no isolation.
Multi-splits go on façades that cannot take a row of outdoor units. Aurum Prodest counts room diversity and pipe length and does not claim five indoors on a small outdoor will cool like five splits.
AC service is diagnosis, not “a cylinder into the pipe just in case”. Aurum Prodest cleans coils, checks pressures, finds leaks and charges to the brand’s charge. Blind recharge kills compressors.
For splits and multi-splits, class shows in noise, compressor life, and service. Pros and cons show where paying up helps.

Cassette is simpler to service and install on Armstrong. Ducted is hidden grilles and complex throw.
If gravity to drain is impossible — yes. Office towers almost always have a pump.
Yes if you accept a ceiling panel and have height. Most homes take a wall unit.
Louvre and layout. Do not hang it on the workstation without set-up.
Above a wall unit because of pump and ceiling. After looking at the Armstrong cell.
