Quick question.

My wall Aircon at home seems to be a bit strange.
It'll blow cold for an hour or two and then seems to pretty well blow like a fan.

Turn it off for awhile and back on and it's cold again.
I thought perhaps (after some googling) it might have been the coil or pipes freezing over at first by manually having the fan speed only set to low but I don't think this is the likely case anymore.

Usually only run on ~25' deg. setting, but setting it lower doesn't seem to change much (i.e. its not just reaching 25' in the room and adjusting).

ooaa.. if its icing up, youll be able to tell by looking under the filter at the cooling coil.

icing is caused by insufficient airflow over the coil, or low gas charge (very unlikely seeing as it works ok to begin with)

so always run the fan on high

otherwise, cutting out after an hour or 2 is caused by the compressor overheating.
so make sure the outside heat exchange coil is clean, can even give it a bit of a hose to make sure its clear of dust and breathing well.

cheers dais for the headsup to this thread :D

gas leak? i got some new ones installed late last year and they stuffed one of the joins so all the gas had leaked which caused it to blow for a while then nothing.

run it and spray some soapy water over any pipe work joins

hose that muddafugga with a medium spray, not too heavy. the outside bit is designed to survive rain etc. hard work to pull it out of the wall. just hose it in place.

box units = unlikely to have a leak.

Alright hosed it off. It didn't.look dirty at all though. Aircon at.the moment blowing cold (has been off for the last couple of.hours) . Off to work.but.ill have my.wife.see how long.it lasts

what.the.hell.is.with.all.the.full.stops.in.your.posts?...

I should have been clearer that mine is a split system.
After the hose off Aircon was on and.fine for a solid hour before.my.wife had to go out. Aircon then off.
Will recheck tomorrow.
Is it likely to.be.gas if.it.runs fine for.that long Scooby?

If it was a problem with the gas it probably wouldn't cool at all. It is either icing over in the evaporator (internal unit) or the condenser is dirty and blocked (external unit). I think I've got that the right way around.
