Fujitsu reverse cycle split wont blow cold

Seems to be no reason for it the machine is operating. Is it the same as a car air con where there may be a gas leak and needs re-gassing? know very little about them and am hoping for an easy fix.

Same as car aircon, but uses different kinds of freon. check first the thermostat setting, may be it set too high. set it to 20'c. if still not cooling, check wiring on ACCU, check capacitor too.

I have a reverse cycle 4 year old fujitsu air con and when I turn it on it automatically just blows air not cold air - it seems to divert to sleep almost immediately can u help.

It should still be in warranty as Fujitsu usually goes for 5 years. Get in touch with Fujitsu to find a local warranty agent. There's not enough info in your post for a diagnosis. Are the lights flashing? If so, what sequence are they flashing? Does the indoor unit otherwise work normally in 'fan' mode? What model do you have?

Water is coming out of indoor mini split. At present time high humidity. Fujitsu machine. Filters are clean, serviced by tech.

It probably has a blocked drain. A bit of liquid bleach into the condensate tray and let it sit for a while before running the air con to flush it down usually does the trick. Otherwise you may have to insert a tube into the drain and blow it clear.

I have a panasonic inverter air con. Model CU-E18LKR. it's not cooling properly. Seems to be blowing cold air out on th outside rather than inside.need instructions on troubleshooting

This is a reverse cycle (heating and cooling) model. It sounds like you have it in heating mode. Check the Panasonic website for an owners manual.

Ford Focus air con not working

Unfortunately air con units are pressurised with a volatile gas which over time "leaks" out and eventually stops cooling any air .you will need to have it re gassed or repressurised...ballpark figure is about £75 to have done but you may find someone who can do this cheaper.system need re gassing every so often.

My Honeywell thermostat isnt keeping my house cool even though the temp is set to 69. Currently 90 degrees in here

Its probably not the thermostat. The air conditioner may be stuck on heating mode. If its a reverse cycle, the reversing valve may be jammed so even when the thermostat is calling for cold air, it stays on heat. If the machine is on heating mode, it should be blowing cold air out of the outdoor unit of the air con. If its on cooling mode, the outdoor should be blowing hot air.

Audi TT 225 aircon condenser slight leaking from top.

Hi Andy
As Roger said take it to an AC specialist and have it checked, it will probably need re-gassing. AC gas leaks show up as an oily substance.

A/C re-gassed and still does not work ?

You first have to be sure that they have charged the system with the correct amount of refrigerant, not too much, not too little. -2) Refrigerant level could be just right, but if Radiator cooling fans are not working at full speed, a/c won't get cold. -3) a/c condenser [the thin radiator in front of the Radiator] has to get good air flow through it to cool the refrigerant & bring the pressure down.. check for blockage of air flow there.-4) if al else fails, have refrigerant drawn out, evacuate system to -25 psi vacuum for 45 min. then recharge system to proper level by volume in lbs. & oz's., not just psi. pressure. This will ensure correct refrigerant level for optimum refrigeration.

Fijitsu wall mounted split system operation and timer lights are flashing, and the air con is not blowing cold air, only like fan operating even in cool mode.

This the common problem with all a/c holders. Without knowing the function of Timer on and Timer off, if it's pressed the unit will start only at setting time.

Please remove the battery from your remote and reset it. And then with use of your manual, set the timer if you need., otherwise normal function will be activated.
