Question about Fujitsu Heating & Cooling
HELP!!!! We just installed Fujitsu A/C system consisting of AOU24RML1 and AOU36RML1 outdoor units with five indoor units (ASU 12RMLQ and ASU9RMLQ).
The system has not worked consistently since the installation. Whether the cold air blows from the unit appears to be random and independent of the temperature of the room, the temp. setting on the wireless remote or the outside temperature. While the blowers appear to be working fine, the problem is that the air being blown is never consistently cool. Even the indoor units supplied by the same outdoor unit would work inconsistently, i.e., while one unit would continue to blow cold air, the other unit would blow only tepid. This would be the case even when the temperature of the rooms are about the same. For example, we've had 90+ Fahrenheit weather in the area and with the wireless remote temperature set to 68 to 70 degrees, the system would sporadically and barely cool the rooms down to maybe 78 to 80 degrees.
I've also noticed that copper tubing connected to the condensor unit outside would be covered with ice when the compressor is running.
Any ideas/suggestions would be greatly appreciated. So far, the installer is insisting that this is a design flaw of the Fujitsu system. And I've only received perfunctory response from the Tech Support at Fujitsu USA.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

- Calibrate your electronic thermostat if it is accurate. If not then replacement is needed.
- Check the location of your electronic thermostat, it may be installed in the room where its too cold.

This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.

Make sure your vent is closed. check the filter to see if its clean. If you run the a/c you can check your evaporator to see if you have condensation or does it freeze up?
Make sure you have your unit on early in the morning. If you turn it on in the afternoon the humidity might be too much and it will take along time to cool down.
Try those things if that doesnt work then you need a service call.
