Having problems with your Air Conditioners ?
We have a Condura split aircon of 1.5 hp. 12.000 Kj/hr -R22
The in- and outset unit needs cleaning and has to be disconnected from each other. Here's my question: After connecting again and vac.sucking, how much Freon I have to add? Have I to add it by turning unit and what pressure I will see on my gauge.?I can repair my car air-con, have also tools gauges and pump but have no experience with split-aircons. Maybe you can tell me the way how to work after cleaning and connecting the un
Hi Frans! I'm Roger. I have never had to disconnect the Evaporator from the Condenser to clean them but here is your answer. Use the access valves on the liquid side of the condenser. After evacuating, let the vacuum pull liquid R22 into the liquid line access valve to about 80 gauge pounds and close your refrigerant port on the manifold. Start the unit and add GAS to the suction port to bring your pressure up. If you have a scroll type compressor you can add liquid to the suction port but add gas just to be safe. Exactly how much you add depends on the efficiency of the compressor and how cold you want the discharge air to be. Normally we shoot for 34 to 40 degree evaporator with 18 to 25 degree temperature drop across the coil. R22 at 34 degrees is 60.2 PSI (Pounds per square inch) on your compound gauge. That's normally blue and on the left side of the manifold. The gauge that's hooked to the suction line. 40 degrees is 68.6 PSI. The amount it will take depends on the size of the condenser and length of your line set. Watch the amp draw on the compressor while charging. The name tag will have an RLA or FLA number that is the normal operating amperage of the unit. Add gas on till the suction line is cold at the compressor, then wait 5 or 10 minutes for the system to stabilize. Adjust you pressure again and you should be done. Let me know if you need anything else and if so, be as specific as possible. Roger

Hi ...we have a split fujitsu air con for just over 5 years. The compressor in the outdoor unit is not starting up and the indoor unit blows ambient air. The operation light is lit and the timer light is continuously flashing when in use. Have reset the breaker and the units and also the remote to no avail. Can't find any info on the net or in the manual. Any tech help most appreciated. (Also doesn't seem to be a auto/manual reset buttn as such in the indoor unit)
There is a relay that the thermostat pulls in, in the unit outside. When this happens, the compressor pulls in and the unit outside will run. The compressor has to run before the unit will cool. ... Fujitsu 24C1 Air Conditioner

When turn on three eighth pipe freezes up air con does not blow cold air split system i also noticed the compressor is very hot even after the unit has been switched off.

We have a split system LG air con. Our local people cannot help us. The problem we have is that the unit seems to give off an offensive, unhealthy musky smell when not in use & also the temp when set at a certain degrees (eg. 23) within a few hours of use the temp drops to 19 deg or lower without lowering the controls.
There are two problems in your a/c. 1. Smell. 2. over freezing. The solution is 1.service the unit completely. 2. replace the room thermostat sensor. Sometimes, the room sensor may be working alright after servicing the unit. All the best. ... LG Air Conditioners

I have a Tempstar 9000 airconditioning unit and while I was weed wacking I accidently cut a wire to the unit.

One wire connects to the a/c unit and the other to the energy saver. If I push the connector on the unit with the panel off the unit will run. Cansomeone tell me how to connect those four wires?

No cooling I received a call from my tenant that they have no ac. When i get my inspection of the unit to find an extremely durty air filter, which i replaced.

We had a service technician come out and work on our a/c unit yesterday. He replaced the fan motor (only 2 years old) and insisyed that the fan blade needed cleaning. Next, he said we needed freon, but that the company policy stated that they would not add freon to a unit without first cleaning the coils ($188 for the cleaning). We have never had a technician tell us this before. Sounds like a way to make more $. Can you confirm if cleaning the outside coils is absolutely necessary before a
In short, yes, you have to have the outside coils clean before adding refrigerant so that you can correctly charge the unit. Dirty condenser coils will cause a rise in pressure inside the system because it cannot condense the refrigerant correctly. O ... Air Conditioners
I have an Energy Knight mini split unit. One works fine the other drips condensation EXCESSIVELY. Is something wrong in the unit itself or could the drainage tube be plugged inside the wall. If so, whats the fix? Also, I have another split unit and neither will turn on. This question was asked previously and it sounds like the fuse in the outside exchanger. Exactly how do I get to this fuse to check? Thank you.

I also have a grunaire dual zone mini-split that doesn't work worth a ****. I've had it looked at multiple times and had freon r410a added twice and still nothing.

I have 3 Fujitsu heat / cooling multi split ductless units connected to one rooftop unit. Only in heating mode and only coming from the same indoor unit is a loud almost screeching/vibration sound. It can happen after the unit is on 30 mins or sometimes not until the next day. Repair techs are stumped as they don't see anything wrong and of course the noise doesn't happen when they are here. The noise is so loud I have to turn the unit off. Does anyone know what this could be?
