Having problems with your Air Conditioners ?

Hoi... 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

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 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?
