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.

Good luck.

It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.

SOURCE: My central air conditioner is making a whistling

Hello,
If there is no cooling (meaning no cold pipes and not blowing cold air) then check the outdoor A/C for any visible/obvious issues; breakers not tripped, no debris blocking the outside unit from passing air through it, etc. If all looks ok, you can start checking some things inside of the unit if you feel comfortable doing so. Also, most indoor heaters have a higher speed/rpm for the fan when the cooling kicks on, and the heat runs on a lower speed/rpm.

Hope this helps James

AC is not cooling


Problem #1:Outdoor condensing fan motor has stopped running. This problem could be caused by a bad motor run capacitor. If your motor capacitor is not the problem, then more than likely you need a new motor. Is the fan blade tight, stiff or hard to turn? If the fan blade is hard to turn then you probably need a new motor. Problem #2: Air conditioner compressor will not start. When power is applied to the air conditioning outdoor unit the fan starts, but you hear a sound like the compressor is trying to start, "UGGG"..., for about 5 to 10 seconds and then all you hear is the outdoor condenser fan run. The compressor is locked and will not start. What is happening is the compressor is trying to start, but because the compressor motor is locked it tries to start for a few seconds and then because of the high amperage being drawn goes off on internal overload. The internal overload protects the compressor windings from overheating and burning up. I see this many times during the start of the air conditioning season. Some compressors just have a hard time starting after sitting all winter long. Some compressors are locked up so bad that I can not start them and must tell my customer that they need a new compressor . Many times I can get the compressor started again without having to buy a new compressor or new air conditioning system by using the device that is called, "Super-Boost." I keep two or three of these on the truck. They have saved many of my customers from having to buy new air conditioning systems.

TOYO TA-09CHS aircon problem


TOYO mini split air conditioner made in Japan is very very good quality and it can runs for 20 years without any problem. You didn't hire a best ac technician to install your TOYO unit. The tubing connection between indoor unit and outdoor unit is not the right torque and refrigerant leak. Your TOYO unit runs out of refrigerant. You need fix the leak and fully charge the system. You will solve the problem.
