Peace be upon you
Used Basic brand AC hot cold is available, normal not inverter.
The AC was working excellently, its cooling is high and its heating is excellent, but it had a bad smell. I brought more than one technician and electrician, and they said there was no apparent problem with the AC. When I disassembled it, the water drain was clogged. After disassembly, it was dripping water, and the probable cause, I think, is incorrect installation.
Now I don't know if the problem will be solved if it is installed excellently, or not, but I think it will most likely be solved.
The AC looks beautiful and modern, and it comes with the remote and copper wires.
