The air conditioning I ordered was delivered to me within 4 days.
(Mid-August during the heat wave !!)
With a little manual skill, self-assembly is no problem.
I have a system with 7 meters of refrigerant line.
Assembly takes approx. 4-5 hours.
The system was already pre-filled with refrigerant.
We use the system in a single-family house and use it to cool 2 rooms of around 20 square meters each.
The performance is absolutely sufficient for this.
