I will talk about the 24,000 BTU air conditioner that I installed last October. I am very satisfied with its performance, although it did not have to endure heavy winter conditions this year, so it has not been tested in very cold temperatures. It was powerful enough and quickly heated a 40 sqm space whenever needed.
There is a major issue with the installation, as both the external and internal holes need to be sealed. In my case, because it was installed above a sliding balcony door, there was some leakage that affected the thermostat, which is located on the right side next to the pipes.
However, the biggest problem is the noise produced by the internal unit. Regardless of the fan speed, apart from the airflow, there is a penetrating sound that varies depending on the fan's power. It seems to be the noise of the motor, which becomes more pronounced inside the plastic casing of the unit, as if it were a speaker.
Although I called the dealership and they replaced the fan-motor set as a precaution, the noise persists. Only in silent mode is it tolerable, and I will have to get used to it since I spent so much money.
Another issue that most people have mentioned is the limited range of the remote control, where you have to aim precisely for it to work. This practically renders the isense function useless, which is the temperature sensor on the remote control.
When isense is activated, it sends the temperature it detects every 10 minutes, and if the unit does not receive the signal, it does not work. This can be completely resolved if someone with electronic knowledge opens the remote control and moves the infrared transmitter further out with two longer wires, attached closely to the front glass.
Now it can be controlled from anywhere without having to aim at the unit.
Regarding power consumption, I have installed a tapo P110 socket and have observed the following:
- During the winter, it dropped to 550 watts at idle, while in sleep mode, it went down to 450 watts.
- In cooling mode, which has not been used extensively yet, I have seen it reach up to 290 watts in a couple of tests, but I will provide more information when it is tested in higher temperatures.
The artificial intelligence, which no one explains how it works, as far as I have understood from my usage so far, is that when it reaches and maintains the desired temperature, it goes into idle mode and activates the AI, which maintains the temperature in the most economical way without increasing consumption.
Through usage, it gathers some conclusions about the space and how quickly it reaches the desired temperature. So, if we close it and reopen it at some point, it will not need to work at full power but at the necessary wattage to bring the space to the desired temperature.
The external unit does make noise, mostly from the air it expels, but it is not bothersome, although it is quite large.
I did not encounter any issues with the Wi-Fi connection; it connected very quickly. So, anyone experiencing problems should check their router settings.
