Bonjour ! Est-ce que certains d'entre vous ont la clim Murao smart 3,6kwh et peuvent me dire s'ils en sont satisfaits ?

So I have a Whynter Arc 131 GD dual hose AC and fortunately don't have to use it all the time. Anyways I have noticed that sometimes when the compressor kicks on the motor will make a brief buzz sound as it comes on. Other times I can turn it on and the unit barely makes a peep outside of the fan blowing the air. Does anyone know what might be causing this or if it's anything to worry about?

Thanks.

I am renovating my house, and while it is being knocked about, I would like to install air-conditioning. I have found a really nice looking system that is in my budget. I am an engineer, and am also qualified in electrical installation. But I am not an aircon guy.. would I be able to run the power and all the pipes, mount everything on the walls and the like; to keep the costs down, and then get a proper aircon chap to connect the gas bits?

The manual says it could be in one of two places, but I don't see either one. And I don't see anyone discussing this online. Where do I go to ask people to post a picture of theirs?

I need advice or to know if this has happened to anyone else.

​I installed a new GE Heat Pump unit. After installing it, the low line was reading 90 PSI. I added refrigerant R454B and it wouldn't go above 125 PSI on the low line and 300 PSI on the high line. The low-line temperature is 68°F and the high-line temperature is 75°F. The thermostat setup is correct. When I turn on Cooling, it doesn't cool, and when I turn on Heat, it continues running in Cooling mode. I configured the thermostat to 'O' and to 'B', and it keeps doing the same thing and the fun is running good. Please help

Living in Philippines. My room is pretty small probably around 5 steps to get from one side to another. I'd prefer something really quiet and that would save me money on my electricity bills.
No budget but I do prefer the bang for buck recommendations heh.

New homeowner with new AC unit so don’t know much here other than my smart thermostat is telling me it’s time to change the filter. Existing one looks significantly smaller that the space its installed in.
