Like many on this forum, I can attest to how LOUD this AC unit is, with that horrible rolling, moaning, thumping noise every 10-15 seconds. The installers came out to take a look and reckon that's how it's supposed to work.

The unit hits 50-55dB when we're sitting INSIDE the house. Next to the unit, it runs above 80dB. EVERY 10 seconds it spikes into a thump.

Here's a video for your enjoyment...

Now, if it worked amazingly well, we would don some earmuffs and live with it. But it's a sweaty mess inside the house during summer when the unit just struggles.

Four weeks ago we replaced our 15 year old air conditioning system for an Actron Air ESP model. We are delighted at how nicely it cools our home on hot days and at its whisper quiet operation. The old unit was louder than a jet on take off while running and made us feel guilty about the noise we were inflicting on our neighbors when we ran it. Now we can enjoy cool comfort without guilt, also knowing that our electricity bills will be much lower as the ESP design makes this unit much more efficient than the old one even though both have the same 23 kW capacity compressor.
We believe we made a good decision to purchase an Actron Air unit, even though it was not cheap, expecting many years of good service.

We rarely used the system and for the first two years it was ok, although the air distribution was not even throughout the house.
Then drama after drama with it barely working. Lots of expensive service calls which actually seemed to make things worse, really!
We purchased the supposed Rolls Royce version but I think it's more like Kia Rio on 1 cylinder.
In short, dud product, lots of promises, servicemen who didn't seem to know what they were doing and super expensive for an appalling experience - look elsewhere! You've been warned.
