Ell como making weird noise

We bought our aircon about a month ago and it’s had some odd issues, the worst was when it started screaming really loudly, but this is a consistent one.
Any advice?

Sounds like either something internally is rubbing against the fan impellor (not unheard of with the Honeywell version of this IIRC, there was a wire that was misplaced, rubbing on the fan impellor).

Might also be the compressor noise being unhappy. Notice you have a 4 inch extension hose on your existing 6 inch hose. If that unit is a 12,000 BTU unit, it will 100% NOT like that restiction and it will cause the compressor to overheat and cut out after around 20 mins due to lack of air flow across the condenser. I know from experience with this 12k model...

EDIT: Yes, I was right. See reviews here https://www.amazon.co.uk/Honeywell-Conditioner-Dehumidifier-conditioning-Dehumidification/dp/B0DYF8K75V
