Portable air conditioner works fine, but now developed a rhythmic thrumming noise. Tilting it to the left, and only to the left, by raising the right side ~2cm/1" alleviates problem and gets better airflow...

I'm terribly heat adverse and my two best purchases in the last decade was LASIK and my portable air conditioner. I'm currently more poor than usual and am completely unable to afford to buy a new air conditioner.
It's a portable unit, works great, but after setting it up and breaking it in, a month ago, I just turned it on for the second time this season. Startup is fine, but after getting warmed up, it makes a rhythmic thrumming sound (about 1-1.5 Hz). There's still airflow, and it's cold. I've tried the high and low settings with and without "CoolJet" (it's like a turbo/afterburner where it vapourizes more water to make the air colder).
Tilting the unit to the left alleviates the noise and I get slightly better airflow.
I've vacuumed out the unit, made sure the water is where the water is supposed to be, made sure all the housing and hoses and parts are secure.
I currently have a couple of paperback books propping the unit so it tilts a little to the left.
Can anyone diagnose the source of the problem, if there is anything I can do to fix it myself, and if running the unit tilted to the left is going to be detrimental to it?
My guess is the coolant leak is adding up... if that's the case, is there any DIY coolant top-up methods, or if it's something that a repair shop can do without costing a leg in addition to an arm?
