Evaporative coolers function by sucking the hot dry air through filter pads of aspen or plastic mesh that are saturated with water that circulates via a pump in the cooler sump.They need twice yearly maintenance to even achieve their 5-10 year lifespan. 

Get the water out, dry it out and see if it'll run.

HI - I'm considering buying a small condo in Manhattan but the window is facing multiple unidentified vents, seller told me it's all AC vents from 1 restaurant and 1 dry cleaner business on the ground floor. 

Hard time finding contractors to do the work, so that has caused us to have lots of vacancies in houses awaiting a plumber/electrician/dry wall contractor, etc.

I have a lot of family members who work in the construction field from Tile ( a lot of those ) , framing , foundation , roofing ,painting, and dry walls.

We are in talks to take on a 25% partner for a decent sum that would handle most of our bridge needs but it's only early stages and these things dry up and go away often, so I need to keep pushing on all fronts. 

I'll notice weeds and dry spots and address them.   

Rainfall is minimal, averaging less than a third of an inch, making it a relatively dry month.
