Just a warning about this company's air conditioning units. Instructions for the use of air conditioning systems don't come with the delivery person (he/she knows nothing about it and as well they may not come to the instructed door drop off ), nor does he point out that there is a little picture diagram (that I probably wouldn't have understood anyway), nor does anyone tell you that you need to add water when you've called them three times before the day of the event and talked to the service dept about how it works. Yes, I guess I will take responsibility for not calling them on the day to make sure I was doing it correctly but I thought I was smart enough to set the few simple buttons on the machine...guess I wasn't. Nope, didn't know I had to put water in it ...and even if I had known this I did not have a garden hose at a rented church hall to do this. Our church hall was stifling hot when we got there that night and elderly people in the community suffered greatly. And I guess it's not surprising that Susan the owner will not compensate me for this even a little bit. We are a small non-profit organization so our business doesn't really matter...a common thread in today's business world.
