I purchased a Haier Commercial Cool air conditioner 03/2010. By June 2010 it was not working. I conducted all the trouble shooting options to no avail. The thing just will not turn on. I contacted costumer service. After a brief run around, I was finally given a ticked number and date for servicing. Well, that sounds great and all, however, the technician never showed up. I called again only to be told their records indicate my unit was serviced. Now I am stuck between a rock and hard place. I can't get a refund from the store that sold it to me and the company is saying my issue was dealt with. At this pint I have a giant $400.00 paperweight!!!
