Just moving back to Manhattan during one of the hottest months on record, I needed air conditioning in a BIG way. RCI was recommended by my Super as good on service/good on value. I purchased four top of the line Friedrich window a/c units from RCI (well over $4,000!) ...and had them installed by them as well. From the first moment there were issues with each unit...apparently Friedrich intends that every new unit need additional adjustment before working optimally. Then finally, the last unit sprang a leak - cooling absolutely nothing. After nearly a month of "parts not yet available" Friedrich would do nothing to fix my problem...but RCI stepped up and took care of me when Friedrich did not - in the words of RCI's owner, "you are my customer...my relationship is with you and it is important to me that you are happy".
And so on their own dime they replaced my unit. I cannot say enough good things about the fact that they were there for me. In short...go to RCI!
