mid july my a/c unit froze up. .called American homeshield for service. Contractor came out and said he couldn't do any thing while it was frozen. said he would return later when it was thawed. Didn't show. called the contractor and was given another appointment. two more days. Then he couldn't charge it up, and after a call to "the boss", he said the compressor was bad. the parts were not available for a week. when the compressor was installed, it still wouldn't charge. after a call to "the boss" he said the coil was bad. another week. then homeshield called to tell me that there were out of pocket expenses. $840 this is to modify the duct, the drain pan, install a secondary drain pan, and an armi flex tube. Aren't these things part of installation?
