Last year I purchased a carrier AC unit and 10-year service plan (paid extra $600) from Service America. Last Friday (06/24/16) my AC unit stopped working and I called the customer care. They scheduled a service on 06/24/16 Tuesday. ( They asked me $200 for next day service). One technician came on Tuesday and he told me he fixed everything. After two hours he left from here my unit failed again and I called the customer care immediately and they scheduled next service for next Friday (I begged them to next day service). They never give a same day or next day service. We are (2 kids- 2 and 5 years old) living in 85-90 degrees, from last Friday. I don t know when they can fix it?
