I bought my first house a little over two months ago. During the home inspection the heat pump was old but operational, and we had the seller purchase a home warranty. Our heat pump ran for half a month as an air conditioner and worked for about a month and a half as a heater but just recently conked out. We had the home warranty people send out a repairman and he said the unit is completely dead, and that the home warranty company might try to say that it was a preexisting condition. What should I do,? We just covered a down payment and do not have the cash to pay for a whole new heating unit.
