I bought my first house a little over 2 months ago. During the home inspection the heat pump was old but operational. We had the seller purchase a Home Warranty. Our heat pump ran for a 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 repair man and he said the unit is completely dead, however 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.
