Their "guarantee" is not honored. I am buying a house where they repaired the AC for a price tag of $3800 for the seller less than 6 months ago. It failed the home inspection and they WILL NOT honor their supposed guarantee by even looking at it. If you had honored your own guarantee you would have gained me as a customer, never mind the former owner. As is, I will find someone else to follow up on the AC and you lose a potential customer and presumably the former owner will not be happy to have spent $3800 for nothing but you can take that up with him. I will not be giving you a chance for my business in the future.
