Info in the Property Condition Disclosure Statement is incorrect

[Brien Ables]

I am purchasing a property and have come to find out that the info in the property condition disclosure statement is incorrect.  The seller has the HVAC system listed at 6 years old, and I have found out that it is 18 years old.  I informed the realtor and she said the seller said he mistakenly wrote 6 years on the outside unit, but the inside unit was 6 years old.  Well, I went in the attic, got the serial number and checked the age of that unit.  It also is 18 years old. The seller does not want to negotiate, because we agreed to a price below what he had listed and I already will have equity in the house.  Had I known the HVAC system was as old as it is, I would not have agreed to the price we agreed to.  I am wondering if I have any legal action I can take with this, since the seller pretty much falsified the PCDS.
