America Home Shield RIP OFF, Internet

My hearing impaired daughter, a single mom purchased America Home Shield Warranty only to find it is not worth having.  Her AC went out in July, August and then September.  AHS is claiming that her 2006 home must be brought up to the 2009 codes before they can replace the leaking coil on the AC system.  This is a new home and she is not paying $716.00 to put in a 3" larger drip pan,  drain modification, hanging kit and float switch.  This repair does not require a permit and we I contacted the agency that writes the codes they indicated it was not necessary unless we were getting a permit for construction.  This is a way for the AC Company, STAR HOME COMFORT, to pad their pockets and lower the cost to AHS. I have asked for a copy or number on each code and they will not give me this information yet they want her to pay for the repairs.  Both companies are scam artist.
