Closing relationship with PM and holding accountable

[Mike Craig]

We are terminating our relationship with our current PM and have some issues with the work they had done in our absence.  They managed this property for us while we were on the other side of the country for two years.  They had their HVAC vendor come out multiple times and finally insisted on replacing the air handlers to fix over freezing issues.  The work was done extremely slow and now that we have been back to see it the hvac closet it full of trash and debris from their work and the unit is still not performing as it did for the 6 years before we rented it out. They also had random shotty repairs performed around the house without out consult and they are terrible and will need to be replaced.  Do I have an leg to stand on from a legal point of view holding the PM and their people accountable for this B rate work?  Can I insist on compensation or better repair?
