I had a Mitsubishi ducted split heat pump system installed about a year ago. It has never worked properly, the A/C is insufficient, the heating is erratic and its just a pain in the butt. It has been looked at by a mitsu rep who said they are working on a fix but that was months ago. It was installed correctly by the local HVAC company. I would like to have it removed and have a traditional heat pump installed, this one cost me almost $15k. Do any of you lawyers out there have any suggestions on how to get my money back? Do i sue the installer or Mitsubishi? Can i win? How much will it cost me if I dont win? Thanks
