homeowners replacement vs repair..how to file appeal claim

My air conditioning unit was damaged in a wind storm..the condenser was laying on it's side. Damage found on condenser coil and no Freon was present in the system. System ran post storm and oxidation was introduced into the Refrigeration circuit including the indoor coil was knocked over. My insurance company wants to repair instead of replacing..I have 3 estimates stating it needs to be replaced but the company that they sent out to investigate said it is repairable...what can I do to appeal or dispute this??? help please we are without air and its getting hot outside!! 8)
