Very disappointed.  Fan was professionally installed and worked for a week then stopped.  We contacted company and went through a newer of potential fixes...no thing worked.  Rep said they would replace.  Gave me a claim number and asked if I could send invoice, which I did.  They indicated they would contact me in 48 hours.  Two weeks later no contact, I followed up with an email request with claim number and I got an email back asking me information previously provided.  Having spent this amount they should be more responsive.
