We are considering buying a United heavy duty commercial freezer(Model # UCF200/H). The freezer is 2 years old…looks in great condition…but I can’t find any information about who manufactures United. Is this a quality freezer and will I have problems getting it serviced if needed? I am told that the original owners bought the freezer from American Frozen Foods. I contacted this company and they said someone else manufacturers the freezer for them but I could not get any more information.
