You delivery personnel were wonderful. They were supposed to call before they left the warehouse with a time approximation and they did!! They were also going to call about 30 minutes before delivery, but instead they called to say they were running late. Something like that NEVER happens. I gave them my address, quick directions, and in 30 minutes they arrived. Very helpful along with the fact I didn't realize I would get a new venting. Thank you delivery for keeping me informed...very unusual in today's world.
