That they deliver and walk down to the basement to put the salt in the unit. I'm no longer able to do this due to age and medical issues. I like that they knock and announce themselves, then just come in. I work from home. I often times can't be interrupted to come to the door. Sometimes I don't hear them. They also backed off on the the quantity when they realized my consumption decreased after my mom died.
I was having problems with my softener, not working correctly. They came right out and put a new panel on. Got it working. They were friendly, clean and quick thanks Culligan.
