Hi all! Im new here and new to the world of ptac's. I'm in my 4th month as the maintenance coordinator at a Sunrise assisted living facility and so far the biggest challenge has been these freakin ptac's freezing or over-flowing on the carpet
I have gotten pretty good at changing out the control boards but there are some units that want to frost over or ice up. I'm just wondering what would be the cause nd if it is worth trying to fix being that they are a 'sealed' unit
any advise would be appreciated!
