These questions are directed to the Maintenance people out there who have in operation one of these Variable Refrigerant Drive systems.

I would like to know if you have any maintenance issues, like easy or difficult to change air filters, Blower motor issues, etc. Are your filters "off the shelf" sizes or "special order".

If you have your system controlled by a BAS, do you use night set back/set up during unoccupied times. And how well does it recover temperature when occupied.
