Panasonic Inverted Ducted S-140PE1R5A / U-140PE1R5A (14.0kW) Questions & Answers

I am not sure about that you may need to check with installer, mine is Ali 450m block it makes noise

Hello Maltese12, I'm unable to offer you advice as my unit is new and I havent needed to yet. I expect that I will get it done at the next service

I assume based on the size of the Unit, you may have a double fan (top/bottom). Regardless, you will need to make sure that the unit, is free from obstruction all the way around. Make sure that there is plenty of airflow when the unit is operating. The fins that are located all the way around the back and side, need to be clear of any obstructions. There are good videos (youtube) on how to clean external units and keep the fins clear/clean and free from obstruction. Keep the area around the unit free of any dust etc, as this will be swept up in the wind, or while it is operating and get into the fins. Once the fins are blocked you restrict the airflow into the outside unit. Once the restriction of air through the fins are caused - your external unit - will be running in-efficiently. If you want more information please post.

Yep well you picked a good time to ask because it's been hot as hell around here and our Panasonic has been set to 24 degrees constantly running day and night, sometimes switching to dehumidify only at night - what a system, it really is incredible and our house is a haven we don't want to leave!.
I seriously can't fault it, efficient, economical and quiet too.
We are having it serviced this coming week and the cost is only $250 - happy with that.
The comfort this system provides during summer is priceless - go for it!!

Thanks so much for your detailed response! We are definitely going with this one

Still very happy just remember to clean the filter regularly

I have a 10kW unit that's about 4 years old now. It's located right outside our lounge window and I hardly notice it even with the window open. Obviously it's loudest when it's running hard, but even then it's not too bad (I don't notice it with the window closed). It did have a rattle in one of the panels, but that was easily fixed with a small piece of foam.

I have a 12kw unit next to the master bedroom it has never kept anyone in the house awake .in fact i have to go outside and stand next to the unit to see if it's running .
