Hi, and the answer is no. This system is a sealed hermetic a/c unit, and does not require you to charge the unit, only if it develops a leak in a coil, copper line, or a line has rubbed through causing it to leak. If it is cooling good, your freon level should be fine. It doesn't hurt to go on top in the summer or before it gets hot, remove the cover and take your garden hose and kill power. Now, wash the coil out real good. They get very dirty and cause the pressures in the system to get real high and the unit will not cool like it should. This is about all you can do, but its very important. Keeping the indoor filter foam clean is also good, but no you don't need to charge it on a regular basis, only if you have a leak in the unit. Please don't forget to rate me as I know you will be kind. Please let me know if you have any problems with your unit, and I will be happy to help you out.
Sincerely,

the fan motor bearings need lub....the shaft has a tiny access hole to put some oil into. because the fan shaft is slowing down, it is putting more strain on the voltage current, and eventually the internal breaker shuts down the ac........plus your condenser is not getting enough air accross it, compressor heats up, and it too will shut the unit down......older units have to be oiled every year, and eventually it too will fail, and a new blower motor assembly is needed or replace the ac unit.....blower motor units are around $130....now you install it or pay to have it done at around another $150 labor,,,,,try yourself, if it fails then call the tech........let me know ..ray..yyzazz@ao.com
