should I upgrade?

There aren't any moving parts or oiled parts as you would have in say a sewing machine that sat in the closet.

I beg to differ. I've taken apart a few of my machines when they died and they all do have at least one moving part - the blower! But like the Mb said there's nothing in them that a user could service.

wouldn't be the first time I'd heard of someone oiling a bearing....

Oil? I thought you were supposed to clean and polish them, and ultra sonic carbon tech clean would do wonders for an old bearing (j/k)

Was diagnosed with OSA in 2002, bought a Respironics Remstar Pro C-Flex with Breeze nasal pillows. Broke the Breeze in 2005 and stopped using it for years. Bought a new strap-on nasal pillow rig 6 months ago and started using system again. Has 4300 hours on it. I never heat the air, using an inline water tank that I sometimes even put chilled water in for comfort.

Should I be getting that cpap serviced in some way? Or, being 14 years old, should I be looking at getting something newer with spiffy new features that have become available in the last 14 years?

Although your machine is old and outdated, it has slightly more than the equivalent of one-year's use in hours. I seem many of these older machines retired near 20,000 hours. There is nothing to service inside the blower unit. A newer machine would give you better access to therapy data and probably some additional comfort features, but may not be very different in effectiveness. It might however, motivate you to use and optimize the machine.

If it's covered by insurance, or you see a good deal on an upgraded machine, go for it! I think having a backup could be important as a machine get old.
