Yah, but heat pumps have compressors too. I'm not sure what failure modes are the most concerning. The pressure vessels probably have some max number of load/unload cycles in them for instance.

Most refrigerators have compressor (exists mostly mobile schemes, powered by heat, but anyway they have pressure inside).

From conditioners installers, I've hear, they mostly have issues with external connections, but near none with what made on big enterprise.

So window conditioners, or mobile conditioners, or heavy duty industrial conditioners with salt water as working liquid, are extremely reliable.

Same thing with heat pumps - if it is possible, to make all pipes with high pressure on enterprise, there will be no problems (reliability 3 Sigmas usually). Only potentially problematic, what done at fields.
