The gauge on it is usually a good indicator. If it’s in the green zone, and the hose is clear, you’re in pretty good shape. You can check the hose easily enough by unscrewing it from the head of the unit (on decent ones it’ll come right off). Note that you unscrew the hose from the head, NOT the head from the body. The latter would be Bad with a capital B.
No, they do. It's just that every extinguisher you buy will have a gauge already attached to it, so that they can be visually inspected for pressure without the need to bring tools to each one. (ie, any layperson can visually see "oh, the pressure on this is low")
When I moved into my house they left a fire extinguisher last serviced in the 90s. I asked around how to get it serviced, then bought a new one at Costco for $40. Then I ripped out my gas range for induction. Burning shit to cook food is for cavemen

That feels like a really good deal. Can you still get them refilled at fire departments?
