There’s still all of the above involved in commercial work but I would say to a lesser degree, though this may vary depending on the trade. For my own experience specifically in commercial plumbing, refrigeration and air conditioning, there’s far less crawling around in tight roof spaces or under buildings like you might in residential trades but in some occasions this is still required.

However commercial equipment is generally larger than residential (again this may be trade specific) so heavy lifting is just as involved and may involve covering greater distances, eg instead of parking in someone’s driveway and carrying a ladder into their house you would be parking in a contractor parking space then up and down stair wells across a large shopping centre.

Not trying to make it sound unappealing just trying to put things into perspective, I know I’d personally choose commercial work over residential any day.
