What are the complete sets of tools an HVAC engineer or technician should have?

This question sounds like you already know the answer. I would imagine it wil vary based on what field they primarily will be working in. This is off the top of my head so there may be a few items I miss. Comment edits of items I have overlooked.

Basic hand tools;
slotted and Philips screw drivers
small screw driver set.
nut drivers (SAE most work) 1/4–3/4”
needle nose pliers (I like to have standard and 45 deg angle)
lineman's pliers
hand crimpers (electrician not the cheap one either - they suck)
side cuts
box and open end wrenches (include a few sizes in “dog bone”)
adjustable wrenches (6”-12 or 14”)
pipe wrenches (various sizes)
hammers various
garden sprayer

An engineer and a technician are two completely different career fields requiring different educations and who do different tasks. 

Most engineers will use very few hand tools in their careers. But they would need ink pens pencils calculators and perhaps a flash light if they go into the field to instruct a technician on how to solve a complex warranty task.So your list is meaningless, sorry. You are also at least dozens of tools short on your list for a technician. sockets, ratchets, flash lights, pocket or torpedo levels, vacuum guages, vacuum pumps, manometers, volt ohm meters, extension cords, drills, drill bits, caulk guns... the list just goes on and on and on.  Even simple items like a broom and dust pan to clean after you are finished have to be carried in your truck.

Elhigh is spot on in his answer and in his comment toward Steven. Steven is an idiot. The only one who believes Steven isn’t an idiot is Steven. His mother also knows he’s an idiot. 

As far as drivers, a standard 10 in 1 is usually good enough. Anything else you can use wrenches for or a small socket set. If you’re doing commercial, make sure you have an Allen for lieberts, a triangle key for Stulz and a small punch or screw driver to pull the pin on Data Aire switches.

Steven F, I dislike you because you’re an ignorant, arrogant ********. I would gladly put my knowledge and skills against yours any day. You are an idiot. If you want, I can tell you that to your face.

This IS NOT a question, and YOU are the least qualified to answer.
In fact, no one that believes there CAN BE a single correct answer is qualified to answer.

ehigh is again projecting HIS faults on me because he doesn't like me. The reason HE insists of proving is I am RIGHT more often than he is, precisely because I DON'T think I know everything. His answer actually EXPLICITLY agrees with everything I claims I am wrong about.

redstapler dislikes me because he KNOWS I am right more often than he is. He also contradicted himself in his claim he agrees with ehigh.

there are various consumables that you'll also need -- among them; mastic, fungus killer, electrical tape, spare sheet metal screws in multiple sizes and lengths, insulation board [you'll be making plenums], HVAC tape [aluminized], solder, aluminum cover for new hvac lines, screws and anchors for same, masonry drill bits [and battery powered drill to use them in], expanding cell foam sealant, J clips to secure the new HVAC lines to the building, spare filters in multiple sizes, and probably another couple of dozen that I've forgotten  -- oh, yes -- and a whopping lot of patience will be needed to deal with homeowners who ignore instructions and never service their units ever [until they stop working].  Hmm -- I left out stuff related to swamp coolers [if they're used in your area]. ...
