/ Use them honestly
Keywords get you found. Proof gets you hired.
Mirror the job post's wording for skills you really have. If an HVAC technician post asks for HVAC and you've used it, say HVAC, in the post's spelling, and show where.
Mirror the job post's wording
If an HVAC technician post says "EPA 608 Universal", write "EPA 608 Universal", not a near-synonym — as long as it's accurate. Recruiters search for the post's exact term.
Only claim what you can back up
Expect to be asked about every term you list. If you couldn't spend two minutes on HVAC — what you did and what changed — leave it out.
Show it in a bullet
A skills list says you know Heat pumps. A bullet like the one under HVAC Service Technician in the example above shows what you did with it.
No stuffing, no hidden text
Repeating a word or hiding keywords in white text doesn't make you a better match. A person reads the resume in the end.

How many keywords should an HVAC technician resume have?
There's no magic number. Andre's sample resume uses all 19 terms on this page, because each one fit that job. Cover what your post asks for that you can back up, each where it fits; repeating a keyword doesn't help.
Should I copy keywords exactly from the job post?
Use the post's wording for skills you really have. If an HVAC technician post says "HVAC", write "HVAC" rather than a synonym, so a recruiter searching for that term finds you. Don't add skills you don't have just because the post lists them.
Where should keywords go on my resume?
In your summary, a short skills section and, above all, the bullets under each job, where you show what you did with the skill. In Andre's sample, HVAC, EPA 608 Universal and NATE are in the summary and Heat pumps shows up in a bullet under HVAC Service Technician. Plain text in the body of the page is easiest for applicant tracking systems to read.
Which tools should I list on an HVAC technician resume?
The ones you've used and the post mentions. Common ones in HVAC technician posts include ServiceTitan. Name the tool in the bullet where you used it, not only in the skills list.
How should I list EPA 608 Universal and NATE on my resume?
Spell them the way the job post does, and include both the abbreviation and the full name if you have room. Put licenses and certifications in their own section or next to your education, and only list ones that are current.
