HVAC Technician Resume Bullet Points
17 examples, each shown weak and strong
A strong HVAC bullet says whether you work residential or commercial, service or install, and backs it with calls, installs and callbacks. Put your EPA 608 type near the top, then show that you fix it right the first time and leave the customer ready to renew.
How to use these
- Every [X%], [N] and [$X] is a blank for your own figure. Fill it from your records, or a careful estimate you could explain in an interview. If you have no number, describe the result in words.
- Only use a bullet for work you actually did. Change the details until it describes your job, not this page.
- The ticks are three plain checks done in code: it opens with an action verb, it has a number, and it says what changed. Strong bullets pass all three; weak ones miss at least one.
