Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you had a piece of HVAC equipment fail during production and you had to get it running again fast.
What they are checking: how they perform under pressure on emergency breakdowns and whether they can make sound judgment calls quickly
Tell me about a preventative maintenance program you've been part of. What was your role in keeping it on track?
What they are checking: whether they see PM as routine paperwork or genuinely engage with reliability practices
Describe a situation where you had to teach a less experienced technician or coworker how to do something.
What they are checking: willingness to mentor and share ownership, which the posting explicitly asks for
Tell me about a time you were part of a root cause analysis after an equipment failure. What was your contribution?
What they are checking: ability to participate meaningfully in group problem solving, not just fix and move on
What kind of environment have you worked in before, industrial, hospital, manufacturing, and how did the pace or safety expectations differ from a typical commercial HVAC job?
What they are checking: whether their past environment matches the demands of a manufacturing plant setting
What would you do
Say a chiller alarms out at 2am and you're the only tech on site. Walk me through how you'd approach diagnosing it.
What they are checking: structured troubleshooting process and comfort working independently without backup
If you found a system control setting way outside its normal range, but the equipment seemed to be running fine, what would you do?
What they are checking: judgment around when to intervene versus escalate, and respect for process over shortcuts
How would you handle a schedule change that moved you off a project you had ownership of and onto a different shift or task with little notice?
What they are checking: flexibility and attitude toward the shifting assignments the role requires
This job involves lifting up to 40 pounds, climbing stairs, working overhead, and sometimes outside. How have you managed the physical demands of HVAC work over a full shift?
What they are checking: realistic self-assessment of physical readiness for the job's ergonomic demands
About the work
Walk me through your EPA 608 and refrigerant license background, and tell me about the range of equipment you've worked on, things like rooftop air handling units, chillers, or DX units.
What they are checking: whether the required licenses are current and backed by real hands-on breadth across equipment types
What's your experience with steam and condensate systems, and have you done any pipefitting work?
What they are checking: depth in the utility side of the role beyond straight HVAC, since the posting explicitly calls this out
Can you read an electrical schematic, and tell me about a time you traced an electrical fault on HVAC equipment using one.
What they are checking: real electrical troubleshooting skill versus just familiarity with the concept
Have you worked with Reliability Centered Maintenance or similar programs? What did that look like day to day?
What they are checking: exposure to RCM concepts, which the posting lists as a preferred differentiator
Tell me about your experience with fire suppression or fire protection systems, if any.
What they are checking: coverage of a required-adjacent skill area not central to HVAC training but explicitly listed
