Does the saying “when you know, you know” apply to hiring the best HVAC Technician for your business? Maybe!
But the true evaluation comes during their interview and the questions you ask them.
Asking the right questions to determine if the candidate is not only skilled technically, but communicates exceptionally can be the difference between hiring a good technician and a GREAT one that you’re excited to have in the office and confidently send out in the field to your customers.
The interview process can be rough for HVAC business owners to get a good gauge on an interviewee, especially during the early days of hiring your first employees.
That’s why we surveyed the top HVAC businesses in the country and compiled the interview questions they ask their potential technicians into this ultimate guide.
In this post, we’ll provide 100 examples of the best questions to ask in an HVAC technician interview and break down the different skill categories you should be evaluating them on.
Get a real gauge on how your newbie will perform technically, communicate with customers and your office staff, handle difficult situations, and will invest themselves in the growth of your company by asking a variety of both standard and out-of-the box questions.
Start your interview off with basic “getting-to-know-you” questions. This eases both you and the interviewee into the interview without getting too technical too fast. Questions like this can uncover the background, personality traits, company culture fit and goals of the tech you’re interviewing.
Examples of general interview questions to ask an HVAC technician
1. Why did you get into the trade?
This is an interesting question that can give you a lot of insight about their motivations and interests. It is also a good one to start the interview with to get the conversation started.
2. Why are you available or looking at new opportunities?
Did they just get fired, do they hate their boss, do they need more money, a different shift, closer to home etc. Their motivations for making a move are important and can be a good indication if they will be a long term fit with you.
3. What do you know about our company?
Did they do some research on you prior to interviewing? If so that is a good sign that they are serious. If not it is an indication that they just need a job and may not care who it is with.
4. Why do you want to work with us?
This gives you a good idea of not only their motivations but what your selling features are to other mechanics for future interviews.
5. What in your previous experience and/or training makes you feel you would be a good fit for us?
6. Tell me about a time that you delivered more than what a customer or supervisor expected and how you accomplished the task.
Do they do the bare minimum or go above and beyond?
7. Your supervisor asked you to complete a task of which you do not have any understanding or personal knowledge. How can you assure your success?
You want to see if they are comfortable asking questions when they don’t know for sure how to complete a task or if they would pretend they knew how and hacked whatever it is together.
8. How do you see yourself as a customer advocate – constantly working to achieve better results for the customer in a way that fits organizational goals?
In what ways will they ensure customer satisfaction?
9. Tell me about your personal use of technology, and how that can translate to helping you do your job more effectively.
The HVAC trade has evolved to include technology with materials on the job site and also in the office to improve dispatching and job completion efficiency and organization. Are they able to learn new softwares that organize your business like Housecall Pro or will they end up taking up more of your precious time training them on how to use an app?
10. What can you do for us that other candidates cannot?
Similar to question #5
11. What makes you want to come to work every day?
This shows you who or what motivate them every day. Is it because they love the trade and they want to grow their career, put food on the table for their family or are they just in it for the money?
12. What is your dream job?
This helps you understand what their long term goals might be. If it is not in HVAC, make sure to ask them why they are applying for this job when its not their “dream job” per say.
13. Do you prefer to work alone or with others?
Understanding how they work best will help you picture how they will work with you and your current team if you have one.
14. Describe yourself in three words?
Shows you what they think of themselves. Don’t be afraid to dig deeper after they answer and follow up with “why do you think each of those words describe you?”
15. How would your friends/ family/ former boss describe you?
These words should be different from how they describe themselves because the people closest to us often see our skills and personality in a different way than we do.
16. How do you keep each member of your team involved and motivated?
This shows you their leadership skills and potential.
Technical HVAC questions to ask
You obviously want your new hire to know their stuff. This includes different types of services, parts, and most importantly how they relay information to customers in a way they understand.
Use the questions below in addition to any other specific mechanical questions you have in your company.
Examples of technical interview questions to ask an HVAC technician:

It is a red flag if they answer this question with “nothing” because that means they don’t think they have anything they can work on or learn which we all know is never true especially in HVAC.
28. How do you prioritize your work?
The answer to this question shows you how they sort through information and projects in their head. Do they start with the hardest task first? Do they knock out any administrative work they need to do?

How far are they willing to go to solve a problem and if they do deem something unfixable, do they create an alternative solution?

Situational and soft skill HVAC interview questions
Understanding your potential newbie’s soft skills and how your potential newbie thinks through different situations is equally as important to their technical skilled knowledge.
Soft skills are non technical skills that relate to how your future tech works including how they communicate with customers and other employees, how they problem solve and manage their work.
Situational and soft skill interview questions are a fantastic opportunity to get an idea how your potential tech thinks through past experiences and future scenarios. When listening to these answers, pay close attention to how they explain the situation and articulate their learnings.
Examples of situational/soft skill interview questions to ask an HVAC technician:

Don’t ask, have you ever sacrificed safety for speed, they will almost always say no, assume they have and see what they say.
43. Tell me about your favorite supervisor or manager that you have worked for, what made them great?
This will give you a good idea of what management style they respond best to, does this match up with your shops supervisor?

90. Why did you choose this Career path and what can you do to make this organization successful?
91. What are you looking for in means of company culture at your company?
Wrap up questions
These are the logistical, “next-step” questions. End your interview with these wrap up questions to set expectations for both you and your potential technician for things like their availability and start date.
If you already know you’re not going to hire this person, you can skip out on these if you want.
Examples of situational/soft skill interview questions to ask an HVAC technician:
92. What are your wage expectations?
93. What shifts are you available for and what is your preferred shift?
94. If selected, when are you available to start?
If they are currently working you want them to say 2 weeks, if they say immediately that likely means they are not going to give their company notice which is a red flag. It may also just mean they know their company has a policy of not accepting notice and they could be available immediately.
95. Why did you leave your previous employers?
If they have routinely been terminated that is a red flag, if the same issue keeps coming up at multiple places that could also be a cause for concern.
96. Have you Ever Been Terminated From a Position Before?
97. Can you supply us with references?
Ask them to email them to you, this will give you an example of their written communication and ability to follow direction. You can also see how serious they are about the job based on how quickly they get the references to you.
98. Do you have a valid driver’s license?
99. Do you have a clean driving record?
100. Is there anything that was not covered on your resume or in this interview that you feel we need to know?
