    HVAC basic interview questions.

    Hi

    I'm looking to hire a tech that has at least 3 years experience and i'd like to know if anyone out there has a set of questions that someone with three years experience should have the answers to. Any other advice would be appreciated.

    Thanks in advance

    Why are you set on 3 years experience? I believe continuing education is as important as anything. I would ask if they are taking any current training, or planning too, or what is the most recent training they have. I am new to this field, but I know of several "techs" with more than 3 years experience that I would not feel confident having represent my company. I guess it matters how they have spent those 3 years. Good luck.

    It's not necessarily a question answer thing. Make sure the exp. Is there, real world not tech school or 2 years as a helper and 1 as a tech.

    Verify when certs. Were aquired and ask about recent schooling and study. A good tech shouldn't be afraid to jump right in and should be able to demonstrate his skills without hesitation.

    Asking technical questions doesn't hurt but they need to be able to perform.

    Just my 2 cents

    1. how do you pump down a condensor
    2. how do you do a triple evac
    3. how do you check the charge on a unit
    4. what is Ohms law
    5. how many amps can a 2 phase 10 amp wire (trick question shows humor)
    6. what is the first thing you check on a service call
    7. how do you use a amp meter
    8. If you had a failed 35ohm 370volt cap could you use a 40ohm 440 cap
    9. do you mind GPS on the service van

    those are what i would ask a 3 year tech

    Are you trying to find out if the tech gives a yes or no answer to querstion #8?

    ...or if he says that caps are not rated in "ohms?"

    When you interview a prospective employee, you get a feel for them and there experience. I would (and have) sent them out with a mechanic to evaluate there skills. I do not look so much for what the know, but their ability to pick up knowledge and if they take advice and constructive criticism without getting pissed at the person giving it.
    I also look for the knowledge of tools, and how to use them properly, and how they take care of their own tools.

    One question you might ask: "At what point in a service call do you call the system manufacturer's Tech-support?"
