An HVAC Technician installs, services and repairs the plant that heats, cools and ventilates a building, from split systems and heat pumps to air handling units, chillers and their controls. The diagnostic core of the role is the refrigeration circuit, where readings have to be interpreted together rather than one at a time: pressures, superheat, subcooling, airflow and electrical draw each mean little alone. Work is seasonal and often reactive, with breakdown demand spiking exactly when the plant is under most load, so the ability to prioritise calls and give an honest assessment on site matters commercially. Refrigerant handling is regulated in most countries and the certification regime differs by jurisdiction and changes over time, so confirm the current local requirement before advertising. Hire for systematic diagnosis, clean brazing and accurate service records.
A technician who services split systems and small packaged units all day is not automatically comfortable on a chiller or a large air handling unit, and the reverse is also true. Name the plant types the role covers in the advert and ask candidates which of them they have worked on unsupervised and how recently. This avoids the common failure where a technically strong candidate is hired and then cannot work half the portfolio. It also lets you hire deliberately for a gap rather than for a general title.
Anyone can name superheat and subcooling. Ask instead for a system that was not cooling properly and follow how they narrowed it down: what they measured first, what the combination of readings told them, what they ruled out, and how they confirmed it before ordering parts. Then ask about a time they were wrong and what the actual cause turned out to be. Technicians who reach for a refrigerant top up as the default answer are expensive, because a system that needs gas has a leak somebody has to find.
Refrigerant handling is regulated in most countries, but the certification categories, who administers them and what each permits differ by jurisdiction and are periodically revised. Describe the requirement as the category of handling certification valid where the work takes place, then check the candidate's status directly with the issuing scheme and confirm the expiry. Do not name a specific certificate as universally required. Keep a record of the verification, since refrigerant logs and technician credentials are both subject to inspection in many markets.
Breakdown demand peaks predictably with weather, and that is the worst moment to start recruiting, because every competitor is doing the same and candidates hold several offers. Run recruitment in the shoulder season, keep a warm list of previously interested technicians, and be ready to move from application to offer within days when someone strong appears. Where the role includes an on call rota, state how often it comes round and how it is paid in the advert, because that detail decides more applications than the salary line does.
Service companies hire against contract wins and seasonal load, so the pipeline needs to survive between vacancies. Pitch N Hire's applicant tracking system stores previous applicants with the plant types they have worked on, their certification category and their expiry dates, so the next opening starts from a searchable list rather than an advert. Structured questions filter out applicants without valid handling certification before anyone reads a CV. Service managers who are out with engineers most of the week can review, comment and book interviews from a phone, which is when these decisions realistically get made.
