How to hire HVAC technicians.
What each commercial HVAC seat pays, what a real search produced, where technicians who are not looking actually hear about work, and how to test diagnostic reasoning before you hand over a truck.
The HVAC hire that goes wrong is rarely the technician without the certificate. It is the one who cannot reason through a fault they have not seen before, or the strong technician put into a seat that needs a different skill. Each seat below fails in its own way, and the interview questions further down are built to catch it.
What each HVAC seat pays, and the hire that goes wrong
The bar is our mid-experience band, built from our own engagement history. The dark marker is the federal median for the closest title (BLS, May 2025). Every bar uses one scale, $35k to $150k.
Hiring on EPA 608 and years of experience without testing diagnostic reasoning. The certification is a floor, not a signal, and residential-heavy experience transfers badly to rooftop and chiller work.
Strong service technicians move to lead tech, then service manager, or sideways into controls, which usually pays better sooner.
The service technician questionScreening this seat on programming or on mechanical experience alone. The scarce combination is both, and it can come from a controls contractor, an integrator or a mechanical shop, so test both halves.
Controls technicians move to commissioning agent, controls project manager, or independent integrator - the last of which is why they are hard to keep.
The controls technician questionHiring on project size alone. A manager who ran one $20M job may have run one schedule; a manager who ran twelve $2M jobs has run twelve buyouts and twelve closeouts.
Project managers move to senior PM, operations manager, or into preconstruction and estimating.
The project manager questionPromoting the best technician into the seat. Field strength does not predict dispatch discipline, and the department loses its best diagnostician in the process.
Service managers move to operations manager or general manager, and in smaller contractors to owner.
The service manager questionFederal data files service and install technicians under one title, with a median of $61,010, so it cannot tell a strong commercial diagnostician from a production installer. Price the seat against what the technician earns now rather than against the federal figure. Experience, region, union status and the mix of service and install work all move these figures, and our salary calculator adjusts for the first two.
A technician who already has a truck compares the whole job rather than the hourly rate, so write out the offer before the first call: the take-home truck, the on-call rotation and what it pays, overtime, the tool allowance, and how far the territory runs.
Good technicians come from a bench, not a posting
The client kept one search open and made four hires from it over about seven months. The most recent had been in our database for close to three years and was re-engaged when the timing was right, which is how strong technicians tend to move: when something changes for them, not when you post.
A certified commercial service technician in Houston was hired 16 days from first contact.
Read the case studyReal searches rather than a benchmark, but they show why the technician you hire next year is someone you should be talking to now.
Have us run the searchHow to reach a technician who is not looking
Define the seat by the equipment
Before anyone gets a call, write down whether the seat is service, install or controls, the equipment it runs on, such as rooftop units, chillers, VRF, boilers or a particular controls platform, the building types, and the on-call rotation. A service technician and an installer are different hires, and a written definition is what lets a source tell you who fits.
Start with your own technicians
Your technicians know who in your market is good and who is unhappy, because they trained with them, worked beside them or followed them on a job. Pay a referral bonus once the new hire has stayed long enough to matter, so the referral is about fit rather than a quick payout. Technicians who left you on good terms are worth a call too, since they already know your trucks, your customers and your paperwork.
Make the first call short and specific
A service technician is on calls all day and cannot talk with a customer standing next to them, so text first and call after the last call of the day. Say who you are, how you got the name, and what the truck, rotation and range look like in the first minute, since someone with a stable job has no reason to stay on the phone for less. Then ask what they would need to see before they would consider a move.
Plan for the counteroffer
Ask before the offer goes out what the technician will do when their employer counters, and whether they have already asked for what you are offering, such as a lighter rotation or a closer territory. Ask early for a copy of any non-compete or non-solicit they signed and have your counsel read it, since it can change the start date or the customers they are allowed to serve.
Start before the season needs the person
Our Hiring Index times every search from first contact with the candidate to the hire. That clock leaves out the time before a search begins and the technician's notice period, which is why the search has to start before the cooling or heating season puts pressure on the schedule. Our guide to recruiting technicians who are not job hunting goes further on outreach.
Test reasoning with a real fault, not a certificate
Each seat gets one scenario here, and our HVAC hiring kit has the full set for each role.
A strong technician treats it as load and ambient dependent rather than random, and separates refrigeration causes, such as high head pressure from a dirty or recirculating condenser, a failing condenser fan or an overcharge, from control causes like a sensor reading the wrong thing or a safety tripping and resetting. They take readings while it is actually faulting, by leaving a data logger or pulling the BAS trends rather than paying for a second truck roll, instead of diagnosing it cold in the morning.
Follow up: What readings do you take while it is short-cycling, and what would tell you it is a control problem rather than a refrigeration one?
A strong installer flows dry nitrogen through the pipe while brazing, at a trickle rather than a blast, so no oxide scale forms inside the joint. They also know the consequence is not cosmetic, because that scale breaks loose later, plugs the filter-drier or the metering device, contaminates the oil and kills a compressor months after the crew has gone.
Follow up: How do you know the nitrogen is actually flowing through the joint you are brazing and not out the nearest open end?
Look for a specific sequence rather than a general complaint: simultaneous heating and cooling, a static pressure reset that was never implemented, or a sequence copied from a different unit. The strongest answers also say how the change was agreed and recorded with the engineer, rather than quietly corrected in the field.
Follow up: Who approved the change, and where is it written down now?
A strong project manager confirms the new date in writing from the manufacturer rather than a verbal from a rep, then works out what it actually blocks: startup, commissioning, temporary cooling and the certificate of occupancy. They tell the general contractor the same day with the impact and the options, price temporary cooling if the date will not move, and start the time extension conversation before the float is gone.
Follow up: Who do you tell first, and what do you put in writing that same day?
A strong manager gives a number and says how it was defined, because utilization means different things in different shops. Then they name the lever and what it was worth, whether that was a dispatch change, truck stock that cut return trips, better call screening or planned maintenance used to fill the gaps.
Follow up: What was it before, and over what period did it move?
A technician who already has a truck needs only one reason to stay
A rotation nobody can explain, a truck policy that changes at the offer, a range that moves late and an offer that sits in approval for a week can each provide that reason. The range you gave on the first call has to hold, so be specific about the rotation, overtime, territory and whether the truck goes home. Introduce the service manager they would report to and the lead they would ride with, and say what training comes next, because a path into controls or a senior role is often what moves someone who is already paid well.
What to verify before the first day
Common questions
How long does it take to hire a commercial HVAC technician?
In our internal data, most commercial HVAC hires happen within four weeks of first contact with the candidate. That clock leaves out the time before a search begins and the technician's notice period, so start before the season that needs the extra truck.
What should you pay a commercial HVAC technician?
The federal median for HVAC mechanics and installers is $61,010 (BLS, May 2025). Our mid-experience band for a commercial service technician is $48,000 to $72,000, and on-call pay, the truck, overtime and region all move what a technician will accept.
Can a residential HVAC technician do commercial work?
Some can, but residential-heavy experience transfers badly to rooftop and chiller work, so test diagnostic reasoning on commercial equipment rather than assuming it carries over.
Is EPA 608 certification required to hire an HVAC technician?
It is required for anyone who services equipment that could release refrigerant, so it is a minimum rather than a sign of skill. Confirm the type they hold matches the equipment they will work on.
