HVAC Install Technician (Commercial)
We place this role between $52,000 and $80,000 a year at mid experience, before overtime, bonus and on-call.
What the job actually is.
Sets and connects commercial equipment on new construction and replacement jobs: rooftop units, split systems, VRF branch controllers, ductwork and refrigerant piping. The job is production work against a schedule, with the quality of the brazing and the hangers determining whether the service department inherits a problem.
What this role pays.
That band is mid experience, built from our own engagement history. Experience and region move it - the salary calculator applies both.
The federal occupation this role reports under is Heating, Air Conditioning, and Refrigeration Mechanics and Installers (SOC 49-9021), May 2025. Nationally it reports a median of $61,010 , with the middle of the market between $40,050 and $95,210. BLS counts this job inside that occupation rather than publishing it separately, so the figures cover a slightly wider group than this exact title.

HVAC Install Technician (Commercial) vs HVAC Service Technician.
Install work is scheduled; service work is not. An install technician is placing and connecting new equipment on new construction or replacement, so the day is planned and the equipment type matters more than diagnostic speed: a crew that sets rooftop units all year is not automatically ready for a chiller or a VRF system, and that is what a client means when they ask for someone experienced. Both roles carry EPA 608 and both sit inside the same federal occupation, so the table below is the same table the service page prints.
HVAC Service Technician: what it pays and what the search takes
Credentials that move an offer.
- EPA 608
- Rooftop/Chiller/VRF
Licensing is a state question, not a national one. The HVAC & Mechanical hiring page carries the state-by-state position, and every market page names the authority for that state.
What separates a strong candidate.
Everyone who applies for this seat will claim the experience. These are the things that distinguish the people who have it, and the questions that find out.
What to look for
- Brazing with nitrogen purge described as routine rather than as a best practice they have heard of
- Has set equipment by crane and can talk about rigging and roof curb fit
- VRF experience named by manufacturer, because the commissioning differs
Questions that find out
- How do you purge a line set, and what happens downstream if you skip it? A strong answer Dry nitrogen flowing through the pipe while brazing, at a trickle rather than a blast, so no oxide scale forms on the inside of the joint. Knows the consequence is not cosmetic: that scale breaks loose later, plugs the filter-drier or the metering device, contaminates the oil, and kills a compressor months after the installer has gone.
- What do you check on a roof curb before the unit lands? A strong answer Level and square, the right curb for that unit rather than the one that was already there, flashing and counter-flashing intact, a continuous gasket, duct openings that line up with the unit rather than nearly, and the deck underneath sound. Checks before the crane arrives, not while the unit is hanging.
- Describe the last VRF system you installed - whose, how many indoor units, and who commissioned it? A strong answer Names the manufacturer, a real indoor unit count, and who did the commissioning, including whether they were there for it. Knows most VRF warranties depend on factory or certified startup. Someone who helped on one job will go vague on exactly these three details, which is why the question asks for all three.
- How do you support a long refrigerant line set on a roof run, and what fails when it is done badly? A strong answer Supports at the manufacturer spacing, on rails or blocks rather than lying on the membrane, with allowance for expansion, isolation from the structure, and UV-rated jacketing that birds and weather will not open up. Names the failures: sagging runs that trap oil, insulation that degrades and sweats, pipe that chafes through, and a roof leak nobody connects to the HVAC job.
- What is your pressure test and evacuation process, and what micron level do you pull to before charging? A strong answer Dry nitrogen to the manufacturer test pressure, held and recorded over time, then a deep vacuum measured with a micron gauge placed away from the pump. Isolates the pump and watches the decay rather than trusting the number at shutdown. Gives a target in the right range and, better, reads the shape of the rise: levelling off means moisture, climbing steadily means a leak.
- The curb does not match the footprint of the new unit. What are your options, and which one do you recommend? A strong answer Adapter curb, curb replacement, or field fabrication - and recommends the manufactured adapter where one exists, because a fabricated transition is a leak path and a structural question that nobody owns in two years. Raises who does the roofing work and what it does to the roof warranty.
- How do you make the duct connection at the curb so service is not chasing leaks next summer? A strong answer Proper transitions rather than forcing a mismatch, sealed with mastic rather than tape alone, gasketed at the curb, insulated, no crushed flex, and verified rather than assumed. Knows the connection is nearly impossible to inspect once the unit is sitting on it, which is exactly why it gets done badly.
- What do you do differently brazing inside an occupied building versus on new construction? A strong answer Hot work permit, fire watch, extinguisher within reach, the fire alarm notified and detectors bypassed - and restored at the end of the day, which is the part people forget. Protection for finishes, ventilation, containment, and a clean site every evening rather than at the end of the job.
- How do you rig and set a unit with a crane, and what part of the lift plan is yours? A strong answer Knows which part is theirs: unit weight and designated pick points, rigging condition and rating, tag lines, a clear landing zone, who is on the roof, and the signal arrangement. Knows the crane certification, ground bearing and the lift plan itself sit with the crane company and the general contractor, and says they would still want to see them.
- What do you check before you energise a new unit for the first time? A strong answer Voltage and phase, and specifically phase rotation on three-phase equipment. Crankcase heaters energised for the period the manufacturer asks for. Shipping brackets out, blower rotation right, filters in, panels on, disconnect and overcurrent protection correct, grounds landed. Insulation checked if the unit has been sitting outside for months.
- How do you run a line set through an occupied tenant space? A strong answer Access and hours agreed in advance and in writing rather than turning up, floor and furniture protection, dust containment, ceiling tiles handled rather than dropped, fire-stopping at every rated penetration, egress kept clear, and the space usable again at the end of each day.
- What is your leak check process, and what pressure do you test at? A strong answer Dry nitrogen to the manufacturer test pressure, never refrigerant and never oxygen, with a gauge left on it and the reading recorded against time and temperature. Bubbles or an electronic detector at every joint they made. Understands that ambient swing moves the gauge and accounts for it before calling a leak.
- How do you set hangers and supports so the piping does not transmit vibration into the building? A strong answer Isolators or spring hangers where the specification calls for them, no hard contact where a pipe passes through structure, correct spacing, and clamps that support without crushing the insulation. Thinks about the tenant below as well as the pipe.
- What documentation do you leave behind on a new install? A strong answer A startup sheet with actual readings rather than ticks, model and serial recorded, charge weighed and written down, the pressure test and evacuation records, warranty registration done, manuals handed over, and the line routing marked up as built. Treats the paperwork as the thing that makes the next technician fast.
- Describe your lockout procedure before you open a panel on a live job. A strong answer Own lock, own tag, own key, then verifying dead with a meter tested before and after. Expects more than one source of power and says so, and discharges capacitors rather than trusting the bleed resistor. On a live job, also talks to the other trades who may want that panel back on.
- What would make you stop an install and call the project manager? A strong answer A specific list: a curb or deck they are not sure will carry the unit, equipment that arrived damaged or is the wrong model, drawings that do not match the field, a missing permit or inspection, anything that voids a warranty, or scope that is not theirs. The point of the answer is that they stop rather than improvise and tell someone the same day.
The mistake this seat invites
Treating install and service as interchangeable. A strong install technician may be a slow diagnostician, and a strong service technician may be uneconomic on a production install crew.
Where the role goes next
Install technicians progress to install foreman and then superintendent, or move into service once they want the diagnostic side. Candidates ask this in the first conversation, and an employer who cannot answer it loses the people who had other options.
