A commercial HVAC technician keeps rooftop units, split systems, boilers and chillers running in offices, schools, stores and light industrial buildings. Most days mix planned maintenance with breakdown calls. The caller is usually a facility manager who needs the building comfortable before people arrive.

The diagnosis skills carry over from home service. The equipment is larger, much of it sits on roofs and in mechanical rooms, and the customer is a facility manager working from a contract.
Check the type printed on the EPA card
EPA splits Section 608 certification by kind of equipment. Type II is for high-pressure systems. Type III is for low-pressure systems, and EPA's Type III test topics cover low-pressure centrifugal chillers. A tech who holds only Type II can't legally put gauges on a low-pressure chiller, or add or remove its refrigerant. If your techs rotate through buildings with chillers, hire for Universal, which covers every type. Source: U.S. EPA: Section 608 technician certification test topics.
Skylights are holes in the roof
Office and warehouse roofs often put rooftop units a few steps from a skylight. OSHA's general industry rule treats a skylight as a hole. Workers near one need a cover, a guardrail, travel restraint or personal fall arrest gear. The same rule calls for fall protection when work is less than 6 feet from a low-slope roof edge. Look at where the unit sits before the panels come off. Source: OSHA: Fall protection in general industry (29 CFR 1910.28).
Good notes get repairs approved
On a maintenance visit the tech may work through filters, belts and coil cleaning on many units at one site. Problems found along the way go to the facility manager as a quote, and most need approval before work starts. A note with the unit number, the reading and a photo gets a quick yes. A note that says "needs repair" sits in an inbox.
Many breakdowns start in the controls
Many offices and schools run their equipment from a building automation system. A unit that won't start may be fine: the schedule is wrong, a sensor failed, or someone left it overridden. Good techs check the controls screen before condemning a part, and they release every override they set during testing. Otherwise the building runs wrong after they leave.
School work can mean a badge and a background check
Some states screen contractor workers before they work at public schools. In Florida, contract workers on school grounds while students are present need a fingerprint-based criminal history check, with some exceptions. They get a statewide ID badge from the district that must be visible at all times on campus. They must also tell their employer and the district within 48 hours if arrested for a listed offense. Check your state's rules if you service schools. Source: The 2026 Florida Statutes: Section 1012.467, background screening for school contractors.
How much commercial HVAC technicians make
The closest BLS group for commercial HVAC technicians is heating, air conditioning, and refrigeration mechanics and installers. Heating, air conditioning, and refrigeration mechanics and installers who work for plumbing, heating, and air-conditioning contractors earned a median of $28.86 an hour ($60,030 a year) in May 2025, according to the Bureau of Labor Statistics. That’s about the same as the $61,010 median for heating, air conditioning, and refrigeration mechanics and installers in all industries. About 297,290 of the 409,670 heating, air conditioning, and refrigeration mechanics and installers in that survey work for HVAC and plumbing contractors.
The template allows an hourly rate or a salary. Either way, federal overtime rules still cover a commercial tech who doesn't manage people, whatever the pay level. Some contractors pay extra for on-call weeks, or a bonus for repairs found and sold on maintenance visits.

The pay line in the template above is an example from our Role Blueprint. Set yours from these figures and what local companies pay.
Skills to hire for, and what you can teach
Hire for these
Diagnoses packaged and split systems from wiring diagrams, meters and gauges
Reads mechanical drawings, schematics and sequences of operation
Works safely on roofs, around three-phase power and under lockout
Writes unit-by-unit notes a facility manager can approve from
Runs a full day alone at one large site or several small ones
Holds the EPA 608 type your equipment calls for
Teach these on the job
The building automation systems your customers use
Boiler and chiller service, for techs who came up on rooftop units
Your maintenance checklists and service reports
Each customer's check-in, key and roof access rules
Your work order or CMMS software
Commercial techs carry a meter rated for three-phase work, refrigerant gauges or probes, a recovery machine, a vacuum pump with a micron gauge, a combustion analyzer for boilers and gas-fired units, and a laptop or tablet for controls and work orders. Tell applicants which equipment brands and controls systems they'll see most, and whether the job comes with a truck.
Commercial HVAC technician interview questions
They have their own page: 6 questions that test this job, what strong and weak answers sound like, and a work exercise to run with your finalists.
Set each target from your own service history. Compare techs on similar work, since a day of filters and belts and a chiller diagnosis aren't the same day.
First-Time Fix Rate
Repairs finished on the first trip, out of all repair calls, from your work orders. Count a return trip for a part the customer had to approve, or one that shipped from the factory, on its own line.
Customer Satisfaction Rating
Ratings from the facility manager on each account, through a short survey after repair calls and a check-in before each agreement renews.
Average Service Call Completion Time
Time on site from check-in to sign-off on repair calls, grouped by equipment type. Track maintenance visits apart, since a site with many units fills a whole day.
Callback Rate
Repeat visits for an unchanged fault on one unit within your callback window, divided by the tech's repair calls each month. Note which ones turned out to be controls problems.

Do commercial HVAC technicians need a state license?
The template asks for "relevant state licensing," and that depends on where you work. BLS notes that only some states and localities license HVAC technicians, so there's no single answer. Check with your state's licensing office and each city where you take jobs before you post, then name the exact license in the ad instead of just writing "licensed." The federal rule that applies everywhere is EPA Section 608 certification for refrigerant work.
How much does a commercial HVAC technician make?
Heating, air conditioning, and refrigeration mechanics and installers who work for plumbing, heating, and air-conditioning contractors earned a median of $28.86 an hour ($60,030 a year) in May 2025, according to the Bureau of Labor Statistics. The middle half earned between $47,790 and $75,510 a year. Pay also depends on your local market, experience and overtime.
Can a residential HVAC technician move into commercial work?
Yes, with a plan. The refrigeration cycle, electrical testing and combustion checks carry over. What's new is three-phase power, economizers, building controls, boilers and larger hydronic systems, and daily roof work. Pair a residential hire with a commercial tech on maintenance routes for the first few months. Check their EPA card too, since chiller work may need a type they don't hold.
What's the difference between a commercial HVAC technician and a building engineer?
A building engineer works for the property. They're usually on site every day and handle all of its systems: heating and cooling, plumbing, lighting and more. A commercial HVAC technician works for a contractor, visits many buildings, and goes deeper on heating and cooling equipment. Building engineers often call your techs for the repairs they can't do in-house, so good techs treat them as partners.
Do commercial HVAC technicians work nights and weekends?
Some of the time. Most service happens on weekdays, but stores, schools and offices often want equipment shut down while nobody is inside. That can mean an early start, an evening or a Saturday. Breakdowns also come in after hours when a building loses heat or cooling. Tell candidates how often they'll be on call and how after-hours work is paid.
What should a commercial HVAC technician's first week look like?
Spend it on safety and on your biggest accounts. Walk through your lockout steps, roof access rules and fall gear before the first climb. Then ride along with a senior tech on the sites they'll cover, so they learn each building's contacts, keys, equipment and quirks. Hand them solo calls once they've seen your work order and quote process from start to finish.
