HVAC dispatcher job description: a free template for a small shop

An HVAC dispatcher takes the service calls, books them, assigns each job to a tech by urgency, location and skill, re-plans the day when a job runs long, and keeps customers and techs up to date. In a 1 to 10 truck shop, the same person is usually your CSR too: the voice your customers hear first.

Below is a job description you can copy and fill in, written for a small shop rather than a 40-truck operation, plus what to pay (from federal wage data), three phone tests for the interview, a first-30-days checklist, and the hours a new hire won't cover.

What does an HVAC dispatcher actually do?

The U.S. Department of Labor's O*NET database files dispatchers for service companies under “dispatchers, except police, fire, and ambulance.” Its task list, put into shop terms (O*NET 43-5032.00):

• Send techs to calls based on what the customer needs, by phone or radio, and build the day's schedule.
• Talk to customers about their questions, problems and requests for service.
• Take and write up work orders, and pass messages between the office, the techs and the customer.
• Keep the records: customer requests, work done, charges and dispatch notes.
• Re-plan the day when a repair runs long or a truck breaks down, and keep track of where techs and equipment are.
• Work out what a job needs (people, parts, equipment), and order and hand out supplies.

In a small shop, add whatever else the office needs: confirming tomorrow's appointments, chasing parts, the maintenance-agreement reminders, sometimes invoicing. Decide now which of those you're handing over, because they go in the ad.

The template: copy it and fill in the blanks

Replace everything in [brackets]. Delete any line that isn't true for your shop; an honest short ad beats a long generic one.

Three things to get right in the ad

1. Write the real hours, including on-call. If the job includes weekends on the phone, say so and say what it pays. If you're paying hourly, federal law requires at least time and a half for hours over 40 in a workweek for non-exempt employees (U.S. Department of Labor). Check your state's rules too.
2. Say the pay. It saves interviews with people you can't afford, and in some places it's the law: New York, for example, requires businesses with four or more employees to list a pay range for advertised job opportunities (New York State Department of Labor). Check your own state.
3. Describe the job, not the person. The EEOC says it's illegal to publish a job ad that shows a preference for, or discourages, applicants based on things like race, sex, religion, national origin, age (40 or older) or disability; its own example is an ad asking for “recent college graduates” (EEOC). “Calm on the phone” is a skill. “Young and energetic” is a problem.

What should you pay an HVAC dispatcher?

The Bureau of Labor Statistics doesn't count HVAC dispatchers separately. The nearest group is dispatchers working for building equipment contractors (HVAC, plumbing and electrical contractors): about 14,490 of them in May 2025, paid a mean of $24.08 an hour ($50,090 a year) and a median of $47,660 a year (BLS). Across all industries, the lowest-paid 10% of dispatchers earned under $17.32 an hour and the top 10% over $37.57, with a median of $24.20.

Pay in your town can sit well above or below that, so look at a few local job ads before you fill in the range. What a dispatcher costs you once benefits are added, and how that compares with an answering service, is in HVAC dispatcher or answering service? What a small shop really pays.

Do they need HVAC experience?

Usually not. O*NET puts the occupation in Job Zone 1–2: very little to some preparation needed, usually a high school diploma or GED, and anywhere from a few days to a year of on-the-job training (O*NET). The trade words (capacitor, condenser, heat exchanger, short cycling) can be learned in the first month. A calm voice, good notes and not losing track of five things at once are harder to teach, so hire for those.

Three phone tests for the interview

A resume won't tell you how someone sounds to a customer with no heat. Play the caller for five minutes and listen. Score each test pass or fail.

The gas answer follows the U.S. Consumer Product Safety Commission: leave immediately, contact the gas authorities from outside the home, and don't operate anything electric, like lights or phones, before leaving (CPSC). For a carbon monoxide alarm, the same CPSC page says never ignore it: get outside immediately and call 911. Nobody should be making either answer up, so both go on a card by the phone on day one. Our HVAC after-hours call guide has the full set of safety questions.

The first 30 days: a checklist

1. Week 1: sits with you or your lead tech for a day of calls; learns your service area, your techs' skills and who does what.
2. Week 1: gets your written price list (trip fee, diagnostic fee, after-hours fee) and the exact words to say them in.
3. Week 1: the safety card by the phone. Gas smell: “hang up, leave now, and call 911 or your gas utility from outside.” CO alarm: “get everyone outside now and call 911.” (CPSC says to leave and contact the gas authorities from outside for gas, and to get outside and call 911 for a CO alarm: CPSC.) Plus your own rules for smoke, fire and water that won't stop.
4. Week 2: takes calls with you listening; books into your software on their own. A word-for-word HVAC phone script gives them the questions and the fee wording to start from.
5. Week 2: knows what counts as an emergency at your shop and who to call for one.
6. Week 3: runs the board for a full day while you're in the field; you check the notes that night.
7. Week 4: confirms the next day's jobs every afternoon and handles reschedules without asking.
8. Day 30: you sit down together: what customers complain about, what calls they don't know how to handle, and what to change in the script.

The hours a new hire won't cover

A full-time dispatcher covers about 40 of the week's 168 hours. The rest is nights, weekends, lunch, sick days and vacation. Even during office hours, one person on one call means the second caller rings out. Before you post the ad, decide on paper who picks up:

• After closing: you, an on-call tech, the new hire on a paid on-call rotation, or an answering service.
• At lunch and on their days off: who the phone forwards to.
• The second call: a second line that rolls over, voicemail, or an overflow service.

If the answer is “my cell, like now,” that's fine, as long as you've chosen it. Write it down and tell the new hire, so they know what happens to calls when they go home.

Where we fit (and where we don't)

Voxlivo is the after-hours and overflow line for owner-run HVAC and plumbing shops. It doesn't replace a dispatcher or do their office work. It covers the hours they aren't there and the second call while they're on the first: it says it's a virtual assistant, takes the name, address and what's broken, books into your Google Calendar and emails you. Starter is $49 a month; Growth ($99) also rings your on-call phone for emergencies (pricing). See it for HVAC shops or read about after-hours answering.

Questions owners ask

Is a dispatcher the same as a CSR?

Not always. Some shops split the jobs: CSRs book the calls and the dispatcher runs the techs. In a small shop, one person often does both, so put both jobs in the ad and say so in the title. Running a plumbing shop? Our plumbing dispatcher and CSR job description has its own template, a booking card and plumbing phone tests.

Full-time or part-time?

Count first. Our rough rule of thumb: if scheduling, confirmations, parts and invoicing already take you 20 or more hours a week, there's a job there. If it's mostly missed calls, the two-week worksheet in our dispatcher vs answering service guide helps you decide.

Should the dispatcher take on-call calls at night?

Only if it's in the ad and you've worked out the pay. Under federal rules, someone who must stay on call at your premises is working; someone on call at home who can be reached is usually not, but the more you restrict their freedom, the more of that time may have to be paid (DOL Fact Sheet 22). Hours over 40 in a week get overtime (DOL). If it's not their job, someone else has the night phone, and the dispatcher should know who.

What should a dispatcher never say on the phone?

A repair price you haven't written down for them, an arrival time nobody can keep, and anything other than “hang up, leave and call 911 or the gas utility from outside” to a gas smell.
