ServiceTitan costs a 12-person HVAC company more per month than some of those techs earn in a day. My friend Danny runs a shop like that in Phoenix, and when I first suggested he look into field tracking software, he pulled up a quote from one of the big platforms and turned his laptop so I could see the number. I stopped talking for a second.
He had been using a whiteboard with magnets for each technician, sliding them between columns labeled “available” and “on site.” For a while it worked fine. Danny’s office manager would glance at the board, see who was free, and assign the next call. Simple enough when you only have a handful of techs and they mostly stay honest about their status.
The whiteboard stopped working on a Tuesday in August. A tech named Carlos was listed as “on site” at a customer’s house on the east side of town. A warranty callback came in from a neighborhood ten minutes from Carlos, and the dispatcher left it unassigned because Carlos was supposedly wrapping up.
Three hours later, the customer called back angry. Carlos had actually been at a parts supplier 20 minutes in the opposite direction the entire time. Nobody knew because the magnet said otherwise. The callback sat there, unassigned, while the customer’s frustration compounded into the kind of phone call that makes an office manager’s stomach drop.
That was the day Danny called me.
The First Suggestion Was Wrong
I told Danny to look at fleet management platforms with vehicle-mounted GPS. That was my instinct, the same instinct most people have when they hear “tracking.” Bolt a device to the van, get a dot on a map, done.
I even sent him links to OBD tracker companies and a hardwired unit that had good reviews. I had this whole pitch ready about geofencing and route history and all the bells that come with traditional fleet management. I was ready to be the helpful friend who solves the problem with the right piece of technology.
He called me back the next day and said two things that changed my mind. First, the cheapest option was going to run roughly $25 per vehicle per month on top of hardware costs per van. For a dozen vans, that math gets uncomfortable fast.
Second, and this was the part that stuck: “My guys don’t always take the same van. Sometimes they swap. Sometimes a van is in the shop and they take their personal truck.” I sat with that for a minute because it’s such an obvious problem that I’d completely overlooked. You track the vehicle, but the person you care about might not be in it.
In HVAC, the tech is what matters. The van is a toolbox on wheels.
Danny also pointed out that half his fleet was old enough that the OBD ports were unreliable. One van had a port that was physically damaged from a previous owner’s aftermarket stereo installation. Another had an intermittent electrical issue that would probably cause a tracker to reset every few days. The hardware path was looking worse the more we talked about it.
Phones Were the Backup Plan
I suggested phone-based tracking almost as an afterthought. Not my proudest consulting moment. It felt like a lesser option at the time, like suggesting a bicycle when someone asks about cars.
But Danny was already frustrated with the pricing conversation, so he was willing to try anything that didn’t involve hardware installation or per-vehicle contracts. His exact words were something like “if it doesn’t cost me a thousand dollars to set up, I’ll try it for a week.” That was the bar. A week.
The setup took less than a morning. Each tech downloaded an app on their phone, signed in, and showed up as a dot on a map. No appointments with an installer. No vans sitting idle in a parking lot while someone ran wires.
No diagnostic port blocked by a dongle that the techs would unplug anyway because the check engine light annoyed them. No waiting for a technician to show up and spend an afternoon wiring things under the dash. The whole thing was done before lunch, and Danny spent exactly zero dollars on hardware.
Within the first week, Danny could see every tech’s location updating continuously. If a customer called asking when their tech would arrive, the front desk could give an actual answer based on where the tech was right then. Not where a magnet on a whiteboard claimed they were. Not where the tech said they were the last time they picked up the phone.
The phones they already carried turned out to be better tracking devices than anything bolted to a dashboard. The update frequency alone was a difference Danny noticed immediately. His techs’ phones were sending location data every few seconds, while the OBD trackers he’d been quoted on updated roughly once a minute at best.
Danny told me later, and I’m paraphrasing only slightly: “I can see where everyone is without calling them, and they stop lying about their ETAs.”
What Changed in the Day-to-Day
The dispatching shift was the biggest one. Before, Danny’s office manager would call or text techs to ask where they were before assigning the next job. That ate up time on both ends and depended entirely on the tech answering honestly.
Now she opens a map, sees who is closest to the incoming call, and dispatches accordingly. No phone tag. No guessing. The tech finishing up a job two streets from the next customer gets assigned, not the tech who happened to answer his phone first.
That change alone saved Danny’s team a noticeable amount of drive time per week. Techs spend less time in traffic and more time at job sites. Customers get shorter wait windows, and the crew gets through more calls per day without working longer hours.
Danny’s office manager told me she used to spend the first hour of every morning calling techs to confirm they were actually heading to their first appointment. Some would answer. Some wouldn’t. She’d leave voicemails, send texts, and occasionally just sit there staring at the phone hoping someone would call back before the customer did.
With live tracking, she opens the map each morning and can see every tech moving toward their first stop. If someone isn’t heading out yet, she knows before the customer notices. That visibility alone changed how her mornings felt.
Proof of arrival was the other piece Danny didn’t expect to care about. Warranty work and insurance jobs sometimes require documentation showing when a tech arrived and departed. With phone-based tracking, that timestamp exists automatically.
The tech doesn’t have to remember to log it. The customer doesn’t have to sign a form confirming the time. It just happens in the background, and when someone disputes a service window, the data is already there.
Danny had a situation a few weeks in where a customer claimed a tech spent only ten minutes on a repair that should have taken an hour. The tracking data showed the tech was on site for 55 minutes. Without that data, it would have been the tech’s word against the customer’s, and those conversations never end well for the service company.
One thing I noticed when I visited Danny’s office a few months in: the whiteboard was still on the wall. The magnets were still on it. But nobody had moved them in weeks.
Decoration. A relic of a system that felt adequate until it wasn’t.
The ROI conversation is almost embarrassingly simple. Danny pays nothing for hardware. His techs’ phones are already on their person every minute of the day. Compare that to a per-vehicle monthly fee plus hardware costs for a traditional tracker across a dozen vans, and the savings add up before you factor in the efficiency gains from smarter dispatching.
A phone-based field tracking tool costs a fraction of what hardware solutions charge, and it tracks the person instead of the vehicle. That distinction matters when your techs swap vans or take personal trucks to overflow job sites on busy days.
Danny ran the numbers after his first full quarter with phone tracking. He compared what the OBD fleet solution would have cost him over those months against what he actually spent. The gap was wide enough that he used the savings to buy a new set of gauges for one of his techs.
He said that felt more productive than paying a subscription fee to watch a dot move on a screen attached to a van that might not even have the right person in it. I couldn’t argue with that logic. The whole point of tracking is knowing where your people are, and if the system you’re paying for can’t reliably tell you that because people and vehicles don’t always travel together, then you’re paying for a partial answer.
There’s also the customer-facing side that Danny didn’t anticipate. When a homeowner calls to ask where their tech is, the person answering the phone can give a real answer. Not “he should be there soon” but “he’s about ten minutes out, finishing up a job on the next block.” That kind of precision changes the tone of the conversation entirely. The customer feels informed instead of ignored.
What Nobody Tells You About the Transition
The techs pushed back. Of course they did.
Carlos, the same tech who had been at the parts supplier while his magnet said “on site,” was the most vocal. He didn’t want his boss watching his phone all day. That’s a fair concern, and Danny handled it by being blunt: “I could already see you weren’t where you said you were. This just makes it official.”
The discomfort faded within a couple of weeks once the techs realized the tracking worked in their favor too. When a customer complained that a tech “showed up late,” Danny pulled the data and showed the tech arrived on time. The accountability cut both directions, and the crew came around once they saw that.
One tech told Danny that the tracking actually made his life easier because dispatch stopped calling him to ask where he was. He could just do his work without interruptions. That was an angle neither Danny nor I had predicted, and it turned out to be the thing that won over the skeptics faster than any privacy conversation could have.
Battery drain was the other complaint. Early on, a couple of techs said their phones were dying by mid-afternoon. Danny bought a pack of car chargers in bulk. Problem gone.
There’s also the question of what happens when a tech leaves their phone in the van while they’re inside a customer’s house. In practice, this matters less than you’d think. The phone updates frequently enough that a stationary dot at a customer’s address tells you what you need to know: the tech is there, doing the job.
You don’t need precision to within three feet. You need to know which house they’re at, and a phone in a van in the driveway handles that just fine. Danny stopped worrying about that scenario after the first month because it never once caused an actual problem.
I asked Danny recently if he’d go back to the whiteboard. He laughed. Not a polite laugh either.
The magnets are still on the wall though. He says they’re a good reminder of how long he ran a business blind.
