Why Your Techs Don’t Upsell (And How to Fix It Without Being a Jerk)

Picture This Mess

You’ve got a solid HVAC crew. Eight guys, pulling in $1.2 million a year for your shop. Then you get a call from Mrs. Johnson, who’s thrilled your tech fixed her AC—but you look at the invoice and see he didn’t even mention her 15-year-old furnace that’s one winter away from a full meltdown. That’s a $5,000 job walking out the door. And it’s not the first time. Why the hell aren’t your techs upselling?

I’ve been there. Twelve years in the field, half as a tech, half as an ops manager, and I’ve seen every excuse. Techs who think upselling is “slimy,” techs who are too shy to bring it up, techs who just want to punch the clock and go home. But here’s the thing: if they’re not upselling, you’re not growing. So let’s dig into why this happens and what you can do about it—without turning into the pushy car salesman nobody trusts.

The Real Problem: They’re Not Wired for It

Most techs are problem-solvers, not salespeople. You hired them to fix furnaces, unclog drains, or zap termites—not to pitch add-ons. When they roll up to a job, their brain is on “fix the thing, get out.” Suggesting a new water heater to a homeowner who’s already annoyed about a $300 repair bill? That feels like stepping into a bear trap.

Then there’s the trust factor. A lot of techs—especially the good ones—worry that upselling looks like they’re taking advantage. I had a guy on my crew, Dave, who’d sooner eat his toolbox than suggest a replacement unit. “I’m not here to rip people off, Mike,” he’d say. Fair enough, but when you’ve got a customer with a 20-year-old AC that’s costing them $800 a year in inefficiency, you’re not ripping them off by pointing it out—you’re helping them.

And let’s not kid ourselves: some techs just don’t care. They’re not on commission, so why bother? They’ll do the bare minimum, log the hours, and let you deal with the flat revenue.

What Most People Try (And Why It Half-Works)

So you’ve noticed the problem. Good. Most owners try one of these fixes, and I’ve seen ‘em all play out:

• The Pep Talk. You gather the crew on a Monday morning, slap some coffee on the table, and say, “Hey, guys, let’s sell more stuff. We’re leaving money on the table.” They nod, go back to their trucks, and nothing changes. Why? Because “sell more” isn’t a plan—it’s a wish. They don’t know how to bring it up without sounding like a used-car lot.

• The Incentive Plan. You dangle a $50 bonus for every upsell over $1,000. Sounds smart, right? It works for a week, maybe two. Then your top guy starts pushing unnecessary upgrades on every grandma in town, and suddenly you’ve got angry reviews on Yelp. Incentives without training are a recipe for disaster.

• The Script. You hand them a laminated card with a pitch: “Ma’am, I noticed your unit is pretty old. We’ve got a great deal on a new one.” Half the techs forget to use it, and the other half sound like robots reading it. Customers smell the script from a mile away and shut down.

These bandaids don’t stick because they don’t address the root issue: your techs aren’t comfortable or equipped to upsell in a way that feels natural. And if it’s not natural, it’s not happening.

What Actually Works: Turn Them Into Advisors, Not Salesmen

Here’s the deal—I figured this out the hard way after losing out on probably $100,000 in missed upsells one year. You don’t turn techs into salespeople. You turn them into advisors. People trust advisors. They don’t trust sales pitches. Here’s how to make that shift.

Step 1: Reframe the Mindset

Sit your crew down—individually if you’ve got the time, in a group if you don’t—and tell them this: “You’re not selling. You’re diagnosing. If a doctor sees a problem, they tell the patient. Same thing here. If you see a water heater that’s gonna blow in six months, it’s your job to warn them. Not to push, just to inform.” I used this exact line with my team, and it clicked. Dave, the guy who hated “ripping people off”? He started mentioning potential issues on every job, and his upsell rate tripled.

Step 2: Give Them a Simple Framework

No scripts. Scripts suck. Instead, give them a three-step framework they can adapt on the fly:

1. Point Out the Problem. “Hey, while I was fixing your AC, I noticed your furnace is pretty old—probably 15 years. It’s still running, but it’s not efficient.”
2. Explain the Risk. “These older units tend to break down in the middle of winter, and repairs can run $800 or more. Plus, they’re costing you extra on your energy bill.”
3. Offer the Fix (No Pressure). “We’ve got options to replace it before it becomes an emergency. I can walk you through them if you want, or we can stick with the repair for now.”

Practice this with them. Role-play it at your next meeting. Make it casual—crack a joke about the time you botched a pitch yourself. I did this with my crew, and after a month, they were bringing up add-ons without sounding like infomercials.

Step 3: Reward the Behavior, Not Just the Result

Incentives are fine, but don’t tie them directly to dollars sold. That’s how you get pushy techs and pissed-off customers. Instead, reward the effort. If a tech mentions an upsell opportunity on every job for a week—whether it closes or not—give them a $20 gift card or a shout-out at the team huddle. Track it in your field service management system if you’ve got one. I started doing this, and my team’s attempt rate went from 10% of jobs to over 50%. The revenue followed.

Practical Takeaways (Because You’re Busy)

Look, I know you’re reading this between jobs or while scarfing a sandwich in your truck. So here’s the no-BS summary:

• Stop expecting techs to be salespeople. They’re not. Train them to diagnose and advise instead. Use the “doctor” analogy if you have to.
• Ditch scripts, use frameworks. Teach them the three-step approach: problem, risk, option. Keep it natural.
• Track and reward effort, not just sales. A tech who tries to upsell on every job is worth more than one who lucks into a big win once a month.
• Be patient, but firm. This takes a few weeks to stick. Check in during your morning huddles. Ask, “Who brought up an add-on yesterday? How’d it go?” Keep it light, but keep it consistent.

I’ve seen this work with crews as small as three and as big as 25. Last year I consulted for a plumbing outfit in Ohio—six techs, doing $800K annually. After three months of this approach, they were averaging an extra $2,000 per tech per month in upsells. No angry homeowners, no shady tactics. Just honest conversations. You can do the same. Now go fix this before Mrs. Johnson’s furnace blows up on Christmas Eve—and you’re the one getting the 3 a.m. call.
