Working as a field technician — no matter if you’re in septic pumping, plumbing, HVAC, or another skilled trade — means you're the face of the company. You’re not just fixing things; you're also building trust with customers, keeping projects on track with your crew and representing your employer every time you open your mouth.
And that means communication matters. A lot.
Whether you're an apprentice trying to make a name for yourself or a seasoned tech aiming to move into a leadership role, knowing what to say — and just as importantly, what not to say — on the job site can make all the difference.
Here are some practical communication tips to help you make a positive impression.
What to say
“I’m not sure, but I’ll find out for you.” No one expects you to know everything. What customers and crew leaders want is honesty and follow-through. This phrase shows humility and initiative, and it beats making something up any day.
“Can you walk me through what’s been done so far?” If you're stepping onto a job that’s already in motion, this question shows respect for your teammates' work and helps prevent costly redoes or confusion.
“Is there anything else I can help with before I wrap up?” This is a great way to go the extra mile. Whether it's helping a crew member, checking in with a customer, or ensuring the site is clean, that small gesture builds your reputation for reliability.
“Let me explain what we’re doing today.” Customers appreciate knowing what to expect. Taking 30 seconds to outline the plan — without using confusing technical or trade-oriented jargon — can calm nerves and make you look like a total pro.
“Thanks for the heads-up.” When someone points something out, even if it's a critique, this response shows you’re receptive and professional. It also avoids defensiveness, which can quickly derail teamwork.
What not to say
“That’s not my job.” Even if it technically isn’t, this phrase sends the message that you’re not a team player. A better approach is to say “Let me check in with (the supervisor) and see how they want to handle it.”
“This customer is a pain.” Keep complaints off the job site. You never know who’s listening — neighbors, cameras, even the customer through an open window. Keep it professional, always.
“We always do it this way.” This can come off as inflexible or dismissive, especially if a customer has concerns or a teammate has a suggestion. Try saying “That’s the method that’s worked well in most cases, but I’m open to adjustments if needed.”
“I already know that.” Even if you do, saying it this way can make you sound defensive or arrogant. Instead, nod and say “Got it” or “Thanks for the reminder.” It keeps things smooth and respectful.
“Whatever.” This one’s obvious. It’s vague, passive-aggressive and unhelpful. If you're frustrated or unclear, ask for clarification or take a breather if needed, but don’t check out.
Tone and body language
What you say is important, but how you say it matters just as much.
A neutral statement can come off as sarcastic if your tone or posture is off. Practice speaking clearly and confidently, making eye contact, and keeping your body language open and professional.
People notice how you communicate. Supervisors pay attention to how you handle feedback, explain things to customers and support your team. To advance in your role, begin by being mindful of your words.
Say the things that build trust. Avoid the ones that tear it down. And remember, how you talk on the job says a lot about how far you're ready to go.
Moral of the story? If you want to be a crew leader someday, start talking like one right now.
