The Psychology of Service Industry Sales: How Asking Questions Transforms Customer Conversations

Introduction

The traditional approach to sales in the service industry often revolves around pushing products and talking at customers about what they "should" have. However, this approach frequently leaves money on the table while creating resistance from potential buyers. In this illuminating conversation with Gene Slade, a 30-year veteran of the HVAC industry who built and sold his own company for a seven-figure exit, we explore a transformative approach to sales that focuses on asking strategic questions rather than making statements.

Gene reveals how service technicians—from HVAC specialists to plumbers—can dramatically increase sales and company profits by mastering the psychology of customer conversations. His approach helped him build a successful company from scratch after being unexpectedly fired, using nothing but credit cards and determination, before selling it six years later for a seven-figure profit.

Whether you're a business owner looking to boost your service company's profitability, a technician hoping to increase your commission, or simply interested in the psychology of sales, this article breaks down the key principles that have helped Gene's clients double their profits without increasing their customer base. By focusing on the "massive gaps" in service businesses—the products and services that most companies miss—Gene demonstrates how the right questions can transform both your business and your customers' experience.

The Question-Based Approach to Service Sales

Bypassing the Truth/False Filter

The cornerstone of Gene's sales methodology is asking carefully crafted questions instead of making declarative statements. This seemingly simple shift creates a profound psychological impact:

"When I ask customers questions and give them information in the form of those questions, just by changing the first couple of words like 'Did you know' or 'Were you aware,' I bypass their truth-false filter," Gene explains. "They're accepting the information as an enlightenment as opposed to something that they've got to determine: is this true or is this not true?"

This approach works because whenever someone makes a direct statement to us, our internal "meter" evaluates the information. We immediately categorize it as either true or false based on our existing beliefs and biases. By framing the same information as a question, Gene creates a path around this natural defense mechanism.

Creating Self-Determined Conclusions

The goal isn't just to bypass the customer's mental filters but to lead them to reach their own conclusions about what they need:

"We control what the client is thinking and get them to come to a conclusion that something needs to be done instead of us telling them that something needs to be done," Gene says. "It always works out better if the client says it needs to be done."

To illustrate this approach in action, Gene shares his surge protection script:

"Instead of saying 'You should get surge protection,' we ask the client 'Why don't you have surge protection?' Then we say, 'Did you know that we get over 1.2 million cloud-to-ground lightning strikes a year here in this area? When we get surges and that happens, we get in-home surges. Did you know that when you get an in-home surge, your compressors can glow cherry red on the inside? Do you think that's good? What do you suppose that does to the reliability of the system? How about the lifespan? Have you ever purchased a new compressor before? So you weren't aware that a new compressor is like three grand? Can you see now why all our clients just get surge protection instead of replacing expensive compressors, motors, maybe even a whole system?'"

This sequence of questions walks the customer through a logical progression that naturally leads them to the conclusion that surge protection is essential—without the technician ever having to make that claim directly.

Focusing on Overlooked Revenue Streams in Service Businesses

Finding the "Massive Gap" in Service Companies

Gene identifies what he calls a "massive gap" in most service businesses—high-margin, high-value products and services that companies often overlook in favor of their primary services:

"80% of revenue from an HVAC company typically comes from replacing air conditioners or furnaces, but that doesn't happen but every 10 to 20 years," Gene explains. "So if we're going out to clean an air conditioner or furnace twice a year for 10 years, that's 20 appointments where we don't have an opportunity for a sale for replacing that heating and air conditioning system."

Instead of seeing these service appointments as merely maintaining the customer relationship until the next big sale, Gene focuses on all the additional products that can improve customers' lives while creating additional revenue:

"We focus on all of the other stuff that everybody else misses like filtration systems and indoor air quality systems and making sure that the air distribution system is set up right."

This approach transforms routine maintenance from a cost center to a profit center by introducing customers to valuable products they may not have known they needed.

The Plumbing Example: Root Cause Solutions

Gene applies the same principle to plumbing companies:

"For a plumbing company, the massive gap might be that the customers don't have water treatment systems and they're not selling them. As a plumbing company, every supply-side plumbing problem—meaning anything that pushes water through your house, any of the pipes, any of the valves, all that stuff—the number one root cause of all that failing is crappy water."

By focusing on the underlying cause rather than just fixing symptoms, service companies can provide more comprehensive solutions that both better serve the customer and generate additional revenue.

Building and Training Effective Sales Teams

Daily Training and Role-Playing

One of the most critical elements in building high-performing sales teams is consistent, daily training:

"In working with sales teams, one of the things I found is the most important in my opinion is daily training," Gene emphasizes. "I've studied under Grant Cardone as well, and they require 20 to 30 minutes worth of training every single day for everybody. If you missed like three in a quarter or in a year, you're fired. They say that you get rusty in as little as 12 hours. I think it's less than that."

Rather than just lecturing his team, Gene uses role-playing to ensure the messages stick:

"Every morning they would bring in their paperwork to me. We'd get around a big conference table, and I'd have two of them get up in front of the room and roleplay one of the pieces of our sales presentation. It could have been the greeting, could have been how we present the price, it could have been closing techniques, could have been objections, could have been anything."

Creating Scripts and Certification Processes

For larger teams, Gene has systematized the training process through his Lead Ninja Mastermind:

"Inside of our Lead Ninja Mastermind, which is the group that I teach twice a week, we have videos of scripts, and we've got written-out scripts. The surge protection thing we went through earlier—that's part of something they have to memorize in order to get certified through my company."

The certification process includes video recordings to ensure proper delivery:

"Once they memorize it, they take their phone, they open it up, they turn the camera on, and they say, 'Hi, this is Gene, I'm with ABC Heating and Cooling, and today I'm going to be doing the surge protection script,' and then boom, they perform it for us. One of my executive coaches will go in afterwards and see: did they nail it, did they not nail it? And we'll give them a pass or a fail."

Hiring Strategy: Choose Hunger Over Experience

When it comes to hiring, Gene takes an unconventional approach. Rather than seeking out top performers from competitors, he focuses on finding hungry, teachable people from service-oriented fields:

"I have found more success by bringing in people who have provided me or displayed good customer service, who are already in service-oriented fields, and training them on the business. I bring people from outside of the industry that don't have bad habits, that I don't have to retrain."

The results can be transformative for both the business and the employee:

"I can take a guy who's never made more than 40 grand a year, and as long as he's willing to do exactly what I tell him to do, he'll make 200 grand this year. And if I can help him do that, he'll probably do whatever I say and be loyal to me for a very, very long time."

Leveraging AI in Service Industry Sales

From Phone Calls to Sales Support

Gene is at the forefront of integrating AI into the service industry sales process:

"Not this past November but the November before that, I ended up encountering some AI software that was conversational AI that could answer telephone calls and make telephone calls and talk to you. I was like, 'Holy crap, this is scary as hell,' because I could see a world where, as the technology advances, it's AI making these sales calls."

Rather than resist this inevitable future, Gene embraced it:

"I ended up licensing the technology and immediately began to create an outbound agent that would call the existing customer bases of my clients and set them up for maintenance and service appointments. We programmed it with all of my knowledge, all of my scripting, even my radio show—everything that basically I train people in—the knowledge bank, and it does a phenomenal job."

The efficiency gains are substantial:

"It can make one phone call or 100,000 phone calls all at the same time. If I need calls on my board, if I don't have enough appointments for all my employees, with the press of a button, if I need 20 appointments in five minutes, I can have them."

The Future: AI Sales Managers and Trainers

Gene's vision for AI in service sales extends beyond scheduling to actual sales support:

"Imagine a world where you've got a guy out there that really doesn't have that much sales skills and needs help closing the deal. So he picks up the telephone and calls his AI sales manager Johnny, and Johnny ends up closing the deal for him while he's there."

The future also includes AI-driven training that happens right in the field:

"Imagine a world where in the morning they get into their trucks, these workers get into their trucks, the GPS on the truck tells their CRM they're en route, the AI goes, 'Hey, time to roleplay with Johnny,' calls Johnny up and goes, 'Hey Johnny, your price is too high, I want to think about it, I got to talk to my spouse, I need to get other quotes, how you going to handle it?' and then coaches him."

These innovations represent the cutting edge of where service industry sales is heading, with AI serving as both trainer and support system for technicians.

Conclusion: Finding Purpose Beyond the Sale

While Gene's sales techniques are undeniably effective at boosting revenue, he emphasizes that true fulfillment comes from the impact you make on others' lives:

"The first 35 years of my life, it was really just all about making the money. It wasn't that I didn't care about people, but I didn't really have a purpose. About the time I turned 35-36 years old, I was having a conversation with God, and he had revealed to me my purpose. My purpose is to help technicians, business owners, salespeople to work less, make more money, and get home for dinner on time or on the weekends."

For service industry professionals who often miss time with their families due to evening and weekend work, this mission has profound meaning:

"As a service-based business, we're always out at people's houses when they're at home, not at work. So we miss so much time, so many years, so many dinners, so many bedtime routines with our kids. If I can help somebody to triple or quadruple their income, then they've got a choice about how much they work, and they get to choose to spend more time with their family."

This purpose-driven approach ties together all of Gene's techniques—the question-based selling, the focus on overlooked revenue streams, the team building, and even the AI implementation. They're all tools that serve a greater purpose: helping service professionals achieve a better quality of life.

As Gene puts it: "If I traded the majority of my life for, let's say, $100 million, and it was sitting in the bank today, and tomorrow I die, what's the point? There's just so much more fulfillment in one of my guys, one of my students, calling me up and saying, 'Gene, I made 60 grand last year. In the last 60 days since I left your class, I've made 60 grand. My life has forever changed.'"

By focusing first on creating value for customers through thoughtful questions and comprehensive solutions, and then using that approach to transform the lives of service professionals, Gene has found a path to both business success and personal fulfillment—a model worth considering no matter what industry you serve.
