Latest / Scaling Up with Fexingo: How Small Businesses Become Mid-Market Companies / How One HVAC Company Scaled to 50 Million Without Cold Calling
Transcript
- Lucas: So there's this HVAC company in Tulsa — four trucks, one-and-a-half employees in 2020 — that just crossed fifty million in revenue. And they did it without a single cold call. Luna: No cold calling at all? In HVAC? That's almost unbelievable. How did they find customers? Lucas: Entirely through referrals. But not the passive kind — they engineered a referral system. Every job ended with a simple ask: if the customer was happy, they'd hand them three prepaid postcards addressed to neighbors. The customer filled in the neighbors' names and dropped them in the mail. The postcard offered a free diagnostic worth a hundred and fifty dollars. Luna: So the customer becomes the marketer. Did it work? Lucas: The response rate was around thirty percent. That's absurdly high for any direct mail. And because the referral came from someone the neighbor trusted, the close rate on those leads was over eighty percent. The owner told me they spent exactly zero dollars on ads or lead generation for the first three years. Luna: But referrals only scale if the service is consistently excellent. How did they guarantee that? Lucas: They built a service guarantee that was almost reckless. If the technician didn't arrive within the promised two-hour window, the diagnostic was free. If the repair didn't fix the issue on the first visit, they'd come back at no charge. And if the customer wasn't satisfied for any reason within thirty days, they'd refund the full invoice. The owner told me the guarantee cost them about three percent of revenue in lost fees. But loyalty from customers who experienced that guarantee was extremely high. Luna: Three percent is basically an investment. It probably paid for itself many times over in repeat business and referrals. Lucas: Exactly. The guarantee became a filter. Customers who cared only about the lowest price would go elsewhere. The ones who valued reliability and peace of mind were happy to pay a premium. That self-selection is critical when you're growing without a sales team — you want customers who are easy to serve, not ones who nickel and dime you. Luna: So they're not competing on price. What's the pricing model? Lucas: Flat-rate, no haggling. The company publishes all service prices on a laminated card the technician leaves behind. A standard AC tune-up is one hundred and ninety-nine dollars. A blower motor replacement is four hundred and eighty-nine. No surge pricing, no seasonal adjustments. The owner says transparency eliminates the anxiety most people feel about hiring a contractor. Luna: That's rare in trades. Most shops quote on the fly based on what they think you'll pay. Lucas: Right. And that inconsistency creates distrust. This company went the opposite direction — they made pricing boring and predictable. It worked so well that they eventually introduced a subscription service called Predictable Maintenance. For thirty-nine dollars a month, customers get two tune-ups per year, priority scheduling, and a fifteen percent discount on any repair. Today, about sixty percent of revenue comes from subscribers. Luna: That's recurring revenue in a traditionally project-based business. It must have transformed their cash flow. Lucas: Completely. Before the subscription, revenue was feast or famine — busy in summer, dead in winter. Now they have a base of regular income that covers salaries and overhead year-round. It also smooths demand, because subscribers schedule their tune-ups in spring and fall, which spreads the workload. Luna: I can see why customers subscribe. But scaling that model from zero to fifty million must have required some operational changes. Lucas: That's the part I found most interesting. The owner said the hardest shift was mental. He had to stop thinking like a technician and start thinking like a systems builder. Every process — from dispatching to invoicing to follow-up — had to be documented and repeatable. He hired his first non-technical manager when revenue hit three million, and a full-time operations director at ten million. Luna: So the growth forced a change in the kind of leader he was. Lucas: Yeah. And he admits it was uncomfortable. He used to do every installation himself. Letting go of that control was harder than any financial risk. But he says the moment he stopped being the best technician and became the best manager, the company started to scale. Luna: That's a theme we've seen in other episodes — the founder has to evolve into a different role. But I'm curious about the numbers. Fifty million in revenue — how many customers does that represent? Lucas: About twelve thousand active customers, roughly seven thousand of whom are on the subscription. They do around fifteen thousand service calls a year, plus about eight hundred installs. Average ticket is around three hundred and fifty for service, four thousand for an install. Luna: So the subscription is the engine, but the installs are where the bigger revenue comes from. Lucas: Exactly. And the subscription feeds the install business, because when a subscriber's old system finally dies, they're already a loyal customer. They call the company first. The conversion rate from subscriber to install buyer is over forty percent. Luna: That's a powerful flywheel. Referral brings in the first customer. Subscription builds loyalty. Then the big sale comes naturally. Lucas: And the whole thing runs without a salesperson. No commission, no scripts, no cold calls. The technicians are trained to diagnose and educate, not to upsell. If a customer needs a new system, the tech explains the options and the price, but there's no pressure. The company's policy is that if a customer wants to think it over, the tech leaves a written quote and follows up once by email. That's it. Luna: Honestly, if these conversations have moved your work forward in some small way, think about supporting the show. It keeps us ad-free. Lucas: Yeah, it's been a nice way to hear that the episodes actually land. If today was worth a coffee to you, that's the link — buy me a coffee dot com slash fexingo. No pressure, genuinely. Luna: And we get back to the growth story. So the technician isn't a salesperson, but they still have to convey value. How do they train for that? Lucas: Every new hire goes through a two-week boot camp that includes role-playing common scenarios. They practice explaining why a thirty-seven-dollar capacitor replacement is worth it compared to jury-rigging a fix that might fail in a month. The owner says the goal is to make the technician confident enough to answer any question without sounding like a pitch. Luna: That makes sense. The trust is built in that moment. If the technician sounds like a salesman, the trust evaporates. Lucas: Right. And the company reinforces this with a compensation model that doesn't incentivize volume. Technicians are paid a base salary plus a bonus tied to customer satisfaction scores, not to sales or number of calls completed. The bonus can be as much as twenty percent of base pay. Luna: So they reward quality, not speed. That's a smart way to prevent the temptation to rush through jobs or push unnecessary repairs. Lucas: It also reduces turnover. The owner says his average technician tenure is over four years, which is very high for HVAC. Lower turnover means more experienced techs, which means fewer mistakes and higher customer satisfaction. It's a virtuous cycle. Luna: And all of this without a sales team. I'm starting to think that for certain service businesses, the sales function is actually a symptom of weak customer experience. Lucas: I think that's right. When your service is genuinely excellent, the customers bring you more customers. But it requires a willingness to say no to the ones who aren't a good fit. The owner told me he once turned down a fifty-thousand-dollar commercial contract because the client insisted on quarterly bids and price matching. He said that client would have taken up too much management time for too little margin. Luna: That takes discipline. Most entrepreneurs would jump at a fifty-thousand-dollar contract. Lucas: He did at first. But he learned that bad-fit clients cost more than they bring in. They complain, they demand discounts, they churn quickly. His rule now is that if a prospect asks for a discount before they've even hired you, they're probably not worth serving. His company's average gross margin is forty-eight percent, which is healthy for residential HVAC. Luna: That's a great benchmark. So the entire model is built on being selective. What's next for them? Lucas: They're expanding into two adjacent markets — plumbing and electrical — using the same playbook. Same referral system, same flat-rate pricing, same subscription model. They've already launched in one city and are seeing similar early metrics. Luna: So the system itself is becoming the product. I wonder if that's replicable beyond trades. Could a lawn care company or a pest control firm copy this? Lucas: I think so, with adjustments. The key ingredients are a service that can be routinized, a pricing model that's easy to understand, and a referral mechanism that's low-friction for the customer. The owner says the single most important thing is to start with a guarantee that's actually meaningful — not just a standard 'we'll try to fix it', but something that puts real money on the line. Luna: It's a good reminder that scaling doesn't always mean spending more on sales and marketing. Sometimes it means building a system so good that your customers do the selling for you. Lucas: Exactly. And that's the kind of business that's resilient, because the growth is grounded in real value, not just ad spend.
