Secrets HVAC Owners Won't Tell You: Billy Gregus Shares What Actually Grows a Home Service Business

Billy Gregus started Integrity Refrigeration and AC in Winter Haven, Florida, with a contractor’s license and a side hustle. A decade later, his team runs jobs while he takes a full week off without a single call from the office. In this episode of TradeOps Radio, he breaks down the hiring philosophy that built his culture, the one decision that doubled his revenue, and why word of mouth still beats Google Ads every time.

There is a moment most HVAC owners hit, usually a year or two into running their own company, where they realize something nobody told them upfront. Being a great technician and being a great business owner are two completely different skills, and getting good at one does not automatically make you good at the other.

Billy Gregus knows that moment well. He learned HVAC through seven years of company-funded training at a flavoring corporation, earned his contractor’s license in 2015, and spent two years running service calls on nights and weekends while working his full-time job. When he went full-time in 2017, he was ready to be the best technician in the room. What he was not ready for was everything else. “A technician is not a business owner,” he said. “I had to learn that.”

Gregus is the founder of Integrity Refrigeration and AC, a commercial and residential HVAC company in Winter Haven, Florida, built on a quality-first model. Today, he runs a team of 12 field technicians and 4 office staff. His business has grown every single year. And on a recent Colorado trip, he went seven full days without receiving one call about the business.

This post covers what he shared on TradeOps Radio: the hiring system that changed everything, the marketing channels with real ROI, and the mental shift that helped him stop trading time for money.

The Gap Nobody Warns You About

Most technicians who start their own business expect the hard part to be the work. It is not. The work is the part they already know. The hard part is everything that surrounds it.

Gregus described his first few years after going full-time as still working 80 to 85 hours a week. He was answering phones mid-job, calling angry customers at 9 p.m., managing his own scheduling, and trying to build a reputation at the same time. He thought doing all of it himself was the right move. He thought he was saving money and staying in control. What he was actually doing was building a ceiling on his own growth.

The gap is structural. A business that depends on the owner to handle every role is not a business. It is a job with extra steps. Growth does not fail in these situations because the owner is not working hard enough. It fails because the systems that would allow someone else to carry the load were never built.

Reaching through that gap requires something most technicians are not taught to do: step back from execution and invest in the infrastructure around it. That shift is the whole game.

The One Decision That Doubled Revenue

Gregus spent the first year after going full-time answering the phone himself. He was in someone’s home working on a unit, and the phone would ring, and he would try to do both at once. Customers calling for the first time are often not patient. A missed call is usually a lost job.

He knew this. He still held on to the phone because he could not justify the payroll cost of someone whose only job was to answer it. That thinking kept him stuck longer than anything else.

When he finally hired a CSR, his revenue doubled the following year.

“My revenue the next year jumped 100% just off of me being able to contribute more time to working on the business,” he said. Not from a new marketing campaign. Not from a new service line. From removing one task that was consuming his attention and handing it to someone who could do it better.

This is the core principle behind Dan Martell’s WSJ bestseller Buy Back Your Time: the right hire is not the one who adds capacity to the business. It is the one who buys back the founder’s time so the founder can do higher-value work. Martell’s buyback principle states simply: do not hire to grow your business. Hire to buy back your time. Gregus arrived at the same conclusion through experience, and the results were identical.

Integrity now has four full office staff. None of them are revenue producers in the traditional sense. All of them are essential. A marketing assistant handles social content. A technician-trained office team member calls customers with open proposals and can speak the language. A recruiter keeps the pipeline moving. An office manager keeps everything accountable without Gregus having to manage each person individually.

Remove any of those roles and the quality of service degrades. That degradation costs far more than the payroll.

What Actually Works in HVAC Marketing

Gregus tracks everything. Every channel has a unique call tracking number. Every CSR call gets reviewed. Every booking rate, closing rate, and average ticket is logged and compared month over month. He knows exactly which channels are working because he has built the infrastructure to tell him.

When asked what delivers the highest ROI, his answer was immediate: word of mouth and yard signs.

Word-of-mouth drives the primary purchase decision for between 20 and 50 percent of consumers, and in a high-trust, high-ticket category like HVAC, that number is likely at the top of that range. Gregus has built specific processes to accelerate it. His techs close every call by asking if the homeowner knows anyone else who might need service. His office sends handwritten cards signed by the entire team when a referral comes in. His referral program gives customers credit toward future service when they send someone new.

Yard signs are his second highest-performing channel. They do two things simultaneously: give a homeowner with a problem a visible number to call, and build brand recognition for everyone driving past. The tracking number on each sign tells him exactly how many calls that placement generates.

Lead generation for HVAC companies that compounds over time does not always look like a media buy. It looks like systems that turn every completed job into a future referral opportunity.

Google LSA he rates as solid. Google Ads he would cut first. “If I had to choose one thing I had to drop, it probably would be Google Ads,” he said. The reason is structural. Private equity-backed platforms in his market can outspend any independent operator on bidding without blinking. The math does not work at that scale for a company that runs on quality and relationships rather than volume and velocity.

“I don’t like playing that game,” Gregus said. “I like playing the we’re local, we’re family-owned, we’re going to be there for you doing a quality job.”

SEO for HVAC companies compounds in ways that paid search does not. A website built to convert real homeowner traffic earns its cost repeatedly. Google Ads can work, but for an independent operator competing against platforms with unlimited budgets, it is the highest-risk channel in the stack.

Being Present Is a Business Decision Too

Gregus worked 60 hours a week at his full-time job and 30 more on the side for two years before going full-time in 2017. After the leap, he was still working 80 to 85 hours a week. His daughter was growing up during those years. He was at home in body but not in presence. He was thinking about the next week’s schedule while sitting across from his family.

He missed games. He missed moments. He thought that was the cost of building something.

The reframe that changed it was not financial. It was a question: if his family is the entire reason he is building the business, why is he investing less time in them than in the business? You cannot be a great dad on a part-time schedule any more than you can run a great company without putting real work into it. The same logic applies to both.

“If you’re thinking about the past, you’re not in the present. If you’re thinking about the future, you’re not in the present. You can’t change the past. You can’t really change the future. Why are you not taking full advantage of the present?”

This is not a motivational quote. It is a systems problem. An operator who cannot step away from the business has not built a business. They have built a dependency. The structure Gregus has created now lets him take a week in Colorado and come back to zero missed calls requiring his input. That result is not luck. It is the outcome of delegation, documentation, and hiring people he trusts to make decisions.

The present moment is the only place any of it actually happens. Not planning for it later. Now.

What Running the Business Looks Like Today

Gregus no longer spends his days fixing units. He spends them building the systems that make it possible for others to fix units well.

His two highest-leverage activities right now are delegation and accountability. Every team member has clearly defined responsibilities. Every day starts with a review of what was supposed to get done and whether it did. Task management runs through Trello. His calendar is blocked in advance. When he reaches 5 p.m., the work is done because the work was planned. He is not answering emails at 9 p.m. because there are people in the office who handle what those emails require.

“I am better than I am yesterday, but not as good as tomorrow,” is how he frames his standard for continuous improvement. It is not a platitude. It is a way of staying honest about how much room is always left to grow.

Integrity Refrigeration and AC passed the 10-year mark. The business grows every year. Gregus is not trying to be the biggest HVAC company in Central Florida. He is trying to be the most trusted one in his county, with a team that wakes up looking forward to the work, a culture where nobody asks if it is Friday yet on a Wednesday, and a structure that lets him be fully present when he is with his family.

That is what success looks like when you stop measuring it in hours worked.

Three Things to Take From This Conversation

Hire before you need to. The worst hire is the desperate hire. Build a continuous recruitment process now, while there is no urgency, and let it run constantly. When an A player shows up, you will be ready.

Buy back your time before you can afford to. The CSR hire feels expensive until the revenue doubles. Every role you hold onto because you think you cannot afford it is costing you more than the payroll. Find out what is keeping you in the business and hire it out.

Word of mouth is not passive. It is a system. Asking for referrals at the close of every call, sending handwritten cards, giving customers a reason to refer you immediately rather than waiting until someone asks. Build the process and it compounds.

“Read the book Buy Back Your Time,” Gregus said when asked for his single best piece of advice to an HVAC owner who is overwhelmed and stuck. That book is where to start.
