The $35 Billion HVAC Software Market Proves Boring Industries Print Money

March 11, 2026

I told Derek about the HVAC software market last week and he looked at me like I had said something deeply strange. He was still upset about something involving a Star Wars film, which honestly makes every conversation with him feel slightly unmoored. But he did eventually say "who would invest in air conditioning software" and I thought: exactly. That is the whole point.

Because the answer, it turns out, is everyone. And they have been for a while.

Here is the story as I understand it, and I think it is genuinely one of the more interesting business narratives running right now. The HVAC services sector - the actual business of heating and cooling buildings, fixing units, signing maintenance contracts, dispatching technicians - is not a small, scrappy industry waiting to be discovered. The U.S. HVAC services market alone is expected to generate around $26.9 billion in revenue in 2024 and climb toward $32.9 billion by 2030. The broader global HVAC systems market - equipment, installation, everything - was estimated at over $310 billion in 2024. That is not a niche. That is a foundational industry.

And almost none of it had serious software running it until recently.

The "Boring" Premium

There is a pattern that keeps appearing in B2B software and I do not think it gets enough attention. We wrote about it a little when construction tech started attracting serious capital. The industries that look the least exciting from the outside - trades, logistics, agriculture, property management - turn out to be the stickiest software markets in existence. The reason is almost insultingly obvious once you see it: the people running these businesses do not switch tools casually. They are not playing around with a SaaS trial during a slow Tuesday. When an HVAC company adopts a dispatching and invoicing platform, that software becomes the operating nervous system of the whole business. Switching costs are enormous. Churn is almost nonexistent.

Over 75% of trades jobs are immediate or non-discretionary, which means demand stays steady even in downturns. That makes the software serving these businesses an unusually attractive model in uncertain economic times. You cannot defer getting your air conditioning fixed in July. You cannot skip the commercial HVAC maintenance contract on a hospital. The customers of HVAC contractors are themselves locked into recurring need - and that need flows straight up the stack to the software platforms managing those contractors.

The software market layered on top of this? Projected to grow at a 25.32% CAGR from 2025 to 2035, expanding from roughly $1.97 billion in 2025 to $18.85 billion by 2035. Some forecasters are more conservative - there is real variance in how analysts slice the category - but even the cautious numbers are pointing in the same direction. One estimate puts the global HVAC service software market at $1.07 billion in 2024, reaching $3.85 billion by 2032 at a CAGR of about 17.3%. Whichever number you use, you are looking at a market growing faster than most of the consumer apps that attract ten times the media coverage.

My travel agent - the one who handles Europe - once told me that the best businesses are the ones nobody thinks are glamorous. She said this while booking me into somewhere in Positano. I did not fully understand what she meant at the time, but I think about it often when I look at industries like this one.

ServiceTitan Changed the Conversation

The single clearest signal that the market had arrived was ServiceTitan going public in December 2024. ServiceTitan shares popped 42% in their Nasdaq debut after raising around $625 million in their IPO. The company, trading under TTAN, sold shares at $71 each - above the expected range - and closed on day one at exactly $101 per share, giving them a market cap of about $8.9 billion.

At that closing price, ServiceTitan was valued at 12 times trailing twelve months revenue - while the WisdomTree Cloud Computing Fund, a basket of more than 60 publicly traded cloud stocks, was trading at about 6.4 times revenue. The market was paying nearly double the going rate for cloud software to own the trades platform. That is not an accident. That is the market saying: we understand what sticky vertical SaaS in an essential industry is worth.

For the twelve months ending July 2024, ServiceTitan reported $685 million in revenue with year-over-year growth of 24%, and had grown at a CAGR of 50% from the end of 2020 to the end of 2023. That growth rate, inside an industry most people associate with white vans and manual invoices on clipboards, is the whole argument. The trades were underserved by technology for decades, and when competent software showed up, contractors adopted it aggressively. ServiceTitan describes itself as bringing an integrated SaaS platform to an industry historically underserved by technology. That framing is not modest. It is accurate.

The gross transaction volume flowing through ServiceTitan's platform reached $62 billion in the last twelve months. That represents the total invoiced by their customers to end-users, with ServiceTitan taking roughly a 0.25% cut on payment processing. That is the fintech layer sitting underneath the SaaS subscription. It is not an accident that the company built it - it is what every smart vertical SaaS platform does once it owns the workflow. You become the ledger.

And the competitors are not standing still. BuildOps announced 291 jobs in June 2025 after establishing a new operations hub in Raleigh, North Carolina - its first East Coast location - after hitting unicorn status earlier that year with a $127 million Series C. In September 2024, ServiceTitan announced a strategic partnership with Authority Brands to deploy its software platform across major franchise systems like Benjamin Franklin Plumbing, Mister Sparky Electric, and One Hour Heating and Air Conditioning. This is not a quiet little niche. This is an arms race for market position in a segment that has years of compounding revenue ahead of it.

Why the Underlying Industry Numbers Matter More Than People Realize

Software markets do not exist in a vacuum. They grow when the industries they serve grow. And the HVAC industry has structural tailwinds that are completely independent of software adoption trends.

Retrofit and replacement projects commanded 62.5% of the U.S. HVAC equipment market in 2024, and this segment is actually growing faster than new construction - at a 7.1% CAGR. This matters because replacement work is recurring, non-discretionary, and margin-rich. A homeowner with a 14-year-old unit does not shop around. They call the company that serviced it last. That relationship, and the service contract attached to it, is exactly what HVAC software is designed to capture and retain.

The average customer lifetime value for a residential HVAC client is $15,340. That is a meaningful number. It means the software tools managing those customer relationships - the CRMs, the dispatch platforms, the automated follow-up workflows - have a real return attached to them. This is not software that saves companies fifteen minutes a day. It is software that determines whether a company captures a $15,000 relationship or loses it to a competitor who sent a reminder text first.

According to ACCA survey data, 72% of HVAC firms report trouble finding skilled workers. Labor shortage forces software adoption faster than any sales pitch. When you cannot hire your way out of growth, you optimize. You automate dispatch. You implement predictive maintenance to reduce repeat visits. Workforce optimization tools enable companies to complete 18% more jobs per month without increasing staff count. In an industry where labor is the constraint, that is not a nice-to-have. That is survival.

I mentioned this to Tory when we were getting coffee and he said "that's the power of systems, Stephanie" in a way that made me think he might be thinking about something else. He has been a little distracted lately. But the point stands regardless.

The Part Everyone Is Still Sleeping On

The story is not really about HVAC. HVAC is the example. The story is about an entire class of industries - trades, field services, home services - that were functionally ignored by enterprise software for twenty years and are now being rapidly re-platformed. The software companies that got there early and achieved dominant positions are going to be extraordinarily difficult to displace.

ServiceTitan holds approximately 18% market share in HVAC field service software, with adoption among over 70% of large HVAC enterprises. That level of penetration at the top of the market means they are already the default. The question is not whether they win - it is how much of the mid-market they can capture before a well-funded competitor finds a wedge. Over 65% of HVAC contractors globally are using at least one digital scheduling or dispatch solution, which means the early adopter phase is over. The growth is now coming from consolidation and expansion within existing customers - which, for platforms like ServiceTitan, means more modules, more fintech products, more stickiness.

Industry sources suggest ServiceTitan pricing runs between $250 and $400 per managed technician per month. An HVAC company with ten technicians could be paying $3,000 to $4,000 a month for their software stack. That would have seemed absurd to this industry five years ago. Now it is considered normal because the ROI is documented and the switching cost is real. This is what healthy SaaS penetration looks like in a vertical that never had it before.

I had someone from our office configure a field service management tool for a story we were working on a few months back. She said the integration with the CRM alone took most of an afternoon. I mentioned this to Chris and he said that actually sounded pretty fast for that kind of setup, which surprised me. I did not realize there was a benchmark for these things. Apparently there is, and apparently it involves multiple days for some platforms.

Once a company has trained its technicians, migrated its customer history, and built its workflows around a single platform, the cost of leaving is measured in months of disruption. That is why the SaaSpocalypse narrative - software consolidation under pressure - plays out very differently in vertical markets. Horizontal tools get cut. Vertical operating systems do not.

This Is Not a Moment. It Is a Decade.

The $35 billion figure in the headline is not wrong, but it flattens what is actually happening. You have to look at the layers. The global HVAC systems market was estimated at $310.6 billion in 2024 and is expected to grow from $328 billion in 2025 to $545 billion by 2034. The software and services sitting on top of that equipment market are still in early innings of penetration. The integration of AI and machine learning is beginning to transform HVAC software capabilities, with predictive maintenance and operational efficiency as the primary early use cases. We are watching a full-stack digital transformation happen in real time inside an industry that most software investors would not have looked at twice in 2015.

I think the ServiceTitan IPO will look, in retrospect, like the moment the market acknowledged what had been building for years. The trades are not a sleepy backwater. They are one of the largest and most structurally durable segments of the global economy, and they are about to spend the next decade being re-platformed by software companies that understood this before the consensus did.

Derek still thinks it is boring. But Derek also thinks the prequel trilogy ruined Star Wars, which tells you something about his relationship with things that have context.

The HVAC software market is not boring. It is exactly what boring looks like from the outside when something important is happening on the inside. The air conditioning technician showing up at your door next summer is operating inside a software ecosystem that did not exist five years ago and is now worth tens of billions - and the sales infrastructure being rebuilt around these industries is part of the same story. That is not a niche. That is a platform moment.
