The $500 billion HVAC market went largely ignored for two decades, until two MIT students were stopped for a half-hour conversation by an air conditioning business owner at a Texas food service trade show.
On April 27, Avoca announced the close of its Series B round, bringing total funding to $125 million at a $1 billion valuation. Meritech and General Catalyst co-led the Series B, Kleiner Perkins led the Series A, and Y Combinator provided seed funding. The investor list is impressive, but what makes the company remarkable is that its mission diverges from every AI narrative Silicon Valley has pursued over the past decade — its customers are plumbers, roofers, and HVAC installers.
Origin story: From missed restaurant calls to a $30,000 AC job
Tyson Chen and Apurva Shrivastava met as MIT classmates during a poker night. Their first venture was not HVAC-focused; it was an AI system to capture missed calls for restaurants. The logic was simple: restaurants cannot handle all incoming calls during peak hours, losing orders.
The turning point came at a Texas food service industry conference. The founder of an air conditioning company called Rescue Air approached them: could this technology work for a business like his?
Chen and Shrivastava did the math. A missed takeout order costs a restaurant $30. A missed installation call costs an HVAC company $30,000. The same call answered by AI was worth a thousand times more.
They decided to pivot on the spot. For the next three months, they camped out in Rescue Air's office writing code, treating the AC company as their first real production environment. Rescue Air then introduced them to other companies in the industry — a sector where business owners all know each other. When one contractor had a good experience, the next would come calling within three days.
Today, Avoca serves more than 800 customers, including major service chains like Turnpoke, 1-800-GOT-JUNK?, and Goettl.
What it actually does
Many people see "AI answering calls" and assume it is just an upgraded IVR system. It is not.
Avoca's product is a complete front-office system:
- Answering calls (voice)
- Responding to emails
- Handling SMS conversations at a messaging-app level
- Dispatching and scheduling
- Following up on quotes
- Providing post-call analysis and coaching for sales staff
- Managing Google Local Services advertising accounts
This system does not replace a receptionist; it replaces an entire front-line operations team. A typical home services company employs 3-5 front-desk staff, 2 dispatchers, and 1-2 sales follow-up people. Avoca's pitch is that "the workflow of these 8-9 positions is entirely handled by an AI agent."
Shrivastava put it bluntly:
"Our AI is always-on. It can pick up a call at 3 a.m. and dispatch the job directly."
The 3 a.m. detail is not marketing fluff. In the HVAC business — when an air conditioner breaks down at midnight, a basement floods, or a roof is torn off by a storm — customers call in a state of anxiety and impulse. The company that answers the call gets the job; the one that misses it hands the customer to a competitor. That is why "a missed $30,000 call" is real money.
Numbers that make VCs sit up
Avoca's own disclosures:
- 2025 ARR exceeded 8 figures (over $10 million)
- In 2026, it expects to help customers book $1 billion in work
- Series B valuation of $1 billion
The third number is the key to the round's rationale. If Avoca takes a 1-2% cut of the $1 billion in bookings — a typical SaaS-plus-take-rate model in the industry — the company's own revenue would fall in the $10-20 million range this year. A $1 billion valuation implies a 50-100x price-to-sales multiple.
A year ago, that multiple would have seemed absurd. But in 2026, AI agent valuations are no longer anchored to SaaS logic. Cursor is valued at $50 billion; Cognition at $25 billion. When VCs frame the "AI replaces human labor" story in terms of total labor market size rather than software market size, valuations jump to another order of magnitude.
Kleiner Perkins' Leigh Marie Braswell captured the core insight:
"This is an industry that Silicon Valley has overlooked."
The fundamental reason for that neglect is not a lack of money — it is that nobody wants to deal with air conditioning repairmen personally. The typical product manager with an MBA imagines a customer profile that is "young, online, loves Slack," not Joe crawling into a basement with a toolbox at 3 a.m.
Meritech's Alex Clayton on a sentence worth highlighting
"Three years ago, AI voice for home services was not a category. Avoca created it."
The implication: Avoca is not grabbing share in an existing market; it is defining an entirely new market category.
Why does that matter? Without comparable competitors, the first mover captures category mindshare, integration channels, and the data flywheel. By the time a second or third entrant arrives, customers have already signed three-year contracts and integrated with ServiceTitan, Nexstar, and Clover. Dislodging them would cost multiples more.
ServiceTitan itself is a case in point — the HVAC SaaS pioneer is valued at $9 billion and has already gone public. Avoca did not compete head-on with it; instead, it became a ServiceTitan partner. That is a smart move: coexist with an existing player rather than try to replace it.
AI adoption in U.S. services may outpace Silicon Valley's own AI shift
Here is a counterintuitive observation.
Over the past three years, everyone has focused on AI's impact on white-collar jobs: coding, presentations, legal documents. But AI penetration in blue-collar service industries like HVAC, plumbing, and roofing may actually be moving faster by key performance indicators.
Why? Because the pain points are more concrete and the ROI is more direct:
- A single call is worth $30,000; the difference between answering it with AI versus missing it is immediately visible on the bottom line
- The decision-maker is the business owner, not a procurement committee, so contracts close quickly
- The industry is fragmented; 800 customers already make Avoca "the largest" in its space
- No existing SaaS infrastructure competes with Avoca — this market was a blank slate
Chen said something that resonates:
"The physical world still needs to be maintained. The people doing that work should have the kind of operational firepower that Fortune 500 companies have had for decades."
In plain English: Why shouldn't Joe's AC shop get a full AI-powered operations infrastructure, just like Goldman Sachs?
Avoca's answer to that question is a $1 billion valuation. The next question is: when will industries beyond plumbing — auto repair, pet grooming, housekeeping, senior care — get their turn?
