Hidden Gems: Actionable, Undiscovered Opportunities in the HVAC Industry

Rising temperatures, aging building infrastructure, stricter energy efficiency standards, and the explosive growth of AI-powered data centers are all fueling demand for HVAC systems and services.

Strategic acquirers and private equity firms are increasingly looking to the sector for platform investments and add-on acquisitions. But the most attractive opportunities aren't always the most visible.

The global HVAC industry contains thousands of private companies that traditional sourcing methods and general AI tools miss. Many are founder-led companies with established customer relationships, specialized products, and decades of operating history. We call these businesses “hidden gems.” Finding them — and knowing which ones may be preparing to sell — is crucial in today’s ultra-competitive market.

We combed through our proprietary private market data to surface 79 HVAC companies in the Grata platform that are showing signs of intent to sell — and have yet to be discovered.

Methodology

What Is a ‘Hidden Gem’ Company?

We define a hidden gem as a company on the Grata platform that has not been engaged with yet. These companies are waiting to be discovered, and many have high Seller Intent scores.

What Is a Seller Intent Score?

Grata’s Seller Intent feature monitors aggregated, anonymized research at scale to flag companies that are actively in the early stages of exploring a sale.

This real-time in-market intelligence is translated into a dynamic Intent score within Grata, updated weekly, and tracked over time. This allows teams to spot accelerating sale preparation long before a banker is hired or a process launches. To summarize: these are actionable, off-market opportunities.

Key Takeaways

79 undiscovered HVAC companies show high Seller Intent scores on the Grata platform. Most of them are small: the median employs 20 people and generates about $3M in revenue.

Ownership skews founder-led and bootstrapped, meaning less competition than deals backed by institutional capital.

Opportunity in the space spans the globe, led by North America and Europe (each with 34.2%).

Seller Intent scores range widely in this cohort. About half fall between 21 and 61, while a select few top 80, marking the strongest candidates.

HVAC Hidden Gems at a Glance

Here is a snapshot of the undiscovered HVAC companies with high Seller Intent scores currently in the Grata platform:

While this cohort does contain a handful of larger manufacturers, the majority are overwhelmingly small and mid-sized businesses serving specialized segments of the HVAC value chain. The median company in the group employs just 20 people and generates around $3M in yearly revenue.

This is a compelling opportunity for private market dealmakers. Companies of this size often have established products, loyal customer bases, and significant growth potential, but they fly under the radar because traditional sourcing methods miss them.

They represent the kind of founder-led businesses that often lay the foundation of successful buy-and-build strategies.

HVAC Hidden Gems by Ownership

The ownership breakdown reflects the fragmentation in the broader HVAC industry. The overwhelming majority of undiscovered hidden gems here are bootstrapped. Founder-owned businesses are more likely to represent proprietary sourcing opportunities than companies backed by institutional capital, where competition tends to be more intense.

HVAC Hidden Gems by Segment

The current cohort of undiscovered HVAC companies showing high Seller Intent contains a mix of manufacturers and service providers. Manufacturers account for 76% of the group.

HVAC services providers have seen years of aggressive private equity roll-up activity. Contractors, installers, and repair businesses were early targets in the broader home services consolidation wave, so many attractive service providers have already been engaged, acquired, or brought into existing platforms. That shrinks the pool of undiscovered service companies.

Manufacturers followed a different path. They require more capital, more specialized product knowledge, and longer diligence cycles, which made them less attractive to the generalist roll-up strategies that swept through services. That left more manufacturers sitting untouched.

High-Intent HVAC Hidden Gems Over Time

The number of hidden gems in the HVAC industry with high Seller Intent scores fluctuates with a distinct seasonal pattern. High-intent hidden gems peak in the fall and spring months, when HVAC equipment sales and installations are highest.
