As climate change continues to drive extreme weather conditions, the heating, ventilation, and air conditioning (HVAC) industry is evolving rapidly.
HVAC companies are increasingly focusing on energy efficiency, decarbonization, and smart home tech to help commercial, industrial, and residential customers adapt.
The opportunities are massive. The global HVAC market was worth around $216B last year, and it’s projected to grow to $390B by 2033.
With over 29,000 privately-owned companies operating in the space, the HVAC industry has a wealth of opportunities for private market investors as well.
In this PE Playbook, the Grata team has put together the need-to-know trends for investors considering making moves in the HVAC market, including:
- How the industry is fragmented
- Which segments are seeing the most growth
- Notable acquisitions and roll-up activity

Industry Overview
Market Distribution
Geography

Source: Grata
In the US, HVAC companies are most densely concentrated in states that A) have large populations, and B) typically experience extreme seasonal weather (California, Texas, Florida, New York, Illinois, etc.).
However, one of the main draws of the HVAC industry is that its services are needed everywhere — even in more moderate climates. For example, North Carolina, Virginia, and Georgia are among the top 10 states with the highest number of employed HVAC workers. The South is also the fastest-growing region in the country in terms of population, which will inevitably drive demand for HVAC services. Additionally, the region has lower costs of living compared to areas like California, New York, or Massachusetts.
Ownership

The vast majority of companies in the HVAC space are independently owned. Currently, there are 29,053 private companies ripe for acquisition.
Middle-market companies comprise 25% of the industry.

Public Comparables

Because of the necessity of their services and the growing demand for energy-efficient systems, HVAC companies are strong financial performers across the board.
Commercial HVAC companies see significantly higher revenue on average due to the scale and complexity of the projects and systems they work with. These tend to yield higher-value contracts, which often include maintenance agreements that provide the companies with recurring revenue. Additionally, because commercial HVAC technicians must have advanced qualifications and specialized expertise, they can charge premium rates for their services.
However, one thing to note about the commercial sector is that it brings in the bulk of its revenue from new construction installations. As a result, it's more vulnerable to shifts in the economy.
The residential market leads in terms of EBITDA margins and revenue growth. Companies in this market generally have a more consistent customer base than the other two segments. Residential work tends to be driven by maintenance rather than new installations. Demand for these services will continue to climb as the climate changes, driving value to investors. Ongoing consolidation of mom-and-pop businesses in the space is also adding to the value of companies in the space, boosting multiples.
Meanwhile, the explosion of AI and other advanced tech solutions is driving up demand for industrial HVAC applications in industries like healthcare, semiconductors, aerospace, and data centers, according to Benchmark International. Using a considerable number of advanced electronics means these industries consume a tremendous amount of power. As a result, they need high-quality HVAC systems to maintain safe operating temperatures and help minimize carbon emissions.
Private Comparables

In the private sector, the commercial HVAC market pulls in the most average revenue by far. Because commercial systems are typically larger and more complex than residential systems, they tend to be more lucrative. The projects require commercial HVAC technicians and engineers, who have specialized training and certifications. Commercial HVAC companies also frequently lock in long-term maintenance contracts with large buildings, which yield consistent revenue streams.
Meanwhile, the industrial HVAC market is seeing the most average annual growth. This is largely tied to the industrial construction industry, which is also seeing significant growth. Dealmakers should look to areas experiencing population surges and infrastructure development, as these will drive demand for more large-scale HVAC services.

Roll-Up Activity
