How AI is Transforming the HVAC Industry: An Impact study on a matured engineering domain


Centrifugal machines running on principles of Thermodynamics

I spent a part of my career in the HVAC industry many decades ago, at a time when it was firmly grounded in the disciplines of mechanical engineering and thermodynamics—both mature and deeply technical fields. Back then, optimizing system performance meant manually tweaking airflow, calculating heat loads, and understanding refrigerant behavior. I had worked with Voltas, a market leader in central HVAC systems and Fedders Lloyd, which manufactured and marketed low end Airconditioning units.

Of nuts, bolts, pipes and ducts

I find it fascinating to observe how today, the game has changed. This has been significantly due to Artificial Intelligence (AI)—a disruptive force that’s injecting intelligence, adaptability, and automation into an industry that once thrived on nuts, bolts, and thermal dynamics.

✅ Smarter Diagnostics and Predictive Maintenance

AI-powered tools now enable HVAC systems to identify faults before they cause breakdowns. Instead of relying on trial and error, it is now possible for technicians to use sensor data and predictive analytics to find the root cause quickly—whether it’s a refrigerant leak or an airflow issue.

“AI algorithms enable predictive maintenance by monitoring operational data such as temperature, pressure, and energy consumption to detect potential issues before they escalate.” — [ATA College, 2025]

These AI systems don’t just detect problems—they help prevent them, significantly reducing downtime and maintenance costs.

🌱 Energy Efficiency: Better for Business and the Planet

Energy consumption has always been one of the biggest pain points in HVAC operations. AI  can address this by learning occupancy patterns, weather forecasts, and energy pricing to optimize performance in real time.

“AI can optimize HVAC operations by responding dynamically to external conditions and human behavior, ensuring comfort without excess energy use.” — [Cooling India, 2025]

The result? Lower energy bills, improved comfort, and a smaller carbon footprint—benefiting both the bottom line and the environment.

🌡️ Personalization and Smarter Design

Modern HVAC systems don’t just heat or cool—they adapt. AI makes it possible to personalize climate control for zones or individuals based on learned preferences.

Beyond user experience, AI is improving the design phase too. Engineers can now simulate various configurations before installation, ensuring better efficiency and fewer on-site errors.

“AI is being used to create virtual simulations of HVAC systems during the planning phase, helping engineers choose the most efficient configuration.” — [Digital Defynd, 2025]

🏢 Automation and Operational Efficiency

AI doesn’t merely stop at system optimization. It can streamline administration tasks like scheduling, dispatch, and customer service through chatbots and intelligent platforms.

In smart buildings, IoT-connected HVAC systems can adjust automatically to changing conditions, cutting operational costs and improving system responsiveness.

“Intelligent building systems that include AI-driven HVAC control are emerging as a top growth area for the industry.” — [Frost & Sullivan, 2025]

⚠️ But It’s not all smooth sailing…

Ai has also brought with it certain downsides and risks.

  1. Cybersecurity is a growing concern. As HVAC systems get more connected, they become more vulnerable to attacks. To combat, companies would require to invest in data security and system integrity.
  2. Cost: AI tools, sensors, and integrations require significant upfront investment—posing a barrier for smaller firms.
  3. People factor: Many technicians will need to upskill to stay relevant. The shift is as much about mindset as it is about knowledge of the machinery.

“The technicians of tomorrow must be as comfortable with data analytics as they are with ductwork.” — [ATA College, 2025]

🌍 Looking Ahead

One needs to hold the perspective that AI is not just an upgrade—it’s a paradigm shift for HVAC. Those who embrace it will find new opportunities in efficiency, customer satisfaction, and sustainability. But success will depend on thoughtful implementation, investment in skills, and a willingness to adapt.

As someone who once worked in the traditional world of HVAC, I find it both exciting and humbling to see how far the industry has come—and how far it can still go.

Sustainability and Globalisation


Dr. Viraj P. Thacker, the best-selling author of ‘The Myth of prosperity: Globalisation and the South’, has remained passionate about continuing his Late Mother’s work of a lifetime in the areas of Women & Children, the Environment, Sustainability & Social Justice. This has also led him to set up ‘Manushi for sustainable development’ of which he is the international executive director.

I am sharing a collage of the events associated with the above initiative as well as a thought-provoking article on Globalisation that he has published recently.

Environment, sustainability and Climate Change are areas I remain passionate about. My next book might just be in this area…..

Where do we go from here?


Wonder if we look, inside our hearts, exactly what
We’d find
Or Maybe we could take a lot of pain away
Yeah
Or maybe we could heal the world today
Yeah
Or maybe, you know, something, I don’t, if you do then

Tell me    
Where do we go from here
Where do we go from here
Where do we go from here

A few weeks back I had watched the limited coverage of the national convention of the Chinese Communist Party. Rows and rows of party leaders listening and taking notes as a new leader Mr. Xi Jinping took over China’s leadership. With China’s flagging growth, Mr. Jinping is widely expected to provide his vision of the Chinese economic and living standards growth going forward.

The current UPA Government in India seems to be on its last legs and is frantically trying to reverse the ominous dip in GDP growth rates through desperate reform measures. While the jury is still out on the short-term impact of these “big ticket” reforms, it is obvious that no coalition or party can come back to power without a proven record of economic and consumption growth.

This story repeats in country after country in the developing world. Per capita growth, higher standards of living, endless availability of goods and services seems to be the universal mantra. The flickering images on the LCD panels, the endless sitcoms on myriad channels instigate us to go for that I phone 5. Or a fine dining experience. Or hanker for that newly launched car or luxury home. Our ability to consume, to pander to whims and fancies is seen as our success and growth.

But what happens when the two and a half billion folks from China and India come onto the field and want to play ball? What happens when the Chinese and Indians turn around to ask, “Hey you guys in the west, you followed your own American dream for more than a century. Now it’s our turn.”

Thomas Friedman did allude to this in his best seller ‘The World is Flat” but  said it in the context of Globalisation and a world view of a level playing field allowing everyone  an equal opportunity. Methinks however that the far more critical issue is the emerging stress on sustainability. The strain on our planet to continue to produce in pace with the exponentially rising consumption. To put it bluntly, mankind is well on course to strip this planet dry. Do see my earlier post “We need a second planet by 2030” in which consequences of mindless growth and consumption have been discussed.

So where do we go from here?

We need a shift in perspective and mindset. The twentieth century dream of conspicuous consumption cannot remain a role model any longer. This needs to be revisited, reviewed, redefined. We need to be able to answer the following.

“What really is personal prosperity, what constitutes our success?”

“Does success necessarily have to come from ownership and self-aggrandizement?”

“Could our hunger for access to better products and services be satiated, not necessarily by owning, but by sharing?”

This of course is easier said than done. We remain conditioned to acquire and own for our psychological security and comfort. This harks back to days of yore when scarcity and competing for scarce resources was the norm. This mindset continues even though access and availability is on a different plane. In our mind, Owning signifies upward mobility and prestige, of having arrived in a brave new world of capitalism. While Sharing is looked down upon as the vestige of a failed experiment called socialism.

Clearly a tectonic shift in perspective is called for. In a different context in “Age of Discontinuity and the Chinese Shi”, I had brought up the aspect of the Shi mindset which eschews the heaviness of resource ownership. Could this be a perspective that may be needed today?

I think of this and wonder who could play a catalysing role. Political leaders? Opinion makers? Media? What could be the trigger for them to buy-in and play such a role?

The good news is that technology and engineering acumen exists to achieve the above shift. Through better public transportation, better residential spaces with higher density, superior services delivery and energy efficiency, better use of public spaces, better reuse of stuff which we tend to throw away etc.The other great opportunity is of more and more “have not” folks gaining access to products and services which till now have been out of their reach.

Could this be the moment when the best tenets of Capitalism and Socialism coalesce and synergise to open up the path to sustainability?
