The rise of AC manufacturing in South India is changing more than where air-conditioners are assembled. It is reorganising the relationship between factories, ports, component suppliers and consumers, as manufacturers increasingly place production closer to the markets that buy cooling equipment for longer periods of the year.
Over the past five years, major manufacturers including Daikin, Blue Star, LG, Carrier and Havells Lloyd have opened factories at Sri City in Andhra Pradesh. Voltas and Mitsubishi Electric have established units in neighbouring Tamil Nadu, while Samsung India already operates a plant at Sriperumbudur. Together, these facilities are forming a manufacturing corridor running roughly 100 km from the Sriperumbudur-Chennai area to Sri City.
The shift marks a change from the geography that defined India’s AC industry for decades. Carrier’s early investment in Gurugram in the 1980s and Daikin’s plant near Neemrana in Rajasthan, established in 2008, helped create a northern manufacturing base. Until 2023, when Daikin and Blue Star began producing units at Sri City, Samsung’s Sriperumbudur facility was described as the only major southern AC manufacturing hub serving the regional market.
The scale of the southern expansion is now becoming clearer. Ravindra Sannareddy, co-founder and managing director of Sri City, told The Economic Times that the industrial city has attracted 10 AC manufacturers and 34 component suppliers in the past five years. Their combined production capacity is expected to reach eight million units next year. Sannareddy said that by 2027, about 60% of the ACs produced in India could come from Sri City alone, with the share becoming higher if plants in nearby Tamil Nadu are included.
That concentration is being encouraged by a combination of industrial policy and supply-chain economics. The report links the expansion to the Centre’s production-linked incentive scheme, which is intended to support domestic manufacturing, as well as to the strategic need to serve southern markets more efficiently. The location of Sri City, close to Chennai’s port infrastructure and to a large consumer market, gives manufacturers a reason to reassess the cost of producing in the north and shipping finished products southward.
A plant manager at one of the manufacturers in Sri City said locating production in Chennai or Sri City can save about Rs 1,200 per AC. The saving is partly linked to the region’s port access: Sri City is about 65 km north of Chennai port, while roughly 50-60% of AC components used by the industry are imported, according to the manager. A nearby port can reduce the inland movement required to bring components to factories and finished units to distribution networks.
The same geography also changes delivery time. The plant manager said the order-to-delivery cycle for customers in southern markets can fall from about 12 days to three days when production is located closer to those markets. The reported benefit is therefore not limited to transport expenditure. Shorter distances can also allow companies to replenish retailers more quickly and respond to seasonal demand with less inventory movement between regions.
This is an important distinction in understanding the industrial shift. Manufacturing location is often discussed through the lens of land, wages or incentives, but the AC industry’s decision reflects the combined value of market access, imported inputs and delivery speed. A factory situated near a port and near a large consumption region can serve two sides of the supply chain at once: it can receive components more efficiently and move finished products to customers with fewer long-distance road journeys.
Sri City’s development illustrates how private industrial cities can become specialised manufacturing clusters. The 8,500-acre industrial city in Tirupati district was established in 2008 and borders Tamil Nadu. Its attraction of AC manufacturers alongside 34 component suppliers suggests the emergence of an ecosystem rather than a series of isolated factories. Component suppliers located near assemblers can reduce coordination distances and make it easier for manufacturers to build a regional production network.
The report does not establish the precise employment generated by these factories, the value of the investments or the extent of public infrastructure spending supporting the corridor. It also does not provide a comparative breakdown of land, labour, electricity or tax costs between northern and southern locations. Those gaps matter because the long-term performance of a manufacturing belt depends on more than installed capacity. It depends on whether suppliers, workers, freight infrastructure and utilities can expand alongside factories.
What the available evidence does show is that the southern corridor is being built around an unusually strong alignment between production and demand. An engineer at another Sri City manufacturer said South India has a longer cooling season, with limited winter conditions in many cities. The engineer described the market as one where air-conditioners may be used for much of the year, rather than only during a sharply defined summer period.
That seasonal pattern changes the commercial logic of capacity. A longer cooling season can support steadier demand and reduce the extent to which factories depend on a short annual sales window. It also helps explain why manufacturers are placing production close to southern consumers even as the national AC market expands. The factory is not simply being located near a transport route; it is being located near a region where the product has a longer period of use.
The consequences extend beyond the AC industry. Manufacturing clusters tend to create demand for roads, freight services, warehousing, worker housing and civic utilities. Sri City’s expansion therefore raises questions about how industrial settlements are planned and governed as they attract more companies and workers. The supplied report does not provide evidence on housing, water, power capacity or local transport in the corridor, but the projected production scale makes those systems relevant to the next phase of the region’s growth.
The production-linked incentive scheme is another part of the institutional framework. In this case, the scheme is working alongside market and logistical factors rather than replacing them. Incentives may help make new investment viable, but the reported savings from port proximity and shorter delivery times indicate that manufacturers are also responding to the underlying geography of demand and supply. The southern shift is consequently best understood as a policy-enabled commercial realignment, not as a policy outcome in isolation.
The concentration of production also creates a structural question about industrial resilience. If Sri City alone is expected to account for around 60% of India’s AC output by 2027, the corridor could become highly important to national supply. The report does not assess the risks or benefits of such concentration, and no conclusion can be drawn here about its resilience. But the projected share shows that decisions made by a small number of manufacturers and suppliers in one industrial region may increasingly influence the availability and movement of cooling equipment across the country.
For southern cities, the story also connects rising cooling demand to the physical structure of the urban economy. Longer periods of AC use create sustained demand for appliances, installation services, electricity and maintenance. The available report focuses on manufacturing and logistics and does not quantify the resulting power demand or household affordability pressures. Those issues remain outside the evidence supplied, but they will determine how the region experiences the next phase of cooling growth.
The confirmed trend is narrower but significant: AC production is moving towards a southern manufacturing belt anchored by Sri City, Chennai and Sriperumbudur. Manufacturers are responding to imported component flows, port access, shorter delivery cycles and a longer cooling season, while the PLI scheme is supporting the broader domestic manufacturing push. The next milestones to watch are the expected eight million-unit capacity at Sri City, the continued development of component suppliers and the extent to which nearby Tamil Nadu facilities deepen the corridor’s role in India’s AC supply chain.
