HVAC Stocks

An Irish-domiciled group listed on the NYSE with operational headquarters in North America, selling HVAC under the Trane and American Standard brands and owning Thermo King transport refrigeration. HVAC is the core, weighted toward applied commercial equipment: chillers, air handling and building controls for large buildings, with a substantial attached service business. Its heating exposure comes through heat recovery chillers and large-scale heat pumps replacing boilers in offices, hospitals and campuses.

Incorporated in Ireland and headquartered in Cork, with principal US operations in Milwaukee and roughly 87,000 employees as of 30 September 2025. On 31 July 2025 it completed the sale of its residential and light commercial HVAC business to Bosch in a transaction valued at 8.1 billion US dollars including Hitachi’s interest, covering the Coleman brand and the global residential joint venture with Hitachi. Bosch uses the York name on residential equipment under license; commercial York equipment remains with Johnson Controls. What remains is applied commercial HVAC, building controls, fire and security, and services. Its Sabroe line makes large industrial ammonia heat pumps and refrigeration equipment for the industrial and district heat market.

The largest air conditioner manufacturer in the world by volume, listed in Shenzhen with a secondary Hong Kong listing, which is the listing shown here. Air conditioning is the core but the group is broader, spanning a wide appliance range and, through the 2017 Kuka acquisition, industrial robotics. Its European heat pump business runs through Clivet in Italy and the climate businesses acquired from Arbonia. The IEA puts Chinese heat pump manufacturing capacity at roughly 35% of the global total of about 145 GW per year in 2024, and notes that Chinese makers can repurpose air conditioner lines quickly because the two products share components and production processes.

A Japanese conglomerate listed in Tokyo spanning factory automation, semiconductors, power systems, defense and building equipment. Air conditioning and home products was 31% of revenue in Q1 FY2027 (the quarter to June 2026), but that category mixes air conditioners with other appliances and does not isolate heat pumps. The Ecodan air-to-water range is one of the established hydronic heat pump lines in Europe and the UK, and Mr Slim is a widely installed light commercial range. It sells into both the air-to-water architecture common in Germany, the UK and northern Italy and the air-to-air architecture dominant in Japan and the US.

Spun out of United Technologies in April 2020 and since reshaped into a focused climate and energy business, having divested fire and security. Climate and energy solutions, including Carrier Transicold transport refrigeration, are now the whole company: FY2025 net sales were 21.75 billion US dollars across roughly 150 countries, about 47,000 employees and more than 40 brands including Carrier, Viessmann, Toshiba HVAC, Bryant, Automated Logic and Carrier Transicold. The Viessmann Climate Solutions acquisition, completed in January 2024, bought a leading European residential and light commercial position outright and added heat pumps, solar PV, batteries and hot water systems. In 2026 it sold Riello to Ariston Group (completed 1 July) and NORESCO to OPTERRA Energy Services (completed 3 August), and acquired the building-controls company 75F in July.

Distributes plumbing, HVAC, waterworks and industrial products across North America, listed on the NYSE as Ferguson Enterprises Inc., having previously traded in London as Wolseley and then Ferguson plc; the London secondary listing was cancelled in July 2026. HVAC is one customer group within a much broader building products distributor, so results follow residential and commercial construction cycles more than heating equipment demand. Air-to-water heat pumps are installed by the same trades that fit plumbing systems.

One of the world’s largest air conditioning manufacturers, listed in Tokyo, selling across residential, commercial and applied segments and owning Goodman in the United States and the Altherma air-to-water range in Europe. Air conditioning and heating is the core business, and Daikin also runs a substantial chemicals division, so it produces both its own compressors and its own refrigerants. It pioneered R32 as a lower global warming potential replacement for R-410A.

The largest dedicated air conditioner manufacturer in China, listed in Shenzhen. Unlike Midea and Haier it has stayed close to its core category, so residential and commercial air conditioning dominates revenue, supported by a substantial in-house component operation covering compressors and motors. Its sales depend on the domestic programs the IEA credits with driving adoption in China: coal-to-electricity switching in the north, the consumer trade-in scheme and stricter building energy codes. It trades only as a Shenzhen A-share, with no Hong Kong listing or depositary receipts.

A Korean group listed in Seoul spanning home appliances, media entertainment, vehicle components and business solutions. HVAC is a named group growth area alongside data center cooling. It sells the Therma V air-to-water heat pump range in Europe on top of a substantial residential and commercial air conditioning business.

A Chinese white goods group listed in Shanghai, Hong Kong and Frankfurt, with the Hong Kong listing shown here. The group sells air conditioning alongside refrigeration, laundry and kitchen appliances. It acquired GE Appliances in the United States and the Candy and Hoover brands in Europe, which gives it a distribution route into European residential heat pumps.

A Swedish engineering group listed in Stockholm built around heat transfer, separation and fluid handling, with a large installed base and attached service business. HVAC is one end market among marine, energy, food and pharmaceutical customers. Its heat exchangers go into hydronic heat pumps, industrial heat pumps and district heating loops.

A component supplier listed in Shenzhen and, since June 2025, Hong Kong, and a global leader in HVAC controls, in particular electronic expansion valves and four-way reversing valves, with a large second business in electric vehicle thermal management. It sells to the major air conditioning and heat pump manufacturers. The IEA found components and materials accounted for 60 to 85% of heat pump production cost in 2024. The four-way reversing valve lets an air conditioner run in reverse as a heat pump.

A Shanghai-listed fluorochemical producer, one of the largest in the world, spanning refrigerants, fluoropolymers and upstream fluorine chemistry, and the largest holder of Chinese hydrofluorocarbon production quota. Refrigerants are a core part of a wider fluorine business. Kigali compliance in China operates through allocated production quotas, so the phase-down leaves a controlled and shrinking supply in the hands of a small number of licensed producers. It trades only as a Shanghai A-share.

Makes residential and light commercial heating and cooling equipment under the Lennox, Armstrong Air, Ducane and Allied brands, operating almost entirely in North America and running its own distribution network alongside independent dealers. HVAC is the whole company, and its sales follow the US air conditioner replacement cycle, which the IEA identifies as the main route to American heat pump adoption because a reversible unit costs only 200 to 500 US dollars more than a cooling-only one at purchase. It owns 49.9% of a water-heating joint venture with Ariston Group established in May 2025, and completed the acquisition of Heat Controller in July 2026.

A German process engineering company listed in Frankfurt, supplying equipment and plant to food, beverage, dairy and pharmaceutical producers. Heat pumps, built on ammonia technology, sit inside the heating and cooling activities of its Pure Flow Processing and Nutrition Plant Engineering divisions, two of the four divisions in the structure adopted on 1 January 2026, and do not form a standalone unit. Its food, beverage and dairy customers are the light industry the IEA identifies as having the highest deployment potential for industrial heat pumps, because drying, pasteurization and low-pressure steam generation need heat at temperatures that heat pumps can supply.

The largest distributor of heating, ventilation, air conditioning and refrigeration equipment in North America, listed on the NYSE, operating several hundred locations and a set of joint ventures including a long-standing one with Carrier. It sells to contractors and does not manufacture equipment. Distributors carry both the inventory risk and the pricing benefit of each refrigerant changeover.

Completed its spin-off from Honeywell on 30 October 2025 and trades on Nasdaq, making refrigerants, building materials and specialty chemicals. Refrigerants are the center of the company: in FY2024, its final full year inside Honeywell, refrigerants and applied solutions accounted for 72% of net sales, with refrigerants alone contributing about 1.3 billion US dollars. It owns the Solstice range of hydrofluoroolefin low global warming potential refrigerants. Demand for them is driven by the Kigali Amendment, which had 174 parties as of August 2026 and cuts hydrofluorocarbon use by more than 80% globally by 2050. A proposed merger with Element Solutions was mutually terminated on 27 August 2026 without termination fees.

A Swedish group listed in Stockholm, built around three business areas of which Climate Solutions is much the largest. Heat pumps are the core product: air-to-water, ground-source and exhaust-air units sold under the NIBE name and a portfolio of national heating brands acquired across the Nordics, Germany, the Netherlands, the UK and North America. The other two business areas are Element and Stoves.

Makes residential and commercial water heaters, boilers and water treatment products, listed on the NYSE, with its principal markets in North America and China and a long-established position in Chinese premium water heating. That China business was under a strategic assessment as at the company’s Q2 2026 results, with management describing all outcomes, including a sale or a partnership, as still on the table. Water heating is the core business.

A Swedish distributor of heating, ventilation, air conditioning and refrigeration equipment listed in Stockholm, operating across Europe, Asia Pacific, Africa and North America, having grown by acquiring regional wholesalers. Distribution is the core, with some own manufacture of refrigeration equipment attached. It is the European and Asia Pacific counterpart to Watsco, selling to the installers who fit the equipment.

Makes semi-custom rooftop units, air handlers and condensing units for commercial and industrial buildings from plants in Oklahoma, Texas and Missouri, and has expanded into data center cooling. HVAC equipment is the whole company, built on a configured-to-order model that sits between the standardized volume manufacturers and the fully engineered applied vendors. Much commercial rooftop demand can be met by reversible units, which displace gas heating in low-rise commercial property, but heat pumps are secondary to its data center cooling business.

Makes air conditioning, refrigeration and other white goods, plus automotive thermal management through Sanden, listed in both Shenzhen and Hong Kong, with the Hong Kong listing shown here. HVAC was 48.9% of H1 2026 revenue. The company is smaller than Midea and Gree in the Chinese market and has a smaller international presence. Its commercial air conditioning business runs partly through the Hisense Bosch joint venture, formerly Hisense Hitachi, built on Japanese variable refrigerant flow technology.

A Taiwanese manufacturer of brazed plate heat exchangers listed on the Taiwan Stock Exchange, supplying European heat pump manufacturers directly, with data center liquid cooling, industrial, hydrogen and semiconductor equipment businesses alongside. The plate heat exchanger business ties it to European heat pump order patterns: it carried the European downturn that followed the 2021 and 2022 boom, and those orders turn on European subsidy schedules. It has expanded into liquid cooling for data centers, so results no longer track heat pump demand alone.

A Tokyo-listed Japanese manufacturer of gas water heaters, tankless hot water systems, kitchen appliances and heating equipment, with a substantial export business in North America and Australia. Gas-fired water heating is the core business. The IEA notes gas units remain dominant in Japanese water heating, where subsidies cover hybrid water heaters, fuel cells and high-efficiency gas systems.

A Chinese fluorochemicals and silicones producer listed in Hong Kong, making refrigerants, polytetrafluoroethylene, fluoroelastomers and organosilicon products, alongside membrane materials used in chlor-alkali and hydrogen electrolysis. The Hong Kong listing is open to overseas investors without the access programs the Shanghai and Shenzhen A-shares on this list require. The membrane business is unconnected to HVAC.

A Mexican group listed in Mexico City operating across polymer solutions, building and infrastructure, precision agriculture, connectivity and fluorinated solutions. HVAC exposure is small within the group and runs through Fluor & Energy Materials, formerly Koura, which mines fluorspar at Las Cuevas in San Luis Potosí, described by Orbia as the world’s largest fluorspar mine, and also produces refrigerants and other fluorine products. Fluorspar is the upstream feedstock from which refrigerants are made.

Spun out of DuPont in 2015 and listed on the NYSE, operating across Thermal and Specialized Solutions, Titanium Technologies and Advanced Performance Materials. Refrigerants sit in the first of those three. The Opteon low global warming potential range competes directly with Solstice, so the two together represent most Western low-GWP refrigerant supply. Titanium dioxide is a cyclical commodity, and the group carries ongoing litigation and remediation exposure relating to per- and polyfluoroalkyl substances.

A Shanghai-listed component manufacturer making rotary compressors for air conditioners and heat pumps, alongside automotive air conditioning compressors. Compressors are the core, alongside motors and castings; it is not a branded equipment maker. The IEA identifies rotary compressor manufacturing as roughly 90% concentrated in China in 2024 and calls it an acute vulnerability in the heat pump supply chain, in contrast to scroll compressors and fluorspar feedstock, which are more geographically diversified.

A Shenzhen-listed maker of HVAC valves, heat exchangers and refrigeration components, and Sanhua’s principal domestic competitor across several product lines. Components are the core business, with a more recent move into liquid cooling equipment for data centers. It has a smaller international customer base than Sanhua and a shorter record outside China.

An Italian-founded, family-controlled group listed in Milan as Ariston Holding N.V., making water heating and space heating equipment under the Ariston, Chaffoteaux, Elco, Racold and Wolf brands across more than 40 countries. It completed the acquisition of Riello from Carrier on 1 July 2026. Thermal comfort is the entire company. It sells a large gas boiler range alongside a growing heat pump range. Net revenue was EUR 2.7 billion in FY2025, up 3.0% organically, with management attributing that growth to heating heat pumps and naming Germany as the standout market.

A Milan-listed manufacturer of heat exchangers and finned coils for heating, ventilation, air conditioning and refrigeration, with plants across Europe, Asia and North America. Components for HVACR original equipment manufacturers and refrigeration system builders are the whole company, so its results track European OEM production volumes closely. On 2024 figures the IEA reports air-to-water heat pumps cost around 60% more to produce in Europe than in China, and identifies deeper European component manufacturing as one way to narrow that gap.

A Swiss company listed in Zurich making mechanical ventilation with heat recovery and decorative and low-temperature radiators, sold mainly into European residential and commercial buildings; it sold its climate-ceilings business in 2025. Ventilation was 66% of 2025 sales and radiators 34%. It does not make heat pumps. A heat pump reaches its highest coefficient of performance at low flow temperatures, which in a retrofitted building means larger emitters, underfloor systems or a ventilation strategy that cuts the heat load. Indoor climate is the whole company, and demand follows European building retrofit activity.

A Taiwanese compressor manufacturer listed in Taipei, producing rotary compressors and brushless DC motors for air conditioning and refrigeration with most of its capacity in mainland China. Compressors are the core, sold to equipment makers.
