Our Heritage


James A. Trane immigrates to La Crosse, Wisconsin from Norway with his parents.


James Trane opens his own plumbing business in La Crosse, Wisconsin. He quickly earns a reputation as one of the area’s best plumbers.


James, his daughter, Stella, and his son, Reuben, incorporate The Trane Company and produce a new type of low-pressure steam heating system that James engineered. In addition to this innovative system, the company manufactures valves and traps for radiators.


Reuben Trane develops a new approach to selling his company’s products and opens what is now called the Trane Graduate Engineer Training Program. This program, initially intended for Trane engineers and sales personnel, was the first of its kind and is still regarded as the industry’s finest. In the program, engineering graduates from prominent colleges and universities are recruited to receive an intensive post-graduate training regimen encompassing sales, engineering, HVAC systems design and application. After successfully completing the program, graduates advance to sales or management assignments within the company.

Reuben Trane invents a new type of heat transfer device known as the "convector radiator." This highly efficient, lightweight replacement for the bulky, slow responding cast iron radiator revolutionizes the heat exchanger industry and sets a new standard for the industry.


Trane patents the fin and tube heat transfer surface concept used within the convector radiator, and it becomes the most widely used heat exchanger in the HVAC industry.


While Trane began manufacturing with a partner in Canada in 1924, a dominion charter is granted to The Trane Company of Canada, Ltd. in 1928. This would be the first of many manufacturing sites outside the U.S.


Trane engineers, Reuben Trane and Reuben Anderegg find that the fin and tube coil works just as effectively in extracting heat from the air as it does in transferring heat to the air. The coil which made the convector and unit heater possible becomes the core of Trane air conditioners. The Trane cooling coil was first installed in an Indianapolis theater.

Shortly after the development of the cooling coil, Trane introduces the Trane Unit Cooler™. Air blows past coils, similar to those used in the convector, and circulates cool well water. The unit is designed for offices, restaurants, stores and factories.


During the Great Depression years, construction comes to a virtual standstill and the national economic paralysis makes selling heating products harder. As a result, a great deal of time is spent in a small company laboratory and the results have a far-reaching effect on the future activities of the organization. New products are developed during this period of adversity including the projection unit heater, the self-contained gas unit and the custom-air system for large buildings. These same basic designs, with modernization, are widely used today in many buildings.

Trane introduces the Oil Burning Climate Changer. This invention launches Trane into the residential cooling business and is the first time Climate Changer is associated with a Trane product.


Trane develops and later patents the Turbo-Vacuum Compressor™ (later known as the TurboVac™), a new type of water chiller with a centrifugal compressor that is the predecessor to today’s CenTraVac™ chiller. The invention provides a complete water-chilling unit that delivers cooling capacity for large air conditioning jobs by combining a centrifugal compressor, condenser and evaporator. In 2013, Trane celebrates 75 years of producing the most efficient, lowest emission, quietest centrifugal chillers.


In 1939, sales of the TurboVac™ are limited to five units. Reuben is pleased with the results, and tells shareholders that the "results were so gratifying that tooling preparations are underway for a broader program."


Trane achieves a major breakthrough during World War II by developing a new method of brazing aluminum, which ultimately enables planes to maintain high performance at higher altitudes. This process consists of alternating layers of thin aluminum and corrugated aluminum, compacting heat into one cubic foot of space. This invention introduces an entirely new design of heat exchange and paves the way for the aircraft intercooler.

Trane helps the war effort by addressing the comfort needs in wartime facilities and providing temperature-controlled solutions used in parachute drying, engine testing and shell-loading operations. In each of these instances, exact temperature and humidity are essential to keeping people and equipment safe. In addition, the Trane dry blast system assists with the production rate of blast furnace steel by quenching oil-cooling systems, which increases the production rate of shell manufacturing.


Trane expands manufacturing operations with the development of a facility in Scranton, Pennsylvania.


The post-war boom leads to rapid expansion for Trane. In 1950, the company begins manufacturing reciprocating compressors and develops the Trane CenTraVac™ as a replacement for the TurboVac™. With these additions to the product catalog, Trane has the most complete line of large central station or “applied” heating and air conditioning products for commercial, institutional and industrial applications on the market.


Trane announces its newly developed reciprocating compressor and the CenTraVac™ chiller at the American Society of Heating and Ventilating Engineers ASHVE 10th exposition in Philadelphia, Pennsylvania.


The Trane Research and Development (R & D) Laboratory opens in La Crosse, Wisconsin. The new lab, known as the Trane "House of Weather Magic," quickly becomes a symbol of the company consistently meeting the demands of the industry. Trane continues to grow its line of products and make new discoveries in the ever-changing science of heat transfer. Because of the advancements stemmed from the Trane Research and Development Laboratory, the company triples its research and testing facilities.


In September, Trane announces that the 3 millionth "convector" is sold.


With the opening of the research and development facility in 1954, a facility for engineers wasn’t far behind. In 1957, construction on a 65,000 square foot building is completed in La Crosse, Wisconsin. The L-shaped Trane Engineering Building is labeled a giant “idea factory.”


Trane expands operations and opens a plant in Clarksville, Tennessee.

Trane expands globally and acquires CEMAT, a corporation in Epinal, France. Trane renames the company to Societé Trane and establishes the company’s first European headquarters.


One of the first products to come out of the R & D facility is a completely hermetic single-shell absorption-type water chiller, the first of its kind in the industry. With the addition of the absorption chiller, Trane refrigeration products include all three basic types – reciprocating, centrifugal and absorption.

Looking to the future, Trane begins a new venture into unitary or self-contained units for commercial users such as shops. Success in this field broadens the equipment line into the residential central system air conditioning market. Furnaces and a wide variety of small commercial equipment are also added.


Trane expands operations and adds a branch plant for air handlers in Lexington, Kentucky. Manufacturing facilities begin production for Trane in Donbristle, Scotland, and Trane Western Hemisphere is formed to handle exports to Central and South American countries.


Trane builds a new plant in Epinal, France, advancing Societé Trane as a main supplier for European, Middle Eastern and African countries.


The company recognizes a new trend for the refinement of air conditioning products and builds a new acoustics facility for its laboratory activity in La Crosse, Wisconsin.


Trane acquires the Arctic Traveler Company, of Montgomery, Alabama, which manufactures a broad line of refrigeration units for trucks and trailers.


The Consumer Products Division sets out to duplicate the successful sales from engineering graduates, this time with business graduates. Trane Comfort Corps recruits salespeople at leading business schools to become company dealers and provides them training along with guaranteed loans. While the Corps’ intent is to focus on residential products, the lure of unitary, light-commercial products transitions many of the salespeople into contracting, making them some of the company’s best customers even today.

Trane opens a location in Rushville, Indiana, and hires seven employees to fabricate and assemble prototype units for a new product line – VariTrane™ is a Variable Air Volume (VAV) terminal for heating and cooling both small and large commercial buildings. VAV units are placed above the ceiling of rooms and respond to input from thermostats to control the volume of hot or cold air and ventilation to control comfort.

The first VariTrane shipment leaves the Rushville plant on December 15 and arrives at the Liberty Coach Office Building in Goshen, IN.


The Energy Crisis of the 1970’s coincides with the release of the first energy analysis software program, TRACE® (Trane Air Conditioning Economics). Trane realizes that harnessing the power of computers optimizes system selection and decreases the energy used by the entire system.

Trane expands to Latin America by acquiring COLDEX Industry and Commerce, the largest manufacturer of air conditioning and commercial refrigeration products in Brazil. This acquisition forms COLDEX Trane in São Paulo, Brazil.


Trane opens a second Societé Trane factory location in Charmes, France, expanding the company’s reach further into Europe, the Middle East and Africa.


To speed entry into the controls business, Trane acquires Sentinel Electronics Corporation in Minneapolis, Minnesota and forms Trane Sentinel. Trane continues to engineer industry-leading controls to help building owners efficiently manage and achieve the desired temperature, humidity and ventilation for their building’s purpose. In 2013, Trane celebrates 35 years of building controls excellence.

Trane acquires Service First, Inc., of Charlotte, North Carolina. This re-manufacturer of reciprocating compressors is acquired to supplement Trane’s ability to serve the air conditioning after-market.

In the transaction, Trane acquires GE’s manufacturing plants in Tyler, Texas; Trenton, New Jersey; and Fort Smith, Arkansas; its national central air conditioning distribution system; and the right to use the GE name for 3 years for products and services. The Climatuff® compressor is also included in the transaction and becomes the heart of Trane air conditioning and heat pump systems. Climatuff is well known for superior durability, low noise levels and high efficiency. This purchase substantially increases the size of Trane and is an aggressive move into the growing residential air conditioning market.

The Consumer Products Division is integrated into the former Central Air Conditioning Department of General Electric, now called Trane Dealer Products, Inc., headquartered in Tyler, Texas.

Trane ships the CVHE CenTraVac™ – its newest centrifugal chiller (direct drive, semi-hermetic, low speed). The CVHE represents a major redesign to increase energy efficiency.
