A Quick History of Home Climate Control

Last updated 5 years ago

The history of heating and cooling is full of innovations that made city life more comfortable for people all over the world. The work your air conditioning company does today is especially interesting when you consider how the systems that keep your home comfortable have evolved over time:


The Romans created under-floor systems called hypocausts, which used ducts to direct heat from basement furnaces throughout homes and larger buildings. It was a combination of convection and radiant heat that forced-air and floor systems mimic today. Though these hypocaust systems were considered 90% efficient, they took two days to preheat. European inventors developed fireplaces that inducted cold air below the fire and released it back into the room through mantle vents. In Austria, Dr. Paul Meissner developed principles that governed return-air systems, which cycle air for central heating rather than continuously introducing cold air into a furnace room or stove. This principle exists today, and all modern forced-air heating systems are based upon it.


American inventors get most of the credit when it comes to advances in cooling. As early as the mid-1700s, Benjamin Franklin discovered that the act of evaporation had a cooling effect. Willis Carrier, the founder of the eponymous cooling manufacturer, invented the first true air conditioner in 1902. The idea was to control humidity and heat by blowing air over condensing coils that drew heat from a room, cooling the air in the process. A few years later, Packard manufactured the first car with working A/C, but the controls were located under the hood. Central air conditioning became widespread in home use in the 1970s, and the main components of modern-day units have not changed much since then. However, modern air conditioners have more environmentally-friendly refrigerants, and the equipment is much more energy efficient.
