Frigidaire Appliance Company is the American consumer and commercial home appliances brand subsidiary of multinational company Electrolux, a Swedish multinational home appliance manufacturer, headquartered in Stockholm.

Frigidaire was founded as the Guardian Frigerator Company in Fort Wayne, Indiana, and developed the first self-contained refrigerator, invented by Nathaniel B. Wales and Alfred Mellowes in 1916. In 1918, William C. Durant, a founder of General Motors, personally invested in the company and in 1919, it adopted the name Frigidaire.

The brand was so well known in the refrigeration field in the early-to-mid-1900s, that many Americans called any refrigerator a Frigidaire regardless of brand. In France, Canada, and some other French-speaking countries or areas, the word Frigidaire is often in use as a synonym today, and in transcribed form in Serbo-Croatian also ("frižider", "фрижидер"). Although the alliterative names Frigidaire or its antecedent Frigerator suggest an origin of the widely used English word fridge, it is simply a contraction of refrigerator, a word in use since 1611.

From 1919 to 1979, the company was owned by General Motors. During that period, it was first a subsidiary of Delco-Light and was later an independent division based in Dayton, Ohio. The division also manufactured air conditioning compressors for GM cars. While the company was owned by General Motors, its logo featured the phrase "Product of General Motors", and later renamed to "Home Environment Division of General Motors".

Frigidaire was sold to the White Consolidated Industries in 1979, which in 1986 was purchased by Electrolux, its current parent.

The company claims firsts including:

• Electric self-contained refrigerator (September, 1918 in Detroit)
• Home food freezer
• Room air conditioner
• 30" electric range
• Coordinated colors for home appliances

In a building or a ship, a room is any enclosed space within a number of walls to which entry is possible only via a door or other dividing structure. The entrance connects it to either a passageway, another room, or the outdoors. The space is typically large enough for several people to move about. The size, fixtures, furnishings, and sometimes placement of the room within the building or ship (or sometimes a train) support the activity to be conducted in it.

A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame in the opening; the sash and frame are also referred to as a window. Many glazed windows may be opened, to allow ventilation, or closed to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.

Types include the eyebrow window, fixed windows, hexagonal windows, single-hung, and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt, and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, lancet windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, thermal, or Diocletian, windows, picture windows, rose windows, emergency exit windows, stained glass windows, French windows, panel windows, double/triple-paned windows, and witch windows.
