'''Freezer''' units are used in households and in industry and commerce.

Refrigerator freezers generally do not achieve lower than {{convert|-23|°C|°F}}, since the same coolant loop serves both compartments:  Lowering the freezer compartment temperature excessively causes difficulties in maintaining above-freezing temperature in the refrigerator compartment.  Domestic freezers can be included as a separate compartment in a refrigerator, or can be a separate appliance. Domestic freezers may be either upright, resembling a refrigerator, or '''chest freezers''', wider than tall with the lid or door on top, sacrificing convenience for efficiency and partial immunity to power outages.<ref>{{cite news |url=http://nla.gov.au/nla.news-article46453245 |title=Advertising |newspaper=[[The Australian Women's Weekly]] |location=Australia |date=19 September 1973 |access-date=13 January 2020 |page=26 |via=Trove |archive-date=25 April 2023 |archive-url=https://web.archive.org/web/20230425113411/https://trove.nla.gov.au/newspaper/article/46453245 |url-status=live }}</ref> Many modern upright freezers come with an ice dispenser built into their door. Some upscale models include thermostat displays and controls.

Home freezers as separate compartments (larger than necessary just for ice cubes), or as separate units, were introduced in the United States in 1940. Frozen foods, previously a luxury item, became commonplace.

In 1955 the domestic deep freezer, which was cold enough to allow the owners to freeze fresh food themselves rather than buying food already frozen with Clarence Birdseye's process, went on sale.<ref>{{Cite book |url=https://books.google.com/books?id=qaSDBwAAQBAJ&dq=%22Deep+freezers+go+on+sale+in+the+United+States%22&pg=PT239 |title=The Handy Nutrition Answer Book |isbn=9781578595532 |access-date=14 March 2023 |archive-date=25 April 2023 |archive-url=https://web.archive.org/web/20230425113417/https://books.google.com/books?id=qaSDBwAAQBAJ&dq=%22Deep+freezers+go+on+sale+in+the+United+States%22&pg=PT239 |url-status=live |last1=Barnes-Svarney |first1=Patricia |last2=Svarney |first2=Thomas E. |date=23 February 2015 |publisher=Visible Ink Press }}</ref><ref>{{Cite web |url=https://www.chicagotribune.com/news/ct-xpm-1990-02-25-9001170072-story.html |title=Power To The People – Chicago Tribune |website=[[Chicago Tribune]] |date=25 February 1990 |access-date=16 January 2023 |archive-date=16 January 2023 |archive-url=https://web.archive.org/web/20230116095022/https://www.chicagotribune.com/news/ct-xpm-1990-02-25-9001170072-story.html |url-status=live }}</ref>
