¹Excerpts from various industry sources

This is an old AFCO (American Furnace Company) brand name originating from the 1950's. AFCO was purchased by Singer in 1968, and then spun off to become SnyderGeneral in 1982. The Comfortmaker brand name was revived at the founding of SnyderGeneral by a former Singer HVAC executive.

1950's - AFCO Introduces "Comfortmaker"  brand combination heat/air unit and firmly establishes its southern market for air conditioners.

1968 - Singer Furnace Company (subsidiary of Singer Sewing Machine Company) purchases AFCO and places it under the corporation's Climate Control Division.

Any Comfortmaker system bearing the company name "AFCO" or "American Furnace Company" will have been manufactured during the era of 1950 leading up to 1968-1970.

1970 - Became Singer American Furnace

1982 - Singer Co.'s Climate Control Division is purchased by it's then president, Richard W. Snyder, and becomes SnyderGeneral Corp. More than half the bank debt ($14 million) was paid back within 9 months, and venture capitalists who invested in Snyder were bought out by early 1984.

1984 - Snyder completes 3 major acquisitions to diversify beyond residential and into commercial and refrigeration. The first two acquisitions include Atlantic Richfield's ARCO Comfort Products Co. and the Halstead & Mitchell division of Halstead Industries. The next was a "friendly" takeover of McQuay Inc., though some sources indicate it was a hostile takeover. This third acquisition moved SnyderGeneral into the top 3 of the U.S. HVAC/R industry, just behind Trane Company and Carrier Corp. respectively, each owned by large multinational parent companies unlike SnyderGeneral.

 1984 - Singer and Singer American Furnace brand names dropped and no longer used; however, "Comfortmaker" brand was kept alive.

1991 - Economic conditions hinder financial growth of the company. With global economic recession in full swing, SnyderGeneral sets its eyes on international markets to serve as the prime area for growth. SnyderGeneral subsequently sells Comfortmaker and Arcoaire brand lines to Inter-City Products.

Any Comfortmaker product bearing the parent company name "SnyderGeneral" will have been manufactured between 1982-1991

1999 - Inter-City Products becomes wholly owned subsidiary of United Technologies Corporation. Name was changed to "International Comfort Products" at this time (abbreviated as ICP).

Any Comformaker brand bearing the parent company name "Inter-City Products" will have been manufactured between 1991-1999.

Comfortmaker brand remains owned by ICP (International Comfort Products), and is one of many heating and air conditioning brands under the ICP umbrella.

AAF International remains focused on Energy/Power and Industrial air quality applications, and similar industrial filtration applications.

2017 - AAF acquires RIS Facility Management GmbH, a leading provider of Indoor Air Quality services in Germany.

1909 - William J. Bailey began the Day & Night water heater company with Bailey's invention of a solar water heater in Monrovia, California. Bailey’s patent for his innovative system was registered in 1910 and he set to work developing and selling his product. The "Day & Night" name reflected Bailey's design that combined a solar heating element collecting heat in the daytime, and an insulated hot water storage container that would continue to provide domestic hot water during the night - providing "hot" water both day and night. Bailey's concept of a well-insulated hot water storage tank was a key feature that he later extended to a gas-fueled water heater.

1923 - Bailey sold his patent rights to Charles Ewald who founded a solar water heater company in Miami, FL. Between 1935 and 1941, more than half of Miami's population (6,000 at that time) used solar energy.

1930's - Company ventures into space heating.

1942 - World War II halted the solar industry since the government stopped the use of copper to support the war effort — one of the main components of solar. After the war, cheap electricity, higher material prices for solar systems, and older systems were replaced by newer water heaters powered by electricity and gas.

1945 - Some sources indicate Dresser Industries acquired Day & Night (not verified)

1949 - Bryant, Day & Night and Payne Furnace Co. merger to form Affiliated Gas Equipment, Inc. (AGE). All companies were then part of Dresser Industries at time of merger according to several sources.

1953 - First use of "JETGLAS" model water heaters under the Day & Night^® Water Heater brand. _{source citation} Jetglas referred to a liner coating the interior of the hot water storage tank that provided longer service life, a feature that the company promoted in advertisements which warned of leaky water heaters from its competitors.

1955 - Carrier purchases Affiliated Gas Equipment, bringing Bryant, Day & Night, and Payne brands under the Carrier umbrella.

1971 - Factory located in Collierville, TN still referred to by locals as Day & Night-Payne Company, indicating a potential yet unconfirmed company merger prior to 1949 Affiliated Gas Equipment formation. _{Source citation}

1974 - Carrier creates BDP Company comprised of Bryant - Day & Night - Payne brands.

Duo-Therm was originally part of the Motor Wheel Corporation who, prior to WWII, was the largest producer of automotive wheels in the world.

Motor Wheel Corporation diversified during the war effort to produce numerous parts for the military including wheels for a variety of vehicles (including tanks), brake drums for aircraft, and even shell casings and projectiles.

Prior to WWII, Motor Wheel Corporation had developed a furnace it marketed under the name "Duo-Therm." At some point they also developed an oil-fired water heater.

They eventually focused on mobile home and RV heating/cooling products sometime during the 1950’s. By 1961, Duo-Therm brand lines were all consolidated to the La Grange, Indiana facility, and the Lansing MI facility abandoned.

By 1975, they appear to have abandoned the heating systems to focus more on roof top a/c systems for RV’s.

In 1985, Electrolux acquired Duo-Therm from the Motor Wheel Corporation. Duo-Therm had become known for the air conditioner systems manufactured for the Recreational Vehicle industry. Electrolux leisure appliances division was renamed as "Dometic" brand in 1960's. The Duo-Therm lines were rolled into the Dometic brand name, and now only a few old dinosaurs remain with the Duo-Therm brand namesake.

1851 - I.M. Singer & Co. established by Isaac M. Singer whose patents resulted in commercially viable sewing machine

1856 - First treadle-operated machine produced.

1863 - Firm incorporated as the Singer Manufacturing Company

1867 - Builds first foreign plant in Glasgow

1902 - Builds plant in Podolsk, Russia. Singer also absorbs U.S. competitor, the Wheeler & Wilson Manufacturing Company.

1951-1957 - Domestic sewing machine market collapses due to decline in home sewing in the U.S., as well as Japanese imports taking market share. Singer begins to diversify.

1963 - Company was renamed the "Singer Company", and diversifies into electronics and aerospace.

1968 - Singer Company purchases AFCO and places it under the corporation's Climate Control Division - "Singer Furnace Company" .

1970 - Brand became Singer American Furnace

1982 - Singer Co.'s Climate Control Division is purchased by it's then president, Richard W. Snyder, and becomes SnyderGeneral Corp. More than half the bank debt ($14 million) was paid back within 9 months, and venture capitalists who invested in Snyder were bought out by early 1984.

1984 - Singer and Singer American Furnace brand names dropped by SnyderGeneral, and no longer used for HVAC systems.

1986 - Sewing machine business is spun off to a separate subsidiary as SSMC, Inc.

1987 - Singer company acquired by Paul A. Bilzerian who quickly sold off eight of the 12 remaining Singer divisions.

1990 - SSMC Inc. (remnants of original Singer Company) was sold to Semi-Tech Microelectronic's (Far East) Limited. The much-shrunken Singer Company was renamed Bicoastal Corporation.

1991 - Economic conditions hinder financial growth of the SnyderGeneral company. With global economic recession in full swing, SnyderGeneral sets its eyes on international markets to serve as the prime area for growth. SnyderGeneral subsequently sells Comfortmaker and Arcoaire brand lines to Inter-City Products.

1994 - The remainder of SnyderGeneral operations are sold to Hong Leong Group Malaysia, which is partially comprised of O.Y.L. Industries Berhad, a manufacturer of residential and light commercial HVAC equipment. SnyderGeneral is renamed "AAF-Mcquay Incorporated" and divided into two major companies: "AAF International" and "McQuay International". AAF International was based in Louisville, KY and manufactured air filtration products and systems including commercial, industrial, and residential air filters, as well as air pollution control products, machinery filtration, and acoustical systems. McQuay International was based in Minneapolis, MN where it designed, manufactured, marketed, and serviced all HVAC systems and products formerly undertaken by SnyderGeneral (with exception to the Arcoaire and Comfortmaker brands previously sold to Inter-City Products). McQuay International sold its products under various brand names, including Wesper, JennFan, Barry Blower, and AAF (commercial and institutional HVAC equipment).

2006 - McQuay International was acquired by Daikin Industries, a global manufacturer of both commercial and residential air conditioning equipment based in Osaka, Japan.

2013 - Daikin dropped the McQuay name, ending 80 years of business for the name.

Some sources indicate that the Singer brand name in HVAC systems has been recently revived by Singer-Asia with Daikin Group producing a line of mini-splits under the rebranded "Singer" name in Thailand, Bangladesh, and India (Singer-Asia). Further research indicates that Singer Bangladesh sells ductless split systems under the Singer name along with other consumer electronics and appliances also bearing the Singer name. This diversification appears to be a spinoff of the original Singer sewing machine company (separate from their climate control division), and began in Bangladesh around 1985 after SnyderGeneral dropped the Singer name from its climate control portfolio. Current Singer brand climate control systems are most assuredly rebranded products from other manufacturers such as Daikin.
