Brand History


Clare Furnaces, originally known as Clare Brothers, began production in 1840 in Canada.  By the early 1900s, Clare distributed a full line of heating and cooling products all across Canada.  


Clare was acquired by Toromont Group and then later was a part of Dettson Incorporated of Quebec.  Dettson was later purchased by International Comfort Products (ICP). The registered trademark for the brand known as Clare was cancelled in 2011. 




Clare manufactured gas and oil furnaces for residential customers.  ICP produces furnaces under the names of Arcoair, Comfortmaker, Heil, KeepRite and Tempstar.  ICP is the subsidiary of United Technologies Corporation. 


While Clare furnaces are no longer in production, parts can still be obtained.  Previous products by Clare are the OHB oil furnaces and the HEG, or Megasave, gas-burning furnace.  


Clare furnaces warranties are no longer available through Clare, but may be available and still in effect through ICP.
