im a bit confused as to whether or not i need a contractors registration number to operate a air-conditioning business in ontario. i know that a tssa contractors number is required for any gas work, but is there any number or licence other than you c of q that you need to operate a air-conditioning repair business?

Not that I know of, but you walk a fine line when it comes to servicing the fan in a gas heating system.

Download O. Reg 75/05 - Here

Section 3(2),

(2)  A person who holds a certificate of qualification as a refrigeration and air conditioning systems mechanic, and any other person authorized under the Act to work as a refrigeration and air conditioning systems mechanic, may perform the functions described in subsection (1) with respect to any cooling system or heating-cooling combination system that is installed and used in a residential, industrial, commercial or institutional setting.  O. Reg. 75/05, s. 3 (2).

Section 3(5),

(5)  Nothing in this section authorizes a person who holds a certificate of qualification or is otherwise authorized under the Act to work in the certified trade to perform any function or carry out any activities for which a certificate is required under the Technical Standards and Safety Act, 2000.  O. Reg. 75/05, s. 3 (5).

I'm not sure if you can service a fan in a gas furnace unless you are a TSSA registered contractor, duct cleaner or the home owner. (If it's a detached dwelling).  I don't think a standard residential furnace would be considered a heating-cooling combination system.
