Local notes for Greater Toronto Area

  • Gas equipment in Ontario (gas Furnaces, gas Water Heaters) must be installed by TSSA-registered contractors; someone was fined over $7,000 for unauthorized gas Furnaces installation without TSSA approval (TSSA Enforcement Notice).

Saving money & avoiding pitfalls

  • Annual maintenance plan (monthly payments) is good for those who don’t want yearly contact with technicians but compare total yearly cost.
