27 HVAC names: 8 in St. Catharines, 6 in Niagara Falls, 4 in Welland, 4 in Thorold, 3 in Hamilton, plus Port Colborne and Niagara-on-the-Lake one each. Smithville, West Lincoln, Lincoln, Fort Erie, Grimsby, Pelham, and Wainfleet have none in the file. Furnace and gas work is a TSSA fuels matter.
Names and addresses come from public sources: the 2022 Niagara Employment Inventory, City of Hamilton open data (licensed garages), and OpenStreetMap. Phones and websites appear only when those sources already had them; a listing is not a licence — check STO, ESA, or TSSA yourself when the trade requires it. Featured placements are labelled advertising ($29/mo or $249/year), not rankings. Full detail.
