Furnace tools, built on documented data
Each tool runs on this site's verified catalogue: fault codes from manufacturer manuals, model data from product sheets, permit rules from Technical Safety BC, and dates shown on every result. Tools give a starting point — a confirmed diagnosis, quote or heat-loss calculation comes from a BC Wide visit.
