About

Degree Day Dollars is an independent information site about the cost of replacing home heating in Canada: air-source, cold-climate and ground-source heat pumps, gas and oil furnaces, and hydronic boilers. It explains how heating quotes are built (heat loss, capacity, equipment and installation extras), how to compare running costs with your own energy prices, and which rules matter: the 2026 status of federal and provincial programs, GST/HST and provincial sales taxes, permits, licensed gas fitters and refrigeration technicians, consumer protection rules on rentals and door-to-door sales, warranties and complaint routes.

It is written for homeowners replacing a furnace or boiler, oil-heated households considering a conversion, and anyone checking an HVAC quote or contract. The site names official sources, such as Natural Resources Canada, the Canada Revenue Agency, provincial consumer protection offices, the TSSA in Ontario, the Régie du bâtiment du Québec, Technical Safety BC and provincial program administrators, so you can confirm the current rules yourself.

The site does not sell or install equipment, rank contractors or brands, or give legal, tax or engineering advice. Prices are illustrative and are used only to show the arithmetic. Programs change often; where we could not confirm a detail as of the date shown, we say so and point to the official source.
