FAQ
Common questions
How long does a boiler installation take?
Most standard residential boiler installations are completed in 1–2 days. Larger or more complex systems (including fuel conversions or zoning upgrades) may take a bit longer.
What rebates are available for boiler installation in Ontario?
We help you access Ontario energy rebates, the Canada Greener Homes Grant, and other incentives that can significantly reduce the upfront cost of your new high-efficiency boiler.
Can I switch from a furnace to a boiler?
Yes — though it's a larger project involving radiators or in-floor loops. We'll model the full cost vs. benefit before recommending the switch.
How long do modern boilers last?
Quality condensing boilers typically run 20–25 years with annual maintenance. Cast-iron boilers can last even longer.
