Boilers FAQs
Answers to the most common questions.
How long does a boiler last?
Traditional cast iron boilers can last 25 to 30 years with good maintenance. Modern high-efficiency condensing boilers typically last 15 to 20 years. Annual servicing is essential to reach those lifespans.
Should I replace my old boiler with a high-efficiency model?
If your boiler is over 15 years old and operating below 80% efficiency, upgrading to a 95%+ AFUE condensing boiler can cut your heating bill significantly. We provide a full cost-benefit analysis during your free quote.
Can you convert a steam system to hot water?
Yes, but it is a significant project that involves replacing radiators, piping, and the boiler itself. We assess whether conversion makes sense for your property or if a modern steam boiler is a better fit.
What brands of boilers do you install?
We install and service all major boiler brands including Viessmann, Weil-McLain, Navien, IBC, Lochinvar, Buderus, and more. We recommend the right brand based on your property and budget.
Do you service commercial boilers?
Yes. We service commercial and multi-unit residential boiler systems across the GTA, including preventive maintenance contracts for property managers and facilities teams.
