Can I switch from a boiler to a forced-air furnace?

Yes, but it's a substantial project — adding ductwork to a home that's never had it is the bulk of the cost. For some Tecumseh and Adrian homes with finished basements and exposed walls, the math works out. We'll give you a fully scoped quote that breaks out the duct work separately so you can see the tradeoff.

What's a high-efficiency condensing boiler?

A modern boiler that captures heat from exhaust gases that would otherwise vent up the chimney. AFUE ratings run 90-96% (vs. 70-80% for older cast iron). Vents through PVC pipe out a side wall, not a masonry chimney. Notably quieter and meaningfully cheaper to run.

When to repair vs. replace

Cast iron boilers commonly last 25-35 years with proper maintenance. If yours is over 25 and showing scale, leaks, or rising fuel bills, replacement often pencils out. A modern high-efficiency condensing boiler runs 90-96% AFUE (vs. 70-80% for older cast iron) and vents through PVC out a side wall instead of needing a chimney.

FAQ

Boilers questions, answered

Cast iron boilers commonly last 25-35 years; modern high-efficiency condensing boilers typically 15-20. If your boiler is over 25 years old and showing scale, leaks, or rising fuel bills, replacement usually makes more financial sense than another repair.
