Boiler Replacement in Basement

Signs It’s Time to Replace Your Boiler

Frequent Breakdowns: If you're constantly calling for repairs, it may be more affordable in the long run to install a new system.
Inconsistent Heating: Cold spots, uneven heat, or rooms that never warm up can point to a failing boiler that’s no longer keeping up.
Rising Energy Bills: Older systems often lose efficiency over time. A new boiler can help lower your monthly heating costs.
Leaking or Corrosion: Water leaks, rust, and corrosion are signs your boiler may be nearing the end of its lifespan.
Age of the System: Most boilers last 15–20 years. If yours is reaching that range, a proactive replacement can help avoid emergencies down the line.
