When Should You Schedule Boiler Maintenance?
The ideal time to schedule boiler maintenance is during the fall months, before the heating season begins. This timing will allow us to identify and address any issues before you're relying on your boiler for daily comfort. We recommend annual maintenance for optimal performance and safety.
However, you should also consider scheduling maintenance if you notice unusual noises from your boiler, inconsistent heating throughout your building, higher-than-normal energy bills, or if it's been more than a year since your last professional service. Additionally, if you're experiencing frequent cycling, unusual odors, or visible corrosion, it's time for professional attention.
