How Often Does a Commercial Boiler Need Service in New York?

March 10, 2022


It’s important to maintain your commercial boiler regularly throughout the year.

If you own or manage a building with a commercial boiler in the NY area, you might be wondering how often it needs maintenance. Unlike smaller boilers, like those used to heat a private home or smaller property, commercial boilers undergo heavy usage and need to be serviced regularly throughout the year to optimize performance.

Professional technicians recommend at least once a year (seasonal) before the heating season starts, as well as ongoing maintenance throughout the course of the year.

So, to further explain what goes into commercial boiler maintenance and why it’s beneficial, below we’ll review:

  • Benefits of commercial boiler maintenance
  • Signs a commercial boiler needs maintenance
  • What’s included in commercial boiler maintenance

We’ll also help you find a trustworthy heating contractor to provide commercial boiler maintenance.

Benefits of Commercial Boiler Maintenance

It’s important to protect your investment and business with commercial boiler maintenance.

Some key benefits of regular maintenance include:

  • Avoiding costly breakdowns: Regular maintenance service visits can catch minor issues before they become large, pricey repairs.
  • Avoiding downtime: Getting your heating system up and running again quickly is critical when a boiler breakdown occurs. Keep in mind that boiler professionals become less available when demand for service increases during the heating season (Oct-March). Additionally, further delays can happen if a part(s) that needs replacing is unavailable and on backorder. Catching issue(s) outside of the heating season (Spring/Summer) during a scheduled maintenance visit helps avoid downtime when you need your boiler most.
  • Reducing costs in the long run: A more efficient boiler means lower utility bills for your building. It also helps extend your boiler’s lifespan and prevents the need for a sooner than necessary replacement.

Signs a Commercial Boiler Needs Maintenance

These are the major signs you should pay attention to, as they most likely indicate that your commercial boiler needs maintenance soon:

  • Your boiler isn’t properly heating your building despite the pipes and radiators functioning
  • Hearing unusual noises coming from the boiler
  • Your energy bills are increasing despite normal usage
  • You see a drop in pressure levels
  • Your boiler either repeatedly goes on and off (short-cycling) or runs continuously without cycling off
  • You notice water leaking from the boiler or boiler components

Any of these signs are examples of the system not operating properly or even becoming less efficient. A qualified commercial boiler technician will be able to diagnose the cause of your boiler issues and get your system back on track.
