What's the cost of a commercial boiler repair in Queens?

The price of a commercial boiler repair in the Queens/NYC area varies widely depending on:

  • The boiler part(s) that need to be replaced. Some boiler replacement parts cost more than others. For example, the cost to replace a new boiler ignitor switch costs significantly less than replacing a combustion chamber in a commercial boiler system.

What's wrong with my boiler

Your commercial boiler is a complex mechanical system made up of the boiler itself and other components that run throughout your building. At any given time, breakdowns can occur.

The following are some common commercial boiler system issues:

  • Water leaks. As boilers age, they become more prone to leaks. Water leaks can occur anywhere in the system. A leak at the boiler itself is usually more serious than leaks that occur with valves, piping or other components of the system.
  • Uneven Heat (hot and cold spots). Certain areas of your building may receive adequate heat, while other areas may be lacking. In hot water systems, uneven heating issues can sometimes be caused by air trapped inside the system, which requires bleeding the radiators. In a steam system, uneven heating can be remedied by balancing the system with properly-sized air vents, or something as simple as pipe insulation. A bigger issue could be that your commercial boiler is “undersized” (too small) for the heating demands of your building.
  • Strange noises/water hammer. Loud, banging noises coming from your boiler could be caused by a variety of things, including improperly pitched/improperly secured piping, improper boiler control settings, or the absence of water hammer arrestors.

If you’re experiencing these or any other problem with your commercial boiler, we’re here to help. Contact our team anytime for quick, same-day repairs (in most cases).
