Stay Compliant. Avoid Fines.

Keep Your Building Running Smoothly.

The NYC Department of Environmental Protection (DEP) requires all boilers 350,000 Btu/h to submit a renewed registration or certified combustion test triennially.  This process is separate from annual inspections. Building owners who have boilers equal to or greater than 2.8 million Btu/h must self-maintain five years of records.

Triennial registrations aren’t just paperwork—they’re part of NYC’s clean air regulations. They help the DEP:

  • Track boiler equipment across the city

  • Verify fuel types and capacities

  • Ensure compliance with current emissions standards

Failure to renew your registration before it expires can result in costly violations and fines.

Don’t wait for a violation notice. Contact us today to confirm your boiler registration is up-to-date.
