Maintenance & Service Plan


Preventative Maintenance (PM) Agreements whether gas or fuel oil burners, are available for almost all equipment starting at 50 HP and up.   Our technicians have years of experience in maintaining water-tube, fire-tube, sectional and furnace bank equipment manufactured by companies such as: Federal, Rockmills, Weil Mclain, Cleaverbrooks, Slantfin, AO Smith and more!  


Our PM program is designed to insure your system operates at peak efficiency throughout the year.  Services include performing a complete full service overhaul of the main combustion system components, ancillary compressors and combustion efficiency test to ensure proper adjustments have been made to maximize operations during low/high fire.   In additions, a monthly plus option is available with each contract in which our technician will perform a monthly control tune up, plus one annual overhaul. 

Service visits are performed by qualified in-house technicians.  Your equipment will be entered into our computerized maintenance system which will create a history file and prompt us to notify you ahead of time when your facilities are coming due for service.  Our 24 hour emergency services will ensure you that your operations will continue to run efficiently throughout the year.

Steam Trap and Vacuum Repairs using thermal imagery testing.   Many facilities produce steam for heating or manufacturing processes. The steam is typically piped from a central boiler(s) to various locations on-site where the steam is used. “Steam traps” are mechanical devices installed on the pipes to remove condensate from the steam flow; they are needed to maintain the proper operation of the steam distribution system. 

A typical industrial plant or university site may have several hundred or even thousands of steam traps.  Unfortunately, steam traps have a tendency to leak, which can add up to thousands of dollars per year of wasted steam for a single steam trap. This was probably less important when the original steam system was built years ago, but with today’s energy prices, it is critical to detect and correct failures quickly. 
On average 15-25% of steam traps are leaking at existing installations, which means hundreds of thousands of dollars of wasted energy per year per site.  At National Grid we will provide a technician (surveyor) to conduct an assessment of the steam traps. Our trained surveyor uses the latest thermal imagery equipment to tag and locate, identify the working conditions and submit a repair log sheet.  
Most utilities will provide the customer a rebate for the repair of the steam trap to encourage energy savings.  Below is a sample of the potential savings that may be realized from leaking steam traps.  



DAR pre-inspections, violation removal, registration renewals and certificate of operations.

By now we are all familiar with the Local Law 62-91 Inspection, which requires a licensed oil burner installer or your insurance company to file the necessary forms with the Building Department.  


DEP also requires for specific boilers registration renewals every 3 years, which is why they’re categorized as triennials.  Local Law 38 of 2015 amended requirements for Boiler Registrations (separate from annual inspections filed with the DOB), and created two categories of registrations.  Boiler Registration I (350,000 BTU/hr to 2.8 mmBTU/hr) Renewal Only and Boiler Registration II (2.8 mmBTU/hr to 4.2 mmTU/hr) which requires a Work Permits/Certificates of Operation.


As a separate fee for service outside our preventative maintenance plan, National Grid Energy Management LLC will perform one of the following services: 

LOCAL LAW                 Inspection and Filing             $250 PER BOILER

DAR/DEP                      Registration Renewal            $195 PER BOILER

DAR/DEP                  Certificate of Operations        $1,100 PER BOILER      

National Grid Administrator will handle all paperwork for the department of Air Resources Triennial Renewal only. Any filing fees, engineering fees, fines etc, shall be paid by owner.  

You will be billed for this fee once you have submitted to us the registration renewal amount required by the State for the Department of Building.  

We will perform a pre-check before the inspection to ensure the equipment meets all the qualifications needed in order to pass the inspection. The pre-check is on a time and material basis. When we receive the inspection date we will notify you and one of our service technicians will meet with the D.E.P inspector at the job site on that day. Any work required to obtain said certificate (triennial), shall be billed at prevailing rates. Any filing fees, engineering fees, fines etc, shall be paid by owner.

It is the building manager’s (customer) responsibility to request LOCAL LAW INSPECTION.  We will not perform any inspection unless it is requested.  Failure to do so will result in fines anywhere from $500 to $1500 per boiler.


We are not responsible for any duplication in filing or be able to replace any lost documents and/or reports.

Notifact is an internet wireless remote monitoring system used by our managing agent, owners and facilities personnel.   The monitoring system is without the use of costly phone lines and will notify key people on your team of any alarm condition that may occur at your facility.   The general-purpose transmitter is part of the Notifact network for wireless monitoring of mechanical equipment.  It can be used to monitor any mechanical failure or alarm specific conditions at your facility. 


This can include:

  • Check oil strainers 

  • Boiler and/or water heating equipment lockout

  • Compressor failure

  • Water spill

  • or Temperature out of limit. 


A key benefit of the Notifact system its multi capabilities to monitor burner safety conditions.    The service will use the Internet to configure who will receive each message regarding the alarm conditions.  Delivery methods include pagers (alphanumeric, numeric), fax, e-mail, PCS or telephone (voice delivery).  If there is a power failure to the device, perhaps indicating a site power problem, an alarm message will be generated.  To verify that the system is operating, every 24 hours, the transmitter will also transmit to the Notifact website a message that the system is properly functioning
