A home standby generator should be professionally serviced about once a year. On top of that, the oil and filter need changing after the first 25 hours of run time, and the battery should be replaced every two to three years.
For some NYC businesses, that means life-safety systems, emergency lighting, fire alarm support, access control, sump pumps, servers, refrigeration, elevators, or key HVAC equipment. For others, it may also include tenant-critical systems, communications rooms, security infrastructure, or parts of the building automation system.
