Kohler standby generator and transfer switch — a firehouse installation in Fort Lee, NJ.
For a business, an outage is rarely just darkness. It is spoiled inventory, halted production, dark security and fire systems, servers going down, tenants without heat, and in healthcare, patients without equipment. Standby power is what keeps a facility operating when the grid does not — and it is only worth having if it actually starts under load.
Medical and healthcare facilities, data centers and server rooms, manufacturing plants and cold storage, grocery and food service, banks and financial offices, multifamily and apartment buildings, schools and municipal buildings, and any facility running critical life-safety systems. As a registered NJ public works contractor, we also handle generator projects for public agencies.
Our service department installs and maintains home standby generators across North Jersey — permanently installed units that start automatically when the power fails, not portables you have to drag out in a storm.
Home standby units generally run from around 7,000 to 22,000 watts:
Sizing is a calculation, not a guess: what you need to run, what the starting loads are (well pumps and air conditioning compressors draw far more at startup than while running), and what fuel is available. We will tell you honestly when the smaller unit is the sensible purchase.
A generator, a transfer switch, a concrete or composite pad, an electrical connection to your panel, and a fuel connection — natural gas where available, otherwise propane. It requires permits and inspection, plus coordination with your gas utility or propane supplier. Placement matters too: code-required clearances from windows, doors, and property lines determine where the unit can actually go.
A generator is an engine that sits idle for months and is then expected to start instantly and carry full load. Without maintenance, that is exactly when they fail — and you find out during the storm.
Standby generators need service at least annually. Our maintenance contracts cover oil and filter changes, battery testing and replacement (batteries are the single most common cause of a no-start), fuel system inspection, transfer switch testing, exercise cycle verification, load testing, and control and alarm checks.
We also service and repair units regardless of who installed them, handle warranty work, and provide emergency response when a generator fails at the worst possible moment.
At minimum annually. Commercial units and those in critical facilities typically warrant semi-annual service, and code-required emergency systems have their own testing obligations. Most units also run a weekly self-exercise cycle — if yours has gone quiet, that is worth investigating.
Natural gas is the common choice where a gas line is available — no fuel storage, no refueling, no fuel degradation. Diesel is typical for larger commercial installations and where run-time independent of the gas utility matters, but it brings fuel storage, testing, and polishing requirements. Propane serves homes without natural gas service.
It depends on the unit and your loads. Many homeowners find an essential-circuits generator is the better value — heat, refrigeration, water, and key outlets for a fraction of the cost of whole-house capacity. We will run the numbers both ways.
