What standby generator installation involves, start to finish
A home standby generator sits outside on a pad and starts by itself through an automatic transfer switch (ATS) when utility power drops. When power returns, the switch moves the house back and the generator shuts down. A typical install runs in this order:
- A site visit and load calculation to size the unit (sizing guide)
- Choosing a spot that meets code and manufacturer clearances
- Permits, plus any gas meter or electrical service upgrade
- Pad, gas line and transfer switch installation
- Inspection, startup and a simulated outage
Before the site visit, write down what has to run during an outage: furnace, fridge, well pump, sump pump, central air, any medical equipment. Find your gas meter and electric panel, and check your HOA rules if you have one. That list turns a vague estimate into a real one.
The on-site work is the short part. Permits, equipment and utility work set the calendar, which is why the best time to start is well before the next ice storm. If you already have a brand in mind, see Generac generator installation or Kohler generator installation.
Natural gas vs propane for a standby generator
Most homes in Capital District cities and suburbs have natural gas, and that's the easy choice: the utility keeps it flowing and there's no tank to refill. Rural homes without gas service run on propane, which means a tank on site.
| Natural gas | Propane | |
|---|---|---|
| Supply | From the utility, no refills | Tank on site, refilled by a supplier |
| Extra install work | Possible meter upgrade | Tank placement and a line from the tank |
| Best fit | City and suburban homes | Rural homes, farms and camps |
With propane, tank size is the real question. A long outage after an ice storm burns through fuel, so size the tank for the outage you're worried about, not the average one. In places like Brunswick, with rural lots and longer runs from the tank to the house, the line itself becomes a real part of the job. Also note that rated output often differs between the two fuels, so check the rating for the fuel you'll use.
Gas meter and electrical service upgrades
A standby generator burns a lot of gas at full load, on top of your furnace, water heater and range. If the existing meter can't supply all of it, the installer coordinates a meter upgrade with National Grid or your gas utility. It's common enough that a good installer checks for it at the first visit.
On the electrical side, older homes sometimes need panel work before a transfer switch goes in: a full panel, an outdated panel, or a service that doesn't match what the switch requires. Better to find that at the site visit than on install day.
Placement, HOA approval and generator noise
Placement balances four things: code and manufacturer clearances from windows, doors and vents; a short run to the gas meter and electric panel; noise; and what the neighbors (or the HOA) will accept.
In subdivisions like those around Clifton Park and the Shenendehowa area, the homeowners association may want to approve the location and screening before work starts. Get that approval first. Screening with a fence or shrubs works, as long as it keeps the required clearances and leaves room for service.
Noise is the other placement issue. The unit runs briefly on its exercise schedule even when the power's on, so keep it away from bedroom windows, yours and the neighbor's.
Think about winter, too. A spot under a roof edge that drops ice, or where the plow or snowblower piles snow, buries the unit when you need it most. Pick a spot you can reach and clear in February.
Standby generator vs portable: why the install is worth it
A portable generator needs you home to start it, gasoline on hand, and cords or an interlock run through a window or panel. It must never run indoors or in a garage, because of carbon monoxide. A standby generator does none of that: it starts on its own, whether you're home, asleep or out of town, and keeps the well pump, sump pump and furnace going. For a basement that floods without a sump pump, or a house that loses water when the well pump stops, that's the whole point.
