Should I get a generator or a battery?+
Start with what needs to stay on and for how long. A battery's backup duration depends on its charge, capacity, the loads running and any solar available to recharge it. A generator can support extended outages while fuel is available, but it also needs oil checks and maintenance during prolonged use. We size both at the inspection against your priorities. See
home batteries for the other side of it.
What size Generac do I need?+
It depends on what has to run at the same time, not on your house's square footage. The load that decides it for most homes here is the well pump or the air conditioner, because motors draw several times their running current for the first second. Our common whole-home configuration is the 22 kW, which covers most single-family homes in the county including a well. We calculate it at the inspection rather than guessing from a table.
Do I need a transfer switch, or can I just plug it in?+
A permanently installed standby generator requires an automatic transfer switch, and ours is included. This is not upselling — connecting a generator to your house without proper switching can push power back onto the utility lines and injure or kill a lineworker who believes the circuit is dead. It is also what the permit and inspection exist to verify. If you're looking at a portable generator instead, the correct and much cheaper answer is a factory interlock kit at your panel, which we also install.
How loud is it, and will my neighbours mind?+
An air-cooled standby unit is roughly the volume of a running air conditioner, and it exercises itself weekly for a few minutes — that scheduled run is what most neighbours actually notice, and we can set when it happens. On a tight lot, or where an HOA has a view, a sound-reducing enclosure is worth costing out; they carry a lead time of around three months, so it's an early decision rather than a late one. Local noise ordinances and setback rules vary by jurisdiction in this county, and we check yours as part of the permit.
Natural gas or propane?+
Natural gas if you have it — no tank, no refills, but operation still depends on gas service and the generator's maintenance needs. Propane is the answer where there's no gas service, which is a lot of the valley and the ridges. Propane needs a tank sited to code with its own clearances, and a generator burns through it faster than people expect during a multi-day outage, so tank size becomes a real decision rather than a detail. For either fuel, follow the unit's manual for oil checks and servicing during extended outages.
How long does the whole thing take?+
The install itself is one to two days on site. The calendar is usually longer than the labour: permits, the gas check, and inspector scheduling put most projects at two to four weeks from signed quote to commissioned. If your gas meter needs upsizing, that runs on PG&E's timeline and can add weeks — which is exactly why we check it before you sign rather than after.
Is there a tax credit or rebate for a standby generator?+
No. Both federal residential energy credits —
Section 25C and
Section 25D — terminated on 31 December 2025, and neither one covered standby generators even while they existed. Battery storage did qualify under 25D until it expired, so if you've read about a credit in this category, that is probably what you were reading about. We would rather you hear that here than find out at tax time.
Do you service generators you didn't install?+
Yes. Most contractors won't come out for a generator they didn't sell you, and that is how people end up with an expensive unit nobody will look at. We'll service and repair existing Generac installs, and we'll tell you honestly if a unit is past the point where repair makes sense.
