Before it is a machine, a standby generator is an electrical system: a transfer switch, a fuel line, a manufacturer-approved base, a Town of Windsor permit and a SAFEbuilt inspection, all of which have to line up around one unit. Thirty years in Northern Colorado, factory-trained and an authorised Generac dealer — and the system is sized from your load, not from a catalogue. Call 970-593-3190.
Why Windsor Homes Lose Power
Windsor sits in the same wind corridor that runs down the Front Range, where downslope windstorms and microbursts have repeatedly taken out lines and cut power to whole neighbourhoods at once. Those events do not schedule themselves: they arrive on a Tuesday afternoon or at two in the morning, and restoration can run from hours to a couple of days.
A standby generator answers that risk with a permanent, automatic system. When utility power drops, the transfer switch disconnects your house from the grid and the generator starts on its own, whether you are home or not.
Standby vs. Portable
A portable is something you wheel out, fill and plug into. A standby is wired into the house through an automatic transfer switch and draws its fuel from what already arrives at the property. Wattage is not the distinction that matters; presence is — one of them needs you at home when the lights go out.
Without proper transfer equipment a portable is also the wrong way to keep a furnace or a well pump alive in a winter outage: back-feeding a panel with a suicide cord is both a hazard and a code violation.
Generac Systems We Install
We are an authorised Generac dealer and install both air-cooled and liquid-cooled home standby systems, matched to what the house actually carries. Factory training covers specification, installation and the maintenance that follows.
Service is not limited to what we installed: we work on all brands, so a system put in by another company still has someone to call.
The Transfer Switch Is the Real Decision
The generator produces power; the transfer switch decides where it goes. A whole-home switch carries the full panel, which means nothing has to be moved by hand during an outage — as long as the unit is sized for that load or load management sheds the biggest circuits while it runs. An essential-circuits switch covers a chosen list instead: furnace, refrigerator, well pump, a few lights, for less money.
The right choice follows the service size, the appliance list and how the household actually lives — none of which can be read off a photo of the meter.
Natural Gas vs. Propane
Natural gas in Windsor comes from Xcel Energy, so a gas unit needs no tank and no deliveries. Propane applies where gas service does not reach the property or the existing line cannot carry the added load, and it needs a tank sized to the runtime you want.
More of the project’s cost is decided by fuel than by the badge on the unit, and it is settled at the survey, before anything is ordered.
Permits and Code in Windsor
A generator installation is permitted work in Windsor: electrical for the transfer switch and connections, and mechanical or plumbing for the gas line where one is extended. The Town of Windsor issues the permits, and inspections run through SAFEbuilt at 970-674-1036.
The Town adopted the 2024 I-Codes effective January 1, 2026, which set the clearance, exhaust-distance and fuel-gas requirements for current work. The electrical requirements come from the NEC edition the Town has adopted, and the permit office confirms that edition when the permit is pulled. Precision Service Electric pulls the permits and coordinates the inspection; a passed inspection is the record that the installation is compliant.
Our Installation Process, Step by Step
Everything starts at the site: where the unit fits, the distance to the gas meter and the panel, the clearances the code requires, and where the exhaust goes. The load calculation then sets the unit size and the transfer-switch choice.
Installation covers the base, the generator, the gas line, the transfer switch and the wiring between them, ending with a live transfer test so you watch the system work before we pack up. The inspection follows, then a walkthrough of the controller and the service schedule.
Maintenance and Repair After the Install
A standby generator is an engine that idles for months and then has to carry a house. Oil, filters, plugs, battery and an annual load test are what keep that promise. Generac systems and other brands, including units another company installed.
What a Generator Costs in Windsor
Published local figures frame the range. MSI Mechanical lists total installed cost for residential standby generators at $7,500 to $18,000+, and Three Crowns Electric advertises a $14,000 average for whole-home installs in Windsor. Those are their numbers, not a Precision Service Electric quote.
What moves the price: generator size, whole-home versus managed transfer switch, natural gas versus propane and tank size, distance from the meter and the panel, pad and clearance work, and permit fees. A quote that arrives before the site survey is a guess.
Serving Windsor and Northern Colorado
We install and service generators throughout Windsor — Water Valley, Pelican Lakes, RainDance, Highpointe and the 80550 ZIP code — and across the communities we serve from our Loveland shop: Fort Collins, Loveland, Berthoud, Johnstown, Greeley, Longmont, Firestone, Timnath, Severance and Eaton. The full list is on our service area page.
For the same service in the next city up, see generator installation in Fort Collins. Generac equipment and maintenance detail lives on our Generac page, and where the service cannot carry the new load we handle panel replacement in Windsor.
“Awesome experience from scheduling, to estimation, to installation! Corey got here right on time, and was already cutting drywall and getting to work within 10 minutes! Not only that, he seems very passionate and knowledgeable about his work- taking time to teach us new homeowners some things we didn’t know about our house. We will definitely use them again and recommend them to anyone! Our project even came in under estimate! Thanks PSE!”

Frequently Asked Questions
Do I need a permit for a standby generator in Windsor?
Yes. The transfer switch and the connections are permitted electrical work, and a gas-line extension is permitted separately. The Town of Windsor issues both permits; inspections run through SAFEbuilt at 970-674-1036, against the 2024 I-Codes the Town adopted effective January 1, 2026.
How much does a generator installation cost in Windsor?
Two local companies publish numbers: MSI Mechanical lists $7,500 to $18,000+ installed, and Three Crowns Electric advertises a $14,000 average for whole-home installs in Windsor. Both are theirs, not ours. Where a particular house lands depends on size, transfer-switch type, fuel, distance from the meter and permit fees.
Will a standby generator run my whole house?
It can, if the unit and the transfer switch are sized for the whole panel. Many households are better served by a managed switch that carries the furnace, refrigerator, well pump, some lighting and a few outlets — lower cost, and no behaviour change during an outage.
How long does the power stay out before the generator starts?
The switch detects the loss and starts the unit automatically, usually within seconds, then closes onto the house once output is stable. It runs until utility power is back and transfers home on its own.
Natural gas or propane?
Xcel Energy supplies Windsor’s natural gas, so a gas-fired unit needs no tank and no refuelling. Propane is the alternative where gas service stops short of the property or the line cannot carry the additional load.
Do you service generators you did not install?
Yes — all brands, including systems another company installed: maintenance, repair and load testing.
How often does a standby generator need service?
At least annually: oil and filter, plugs, battery condition and a load test. A machine that sits idle for months is precisely the one that fails on the first cold night if nobody has looked at it.
