A standby generator is a permanent electrical system before it is a machine: a transfer switch, a fuel line, a manufacturer-approved base, a City of Greeley permit and an inspection all have to line up around it. Precision Service Electric has been in business in Northern Colorado for three decades, is factory-trained and an authorized Generac dealer, and sizes the system from your actual load rather than from a catalogue page.

Why Greeley Homes Lose Power
Greeley sits on the eastern edge of the same wind corridor that runs down the Front Range, and the storms that arrive here are not gentle: downslope winds and summer microbursts take out lines and can cut power to whole neighbourhoods at once. Restoration runs from hours to a couple of days.
A standby generator answers that with a permanent, automatic system. When utility power drops, the transfer switch disconnects the house from the grid and the generator starts on its own, whether you are home or not — no fuel cans, no extension cords, no guessing which appliance to unplug.
Standby vs. Portable
A portable generator is a device you wheel out, fuel and plug appliances into. A standby generator is wired into your home’s electrical system through an automatic transfer switch and runs on the fuel supply already at the house. The practical difference is not wattage — it is that one requires you to be present, and the other does not.
Portables are also the wrong tool for a furnace or a well pump in a winter outage without a proper transfer arrangement; back-feeding a panel with a suicide cord is both dangerous and a code violation.
Generac Systems We Install
Precision Service Electric is an authorized Generac dealer and installs Generac air-cooled and liquid-cooled home standby systems, sized to the load the house actually carries. As a factory-trained dealer we can specify the unit, install it and maintain it afterwards.
We also service all brands of standby generator, so a system installed by someone else is not orphaned when it needs repair.
The Transfer Switch Is the Real Decision
The generator makes power; the transfer switch decides what receives it. A whole-home transfer switch carries the entire panel, so nothing has to be switched by hand during an outage — provided the generator is sized for that load, or the system includes automatic load management that sheds the largest loads while the generator runs.
A separate arrangement — an essential-circuits switch — carries only a chosen set of loads: furnace, refrigerator, well pump, some lighting. That is not the same thing as whole-home backup with automatic load shedding, and it costs less. Under the code the generator has to be sized for the maximum load the transfer equipment can connect, whichever arrangement is chosen. Which one is right depends on the service size, the appliance load and how the house is used. Nobody can tell you from a photograph of the meter.
Natural Gas vs. Propane
Xcel Energy supplies electricity in Greeley and Atmos Energy supplies the natural gas, so a natural-gas unit never needs a tank, a delivery or a gauge. Propane is the answer where gas service does not reach the house or where the existing line cannot carry the additional load; it requires a tank sized for the runtime you expect and a supplier relationship.
Fuel choice drives the cost of the whole project more than the generator’s badge does. It is settled during the site survey, before anything is ordered.
Permits and Code in Greeley
A generator installation is permitted work in Greeley: electrical for the transfer switch and connections, and mechanical or plumbing for the gas line where one is extended. Permits come from the City of Greeley Building Inspection division at 1100 10th Street, Suite 114 — 970-350-9830, and applications and inspections run through the City’s eTRAKiT portal.
One local rule worth knowing before you schedule anything: the City has published that a contractor licence will be required for permits starting January 1, 2027. Precision Service Electric is licensed and insured under Colorado licence #3918, and the edition of the electrical code the City enforces is confirmed with the permit office when the permit is pulled.
Our Installation Process, Step by Step
The work starts with a site survey: where the unit can sit, how far it is from the gas meter and the panel, what the code requires for clearances, and how the exhaust will vent. Then the load is calculated to size the unit and choose the transfer switch.
Installation sets the pad, sets the generator, runs the gas line, installs the transfer switch, wires the generator to it, and commissions the system — including a live transfer test so you see it work before we leave. The inspection follows, and we walk you through the controller and the maintenance schedule.
Maintenance and Repair After the Install
A standby generator is an engine that sits idle for months and then has to start under load. Annual service — oil, filters, plugs, battery, a load test — is what keeps that dependable. We service Generac systems and other brands, including units installed by other companies.
What a Generator Costs in Greeley
Published figures frame the range rather than fix it. MSI Mechanical, a Northern Colorado company, lists total installed cost for residential standby systems at $7,500 to $18,000+. Equipment-only prices that circulate online describe the box, not the installation — the base, gas line, transfer switch, permits and labour are the rest of the number, and none of it is 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 to the panel, pad and clearance work, and permit fees. A quote that arrives before the site survey is a guess.

Frequently Asked Questions
Do I need a permit for a standby generator in Greeley?
Yes. Electrical work for the transfer switch and connections is permitted, and a gas line extension is permitted separately. Permits come from the City of Greeley Building Inspection division, 1100 10th Street Suite 114, 970-350-9830, and inspections run through the City’s eTRAKiT portal.
How much does a generator installation cost in Greeley?
MSI Mechanical publishes $7,500 to $18,000+ installed for residential standby systems in this region, and equipment-only prices that circulate online exclude the base, gas line, transfer switch, permits and labour. Size, transfer-switch type, fuel, distance from the meter and permit fees decide where a specific house lands.
Will a standby generator run my whole house?
It can, if the unit and transfer switch are sized for the whole panel — or if the system includes automatic load management that sheds the largest loads. Many households are better served by a managed switch carrying the furnace, refrigerator, well pump and some lighting.
How quickly does it start after an outage?
The transfer switch senses the loss and starts the generator automatically, typically within seconds, then transfers the load once the generator is producing stable power. It runs until utility power returns and then transfers back on its own.
Natural gas or propane in Greeley?
Atmos Energy supplies natural gas in Greeley, so a natural-gas unit needs no tank and no deliveries. Propane is used where gas service does not reach the house or the existing line cannot carry the load, and it needs a tank sized for the runtime you want.
Do you service generators you did not install?
Yes. We service all brands, including systems installed by other companies — maintenance, repair and load testing.
How often does a standby generator need service?
Annually, at minimum: oil and filter, plugs, battery condition and a load test. A generator that sits idle for months is exactly the machine that fails on the first cold night if nobody has looked at it.
