How long does a generator installation take from start to finish?

The physical generator installation is usually the shortest part of the process. Once permits are approved and the equipment is on site, most residential installations, including pad work, electrical connections, transfer switch wiring, and fuel line work, are completed in a concentrated window of a day or two for a typical home. The full timeline from your first consultation to a commissioned, inspected system generally runs longer, because permitting timelines, inspection scheduling, and utility coordination are controlled by outside parties. Complex sites, panel upgrades, or new gas service can extend it further. StandTech Electric gives you a realistic timeline at the proposal stage based on your specific jurisdiction and scope, and we keep you updated as each milestone clears rather than leaving you to wonder where things stand.

What size generator do I need for my home?

Correct sizing depends entirely on what you want running during an outage, and it is the single most important decision in a generator installation. A system covering essential circuits, meaning your refrigerator, furnace or boiler controls, sump pump, well pump, and some lighting, requires far less capacity than a whole-home system running central air conditioning, an electric range, and every room at once. Sizing also has to account for inrush current, the brief surge that motors draw at startup, which can be several times their running load. This is why the 80 percent rule matters: a generator should not be continuously loaded past roughly 80 percent of its rated capacity, because sustained operation near maximum accelerates engine wear and shortens equipment life. Our electricians perform a full load assessment before recommending any unit so your generator operates comfortably within its designed range.

Can I just plug a generator into my house during an outage?

No, and this is genuinely dangerous rather than merely against the rules. Connecting a generator to your home without a transfer switch, whether through an outlet or directly into the panel, can cause backfeeding, where electricity travels backward through the utility lines. Backfeeding can energize lines that utility crews believe are dead, and it can cause fires and equipment damage inside your own home. It also violates electrical code. A permanent generator installation requires an automatic transfer switch, which physically disconnects your home from the utility grid before the generator supplies any power and reconnects only after utility service is confirmed stable. There is no compliant shortcut around this component, and any contractor willing to skip it is not one you want touching your electrical system.

Should I repair my existing generator or replace it?

It depends on age, service history, and whether the unit still fits your home's electrical demand. Generators are engines, and like any engine they reach a point where accumulated repair costs exceed the value of the machine. If your unit is well past a decade of service, requires repeated service calls, fails its scheduled exercise cycles, or was sized for a home you have since expanded with an EV charger, a heat pump, or a finished basement, replacement is often the better long-term decision. If the unit is otherwise healthy and the issue is a battery, a controller, a transfer switch fault, or a wiring problem, repair usually makes more sense. StandTech Electric evaluates the existing system, explains what we find, and gives you an honest recommendation rather than defaulting to whichever option is larger.

What kind of maintenance does a standby generator need after installation?

Standby generators are designed to sit idle and then perform flawlessly on demand, which is exactly why maintenance matters. Most units run a scheduled self-exercise cycle to circulate oil and keep the engine ready, and that cycle is set during commissioning. Beyond that, generators need periodic oil and filter service, battery inspection and eventual replacement, air filter and spark plug attention on the manufacturer's interval, and a general check of the transfer switch, connections, and enclosure. Batteries are the most common cause of a generator failing to start when needed, which is why they are worth checking rather than assuming. As a full-service electrical contractor, StandTech Electric can address not only the generator itself but any panel, wiring, or transfer switch issue contributing to a problem, so you are not coordinating between multiple companies to solve one fault.

WHAT OUR CLIENTS ARE SAYING

Walter C.

HAPPY CLIENT

I had Standtech work on two projects for me. I found the price quoted highly competitive with others I sought estimates from. Both of the project I contracted with Standtech for were completed on time and on budget. The work was performed as specified and those who did the work arrived on time, went about their business in highly professional manner, completed the work to my satisfaction and left things neat and clean. I was very satisfied with the work Standtech did on the two projects I hired them for and wouldn't hesitate to hire Standtech again.

What a Generator Installation Actually Protects You From

An outage is rarely just a dark house. It is a sump pump that stops running in the middle of a storm. It is a freezer full of food on a clock. It is a home office that goes offline in the middle of a workday, a well pump that stops delivering water, a medical device running down its battery, and pipes that get colder by the hour in January.

A properly installed standby generator removes that entire category of problem from your life. The unit monitors your utility feed continuously. When the power drops, it starts automatically and transfers your home over, typically within seconds. You do not run extension cords, you do not haul fuel cans, and you do not have to be home for any of it to work. When utility power returns, the system transfers back and shuts itself down on its own.

That is the real product here. Not a machine in the side yard, but the ability to stop thinking about outages altogether.

What's Included in a Generator Installation From StandTech Electric

Generator installation is a multi-trade project, and gaps between trades are where most problems start. Our team manages the full scope in house so nothing falls through:

On-site power load assessment. We calculate what you actually need to run, including startup surge from air conditioning compressors, well pumps, and other high-draw equipment, so the unit is sized against real demand instead of a guess.
Equipment selection guidance. We walk you through generator options based on your load profile, available fuel, site constraints, and budget, then explain the tradeoffs in plain language.
Permitting and inspection coordination. We prepare and file the required permits and see the project through inspection so you are not interpreting building code on your own.
Code-compliant placement. Setback distances from walls, windows, vents, and property lines are dictated by fire and building code. We site the unit correctly the first time.
Automatic transfer switch installation. This is the safety component that isolates your home from the utility grid before the generator energizes anything.
Fuel line coordination. Natural gas or propane, including verification that your existing gas service can support the added load rather than assuming it can.
Electrical panel integration. If your panel cannot cleanly accommodate the new circuits, we tell you before the project starts, not after the generator is on site.
Commissioning, load testing, and a full walkthrough. You will know how your system operates, how to read it, and what its maintenance rhythm looks like before we leave.

Generator Brands We Install and How the Right One Gets Chosen

There is no single best generator, only the right generator for a specific house, a specific electrical load, and a specific fuel situation. StandTech Electric installs and services a range of manufacturers so the recommendation is driven by your home rather than by whatever a company happens to stock:

Generac

The most widely installed residential standby line in North America, with a broad range of capacities and a mature remote monitoring ecosystem.

Kohler

A long-established name in residential standby power, frequently specified where sound level and enclosure quality are priorities.

Cummins

Known for engine engineering, with home standby units drawn from a deep commercial and industrial background.

Briggs & Stratton

A legacy engine manufacturer with a home standby lineup built around straightforward serviceability.

FranklinWH

A whole-home energy management and battery storage platform that can be configured to work alongside a generator, giving homeowners layered backup rather than a single point of failure.

During your consultation, our generator installation experts compare capacity, fuel type, physical footprint, noise output, monitoring features, and long-term parts availability against what your property can support. You get a recommendation with reasoning attached.

Your Generator Installation, Step by Step

Knowing the sequence removes most of the anxiety from a project like this.

1. Consultation and load assessment. We walk the property, review your panel, and determine whether you want essential-circuit coverage or a whole-home system. This is where the correct size gets established.

2. Proposal and equipment selection. You receive a scoped estimate with the unit, the transfer switch, the electrical work, the fuel work, and the site preparation broken out so you can see what you are paying for.

3. Permitting. We prepare and submit the required documentation and coordinate with the relevant utility and municipal authorities.

4. Site preparation. Pad work, clearances, and any landscaping or grading adjustments needed to meet code and keep the unit accessible for future service.

5. Installation. Generator set, transfer switch wiring, panel integration, and fuel connection. Most physical installations are completed in a short, concentrated window once materials and approvals are in hand.

6. Inspection, commissioning, and walkthrough. The system is tested under load, inspected, and handed over with a clear explanation of exercise cycles, maintenance intervals, and monitoring.

Signs Your Home Is a Strong Candidate for Generator Installation

Some households benefit from backup power more than others. You are likely in that group if any of the following apply:

Your basement depends on a sump pump and you live where storm flooding is a real possibility
Someone in your home relies on powered medical equipment, climate control, or mobility devices
You work from home and cannot absorb hours or days of downtime
Your water comes from a well, which means no electricity equals no running water
You have had more than one multi-day outage in recent years
You have already lost a refrigerator or freezer full of food to an outage
You have added significant electrical load recently, such as an EV charger, heat pump, or finished basement
You own an existing generator that is aging, failing test cycles, or no longer sized for your current demand

Pairing Generator Installation With Battery Storage

Most electrical contractors install generators. Fewer can speak fluently about how a generator, a battery system, and your panel behave together as one coordinated system.

StandTech Electric works across the full backup power landscape, including battery energy storage systems, Tesla Powerwall, Anker SOLIX, and FranklinWH. That matters because the two technologies solve different halves of the same problem. A battery covers short interruptions instantly and silently, with no fuel consumption and no engine noise for a brief blip. A generator carries long-duration outages that would drain a battery, running as long as fuel is available.

Configured together, they cover both ends of the spectrum. If that layered approach interests you, our team can model how it would work on your home during the same consultation as your generator installation. If a generator alone is the better fit for your situation, we will tell you that too.

What Drives the Cost of a Generator Installation

Generator installation pricing varies significantly from home to home, and any contractor quoting a firm number before seeing your property is guessing. The variables that genuinely move the price include:

The capacity of the unit, which is determined by your load assessment
Whether you are covering essential circuits or the whole home
The distance between the generator location and your electrical panel
Whether new gas line work, a meter upgrade, or a propane tank is required
Site preparation, including pad work, access, drainage, and clearance corrections
The condition and capacity of your existing electrical panel
Permit and inspection fees, which vary by jurisdiction

StandTech Electric provides free, itemized estimates so you can see how each of those factors affects your total. We would rather explain a number you understand than advertise one you cannot rely on.

Why Homeowners Choose StandTech Electric for Generator Installation

Generator installation sits at the intersection of electrical work, gas work, concrete work, municipal permitting, and utility coordination. The contractor you choose needs to be credible across all of it.

StandTech Electric has been operating since 2013 with a team carrying more than 25 years of hands-on electrical experience, and we hold master electrician licensing and full insurance. We are backed by Authority Brands and its national support network, which gives a locally run team access to resources most independent contractors do not have. Our electricians are experienced, courteous, and drug-tested, and we offer 24/7 emergency service for the times when waiting until morning is not an option.

We also do not hand the important parts of your project to someone else and hope it goes well. Our team manages the permitting, the utility coordination, and the installation itself. Clients consistently describe the experience the same way: organized, communicative, clean, and straightforward about options and costs. One homeowner summarized a whole-house generator project by noting that we handled everything from selecting the right unit through final permits. That is the standard we hold ourselves to on every installation.

What Ownership Looks Like After the Install

A correctly sized unit runs within its designed operating range, which means lower fuel consumption, less engine wear, and a longer service life than an undersized generator pushed to its limits every outage. A properly permitted and inspected installation means no complications when you refinance, sell, or file an insurance claim. And a system installed by a full-service electrical contractor means that when you eventually need service, a panel upgrade, or an addition to your backup capacity, you are calling a team that already knows your setup.

Beyond the technical, there is the part that is harder to quantify. Storm forecasts stop being stressful. You stop moving food to a neighbor's freezer. You stop pricing hotel rooms in February. The house simply keeps running.
