Do I need a permit for a whole-home generator in Lexington, KY?

Yes. Local codes require a permit for the electrical work and, in most cases, a separate gas permit if you're tying into a natural gas line. We handle the filing and coordinate the inspection so you're not the one chasing down the county office.

Can you install a generator I already purchased?

Only if it's a Generac unit purchased through an authorized dealer like us. We don't install generators bought from other retailers or private sellers. It's not about being difficult. Warranty coverage and the manufacturer's safety certification both depend on authorized-dealer installation, and skipping that step can void protections you're counting on.

What size generator do I need for my home?

It depends on what you want covered. A generator sized to run your whole house, including the HVAC system, is a bigger unit than one meant to keep the essentials going: refrigerator, well pump, a few lights, and anything running medical equipment. We do a load calculation on-site instead of guessing off square footage, since two homes the same size can have very different electrical demands.

Natural gas or propane? Which is better for a Central Kentucky home?

Natural gas is usually the simpler choice if your home already has a gas line, since fuel supply is essentially unlimited as long as the utility is running. Propane makes more sense for homes without gas service, or for anyone who wants fuel stored on-site rather than dependent on the pipeline network. Both run Generac systems reliably. The right call comes down to what's already at the property.

How long will my standby generator installation take?

Most installs take one to two days once the permit is approved, depending on how far the generator is from the panel and whether the gas or propane line needs to be extended. The permit and inspection process usually adds another week or two on the front and back end, so we build that into the timeline when we quote the job.

Will my backup generator start automatically, or do I have to do anything?

It starts on its own. The automatic transfer switch senses the outage, starts the generator, and shifts your electrical system over, typically within about 10 seconds. Most homeowners are in another room when it happens and only notice because the lights barely flicker.

What’s included in a Lexington generator installation service?

What's included in a typical generator installation: Load calculation and generator sizing for your home's electrical needs Automatic transfer switch installation and panel integration Natural gas or propane fuel line connection Concrete or composite pad setup for the unit Permit filing and inspection coordination with local code officials System startup, automatic start testing, and a walkthrough of how it runs We also handle routine maintenance on the systems we install: oil changes, battery checks, and the annual service that keeps a standby generator ready instead of just sitting there. A generator that's never been serviced is a generator that might not start when you actually need it.

How do I schedule a whole home generator installation with Mr. Electric of Central Kentucky?

Whole Home Generator Installation Lexington, KY

Central Kentucky loses power more often than most homeowners realize. Ice on the lines in January, a summer storm rolling through in July, a transformer that finally gives out on an ordinary Tuesday. When the lights go out, the freezer starts thawing, the sump pump stops, and anyone relying on medical equipment at home is suddenly on borrowed time. A Lexington electrician who installs whole home generators every week sees the same pattern: the families who call us after their second or third outage wish they'd called after the first one. Mr Electric of Central Kentucky installs and services Generac whole-home generators for homeowners across the Lexington area. We're an authorized Generac dealer, which means every unit we install is backed by the manufacturer's warranty and set up the way Generac actually engineers it to run. Whether you're weighing a natural gas system against a propane generator or you just want to know what a proper automatic transfer switch costs installed, we'll walk the property with you and give you a straight answer.

Our Process for Whole Home Generator Installation: Lexington, KY

A Lexington electrician who's installed dozens of these systems will tell you the generator itself is rarely the hard part. Sizing it correctly, tying it into your electrical system safely, and setting up the transfer switch so it works the moment the power drops is where the job actually happens. That's the part we've spent years getting right. Our installation process starts with a load calculation, not a guess. We walk through the home, note which circuits matter most (well pump, HVAC, refrigerator, medical equipment, security system), and size the whole-home generator to cover them without oversizing the unit and the bill that comes with it. From there, we handle the fuel connection, whether that's tying into your existing natural gas line or setting up a dedicated propane tank, and we pull the permits Lexington and Fayette County require before any work starts.
The automatic transfer switch is the piece most homeowners underestimate. It's what detects the outage, starts the generator, and switches your home's electrical system over automatically, usually within about 10 seconds, with no one home to flip anything by hand. We size and install automatic transfer switches to match your panel and your generator's output, and we test the automatic start function before we consider the job finished.
Lexington, KY homeowners will be happy to hear that we're a Generac dealer, and we install Generac Power Systems units purchased through us. Authorized dealer status is part of how the warranty and the safety certification hold up, and we're not willing to cut that corner for anyone.

Why Lexington Homeowners Choose Mr. Electric for Whole Home Generator Installation

Our Lexington electricians average 10 years in the trade, and generator installs make up a real share of that experience, not a side skill someone picked up last year. We're licensed, we pull the proper permits, and we don't shortcut the parts of the job that inspectors actually check: grounding, bonding, and transfer switch wiring.

Voltage fluctuations from an aging local power utility grid can be just as disruptive as a full outage, and we size systems with that in mind rather than the bare minimum. If a storm knocks out power for six hours or six days, your home standby generator doesn't know the difference. It just runs.

Beyond generators, we're a full-service electrical company. Main panel upgrades, complete service changes for older homes that need a full rewire, EV charger installation, and home safety checks are all work we do regularly, not occasional add-ons. If your panel can't support a new generator without an upgrade first, we can handle both in the same visit instead of sending you to a second contractor.

Ready to stop worrying about the next outage? Call Mr Electric of Central Kentucky, and we'll schedule a time to walk your property and talk through sizing, fuel type, and cost before you commit to anything.
