When the grid goes down on the Gulf Coast, your house doesn't have to. Whole-home standby generators sized, installed, and serviced by licensed electricians — installed to code, guaranteed for a year.
Call (251) 680-7500Everyone in Mobile has a hurricane story, and most of them include the days after — no air conditioning in September heat, a freezer full of spoiled food, sump pumps dead when the rain keeps coming. A whole-house standby generator ends that story: it senses the outage, starts itself within seconds, and carries your home — AC included — until utility power returns.
We do this work every week. Recently it was a 25kW whole-home Generac in west Mobile. Before that, a big standby system for a vacation rental down in Gulf Shores. And every September the phone fills up with the same call — “generator won't start” — from Theodore, Fairhope, Satsuma. Nine times out of ten it's a unit nobody's touched since the day it went in. Professional Systems is a certified Generac® dealer, and generator installation is where our two licenses earn their keep. A standby installation is an electrical project (transfer switch, panel work, code compliance) wrapped around a mechanical one (pad placement, fuel connection, load management for your HVAC). We're licensed for the whole scope — no subcontractor handoffs, one crew, one warranty conversation.

The right generator is a math problem, not a sales pitch. We run a load calculation on your actual home — air conditioning tonnage (the big one in Mobile), water heating, well or sump pumps, kitchen, medical equipment — and spec the kilowatt rating that carries what matters without paying for capacity you'll never use.
Fuel matters too: most of our installations run on natural gas where service is available, with propane as the standard alternative farther out. We handle the coordination either way.
Generac's own guidance, translated for Gulf Coast homes: size to your peak electrical load, not your square footage — and let load management do the heavy lifting.
Sizing guidance and product specifications per Generac. Your exact number comes from our free on-site load calculation.
Your real loads, measured — so the unit fits the house instead of the brochure.
The brains of the system, installed at your panel: it senses the outage, starts the generator, and switches your home over in seconds — no extension cords, no flipping breakers in the rain.
Set clear of openings and property lines per code, anchored for hurricane-zone wind, with clearances that keep the warranty and the inspector happy.
Gas coordination and every electrical termination handled by our own licensed team — the part of the job where cut corners hide.
City of Mobile and Mobile County permits pulled, inspections passed, paperwork in your hand. Included, not extra.
We commission the unit under load, register your Generac warranty, and show you exactly how the system behaves before we leave.
After the install, the system exercises itself weekly and reports issues before storm season finds them — and the same local team that installed it services it. See our broader generator installation service for repairs and maintenance too.

Installed cost comes down to four things: the generator's kilowatt size, the transfer switch configuration, the gas work your property needs (existing natural gas line vs. new run vs. propane), and the condition of your electrical panel — older panels sometimes need an upgrade to accept a transfer switch cleanly.
Standing offer: $500 off whole-house generator installation, and every estimate includes a complimentary home electrical safety inspection — claim it with the form above or mention it when you call.
We quote the whole scope up front — unit, switch, pad, gas, electrical, permits — as one exact installed price in writing, with financing options that turn storm security into a monthly payment. When hurricane season is on the horizon, ask about lead times: demand spikes after the first named storm, and the calm months are the smart time to install.
Official Generac overview — 26 seconds.
Every system we install can include Generac's Mobile Link™ remote monitoring — see your generator's status, get maintenance alerts, and confirm its weekly self-test ran, all from your phone. When a storm is inbound and you're not home, that green checkmark is worth a lot.
The map tells the story: generator work from Citronelle and Satsuma down through Theodore and Grand Bay to Gulf Shores — and across the state line into Lucedale and Vancleave, Mississippi. We've installed standby power across every kind of property the Gulf Coast has: raised homes in Midtown where pad placement takes planning, waterfront properties on Dog River and the Eastern Shore where salt air drives enclosure and maintenance choices, and businesses along Airport Boulevard that can't afford a dark storefront. Hurricane-zone anchoring, flood-aware placement, and code clearances aren't special requests here — they're the default spec.
Professional Systems is headquartered at 216 E I-65 Service Rd N and serves the full metro: Mobile, Prichard, Saraland, Semmes, Theodore, Tillmans Corner, and across the bay in Daphne, Spanish Fort, and Fairhope.

— David Atchison, Google reviewIt depends on the kilowatt size your load calculation calls for, the transfer switch configuration, the gas work your property needs, and the condition of your electrical panel. We quote the entire scope as one exact installed price in writing after a free in-home assessment — and financing is available.
Yes — Professional Systems is a certified Generac® dealer serving Mobile and Baldwin County. That means factory-backed equipment, installation to Generac's specifications (which is what keeps the warranty valid), and warranty service that runs through our local office.
For most Mobile homes, whole-home coverage including central air lands in the 18–26kW range — but the honest answer comes from a load calculation, not a rule of thumb. Air conditioning is the dominant load here, and we're HVAC-licensed too, so we size around your actual system rather than a guess.
Typically within about 10 seconds. The automatic transfer switch senses the outage, starts the generator, and switches your home over on its own — whether you're home or not. When utility power returns, it switches back and shuts itself down.
Where natural gas service exists, it's usually the answer: no tank to refill and effectively unlimited runtime. Properties without gas service run on propane with an appropriately sized tank. We handle the coordination for either, including new gas line runs when needed.
Most residential whole-house installations are completed in one to two days on site, once permits and equipment are in hand. Lead times stretch after named storms — the off-season is the smart time to schedule.
Yes — standby generator installations require electrical (and typically gas) permits and inspection in the City of Mobile and Mobile County, plus code-compliant placement and hurricane-rated anchoring. We pull the permits and see the job through inspection as part of every installation.
The unit self-tests weekly on its own. Beyond that, annual service — oil, filters, battery, and a checkup before hurricane season — keeps it ready and keeps the warranty intact. The same local team that installs your generator maintains it.
Usually yes. Occasionally an older or full panel needs an upgrade to accept the transfer switch cleanly — we evaluate that in the free assessment and quote it up front if it applies, and we do that work in-house too.
