Mobile's Complete Generator Installation Solutions
Whole-Home Standby Generator Installation
A whole-home standby generator is the gold standard for Gulf Coast power resilience. Sized to your home’s actual load, fueled by natural gas or propane, and wired to start automatically the moment the grid drops, a properly installed standby keeps your AC, refrigeration, and well pump running through outages most neighbors will sit out in the dark.
- Certified Generac® dealer: factory-trained on the full Guardian and protector residential lines
- Permitted and inspected: every install pulled to current Alabama electrical code
- Concrete pad and proper clearances: set for Gulf Coast wind, drainage, and salt-air conditions
- Commissioning and load test included: we don’t leave until the unit transfers cleanly under load
Generator Sizing & Load Assessment
The single biggest mistake in residential generator installation is buying off the shelf without sizing the unit to the home. Undersized units trip and shorten their service life; oversized units waste fuel and money. We start every project with a free, no-obligation load assessment so the standby generator you put in is the one your home actually needs.
- In-home electrical load survey: every circuit reviewed, not estimated
- Critical-load vs. whole-home options priced side-by-side: you choose the comfort level
- Fuel source consultation: natural gas, LP, or dual-fuel options compared
- Future-proofing review: EV chargers, heat pumps, and solar tie-ins factored in.
Transfer Switches & Code-Compliant Wiring
A generator is only as good as the transfer switch behind it. We install automatic transfer switches (ATS) that detect the outage, isolate utility power for line-worker safety, and bring your generator online — all in seconds. Every install is permitted, inspected, and pulled to current Alabama electrical code so your insurance and warranty stay intact.
- Service-rated ATS installation. eliminates a separate disconnect and tightens the install
- Sub-panel wiring for critical-load configurations. when whole-home isn’t the right fit
- Surge protection integration. protects sensitive electronics during transfer
- Permits, inspections, and final sign-off handled. you don’t chase paperwork

Serving Mobile and Surrounding Communities
Professional Systems installs generators across Mobile, AL and the surrounding Gulf Coast — including Daphne, Spanish Fort, Saraland, Semmes, Theodore, and Tillman’s Corner. We work in established neighborhoods near Spring Hill, in newer construction along the I-10 corridor, and in waterfront homes along Mobile Bay where hurricane-season power loss is a near-annual reality. Every service area presents its own permit office, soil conditions, and fuel-supply quirks — and we know them.
We’re locally owned, headquartered at 216 E I-65 Service Rd in Mobile, and one phone call gets you a real person, a real site visit, and a real quote — not a call center. Your home generator install is project-managed by the same electrician who designs it.

Trusted by Gulf Coast Homeowners
“They diagnosed a power issue that other companies weren’t able to. They determined it was a power company issue, so they called them- seemed to have the inside track, because power company came out within an hour. The technician was extremely knowledgeable and professional, and explained everything very well. Also, I called them at 8 at night and got a human being on the phone! Will use again and recommend to friends.”
— Laura Boatright, Mobile, AL
— Gary Smith, Saraland, AL
“This company is top notch. Not only did they come after hours , but also at the height of a terrible storm. The technician had my generator back up and running in no time. I highly recommend them.“
— Mary Snow, Mobile, AL
Generator Installation Questions, Answered
Have questions about our generator installation services in Gulf Coast Cities? Find answers to the most common questions below.
Generator installation pricing depends on three things: the size of the unit, the fuel source, and the complexity of the transfer switch and wiring. A typical whole-home standby generator install in the Mobile area runs as a project, not a flat fee — which is why we offer a free, no-obligation site visit and written estimate before any work begins. Call (251) 680-7500 to schedule yours.
Yes. Our electrical division runs 7-day-a-week dispatch with after-hours coverage for generator service calls — if your standby generator throws a code, fails to start, or won’t transfer to load, we can get a licensed technician on-site quickly. Call our main line at (251) 680-7500 to reach dispatch.
That depends on the loads you want to keep running during an outage. A “critical-load” install (HVAC, fridge, well pump, a few outlets) typically calls for a smaller unit than a true whole-home standby generator that runs everything. We start every home generator install with a free in-home load assessment so the unit you buy matches the home you actually live in.
Yes. Professional Systems is a certified Generac® dealer, and our electricians are licensed, bonded, and insured in the state of Alabama. Every install is permitted, inspected, and commissioned to current code — and your manufacturer warranty is registered in your name. Ask us about our 1-year workmanship guarantee on the install itself.
