Foley homeowners weighing whole house generator installation face a coastal reality: hurricane season runs June through November, and Baldwin Electric Cooperative outages after a Gulf storm can stretch past a week. This guide breaks down what to look for, which generator sizes actually make sense for a Foley home, and what to skip.
TL;DR
Whole house generator installation in Foley, AL means matching a 20kW to 26kW standby unit to your home's electrical load, choosing a licensed installer who pulls permits, and installing before storm season peaks in August and September. A Kohler 20RESA is the safe pick for most 2,500-square-foot Foley homes, while a 26kW Generac Guardian is the right call for larger houses running well pumps and central AC simultaneously. Portable generators are a Skip for anyone who wants true whole-house coverage in 2026.
Why this matters
Foley sits close enough to the coast that grid outages aren't rare weather trivia - they're an annual planning problem. A licensed master electrician sizes your standby generator to your home's actual electrical panel, not a generic square-footage chart, which is the difference between a unit that runs your AC and well pump together and one that trips on overload the first hot afternoon. Baldwin County Generators installs Kohler, Generac, Honeywell, and Briggs & Stratton standby systems across coastal Alabama, and the installation process itself - permitting, gas line sizing, transfer switch wiring - matters as much as the brand name on the unit.
Who this is for
This guide is for Foley homeowners who've lost power for more than a day during a named storm and are done running extension cords to a portable unit in the driveway. It's built for people who want the generator to start automatically within seconds of an outage, run the whole house - not just the fridge and a few lights - and keep doing that for years without babysitting it. If you're comparing a $400 box-store portable against a permanently installed standby system, this is written for the second option.
What to look for in whole house generator installation for Foley
Correct sizing for your electrical load
A generator sized off square footage alone routinely undersizes homes running central AC, an electric range, and a well pump at the same time. A proper installer runs a load calculation on your panel before quoting a kW size - 20kW handles most standard Foley homes, 22-26kW covers larger houses or homes with multiple AC units, and anything smaller than 20kW usually forces you to shed circuits during an outage.
Automatic transfer switch quality
The transfer switch is what senses the outage and flips your home from grid power to generator power, usually within 10-20 seconds. A cheap or mis-sized transfer switch is the single most common cause of a standby system failing to engage when you actually need it, so this isn't a place to cut cost.
Fuel source and line sizing
Most Foley installations run on natural gas or LP (propane), and the gas line has to be sized for the generator's full-load draw, not just "whatever's already there." An undersized gas line will start a generator and then starve it under full load - exactly when a hurricane knocks out grid power and you need every circuit running.
Licensing, permits, and code compliance
Baldwin County and the City of Foley both require permits and inspections for standby generator installation, and flood-zone elevation rules apply close to the coast. An installer who skips the permit step isn't saving you money - they're leaving you with an uninspected gas and electrical system tied to your house.
Maintenance and warranty support
Standby generators need annual service - oil changes, battery checks, a load test - to actually start when a storm knocks out power after sitting idle for eight months. Ask whether the installer offers ongoing maintenance plans or just walks away after the install; the warranty on a Kohler or Generac unit typically requires documented maintenance to stay valid.
Noise and placement
Foley lots often sit close to neighbors, and standby units run in the 60-70 dB range at 20 feet, roughly as loud as a dishwasher. Placement has to satisfy setback codes from property lines, windows, and gas meters, which an experienced local installer will already know cold.
Top picks for Foley homeowners
Kohler 20RESA (20kW) - the safe pick. Handles a standard 2,000-2,800 sq ft Foley home running central AC, a well pump, and kitchen appliances together, with a factory-matched automatic transfer switch. Verdict: Buy for most single-family homes.
Generac Guardian 22kW - the whole-house workhorse. Steps up load capacity for homes with a second AC unit or a larger kitchen, and Generac's dealer network in coastal Alabama makes parts and service turnaround faster than less common brands. Verdict: Buy for larger Foley homes over 2,800 sq ft.
Honeywell 20kW - the budget-conscious option. Comparable output to the Kohler at a lower price point, built on a similar engine platform, though local parts availability can lag the bigger dealer networks. Verdict: Consider if upfront cost is the deciding factor.
Briggs & Stratton 20kW - the wildcard. Solid engine reliability and a straightforward install, but fewer coastal Alabama dealers stock replacement parts on hand compared to Kohler or Generac. Verdict: Consider for homeowners prioritizing engine simplicity over brand ubiquity.
Portable/inverter generator (5,000-10,000 watt) - not a whole-house solution. Requires manual setup during a storm, runs a handful of circuits at best, and needs continuous refueling every 8-10 hours. Verdict: Skip for anyone who actually wants their whole house covered in 2026.
What to avoid
- Undersized units marketed as "whole house." A 10-14kW generator will run lights and a fridge but trips the moment AC and a well pump kick on together - read the actual amp draw, not the marketing label.
- Installers who skip the permit and inspection step. It's faster and cheaper short-term, but it voids manufacturer warranties and leaves an uninspected gas line at your house.
- DIY transfer switch wiring. Backfeeding a panel without a proper transfer switch is a code violation and a genuine safety hazard to utility line workers restoring power after a storm.

FAQ
What size generator do I need for a house in Foley, AL? Most 2,000-2,800 sq ft Foley homes need a 20-22kW standby generator to run central AC, a well pump, and kitchen appliances at once. Larger homes or those with two AC units should size up to 26kW after a proper electrical load calculation.
How long does whole house generator installation take? A typical standby installation in Foley takes 1-3 days once permits are pulled, covering the concrete pad, gas line run, electrical panel work, and transfer switch wiring. Permit approval timelines through Baldwin County can add another 1-2 weeks before install day.
Is natural gas or propane better for a standby generator in Foley? Natural gas works well if your home already has a gas line sized for the load; propane is common for homes on well water without municipal gas service. Either fuel runs a Kohler, Generac, or Honeywell unit indefinitely as long as the supply line is sized correctly.
Do I need a permit for generator installation in Foley, AL? Yes - Baldwin County and the City of Foley both require permits and inspections for standby generator installation, covering the gas line, electrical connection, and pad placement. A licensed electrical contractor pulls these as part of the install process.
How much maintenance does a whole house generator need? Standby units need an annual service visit covering oil changes, battery testing, and a load test to confirm the unit actually starts under real demand. Skipping maintenance is the most common reason a generator fails to start during the storm it was bought for.
Is a portable generator good enough for hurricane season in Foley? No - a portable generator covers a handful of circuits and needs manual setup and refueling every 8-10 hours, which doesn't hold up through a multi-day outage. A standby system starts automatically within seconds and runs the whole house without anyone home.
How loud is a whole house generator? Most standby units run around 60-70 decibels at 20 feet, comparable to a running dishwasher, and Foley's setback codes govern how close a unit can sit to property lines and windows. A licensed installer accounts for this during placement.
When should I install a generator before hurricane season? Install by May if possible - permit approval, equipment delivery, and installation scheduling all get backed up once storm warnings start in June. Waiting until a storm is forecast means competing with every other homeowner in coastal Alabama for the same install slots.
One last thing
The detail most Foley homeowners miss: an oversized generator sitting idle 99% of the year with dead batteries or old oil fails at the exact moment it's needed, so the annual maintenance visit matters more than the kW number on the spec sheet. A 20kW unit maintained every year beats a 26kW unit that hasn't been serviced since 2024.
