15 questions every Bradenton homeowner should ask before spending $15K–$30K on a whole-home generator. Sizing, licensing, warranty, storm response — the things that separate a real install from a botched one.
Four specific failure modes show up every hurricane season in Manatee County.
Undersized, badly sited, or never-maintained generators fail at exactly the moment you need them. Post-hurricane call volume for dead generators is enormous.
Electrical-only dealers subcontract gas work. That means two permits, two schedules, two warranties, and finger-pointing when something fails at the interface.
Air-cooled generators on coastal properties without salt-resistant enclosures and correct placement start showing corrosion at years 3–5. Subtle until it isn't.
Kohler covers parts AND labor for the full 5-year term. Some competitors' warranties shift to parts-only after year 2 — meaning you pay labor when something fails.
A whole-home standby generator is one of the biggest home-services purchases most Florida homeowners ever make — $15,000 to $30,000+, involving electrical work, gas work, permits across two trades, FPL coordination, manufacturer warranties, and ongoing maintenance. It's also one of the most commonly botched.
In Manatee County alone, we see generators every week that were sized wrong, sited in the corrosion zone of a dryer vent, missing maintenance, or quoted by a dealer who didn't hold the gas license to run the line. Getting this purchase right the first time is worth spending an extra hour on the front end.
This is the 15-question checklist from a family-owned generator dealer that's installed 300+ whole-home Kohler systems in Manatee County in the last two years alone — and the only Kohler Titanium AND Bold Certified dealer in the Tampa Bay region.
Before you discuss kW size or price, three things have to be true. If they're not, the rest doesn't matter.
Generator installation requires two Florida licenses: electrical (EC or ER) and gas-plumbing (CFC with gas certification). Dealers who only hold one must coordinate with a second trade — meaning two permits, two schedules, two warranties, and two call-backs if something goes wrong at the interface between the electrical and gas sides.
Ask: Do you pull both permits? Do you do gas work in-house? What's the call-back process if the gas side needs attention two years from now?
Air & Energy: Holds both licenses — EC13011350 (electrical) and CFC1429106 (plumbing and gas) — which is why our generator installs are one crew, one permit window, one warranty.
Generator manufacturers certify dealers in tiers — and the tiers aren't cosmetic. They affect warranty coverage, access to manufacturer training, parts availability, and service response. Kohler's residential dealer tiers: Titanium is the top sales/installation tier. Bold Certified is the top service tier. Both require training, customer-satisfaction benchmarks, and annual renewal.
Generac, Cummins, Briggs & Stratton, and others have parallel tiering. If a dealer can't immediately tell you their tier for the brand they're selling, they're at the entry level.
Air & Energy: The only Kohler dealer in the Tampa Bay region holding both Titanium and Bold.
Generator installs require inspections on both sides. Some dealers skip the gas permit or let the homeowner pull it. Both are red flags.

Six questions that separate a real generator dealer from one who sells by the kilowatt.
Generator sizing is the single most botched part of the install. A 20kW air-cooled unit isn't automatically right for a 2,800 sqft home. It depends on your AC tonnage, electric water heater, well pump, and intended circuit coverage (whole-home vs. essentials-only).
A proper sizing calculation accounts for starting amp draw on your largest motor loads, simultaneous-load scenarios, and fuel-pressure-adjusted output. An undersized generator will either fail to start the AC or will short-cycle and burn out early. An oversized one is expensive and inefficient. Ask to see the sizing calculation on paper.
Air-cooled generators (Kohler 14–26 kW range) are less expensive, simpler, and fine for most single-family homes up to about 3,500 sqft with standard load profiles. Liquid-cooled (24 kW and up) cost more but run quieter, handle higher sustained loads, and last longer under multi-day outage conditions — which matter more on islands and for large homes. The right answer depends on your home, load, and expected runtime during an outage. A dealer who pushes one without asking is selling inventory.
Most Manatee County homes use either natural gas (via utility meter) or propane (via owned or leased tank). Natural gas requires verifying meter size and line pressure — an undersized meter will starve the generator during operation, and utility upgrades take weeks. Propane requires verifying tank size matches expected runtime (a 120-gallon tank runs a 20kW for ~24 hours under moderate load; longer outages need 250-gallon+). Ask the dealer to verify fuel-supply sizing in writing before committing to equipment.
Kohler requires minimum clearances: 18 inches from structures, 60 inches from windows and openings, away from dryer vents, HVAC condensers, and irrigation heads — all of which shorten generator life through corrosion or overheating.
Coastal homes (within 1–2 miles of the Gulf) need aluminum enclosures and specific corrosion-resistant placement. Island installs should default to liquid-cooled with enhanced corrosion packages. A dealer quoting an air-cooled unit on a Gulf-facing Anna Maria home without flagging corrosion risk hasn't worked the islands.
The ATS must match your main panel amperage — 100A, 150A, or 200A. Using an undersized ATS limits generator output. Using the wrong type (service-rated vs. non-service-rated) affects how your meter and mains are configured during an outage. Ask what ATS model they're spec'ing and why.
Many Manatee County communities — particularly Lakewood Ranch, Palma Sola, and various deed-restricted subdivisions — require architectural review for generator placement, screening, or enclosure type. A good dealer knows the HOA landscape and handles the paperwork. A bad one leaves you to figure it out, which can delay the install by weeks or force placement changes after permits are pulled.
For equipment that sits unused for years before running during an outage, the labor coverage and maintenance discipline matter more than the sticker price.
This is where Kohler's residential warranty distinguishes from competitors. Kohler covers all parts and all labor for the full 5-year limited warranty on every covered component. Generac's comparable warranty covers parts and labor in years 1–2, then shifts to parts-only on most components in years 3–5 (engine, rotor, stator are the narrow exceptions) — meaning you pay labor for year 3 onward even when the part is covered.
It's a real difference on a piece of equipment that sees little use until it has to run for 4 days straight. Ask the dealer to walk you through year-by-year warranty coverage, not just “5 years parts and labor.”
Kohler offers an extended 10-year / 2,000-hour warranty for ~$1,095 (air-cooled) or ~$1,395 (liquid-cooled). Generac's extended options vary by generation. Ask specifically what years 6–10 cover, and what the labor situation is during the extension.
Standby generators require annual maintenance — oil changes (hour-based), spark plugs, air filters, battery checks, load testing, remote-monitoring verification. Skipping it can void the warranty and will shorten equipment life. Some dealers sell and never look back. Others enroll you in a structured maintenance program.
Ask what's included in year 1, what annual maintenance costs after that, and whether the same technicians who installed it will be maintaining it.
A generator's real test is hour 14 of an outage with a fault code on the display. Who picks up matters more than any spec sheet.
The real test of a generator dealer is when the power's been out for 14 hours, the generator throws a fault code, and you need someone on-site. Ask specifically: If my generator fails during a named storm, what's the response process? Do you prioritize existing customers? How fast can a technician be on-site? The answer should be specific — not marketing language.
Air & Energy: Prioritizes existing customers during named storms. Response times vary with storm severity and road access — but existing customers get called before new prospects, every time.
Generators are relatively new to many Florida homeowners, but some dealers have been installing them for decades and others started last year. Longevity matters because generator lifespans are 15–20+ years, and you want the dealer still around for year 10 warranty work, year 12 maintenance, and year 17 troubleshooting.
Air & Energy: Installed 300+ whole-home generators across Manatee County in just the last two years, and Kohler standby units for much longer.
Several Sarasota-Bradenton home-services companies have been acquired by PE-backed platforms since 2023. Ask who owns the company.
Air & Energy: Family-owned by the Moon family. No outside capital. Stewart Moon's name is on the truck and his phone rings when something goes wrong. For generators specifically — which need to work on the worst day of the year, require service during named storms, and involve both electrical and gas work that a single crew has to own start-to-finish — a PE-backed regional platform routed through a service queue doesn't deliver the same accountability as an owner whose grandkids still live in the county that just went dark.
A generator that's installed badly, sized wrong, or never maintained will fail at exactly the moment you need it. Most post-hurricane generator failures trace back to install decisions or skipped maintenance.
Natural gas typically keeps flowing during outages (buried utility lines). Propane requires pre-storm topoff and enough tank capacity to run for 4+ days of sustained load. Island homes should plan for extended outage scenarios explicitly.
Kohler OnCue Plus and equivalent systems let you — and your dealer — monitor generator health from your phone. Self-test results, low-oil warnings, fault codes, and run hours all flow to the app. For a $20,000+ piece of equipment, not having this is leaving warranty claims on the table.
Air-cooled generators on coastal properties without salt-resistant enclosures and placement start showing corrosion at years 3–5. It's subtle until it isn't. Coastal homes should specify aluminum enclosures from the start.
