Every hurricane season, Polk County homeowners rediscover the same truth: the grid is the last thing to come back. The generator decision is really three decisions — how much of your home you want powered, how automatic you want it to be, and what you're willing to do during an outage versus before one.
Here's the framework, including the honest cases where a portable unit is the right answer.
The three tiers of backup power
A portable generator (gas, typically 3,500–12,000 watts) is the entry tier: it powers selected loads through extension cords, or — much better — through a manual transfer switch and inlet box an electrician installs. You fuel it, start it, and rotate loads yourself. Its fatal misuse is backfeeding: plugging it into a dryer outlet, which can kill a utility line worker and is illegal everywhere.
An automatic standby generator (like the Generac units we install) is permanently mounted, runs on propane or natural gas, and starts itself within seconds of an outage via an automatic transfer switch (ATS). Sized right, it carries the whole home — AC included — for as long as fuel holds. It also exercises itself weekly and doesn't care whether you're home.
The middle path many homes miss: a properly installed manual transfer switch with a quality portable unit. For a fraction of standby cost, you get safe, code-compliant backup of your chosen circuits — fridge, well pump, some lights, a window AC — with the trade-off being your labor during the outage.
How to choose your tier
- 01 List your non-negotiable loads first: medical equipment, well pump, fridge/freezer, and (the Florida question) air conditioning. AC is what pushes homes from portable to standby.
- 02 If anyone in the home can't tolerate heat, or you travel often, or outages must be invisible → standby is the answer; everything else is compromise.
- 03 If you can cheerfully run cords and rotate loads for a few days → a portable + manual transfer switch is honest value.
- 04 Fuel reality check: gasoline requires storage and staleness management; propane stores indefinitely; natural gas (where available) never runs out. Fuel logistics fail more outages than hardware does.
- 05 Whatever the tier, the transfer switch is the safety heart of the system — it's what makes backup power and utility power physically unable to meet.
Where generator plans fail
- Backfeeding through a dryer or range outlet — the most dangerous shortcut in residential power, full stop.
- Buying the generator but skipping the transfer switch 'for now,' then improvising during the first real outage.
- Undersized standby units that trip on AC start-up current because sizing ignored motor inrush.
- Portables run too close to the house — carbon monoxide kills more people after hurricanes than the storms' electrical hazards do; 20 feet from openings, minimum.
- Standby units that were never maintained: a generator that hasn't exercised, or sits with stale fuel lines, is lawn sculpture when the storm arrives.
Why trust this guidance?
- Top Flight Electric is a Generac partner installing standby systems and transfer switches across Polk County — sizing against real AC inrush loads is standard practice on every quote.
- Reviewed under Florida electrical-contractor license EC13005699; installs are permitted and inspected, with flat-rate written pricing before work begins.
- Family-owned and local since 2017 — our own homes ride out the same storm seasons this guide is written for.
What should you do next?
Decide your tier before the season's first named storm, not during it — install lead times stretch when everyone decides at once. A free consultation sizes the system against your actual loads and fuel options.
Frequently Asked Questions
How big a standby generator does a typical home need? +
It depends almost entirely on air conditioning tonnage and whether you want whole-home or essential-circuits coverage. Whole-home for a typical Central Florida single-family house often lands in the 18–26kW range, but the load calculation — including AC start-up current — is what decides it, not square footage alone.
Can I add a transfer switch to a portable generator I already own? +
Yes — a manual transfer switch and exterior inlet box is a straightforward licensed install, and it converts a cord-spaghetti setup into safe, code-compliant selected-circuit backup. It's one of the best-value storm upgrades available.
How often should a standby generator be serviced? +
Annual service plus the unit's automatic weekly self-exercise is the baseline. Before hurricane season, verify the exercise log, battery, and fuel supply — a generator's failure mode is silence, and you want to find it in May, not September.
