Why Florida Homeowners Need a Standby Generator
Northeast Florida averages more than 100 thunderstorm days per year — and that's before you factor in hurricane season, which runs June through November. Power outages here aren't a matter of if, they're a matter of when.
When the grid goes down in July, temperatures inside an un-air-conditioned Florida home can reach dangerous levels within hours. For families with young children, elderly members, or anyone dependent on powered medical equipment, that's not just uncomfortable — it's a health risk.
The case for a standby generator in Florida:
- Florida ranks #1 in the US for lightning strikes — outages are frequent
- Hurricane season creates multi-day outages across entire counties
- Summer heat makes an AC-less home dangerous within hours
- Sump pumps, medical equipment, and security systems need continuous power
- Standby generators add 3–5% to home resale value
Standby vs. Portable: What's the Difference?
Most homeowners start by comparing standby generators to portable generators. They're very different products designed for different needs.
| Feature | Standby Generator | Portable Generator |
|---|---|---|
| Activation | Automatic (within seconds) | Manual — you must start it |
| Fuel | Natural gas or propane (never runs out) | Gasoline (must stockpile) |
| Power output | 18–150 kW (whole home) | 3–10 kW (select circuits) |
| Installation | Permanent, by licensed electrician | No installation required |
| Indoor use | Safe — installed outside | Never — carbon monoxide risk |
| Cost | $5,000–$15,000+ installed | $500–$3,000 |
| Maintenance | Annual service | After each use |
For most Northeast Florida homeowners, a standby generator is the right choice. The automatic activation alone is worth the investment — you don't have to be home, awake, or physically capable of starting a generator when the power goes out at 2 AM during a hurricane.
How to Size a Generator for Your Home
Generator sizing is the most important decision you'll make. Too small and your HVAC won't run. Too large and you've overspent. The right size depends on your home's square footage, HVAC system size, and which appliances you want to power.
Essential circuits
HVAC (up to 3-ton), refrigerator, lights, outlets, well pump. Best for smaller homes under 1,500 sq ft.
Most of the home
HVAC (up to 4-ton), kitchen appliances, multiple circuits. Ideal for 1,500–2,500 sq ft homes.
Whole home
Full home coverage including large HVAC, EV charger, pool pump, and all appliances. Best for 2,500+ sq ft.
Large home or commercial
Multi-unit, large estate, or commercial applications. Handles multiple HVAC systems simultaneously.
Don't guess on sizing. A licensed technician should perform a load calculation based on your actual electrical panel and HVAC equipment before recommending a generator size. Double A provides this assessment at no charge.
Fuel Types: Natural Gas vs. Propane
Standby generators run on either natural gas (piped from your utility) or liquid propane (stored in a tank on your property). Both are clean-burning and reliable — the right choice depends on your home's existing utilities.
Natural Gas
- Unlimited supply — never runs out
- No on-site storage tank needed
- Lower fuel cost per BTU
- Requires natural gas service at your home
- Not available in all rural areas
Liquid Propane
- Works anywhere — no gas line required
- Higher energy density than natural gas
- Tank size determines runtime
- Requires on-site tank (250–1,000 gal)
- Must schedule propane deliveries
Our recommendation: If you have natural gas service, use it — the unlimited supply is a major advantage during extended outages. If you're in a rural area without gas service, a 500-gallon propane tank will run a 22kW generator for approximately 5–7 days of continuous operation.
Top Generator Brands: Generac, Kohler & More
The standby generator market is dominated by a few major brands. Here's how they compare:
Generac holds roughly 70% of the US residential standby generator market. Their Guardian and PowerPact series offer excellent value, wide dealer support, and a strong parts network. Double A is an authorized Generac dealer and installs Generac systems exclusively for residential customers.
Kohler generators are known for quiet operation and premium build quality. They're a strong choice for homeowners who prioritize noise levels and aesthetics. Slightly higher price point than Generac.
A solid mid-range option with a long history in small engine manufacturing. Good value for budget-conscious buyers, though dealer networks are thinner than Generac.

How Much Does a Whole-Home Generator Cost?
Total installed cost varies based on generator size, fuel type, transfer switch, and site conditions. Here are realistic ranges for Northeast Florida:
| Generator Size | Installed Cost Range | Best For |
|---|---|---|
| 10–14 kW | $5,000 – $7,500 | Smaller homes, essential circuits |
| 16–20 kW | $7,500 – $10,000 | Mid-size homes, most appliances |
| 22–26 kW | $10,000 – $14,000 | Whole-home coverage, larger homes |
| 30–48 kW | $14,000 – $20,000+ | Large homes, commercial |

Maintenance: Keeping Your Generator Ready
A standby generator is only valuable if it starts when you need it. Annual maintenance is essential — and your generator actually helps by running a weekly self-test automatically.
Annual Service
Oil change, spark plugs, air filter, coolant check, battery test, and full system inspection.
Weekly Self-Test
Your generator runs itself for ~12 minutes every week to stay ready. You'll hear it — that's normal.
Load Bank Test
Annual test under full load confirms the generator can handle your home's actual power demand.
Transfer Switch Check
Verify the ATS transfers power correctly and returns to utility power when the grid is restored.
Double A offers annual generator maintenance plans that include all of the above. Learn about our generator maintenance service →
Frequently Asked Questions
How long does installation take?
Most residential installations are completed in one to two days once permits are approved. Permit timelines vary by county — typically 1–3 weeks in Northeast Florida.
Will my generator turn on automatically during an outage?
Yes. A standby generator with an automatic transfer switch (ATS) detects a power failure within seconds and starts the generator automatically — no action required from you.
Can I run my whole house on a 22kW generator?
For most homes under 2,500 sq ft, yes. A 22kW Generac can handle a 4-ton HVAC system, refrigerator, lights, outlets, and most appliances simultaneously. Larger homes or those with multiple HVAC systems may need 26kW or higher.
Does a standby generator add value to my home?
Yes. Studies show whole-home generators add 3–5% to home resale value, and in hurricane-prone markets like Northeast Florida, they're increasingly expected by buyers.
What maintenance does a standby generator need?
Annual service including oil change, spark plug inspection, air filter replacement, battery check, and load bank test. Your generator also runs a weekly self-test automatically to stay ready.
Is a permit required for generator installation in Florida?
Yes. Florida requires an electrical permit for standby generator installation. Double A handles all permitting and inspections on your behalf.
