Choosing the Right Generator for Your Florida Home
Extended power outages are one of the most disruptive consequences of hurricanes in Southwest Florida. After Hurricane Ian in 2022, more than 2.6 million Florida customers lost power, and some areas of Lee and Charlotte counties were without electricity for two to four weeks. Hurricane Milton in 2024 caused similar widespread outages across Sarasota, Manatee, and Hillsborough counties.
In Florida, losing power means losing air conditioning : and in our subtropical climate, that creates dangerous heat conditions, accelerates mold growth in storm-damaged homes, and makes recovery work extremely difficult. Choosing the right generator for your home is not a luxury. It is an essential part of hurricane preparedness.
Understanding Generator Sizing: Watts Explained
Generators are rated in watts (W) or kilowatts (kW). Every appliance in your home requires a specific number of watts to run, and most have two ratings:
- Running watts: The continuous power needed to keep the appliance operating
- Starting watts (surge watts): The extra burst of power needed when the appliance first turns on, typically 2-3 times the running watts for motor-driven appliances
Your generator must be large enough to handle both the combined running watts of everything you want to power simultaneously AND the starting watts of the largest motor in the group.
Common Appliance Wattage Requirements
| Appliance | Running Watts | Starting Watts |
|---|---|---|
| Central AC (3-ton, common in FL) | 3,500 | 7,000 |
| Central AC (4-ton) | 4,500 | 9,000 |
| Central AC (5-ton) | 5,500 | 11,000 |
| Window AC unit (10,000 BTU) | 1,200 | 1,800 |
| Refrigerator | 150 | 400 |
| Freezer (upright/chest) | 100 | 300 |
| Well pump (1/2 HP) | 1,000 | 2,100 |
| Sump pump (1/3 HP) | 800 | 1,300 |
| Electric water heater | 4,500 | 4,500 |
| Microwave (1,000W) | 1,000 | 1,000 |
| Lights (10 LED bulbs) | 100 | 100 |
| Phone/device chargers | 50 | 50 |
| TV and internet router | 250 | 250 |
| Medical equipment (CPAP) | 150 | 150 |
| Medical equipment (oxygen concentrator) | 300 | 600 |
Sizing Scenarios for SW Florida Homes
Scenario 1: Basic Essentials (3,500-5,000 watts)
Covers refrigerator, freezer, lights, fans, phone chargers, and a window AC unit for one room.
- Generator type: Portable (inverter or conventional)
- Cost: $800 – $2,500
- Best for: Apartments, condos, or budget-conscious homeowners willing to sacrifice central AC
Scenario 2: Comfortable Living Without Central AC (7,500-10,000 watts)
Covers refrigerator, freezer, lights, fans, phone chargers, TV, microwave, well pump, and 2-3 window AC units.
- Generator type: Large portable or small standby
- Cost: $2,000 – $5,000 (portable) or $4,000 – $7,000 (installed standby)
- Best for: Mid-size homes where central AC is not a priority
Scenario 3: Whole-House With Central AC (14,000-22,000 watts / 14-22 kW)
Covers everything in your home including central air conditioning. This is the most practical option for Florida homeowners who need to remain in their home during extended outages.
- Generator type: Whole-house standby (permanently installed)
- Cost: $5,000 – $15,000 installed (natural gas or propane) or $8,000 – $20,000 (diesel)
- Best for: Homeowners who want seamless, automatic power restoration and need central AC for health, comfort, or to prevent mold growth in a storm-damaged home
Portable vs Standby Generators: Comparison
| Feature | Portable Generator | Standby Generator |
|---|---|---|
| Startup | Manual pull-start or electric start | Automatic : turns on within seconds of power loss |
| Fuel | Gasoline (some dual-fuel with propane) | Natural gas, propane, or diesel |
| Fuel availability after hurricane | Gasoline shortages are common | Natural gas lines usually remain active; propane can be pre-filled |
| Run time | 8-12 hours per tank (gasoline) | Unlimited (natural gas) or days/weeks (propane tank) |
| Power output | 3,000-12,000 watts typical | 10,000-48,000 watts (10-48 kW) |
| Noise level | 60-80 dB (inverters quieter at 55-65 dB) | 60-70 dB (comparable to a conversation) |
| Installation | None required | Professional installation with transfer switch: $2,000-$5,000 |
| Maintenance | Owner-maintained | Annual service recommended ($200-$400) |
| Home value impact | None | Adds $3,000-$5,000 to home resale value |
Critical Safety Rules for Generator Operation
Generator misuse kills people every hurricane season. Carbon monoxide (CO) poisoning from improperly placed generators is one of the leading causes of death after hurricanes in Florida.
Non-Negotiable Safety Rules
- NEVER run a generator inside your home, garage, lanai, or any enclosed or partially enclosed space. Carbon monoxide is odorless and deadly. Place the generator at least 20 feet from any window, door, or vent opening.
- NEVER plug a generator directly into a wall outlet (backfeeding). This sends power back through your electrical panel to the utility lines, endangering line workers and neighbors. Use a properly installed transfer switch or plug appliances directly into the generator.
- Let the generator cool before refueling. Gasoline on a hot engine causes fires.
- Use heavy-duty outdoor-rated extension cords sized for the load. Undersized cords overheat and create fire hazards.
- Install carbon monoxide detectors inside your home on every floor. Battery-operated models work when the power is out.
When Power Outages Lead to Further Damage
Extended power outages in Florida create secondary damage that many homeowners do not anticipate. Without air conditioning, indoor humidity rises above 70% within hours, creating ideal conditions for mold growth : especially in homes that have already sustained water intrusion from the storm. Without a sump pump, flooding worsens. Without power to run dehumidifiers, structural drying cannot begin.
If your home has sustained storm damage and you are without power, professional restoration becomes even more urgent. WrightWay Emergency Services arrives with our own generator-powered equipment : commercial extractors, dehumidifiers, air movers, and air scrubbers : so your home’s drying and restoration begins immediately regardless of the grid status.
Plan Your Power Backup Now
Generator demand spikes every hurricane season, and after a major storm, portable generators sell out within hours and standby generator installers are booked months in advance. The time to purchase and install your generator is now : before the June 1 start of hurricane season.
