Generator Sizing Guide for Florida Homes During Power Outages

May 6, 2026 4 min read Storm Damage

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

  1. 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.
  2. 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.
  3. Let the generator cool before refueling. Gasoline on a hot engine causes fires.
  4. Use heavy-duty outdoor-rated extension cords sized for the load. Undersized cords overheat and create fire hazards.
  5. 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.

Great company with exceptional attention to detail. The people are all friendly and willing to help with whatever needs you may have. Highly recommend!
★★★★★
I have had to work with WrightWay over the last couple of years for repairs to our roof. They have been amazing, acknowledging and coming by to check and repair our home. The initial inspections by Joe were very thorough and then all the follow up and drywall repairs done by Clarence and Ken were great! Our place was left tidy and the work done was great! Very happy with their service!
★★★★★
We were referred to WrightWay from our Condo representative. They were quick to the property to give us an estimate and started right away. Their work was well done, they were easy to communicate with, and sent pictures which were important due to the fact that we reside in Illinois. After talking to Clarence and Logan we were very comfortable giving them access to our property. They even made it look better!
