Standby Generator Shopping Guide for The Gulf Coast Homeowners & Coastal Businesses

Power outages across the Gulf Coast. are common, especially during hurricane season and extreme heat events. Losing electricity can shut down air conditioning, refrigeration, medical equipment, security systems, and business operations in minutes.

A standby generator delivers automatic, whole-home power when utility service fails, keeping your air conditioning, refrigeration, lighting, security systems, and medical devices running without interruption.

This standby generator shopping guide is built to help Gulf Coast residents make a smart, safe, and long-term backup power decision. You’ll learn how to choose the right generator size, fuel type, brand, and installer without confusion or overspending.

Why Standby Generators Are a Smart Choice in the Gulf Coast

Homes across the Gulf Coast face repeated power risks from hurricanes, tropical storms, heat-driven grid overloads, and aging infrastructure. A standby generator is a permanent, automatic power system that restores electricity within seconds of an outage. Unlike portable units, it connects directly to your home’s electrical panel and fuel supply

Unlike portable generators, standby systems connect directly to your electrical panel and fuel supply, activating within seconds of a utility outage. For homeowners from the Gulf Coast this automated system provides a level of security that portable motors simply cannot match.

Starts Automatically

You don’t need to go outside in a storm to pull a cord.

Runs on Natural Gas or Propane

No need to store messy, dangerous gasoline cans or refuel every few hours.

Powers Your Whole Home

You can choose to power just the essentials (like the A/C and fridge) or your entire home.

Operates Safely

It’s installed outside, away from windows, reducing risks from noise and carbon monoxide.

How to Choose the Right Generator Size for Your Property

Selecting the correct generator size is the foundation of a successful installation. Sizing your system correctly ensures you don’t overspend on power you won’t use or end up with a unit that stalls when the AC kicks in. Too small, and critical systems won’t start. Too large, and you pay more than necessary. 

Professional installers perform a load calculation, but these steps explain the process.

Step 1: List Your Essential Loads

Think about what you truly need during a multi-day outage. Most families prioritize:

Common Essentials

  • Central Air Conditioning (Critical for the Gulf Coast)
  • Refrigerator and freezer
  • Interior lighting
  • Internet and communication devices
  • Medical equipment
  • Garage door and security systems

 

Whole-home coverage may also include:

  • All lighting and outlets
  • Cooking appliances
  • Laundry equipment
  • Well pumps or sump pumps
  • Pool systems
  • EV charging (where applicable)

Step 2: Estimate Power Demand

Appliances with motors, like your refrigerator or AC, need a “surge” of power to start up. This is often double or triple the power they need to keep running. Our professional generator experts always recommend a load calculation by a certified technician to ensure your unit handles these peaks safely.

Every appliance uses two types of power:

  1. Running Watts: The steady power it needs to run.
  2. Starting (Surge) Watts: The extra burst of power it needs just to turn on. An A/C unit or refrigerator needs a big “kick” to start its motor.

Every appliance draws:

  • Running watts (continuous power)
  • Starting watts (initial surge)

Most Florida homes fall within:

  • 14–18 kW for essentials
  • 20–26 kW for whole-home comfort
  • 30+ kW for large or commercial properties

A certified installer confirms exact sizing before installation

Appliance

Running Watts

Starting Watts

Central A/C (5 ton)

3,500 – 5,000

6,000 – 8,000

Refrigerator

700

1,200

Lighting & Outlets

1,000 – 2,000

Well Pump

1,000

2,000

Step 3: Choose Your Fuel Source

Fuel choice impacts performance and long-term convenience.

  • Natural Gas: Continuous supply, minimal maintenance
  • Propane: Ideal for rural or coastal locations without gas lines
  • Diesel: Typically reserved for commercial or industrial use

Pro Tip: Natural Gas: Best for urban areas like Mobile, AL, where lines are already buried. Liquid Propane (LP): Ideal for rural parts of the Gulf Coast. It is stored in large on-site tanks and has a long shelf life.

Step 4: Install an Automatic Transfer Switch (ATS)

The transfer switch safely disconnects your home from the grid and powers it from the generator automatically. Advanced systems manage loads to protect appliances and maximize efficiency.

Before You Buy

  • Confirm fuel availability
  • Match generator capacity to HVAC size
  • Plan generator placement and clearances
  • Verify permit requirements

Permits, Codes, and Professional Installation in Florida & Alabama

Installing a standby generator involves electrical, gas, and structural compliance. Florida building codes are strict, especially in coastal and hurricane-prone zones.

Why Professional Setup is Required?

A certified installation involves more than just placing the unit. It requires a reinforced concrete pad to withstand high winds and proper elevation to avoid localized flooding. Furthermore, your installer must pull specific permits:

  1. Electrical Permits: To safely wire the Automatic Transfer Switch (ATS) into your main panel.

  2. Plumbing/Gas Permits: To ensure the fuel lines are leak-proof and meet pressure standards.

  3. Mechanical Permits: For the physical placement of the unit relative to windows and doors.

By choosing a local expert, you ensure your system is legal and won’t complicate a future home sale. Our team handles every step of the permitting process for our clients in the Gulf Coast, and surrounding areas.

Common Permit Requirements

  • Electrical permit for panel and transfer switch
  • Gas or propane permit for fuel connections
  • Building permit for generator placement

Clearance rules address distance from windows, doors, property lines, and airflow paths.

Licensed installers manage:

  • Permit submissions
  • Utility coordination
  • Final inspections
  • System commissioning

Local requirements vary across the Gulf Coast.

Best Installation Practices

In places like the Gulf Coast, there are strict rules. You must have a permit. This makes sure the unit is safe for you and your neighbors. Our team handles all the paperwork. We work with the city and the county so you don’t have to.

The Concrete Pad

A generator must sit on a strong base. Near the coast, we have to worry about flooding and soft sand. We use reinforced concrete pads. This keeps the unit level and dry. We also make sure the unit is the right distance from your windows. This keeps you safe from exhaust fumes.

Salt and Air

The Gulf Coast has salty air. This can make metal rust very fast. We help you choose units with special coatings. Brands like Kohler and Tradewinds make units that fight rust. This is a key part of our generator buying guide for coastal homes. We want your machine to last for twenty years, not five.

Safety Inspections

Once we finish the work, a local inspector looks at it. They check the gas lines and the wiring. This is for your protection. We stay on-site to make sure everything passes. We want you to know that your home is safe and follows all the laws. Choosing a local expert means you are getting a team that lives and works in your area

Unpermitted installations can void warranties, create safety risks, and delay property sales.
