Whole House Generator Installation in Charleston, SC
When severe weather strikes Charleston, the question isn't if the power will go out, but for how long. Hurricane season, intense thunderstorms, and an aging electrical grid can leave your family in the dark, without air conditioning, refrigeration, or modern conveniences. A whole house generator is the definitive solution, providing automatic, uninterrupted power to keep your home safe, comfortable, and fully operational, no matter the conditions outside.
Unlike portable generators that require manual setup and can only power a few items, a whole house generator is a permanent, powerful solution. It integrates directly with your home’s electrical system, standing ready 24/7. The moment an outage is detected, your generator automatically starts and restores full power to your home in seconds, ensuring life continues without disruption.

Why a Whole House Generator is a Necessity in the Lowcountry
For Charleston homeowners, a standby generator is more than a luxury—it's a critical component of home preparedness. Power outages in our hot, humid climate can quickly escalate from an inconvenience to a serious problem.
- Uninterrupted Comfort: Keep your central air conditioning running during sweltering summer outages. Maintain heat during rare winter cold snaps and ensure you always have hot water.
- Essential Safety and Security: Power medical equipment, keep security systems active, and maintain communication with the outside world. Well pumps, sump pumps, and garage doors will continue to operate, protecting your property.
- Protect Your Property and Valuables: An extended outage can lead to thousands of dollars in spoiled food. More importantly, maintaining climate control prevents the risk of mold growth and damage to sensitive electronics, hardwood floors, and furniture.
- Seamless Operation with an Automatic Transfer Switch (ATS): The core of a whole house generator system is the Automatic Transfer Switch. This intelligent device constantly monitors the electrical feed from the utility company. The instant it senses a disruption, it safely disconnects your home from the grid and simultaneously signals the generator to start, transferring power seamlessly. When utility power is restored, the ATS reverses the process automatically. This hands-free operation means you don’t have to do a thing—power is restored whether you are home or away.

Choosing the Right Size Generator for Your Home
Determining the perfect generator size depends on your specific needs. Do you want to power just the essentials, or your entire home?
- Essential Circuit Coverage (10-14 kW): These smaller, air-cooled units are an excellent choice for powering critical systems. This typically includes your refrigerator, freezer, lights in key areas, a small air conditioning unit or furnace, and essential outlets for charging devices.
- Managed Whole-House Coverage (18-22 kW): The most popular choice for Charleston homes, this range provides enough power for most, if not all, of your home’s circuits. These generators can typically run a central air conditioner, all kitchen appliances, lighting, and entertainment systems simultaneously.
- Complete Whole-House Power (24-48 kW+): For larger homes or those with multiple high-demand appliances like two central AC units, pool pumps, or electric vehicle chargers, a liquid-cooled generator provides robust, unwavering power to run everything without compromise.
Our experts will help you analyze your energy usage to find the perfect balance of performance and value for your home.

Frequently Asked Questions About Whole House Generators
How much does a whole house generator installation cost?
The total investment depends on several factors, including the size of the generator, the complexity of the electrical and gas line installation, and local permitting fees. We provide detailed, transparent quotes after our initial on-site consultation.
How long does the installation take?
A standard installation is typically completed within one to two days. The entire process, from consultation to final inspection, may take a few weeks depending on permit approval times in the Charleston area.
What fuel do whole house generators use?
Most residential generators run on natural gas or liquid propane (LP). Natural gas is a convenient and endless fuel source if available at your property. Propane is stored in a dedicated tank on-site and is a reliable option for homes without natural gas access.
How often does my generator need maintenance?
To ensure reliability and longevity, generators require routine maintenance, much like a car. We recommend professional service at least once a year, or after every 200 hours of operation, to perform tasks like oil and filter changes, battery checks, and system diagnostics.
