Whole-Home Generator Installation in Perryville & Nearby
A whole-home generator provides reliable, automatic backup power, ensuring your family and property are protected during an outage. We handle the entire installation process to ensure your system is perfectly matched to your needs. Our service begins with a thorough load calculation to determine the right size generator for your home. We then handle the site preparation, including setting the concrete pad and positioning the generator. We install a professional automatic transfer switch, which senses an outage and turns on the generator automatically, eliminating the need for you to do anything.
We work with top brands like Generac and Briggs & Stratton to provide durable and high-performing systems.

Choosing the Right System
Choosing the right generator for your home is a key step. Here’s a quick guide to help you understand your options.
Standby vs. Portable + Interlock
A standby generator is a permanent, automatic solution that provides power to your entire home or a selected set of circuits without any manual effort. A portable generator requires you to manually start it and run extension cords. To use a portable generator with your home's circuits, you need a manual transfer switch or interlock kit, which we can install. Standby generators are the safest and most convenient option.
Transfer Switches
The transfer switch is the brain of your generator system. An automatic transfer switch detects an outage and powers your home from the generator. A manual transfer switch requires you to flip a switch to activate the generator. We can install a transfer switch for your entire home or for a specific list of essential circuits, based on your needs and budget.
Fuel Sources
Generators can run on natural gas or propane. A natural gas generator is connected to your home's existing line, providing an endless supply of fuel. A propane generator uses a large tank, which requires periodic refilling. We'll help you decide on the best fuel source for your property and coordinate with the necessary utility or propane supplier.
Noise & Placement
Generators require careful placement to ensure proper airflow and to meet local zoning laws and noise ordinances. Our team will help you find the best location for your generator, ensuring it's a safe distance from windows and doors and meets all manufacturer and code requirements.

Generator Installation FAQ

Do I need a transfer switch?
Yes. A transfer switch is required for all standby generator installations. It safely isolates your home from the main power grid, which is a code-compliant way to operate.
How long does installation take?
The physical installation of the generator typically takes 1–2 days. This is after all permits and fuel line connections have been approved and completed, which can vary in time. We'll give you a clear timeline from your initial quote to final installation.
What size generator do I need?
We size generators based on your home's specific electrical load and your priorities. We can install a system to power your entire home or just your essential circuits. Our on-site assessment will help us determine the best fit for your needs.
Do you handle permits and fuel?
Yes. We handle all the permitting paperwork and inspections for your generator installation. We also coordinate with your natural gas utility or a local propane supplier to ensure the fuel source is properly set up.
