Generator Installation
Louisville, KY
Louisville weather doesn’t always play nice. From heavy thunderstorms to sweltering summer heat, the power grid can struggle. In some neighborhoods, losing electricity isn’t rare; it’s expected a few times a year. When the lights go out, keeping your home comfortable, your food safe, and your family secure becomes a challenge quickly.
A home generator eliminates that worry.
With a properly installed backup system, your power remains steady during outages, giving you heating, cooling, lighting, refrigeration, and the ability to keep life moving as normal.
St. Matthews Electric proudly serves Louisville and surrounding communities with professional generator installation designed for safety, efficiency, and total home protection.
If you’re considering backup power, our team can guide you through every step.

Why Homeowners Install Generators
Continuous power during storms and blackouts
A standby generator ensures your home remains fully powered when storms or grid outages strike. Instead of scrambling for flashlights, lights, appliances, and essential electronics continue running.
Protection for refrigerators, freezers, and medical devices
With a generator, critical appliances continue operating, preventing loss of perishable goods and maintaining proper conditions for medications or medical equipment. In Louisville’s humid summer months or icy winter periods, keeping refrigerators and freezers running helps avoid both financial loss and home health hazards.
Maintains HVAC and home comfort systems
Generators allow your heating and cooling systems to operate during outages, protecting your home from extreme temperatures. This benefit is particularly important in Louisville, where summer storms and winter freezes can affect homes unexpectedly.
Boosts home value and peace of mind
Buyers increasingly seek properties with backup power solutions, recognizing the security and convenience generators provide. Beyond resale value, a generator gives homeowners peace of mind, knowing their family, property, and electronics are protected year-round, no matter the weather or unexpected grid failures.
What to Consider Before Installing a Generator
Before installation begins, homeowners should take some time to plan. A generator isn’t a one-size-fits-all investment, it needs to match your home and your lifestyle.
Generator Size & Power Capacity
Do you want to power the whole house or only essentials like the refrigerator, lights, and HVAC? Whole-home generators require more capacity, while smaller standby units can support critical items only.
Because every home is different, a load assessment performed by St. Matthews Electric can help determine an ideal capacity without overspending or under-powering your system.
Fuel Source
Most residential standby generators run on either natural gas or propane. Natural gas provides a continuous supply without the need for tank refills, making it convenient and cost-efficient for homes already connected to a gas line. Propane burns cleanly and stores well long-term, making it practical for locations where natural gas access is limited.
Choosing the right fuel source depends on what’s available at your property, how you plan to maintain fuel supply, and your long-term operating preferences.
Placement & Safety
Generators must sit a safe distance from windows and doors to prevent carbon monoxide buildup, and they require a stable surface. Louisville building codes also include spacing requirements that determine how close a generator can sit to property lines or structures.
As a licensed installer, we will evaluate your yard, exterior layout, and access points to determine the best placement while ensuring code compliance and safe operation.
Transfer Switch Options
Another decision homeowners must make involves the transfer switch, which controls how the generator connects to the home’s electrical panel. An automatic transfer switch turns the generator on the moment power fails. A manual switch works too, but requires homeowner action.
Generator Installation Process
Installing a generator involves more than simply placing a unit outside and plugging it in. A safe installation requires proper electrical connection, correct sizing, and compliance with building codes.
Here’s what homeowners can expect:
Initial Site Inspection
We review your power needs and determine the right generator size. This step also includes fuel source planning and discussions about whether an automatic or manual transfer switch is best for your setup.
Generator Selection & Placement
We help you select the right Generac generator model for your home and prepare a safe, code-compliant installation site — typically on a concrete pad or gravel base with proper clearance and ventilation.
Transfer Switch Installation
We respect your time as much as your home. That’s why we offer a tight 30-minute arrival window and send text notifications when your technician is on their way.
System Testing & Walkthrough
After setup, the system is tested to verify that the generator activates correctly, delivers consistent output, and transitions smoothly during a simulated outage. Then we explain how the generator functions, what to expect during an outage, and how to perform basic maintenance.
