Generac Generator Installation & Service in Joshua, TX

A Generac standby generator sits outside your home or business and waits. When utility power drops, an automatic transfer switch senses it, starts the generator, and switches your building over to generator power — typically within seconds, and without you touching a thing. When the utility comes back, the switch returns you to grid power and the generator shuts itself down. It runs on your existing natural gas or propane supply, so there are no gas cans to fill and no extension cords to string through the house.

As a Generac Dealer (#1030576), Inland-Marine Electrical Services handles the full job: helping you size the unit to what you actually want to keep running, setting the automatic transfer switch, making the electrical and fuel connections, and performing the maintenance and service that keep the unit ready. We install for both homes and businesses across our North Texas service area — anywhere a power outage means spoiled food, a cold (or sweltering) house, a stopped-up well pump, or a business that can't afford to go dark.

Standby vs. portable. A portable generator has to be rolled out, fueled, started by hand, and connected with cords — and you have to be home to do it. A standby generator is permanently installed, starts itself, and powers your existing electrical panel through an automatic transfer switch. The difference matters most in the middle of the night, or when you're away from home, or when the outage lasts for days instead of hours.

Reasons North Texas homeowners and businesses call us about a standby generator:

• You've lived through an outage that lasted more than a few hours and don't want to do it again.
• You rely on a well pump, sump pump, medical equipment, or refrigeration that can't go down.
• You run a business — a shop, office, or outbuilding — where even a short outage costs you money or shuts down work.
• You have a Generac unit already and it's due for service, won't start on its weekly test, or threw an error code.
• You're planning a new build or a service upgrade and want the generator rough-in done at the same time.

North Texas outage risk is real and worth saying plainly. Severe storms and high winds take down lines across Johnson and Tarrant counties every season, and the February 2021 winter storm left many homes without power for days in the cold. A standby generator won't prevent an outage — but it turns a multi-day emergency into a non-event.

Here's how Jim handles a Generac installation from first call to final walkthrough:

1. Conversation and load walk-through. We talk through what you want to keep running during an outage — the essentials only, or the whole house. That list drives the sizing.
2. Sizing and selection. Sizing depends on what you want to run. A unit sized for a furnace, fridge, well pump, and a few lights is different from one sized to carry two air conditioners and a shop. We help you land on the right size — not the biggest unit, the right one.
3. Placement and permitting. We pick a location that meets clearances and code, pull the permit, and coordinate the fuel connection with your gas or propane provider.
4. Automatic transfer switch and electrical connection. The transfer switch is the heart of the system. It's what safely disconnects your home from the utility before the generator powers it — and that matters for a specific, important reason.
5. Start-up, load test, and walkthrough. We start the unit, test it under load, walk you through the controls and the weekly self-test, and hand over the paperwork.

Why a transfer switch matters — never back-feed a home. Connecting a generator to your panel by plugging it into a dryer outlet or any household receptacle is called back-feeding, and it is dangerous. Without a proper transfer switch, generator power can flow backward out of your panel, onto the utility lines, and energize the very lines a utility worker believes are dead. That can injure or kill a line worker working to restore your power. A transfer switch eliminates that hazard by physically breaking the utility connection before the generator connects. It is not optional — it is the safe, code-compliant way to do the job, and it is the only way we do it.

We never quote a price without seeing the job — every home and every panel is different. What follows is an honest explanation of what drives the cost, not a price list. Jim will give you a clear, written quote before any work starts.

• Unit size (kW). A bigger unit that runs more of the house costs more than a smaller essential-circuits unit.
• Fuel type and run length. Natural gas and propane connections differ in what's required to tie in, and the distance from the fuel source to the generator affects the fuel-line work.
• Placement and site work. A pad, gravel base, or concrete pad; clearances from windows, doors, and gas meters; and the trenching distance to the panel all affect the install.
• Electrical work. The distance from the generator to your panel, whether a sub-panel or load-shedding setup is needed, and whether your service needs upgrading to accept the generator.
• Permitting and inspection. Permit fees and the required inspection vary by city.

Financing is available on qualifying work. Call Jim and he'll walk you through both the quote and the financing options.
