Whole-Home Generator Installation & Service in Huntsville, AL
Power outages across North Alabama happen without warning — and they don't wait for a convenient time. Durham Service Company installs Generac whole-home generators and services all makes and models so your family stays safe, comfortable and in control when the grid goes down. When you think dependable, think Durham.
Keep Your Home Comfortable Year-Round
Power Outages in North Alabama Are a Real Risk
North Alabama sits in a region prone to severe thunderstorms, ice storms and tornado activity. When a storm knocks out power in Madison County, outages routinely last hours — sometimes days. Without a backup power source, your home loses heating or cooling, refrigerated food, medical equipment, lighting and security systems.
A whole-home standby generator changes that. It runs on natural gas or propane, starts automatically within seconds of an outage and powers your entire home without any action on your part. You don't flip a switch. You don't drag anything out of a garage. It just works.
We Install Generac — The Most Trusted Name in Home Generators
When it comes to new whole-home generator installations, Durham Service Company installs Generac. Generac invented the home standby generator category and remains the number one selling brand in the United States. Their systems are built for automatic operation, long-term reliability and North Alabama's demanding climate conditions.
Why Generac stands out:
Automatic transfer switch activates within seconds of an outage
Runs on natural gas or LP — no refueling required
Powers your entire home, not just select circuits
Built-in self-testing keeps the system ready at all times
Strong manufacturer warranty backed by an authorized local dealer
As an authorized Generac dealer, we size and install the right system for your home's specific power needs. You get proper load calculations, professional installation and a system that performs when it matters.
We Also Service All Generator Makes and Models
Already have a generator from another brand? We service it. Our technicians work on all major whole-home generator brands and handle repairs, diagnostics and tune-ups regardless of who installed the system.
Generator service we provide:
Full system diagnostics and troubleshooting
Transfer switch inspection and repair
Battery and starter service
Fuel system inspection
Electrical connection checks
General repairs across all major brands
If your generator failed during a recent outage or hasn't been serviced in a while, call us. A generator that isn't maintained is a generator you can't count on.
How a Whole-Home Generator Installation Works
1. Free In-Home Assessment
We visit your home, assess your power needs and calculate the right generator size for your square footage, appliances and priorities. You get a clear, honest recommendation — not a one-size-fits-all pitch.
2. Equipment Selection
We recommend the right Generac system for your home and walk you through what it covers, how it operates and what to expect from the installation process.
3. Professional Installation
Our licensed electricians and technicians handle the full installation — generator placement, transfer switch wiring, fuel line connection and system testing. Every installation meets Alabama code requirements.
4. System Walkthrough
Before we leave, we walk you through how the system operates, what to expect during an outage and how to read your system's status panel. You leave the process confident, not confused.
