When the grid drops in the middle of a storm, a standby generator is the difference between an inconvenience and a house with no water, no refrigeration, and no air conditioning. Corbin’s Air, Water & Power Solutions, Inc has served Guntersville, AL since 1935, and we handle whole-house generator installation as well as standby generator repair across Marshall County, the Lake Guntersville shoreline, and homes throughout the Tennessee Valley. We are family-owned, answer the phone with a live person at any hour, provide free estimates, and offer GoodLeap financing on backup power projects.

Backup power ties directly into your service panel and grounding system, and the broader scope of that work is described on the Electrical page.

Storm Season Outages in North Alabama and What a Standby Generator Covers

North Alabama sits in one of the more active severe weather corridors in the country. Spring line storms, summer thunderstorms, winter ice, and the occasional tornado warning all put the same pressure on the distribution system, and rural feeders are typically the last ones restored.

A home backup generator keeps running:

Refrigeration, freezers, and the food stored in them
Heating and cooling so the house stays livable through a multi-day outage
Well pumps, septic pumps, and sump pumps
Medical equipment, internet, and phone charging
Lighting, garage doors, and security systems

Why well water homes lose water pressure the moment power drops

Properties on well water have no reserve once the pump stops. Toilets stop refilling, showers stop, and the pressure tank empties within minutes. That is why so many of the whole-house generator installation calls we take in Marshall County come from homeowners outside the city water system who lived through one long outage and decided not to repeat it.

Sizing a Generator for Your Home, Well Pump and HVAC Load

Sizing is where most generator projects succeed or fail. A unit that is too small trips on motor startup. A unit that is far larger than needed costs more to buy, install, and fuel. Generator sizing starts with a real load calculation, not a square footage guess.

We measure and discuss:

Whole-house versus partial load and managed load options
Starting current for air conditioning compressors, well pumps, and shop equipment
Natural gas versus propane fuel selection based on what is available at the property
Circuit priorities if you would rather cover essentials than the entire panel
Panel condition, because an aging panel may need attention before a generator is added

Load management devices have changed the math in the last several years. Instead of buying capacity for the worst-case moment when the air conditioner, well pump, and range all start together, a managed load setup sheds the lower-priority circuit for a few seconds. That often lets a smaller, less expensive unit cover a full house comfortably. We size and install Generac’s full residential lineup, including their load management devices, so the equipment recommendation is backed by both a proper load calculation and our factory training on that specific product line.

Installation Day: Pad, Gas Line, Transfer Switch and Startup

A standby installation is three trades in one day: electrical, gas, and equipment setup. Corbin’s holds the licenses for all of it, which is why our customers deal with one company rather than coordinating a plumber, an electrician, and a startup technician. As a certified Generac dealer, we install according to factory specifications, which keeps the manufacturer’s warranty intact from day one.

The installation includes:

Setting the pad, with permits, clearances, and placement rules observed for windows, vents, and property lines

Running and pressure testing the gas or propane supply line to the unit

Automatic transfer switch installation and load-side wiring at the panel

Grounding, bonding, and surge considerations for the new equipment

Commissioning, startup, and a walkthrough of the controls with you

Automatic transfer switch operation explained

The transfer switch watches utility voltage. When it disappears, the switch signals the generator to start, waits for stable output, then isolates the house from the grid and connects it to the generator. When utility power returns and holds, the process reverses, and the unit cools down before shutting off. That isolation is also what protects line crews, which is why portable generator dangers matter so much: backfeeding through a dryer outlet endangers everyone working the line, and a proper interlock or transfer switch is the only safe alternative.

Annual Maintenance That Keeps a Standby Unit Ready to Run

A generator is an engine that sits outdoors and runs a few minutes a week. Neglected, it will fail on the day it is needed. Generator maintenance service is not an upsell here; it is the reason a unit actually starts during the storm.

Annual and seasonal service covers:

Oil, filter, and spark plug replacement at manufacturer intervals, plus load bank testing where appropriate

Battery testing and replacement, the single most common cause of a no-start

Fuel system inspection, including propane regulator function and line pressure

Verification of the weekly exercise cycle and review of stored error codes

Monitoring, alerts, and remote status app setup so problems surface early

Units that crank but will not start almost always come down to fuel delivery, a weak battery, or a control fault, and all three are catchable during scheduled service. Our yearly membership plan puts that visit on the calendar automatically, and emergency generator service in Marshall County, AL is available when a unit fails mid-outage.

Scheduled generator, heating, and cooling service can be bundled into one annual agreement, described on our Membership Plan page.

A load assessment and recommended generator size with reasoning you can see

Fuel options priced for your address, natural gas or propane

Placement plan with clearances, noise, and prevailing wind considered

A free written estimate plus generator cost ranges and GoodLeap financing terms

Enrollment in scheduled maintenance from the day the unit is commissioned

Frequently Asked Questions

Total cost depends on generator size, fuel type, pad and gas line distance, and transfer switch requirements. Smaller managed load systems cost considerably less than full coverage units. Every quote is free, itemized, and financeable.

Most homes here land in a range that covers the air conditioner, well pump, kitchen, and general circuits, but the correct number comes from the load calculation. Starting current on the largest motor usually sets the minimum.

Yes, when it is sized for those starting loads or paired with load management. We verify pump horsepower and compressor draw before recommending a unit so nothing trips at startup.

Typically within seconds. The controller confirms the outage, starts the engine, and the transfer switch moves the house over once output is stable, so most homeowners notice only a brief blink.

Yes. Our line is answered live around the clock, and 24-hour generator repair in Guntersville, AL is dispatched during outage events when standby units fail under load.

Once a year at minimum, with heavier-use units serviced more often. Humidity and heat here are hard on batteries and rubber components, so annual inspection is the practical baseline.

If natural gas is at the property, it is usually the simpler choice with no tank to refill. Propane is standard on rural and lake lots without gas service, and tank size then becomes part of the planning.

We do. Our Huntsville office on Whitesburg Drive covers Madison County with the same licensed crews, permitting process, and maintenance program.
