Expert Whole-Home Generator Services in Huntsville and North Alabama

A standby generator starts on its own when the power goes out. It supplies electricity to the circuits chosen for backup, from the refrigerator and lights to larger equipment if the generator has enough capacity.

Blake Brothers installs and services whole-home generators in Huntsville and North Alabama. We help you plan what stays powered during an outage, then install the equipment to support those needs.

How Does a Whole-Home Generator Work?

A standby generator sits outside and connects to your home's electrical system through a transfer switch. When utility power fails, the generator starts. The switch separates your house from the utility lines before allowing generator power through.

When power returns and stays steady, the switch reconnects your house to the utility. The generator shuts down after cooling off. Expect a short break in power while it starts and transfers the load.

What Can a Whole-Home Generator Power?

Some homeowners back up only the essentials. Others want their AC and more of the house running during an outage.

Common choices are:

• Refrigerators and freezers
• Lights and selected outlets
• Internet and home office equipment
• Heating and cooling equipment
• Kitchen appliances
• Equipment used for medical care

Your AC uses extra electricity when its motor starts. We account for that demand when choosing generator capacity. Equipment that cannot lose power even briefly needs a separate battery backup.

Generator Installation

We start with the circuits you want powered and check your home's electrical setup. Next come the outdoor location, fuel connection, transfer switch, and generator installation. Before leaving, we test the system and show you how to read its controls.

Generator Repair

A generator that won't start, stops during a test, or shows a warning code needs repair. Grinding noises and trouble supplying power are other signs. Blake Brothers provides generator repair for these faults. Leave electrical and fuel connections to a technician.

Generator Maintenance

Oil, filters, and batteries need regular service. During generator maintenance, we check the engine, fuel supply, and automatic starting system according to the manufacturer's schedule.

What Size Generator Does Your Home Need?

A refrigerator and a few lights need far less power than central AC, an electric water heater, and an oven running together. We'll calculate the load for your chosen circuits, including the extra power motors need when they start.

Make a list of the appliances you want available during an outage. That gives us a useful starting point for choosing the equipment.

Natural Gas vs. Propane Generators

Natural gas models connect to a gas line. They depend on adequate pressure and continued utility gas service.

Propane models draw from a tank on your property. How long they run depends on the amount of fuel stored and how much electricity the house uses. Tank placement and available fuel supply are part of the installation plan.

Why Generator Maintenance Matters

A weak battery can stop a generator from starting. Dirty filters, old oil, or fuel trouble can affect it once running. Regular service catches some of these problems before an outage, though it cannot prevent every failure.

Generator Service Before Severe Weather

Ahead of North Alabama's storm season, check the display for warning lights and make sure scheduled service is current. Keep the outdoor unit clear as the manufacturer directs. For propane, check the tank level.

It's useful to know which outlets and appliances have backup power before the lights go out.
