How to Prepare Your Home Generator Before Hurricane Season in Houston

Hurricane season runs June 1 through November 30 along the Gulf Coast — and Houston sits right in the path. Hurricane Beryl gave Houstonians barely 48 hours of warning before knocking out power for more than 2.7 million customers. A serious storm doesn't always give you days of notice.

If you already own a standby generator, the worst time to discover a problem with it is during an actual outage. Here's the complete checklist to make sure yours is ready before storm season ramps up — plus what to do if you don't have one yet.

If You Already Have a Generator: The Pre-Season Checklist

1. Schedule Your Annual Maintenance Service

This is the single most important step, and it's the one most homeowners skip. A proper pre-season service should include:

• Oil and filter change — especially important if your unit hasn't run since last season

• Spark plug inspection/replacement

• Battery testing — heat is the number one killer of generator batteries in Houston, and a weak battery means your generator may not start when you need it most

• Full load bank test — this simulates a total power outage to confirm your generator can actually handle your home's full electrical demand, not just turn on

Standby generators run a brief automatic self-test weekly, but that's not the same as a full load test. A unit can pass its self-test and still fail under real demand.

2. Verify Your Fuel Source Is Ready

If you're on natural gas, this is largely automatic — Houston's underground gas infrastructure is one of the most reliable utilities during a hurricane, unlike electricity and gasoline supply, which are frequently disrupted.

If you're on propane, confirm your tank level now, before the season ramps up. Propane suppliers get slammed with refill requests once a storm enters the forecast, and trucks may not be able to reach your home if roads are flooded or blocked.

3. Check the Physical Installation Area

• Clear any debris, overgrown vegetation, or stored items around the generator enclosure

• Confirm the area has good drainage — Houston's clay soil and heavy rainfall can pool water around the unit if drainage wasn't properly addressed during installation

• Inspect the concrete pad for cracks or shifting

4. Test the Automatic Transfer Switch

The transfer switch is what detects a power loss and switches your home to generator power automatically, usually within seconds. If you haven't tested it recently, this is the time. Your installer or maintenance provider can verify it's functioning correctly during your annual service visit.

5. Confirm Your Monitoring App Is Connected

If your generator has app-based remote monitoring (most Generac and Briggs & Stratton models do), make sure it's connected and you're receiving alerts. This lets you know about a maintenance issue before a storm — not after the power goes out and you discover the generator won't start.

During an Extended Outage: What to Know

Standby generators are designed to run for days or even weeks continuously, but a few things matter during a prolonged outage:

• Check oil levels every 24-48 hours during multi-day continuous operation

• Never run a portable generator indoors, in a garage, or near windows or doors — carbon monoxide poisoning is a serious and recurring risk after every major hurricane. This applies to portable units; properly installed whole-home standby generators are designed to vent safely outdoors, which is one of the major safety advantages of a permanent installation over a portable unit.

• Make sure carbon monoxide detectors inside your home have fresh batteries before the season starts

If You Don't Have a Generator Yet: Timing Matters

This is the part that catches a lot of Houston homeowners off guard. The installation timeline — from signed contract to fully operational system — typically runs 4 to 8 weeks, factoring in permitting, scheduling, and inspection.

That means if you wait until a storm is named and tracking toward the Gulf, it's already too late to have a generator installed before it arrives. Every year, our install calendar fills up fast in the weeks after the first major storm warning — and that's exactly the moment when it's no longer possible to get a system installed in time.

The right time to start the process is April or May — before the season's first real threat, while permitting and scheduling timelines are still manageable.

A Few Houston-Specific Risks Worth Knowing

Heat compounds the danger of a power outage. In Houston, losing power during a summer hurricane isn't just inconvenient — without air conditioning, indoor temperatures can become dangerous within hours, especially for elderly residents, young children, or anyone with medical conditions.

Food spoilage adds up fast. A multi-day outage during summer heat means a full refrigerator and freezer of food loss — often $300-$600 or more — on top of the inconvenience.

Medical equipment dependency. If anyone in your household relies on powered medical equipment (CPAP machines, oxygen concentrators, refrigerated medications), a generator isn't a convenience — it's a safety requirement.
