Storm Season Is Here — Is Your Generator Ready?

If you live in the Houston area, you already know the drill: tropical weather forms in the Gulf, and within days it can turn into wind, rain, and — for thousands of homes — a power outage. With a tropical system currently being tracked toward the Texas coast, now is the time to confirm your generator will actually do its job when you need it most.

The good news: if you already have a generator, getting "storm-ready" takes about five minutes. Here's exactly what to check.

1. Check the Indicator Light

Every Generac, Briggs & Stratton, or Champion generator has a status light on the side of the unit. Green means it's in standby mode and ready to activate automatically during an outage. Yellow/amber or red means the unit is flagging a warning that needs attention before the storm arrives — not during it.

2. Confirm Your Generator Is Completing Its Exercise Cycle

Most standby generators automatically run a short self-test every week to keep the engine lubricated and confirm the battery is healthy. If that cycle is running on schedule and the light is green, you're generally covered.

3. Not Sure? Run a Simple Storm Simulation Test

Turn off the main breaker at your transfer switch, let the generator run about 15 minutes, then turn the breaker back on and confirm the light returns to green. If it doesn't start, doesn't reach full power, or the light isn't green afterward, get it looked at before the storm — not after.

4. Check When Your Generator Was Last Serviced

Annual maintenance — fresh oil, a clean air filter, a battery check, a full diagnostic — is the single biggest factor in whether a generator starts on demand. If it's been more than a year since your last service or your maintenance contract has lapsed, that's worth fixing now just text us at 346-888-9393 and we'll get you scheduled.

How Long Will a Generator Run During a Houston Power Outage?

Estimated read time: 6 minutes

Last updated: July 2026 By PSL Technology LLC | Authorized Generac & Briggs and Stratton Dealer | Tomball, TX

After Hurricane Beryl knocked out power to over 2.7 million Houston-area customers in 2024 — with some neighborhoods waiting more than two weeks for restoration — the question every generator owner was asking was simple: how long can this thing actually run?

The answer depends on three things: your fuel source, your home's power load, and how well the unit is maintained. Here's the real breakdown, specific to how most Houston homes are set up.

Natural Gas: The Advantage for Houston Homeowners

Most homes in the Houston metro area are connected to natural gas service — and that's a significant advantage when it comes to generator runtime.

A whole-home standby generator connected to your natural gas line can run indefinitely, as long as the gas utility maintains service and pressure. There's no tank to empty, no delivery truck to schedule, and no running out of fuel on day 5 of an extended outage.

Here's something most people don't know: during major hurricanes and storms, Houston's underground natural gas infrastructure has historically remained operational even when the electrical grid was completely down. During Hurricane Katrina, natural gas service remained active across large parts of affected areas even as the power grid was destroyed. The gas distribution system is underground and largely protected from wind and storm damage — which is exactly why standby generators on natural gas are the gold standard for Houston homes.

Practical limit on natural gas: The limiting factor isn't fuel — it's oil. Most manufacturers recommend an oil change every 150 to 200 hours of continuous operation. Running 24 hours a day, that means your first oil change is due around day 6 to 8. With proper maintenance, a natural gas generator can run for weeks or even months during a catastrophic outage.

Propane: Runtime Depends on Your Tank Size

If your home uses propane instead of natural gas (common in newer developments and rural areas outside the metro), runtime is determined by how much fuel you have stored on-site.

Here's a realistic runtime table for common generator sizes at 50% load — which is typical for a Houston home running central AC, refrigeration, lights, and basic appliances:

Generator Size	Tank Size	Estimated Runtime at 50% Load
14kW	250-gallon tank	5–7 days
14kW	500-gallon tank	10–14 days
22kW	250-gallon tank	3–4 days
22kW	500-gallon tank	5–8 days
22kW	1,000-gallon tank	10–16 days

Keep in mind these are estimates at moderate load. On a mild day with lower AC demand, your generator runs below 50% load and fuel lasts longer. On a hot Houston summer day with multiple AC units running, consumption goes up.

Critical for propane users: Top off your tank before hurricane season starts — ideally in May or early June. Propane suppliers get slammed with refill requests once a storm enters the forecast, and delivery trucks may not be able to reach your home if roads are flooded. Never let your tank drop below 30% during storm season.

What Actually Limits Your Generator's Runtime

Oil — The Real Limiting Factor

Whether you're on natural gas or propane, the practical limit on continuous runtime is oil maintenance. Most residential standby generators require:

• Oil check every 24 hours during extended continuous operation

• Full oil change every 150–200 hours of runtime (roughly days 6–8 of continuous use)

Skipping oil changes during a prolonged outage risks engine damage that can shorten the life of your generator significantly. If you're planning to run through a multi-week outage, make sure you have extra oil on hand before storm season.

Air-Cooled vs. Liquid-Cooled Engines

Most residential standby generators (10–26kW Generac and Briggs & Stratton units) use air-cooled engines. These are designed to run continuously for around 500 hours before requiring a major service interval. For context, that's about 21 days of non-stop operation.

Larger liquid-cooled generators (typically commercial or large estate applications) can run 7–10 days continuously and are better suited to extremely prolonged outages, but they're also significantly more expensive and larger.

For the vast majority of Houston homes, an air-cooled 14–22kW standby generator on natural gas is more than capable of handling even a two-week outage comfortably.

How Much Power Does Your Home Actually Use During an Outage?

This is the question most homeowners don't think to ask — and it matters for runtime estimates.

Most homes don't run at 100% of their generator's rated capacity during an outage. Typical Houston home during an extended summer outage:

Appliance	Approximate Draw
Central AC (4-ton unit)	3,500–5,000 watts
Refrigerator	150–400 watts
Lights (10 LED bulbs)	60–100 watts
TV + devices	200–400 watts
Microwave (while in use)	1,000–1,500 watts
Typical total running load	5,000–8,000 watts

A 20kW generator running a typical Houston home at 5,000–8,000 watts is operating at roughly 25–40% of its rated capacity. That means fuel consumption is well below the "full load" figures you might see on spec sheets — and your runtime is correspondingly longer.

After the Outage: What to Do With Your Generator

Once power is restored, don't just shut your generator off and forget about it:

• Check and change the oil if you ran continuously for more than 100 hours

• Run a test cycle after the unit cools down to confirm it's ready for the next event

• Schedule a post-storm service if you noticed any performance issues during the outage — unusual noise, voltage fluctuations, or automatic shutdowns

  
  

Bottom Line for Houston Homeowners

If you're on natural gas — which most Houston-area homes are — a properly maintained whole-home standby generator can power your home through virtually any outage, from a 12-hour grid hiccup to a multi-week post-hurricane restoration. The fuel supply isn't the concern; the maintenance schedule is.

If you're on propane, size your tank appropriately for the outages your area typically experiences. For most of the Greater Houston area, a 500-gallon tank with a 20kW generator gives you a solid 5–8 days of runtime at normal summer loads — enough for most storm scenarios.

Not Sure What Size You Need for Your Home?

The right generator size depends on your home's square footage, your AC tonnage, and which appliances you need to run during an outage. We do a free load calculation during every in-home consultation — no guessing, no oversizing, no undersizing.

How to Prepare Your Home Generator Before Hurricane Season in Houston

Estimated read time: 6 minutes

Last updated: June 2026 By PSL Technology LLC | Authorized Generac & Briggs and Stratton Dealer | Tomball, TX

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.
