Introduction

When a hurricane hits Houston or the grid freezes over, you have two choices. You can go out in the rain to drag a portable generator out of the garage, hunt for gasoline, and run dangerous extension cords through your windows. Or, you can sit comfortably on your couch and wait 10 seconds for your Blackmon Standby Generator to take over.

At Blackmon Plumbing, we specialize in Automatic Standby Power. These aren’t temporary patches; they are permanent appliances hooked directly to your home’s natural gas supply. We are Authorized Generac Dealers who ensure that when CenterPoint goes down, your home stays up.

The difference between a portable generator and an automatic standby system is the difference between a flashlight and a security system. One requires you to act; the other protects you whether you’re home or not.

How It Works: The Science of "Automatic"

The magic of a standby generator isn’t just the engine; it’s the brain. We install the Automatic Transfer Switch (ATS), which acts as the traffic controller for your home’s power.

Protecting Your Electronics: The "Clean Power" Advantage

Not all electricity is created equal. Portable generators often produce “dirty power” with high harmonic distortion, which can fry the circuit boards in smart refrigerators, LED TVs, and computers.

True Power™ Technology: We install Generac Guardian Series units that deliver utility-grade power with less than 5% total harmonic distortion (THD). This is the same power quality you get from CenterPoint Energy, ensuring your sensitive electronics are protected.

Brownout Protection: In Houston, the grid often fluctuates (brownouts) before failing completely. These voltage drops—where your lights dim but don’t go out—are actually more dangerous to electronics than a complete outage. Our systems detect these dangerous voltage drops and switch to stable generator power before your appliances are damaged.

What We Carry on the Truck (Reliability Components)

A backup generator is only “backup” if it actually starts. Our Mobile Warehouses carry the components that ensure reliability in extreme weather.

Portable vs. Automatic Standby: The Safety Gap

Many homeowners ask, “Can’t I just use a portable generator?” You can, but it comes with significant risks that most people don’t consider until it’s too late.

The Carbon Monoxide Reality

Portable generators kill people every year through carbon monoxide poisoning. Homeowners place them too close to windows or garages, thinking they have adequate ventilation. CO is odorless and deadly.

Standby generators are installed in permanent locations that meet strict clearance requirements from windows, doors, and air intakes. The installation is inspected and permitted by the city specifically to prevent CO incidents.

Why This Matters for Houston Homeowners

During the 2021 winter storm, many homeowners who managed to keep their homes powered with portable generators later discovered that their smart appliances had been damaged by inconsistent voltage. A $500 portable generator ended up costing them $3,000 in ruined electronics.

Standby generators with True Power™ technology deliver consistent, clean electricity that protects your investment in modern appliances.

The "Fuel-First" Difference

Why buy your backup generator from a Plumber? Because an engine without fuel is a paperweight.

Maintenance: The "Weekly Exercise"

Your Generac unit takes care of itself better than most homeowners take care of their cars. We program it to perform a Weekly Exercise—a self-diagnostic test run at low speed for 5-10 minutes.

What Happens During the Weekly Test

  • Self-Testing: The unit checks its own oil pressure, battery voltage, coolant temperature (on liquid-cooled models), and control board functionality.

  • Quiet-Test Mode: Modern Generac units run the exercise at reduced RPM, making them barely louder than your air conditioner.

Control from Anywhere: The Mobile Link™ App

The best part of an automatic system? You don’t have to be home to know it’s working.

The Vacation Scenario: You are on vacation in Florida when Hurricane season hits Houston. Instead of worrying if your sump pump is running or if the freezer is melting, you simply check your phone.

Real-Time Status: The app tells you exactly what’s happening: “Utility Power Lost. Generator Running. All Systems Normal.” You can monitor runtime, verify the system started properly, and receive alerts if any issues develop.

Dealer Monitoring: As Authorized Dealers, we can (with your permission) see your system’s status remotely. If your unit shows a “Red Light” error code during the weekly exercise, we often know about it before you do. We’ll call you to schedule service before the problem becomes critical during an actual outage.

Historical Data: The app tracks every exercise cycle, every power outage, and total runtime. This data helps us diagnose problems and predict maintenance needs.

Why the Exercise Matters

Engines that sit idle for months develop problems—fuel gumming, battery drain, and moisture buildup. The weekly exercise keeps the engine lubricated, the battery charged, and verifies that the ATS is functioning. This is why standby generators have 95%+ start reliability compared to portable generators that often fail when you need them most.

The Mobile Warehouse Advantage for Emergency Repairs

When your generator fails during an outage, you cannot wait three days for a part to be ordered. Our fully stocked box vans carry the critical components needed to restore your backup power system:

  • Control Boards: The brain of the ATS system. These fail more often than engines.
  • Contactors: The physical switches inside the transfer switch that route power.
  • AGM Batteries: The most common failure point on generators that haven’t been maintained.
  • Air Filters & Oil: For emergency maintenance during extended outages.
  • Gas Regulators & Valves: To troubleshoot fuel delivery issues on the spot.

This inventory allows us to restore your generator during the storm, not after it has passed and you’ve already lost hundreds of dollars in spoiled food.

Zone Logic: Weather-Specific Backup

Different areas of Houston face different reliability challenges when it comes to backup power:

The Transfer Switch: The Unsung Hero

Most people focus on the generator itself, but the Automatic Transfer Switch is equally critical. This is the device that makes the system “automatic.”

Financing: Making Backup Power Affordable

A whole-home automatic standby generator is a significant investment, typically ranging from $12,000 to $25,000 depending on size and complexity. We work with financing partners who specialize in home improvement projects.

Why It’s Worth It:

  • Food Savings: One multi-day outage can cost $500-$1,000 in spoiled food
  • Home Office: Remote workers lose income during outages
  • Medical Equipment: Essential for families with CPAP machines, oxygen concentrators, or refrigerated medications

Home Value: Backup generators increase property value and appeal to buyers in hurricane-prone markets

Common Questions About Whole-Home Generators

Edit with Bricks

Q: Does it power the whole house?

A: It depends on the size (kW rating) you choose. We can configure the system two ways:

Whole-Home Solution: Powers everything simultaneously, including central A/C. Requires 22kW-48kW depending on your home size.
Load-Managed Solution: Powers critical circuits (lights, refrigerator, some outlets, garage door) and uses a “load shed” module to cycle heavy loads like A/C. Requires 14kW-20kW.

We perform a Load Calculation at your home to determine which approach fits your needs and budget.

Q: Does it run on Natural Gas or Propane?

A: Generac units can run on either fuel source. Most Houston-area homes use Natural Gas because it’s available from CenterPoint Energy’s underground infrastructure (endless supply). Rural properties typically use Propane from a large tank (500+ gallons).

The advantage of natural gas is you never run out. The advantage of propane is slightly higher efficiency and independence from utility infrastructure.

Q: Is it loud?

A: Modern Generac units are significantly quieter than portable generators:

Portable Generator: 70-90 dB (sounds like a lawn mower)
Standby Generator: 60-65 dB (sounds like a normal conversation)

During the weekly exercise, they operate in Quiet-Test mode at reduced RPM, making them barely noticeable. Under full load during an outage, they’re about as loud as your outdoor AC condenser unit.

Q: How long does it run before needing service?

A: We recommend professional service every 200 hours of run time or annually, whichever comes first. Most homeowners never hit 200 hours unless they experience a major multi-day outage.

During the annual service, we change the oil, replace the air filter, check the spark plugs, test the battery, and verify the transfer switch operates correctly.

Q: What happens if the generator fails during an outage?

A: This is where our Mobile Warehouse model proves its value. We dispatch a fully stocked van with replacement parts (batteries, control boards, contactors) to restore your power during the storm. Most generator companies don’t offer emergency service during outages because they don’t stock parts.

Q: Can you take over maintenance on a generator another company installed?

A: Yes. As Authorized Generac Dealers, we can service any Generac unit regardless of who installed it. Many customers come to us after their original installer went out of business or stopped responding to service calls.

Q: Do I need a permit?

A: Yes. Generator installations require electrical and gas permits from your city. We handle all permitting and coordinate the required inspections. This is why we recommend using a licensed contractor rather than attempting DIY installation.

Secure Your Peace of Mind

Don’t wait for the lights to go out. Install a system that watches over your home 24/7, starts automatically, and keeps your family comfortable whether you’re home or away.

The difference between having backup power and not having it is the difference between an inconvenience and a crisis.
