Our Whole House Generator Installation Process
Step 1: On-Site Consultation & Sizing
We begin with a thorough on-site assessment of your home's power requirements. Our licensed technicians calculate your electrical load and help you select the perfect Generac generator for your needs and budget. We bring sizing charts and specifications with us—no return trips for measurements.
Step 2: Site Preparation & Concrete Pad
Our team prepares the installation location by pouring a professional, level concrete pad. We ensure a stable and secure foundation for your new generator. Proper grading and drainage protect your investment from Houston's heavy rainfall.
Step 3: Generator Placement & Gas Line Installation
We expertly position the generator and our licensed plumbers install the correctly sized natural gas or propane line. MPL-38162 — Texas Responsible Master Plumber ensures safe, code-compliant fuel connections. We carry gas fittings and regulators on every truck.
Step 4: Automatic Transfer Switch & Electrical
Our certified electricians install the automatic transfer switch (ATS) and seamlessly connect the generator to your home's electrical panel. The system automatically detects power outages and restores electricity within seconds. We don't chase parts. We bring them with us.
Step 5: System Activation & Walkthrough
We activate the system and simulate a power outage to test performance under real conditions. Our technicians provide a complete walkthrough so you understand startup sequences, maintenance schedules, and monitoring features. Permanent repair, permanent solution.
Step 6: Permitting & Final Inspection
We manage the entire permitting process and coordinate with city inspectors for final approval. Your installation meets all local codes and regulations. Flat-rate, upfront pricing covers permits and inspection fees—no surprise charges after completion.
Generac Generator Options for Your Home
Air-Cooled Generators
The most popular choice for residential homes. These units provide reliable power for essential circuits or the entire house in a compact, efficient package. Perfect for standard power requirements without the complexity of liquid cooling systems.
Liquid-Cooled Generators
Ideal for larger luxury homes or properties with high power demands. These generators offer more robust performance and quieter operation. Built for extended runtime when you need maximum power output.
Natural Gas & Propane Fuel Options
We connect your generator to your home's existing natural gas line for continuous fuel supply. No refilling required. We also install connections for liquid propane (LP) tanks when natural gas isn't available at your property.
Automatic Transfer Switches (ATS)
Choose between a whole-house transfer switch to power everything automatically. Or select a load-shedding switch to manage only your most critical circuits. Both options eliminate manual switching during power outages.

Our mobile warehouse carries all standard installation components including transfer switches, electrical panels, and gas fittings. We don't chase parts. We bring them with us.
Most Texas homes require 20kW to 24kW generators to power essential circuits including HVAC, refrigeration, and lighting. Larger homes with electric water heaters or pool equipment need 26kW or higher capacity units.
We calculate your exact load requirements during our on-site assessment. Our MPL-38162 licensed technicians measure your electrical panel's total amperage and identify critical circuits for seamless power transfer.
Complete Generac installation takes 6-8 hours for standard residential setups. This includes concrete pad preparation, natural gas line connection, electrical panel integration, and automatic transfer switch installation.
We dispatch fully stocked mobile warehouses with all required materials and specialty tools. One trip. Done. No return visits for missing components or additional parts runs.
The automatic transfer switch monitors your utility power and instantly switches your home to generator power during outages. It disconnects utility lines and connects generator circuits within 10 seconds of power loss.
When utility power returns, the transfer switch automatically reconnects your home to the grid and signals the generator to shut down. No manual intervention required—complete hands-off operation for permanent backup power protection.
Generac generators require annual maintenance including oil changes, air filter replacement, and battery testing. Houston's humidity and heat accelerate component wear, making consistent service critical for reliable emergency operation.
We provide comprehensive generator maintenance with genuine Generac parts carried in our mobile warehouse. Our technicians test transfer switch operation, inspect gas connections, and verify automatic startup sequences for permanent reliability.
