What’s Included in a Professional Generator Installation?
When you partner with a licensed installer like Astro Gen, your quote covers the complete, turnkey process of getting your backup power system running. A professional installation includes:
- On-Site Load Calculation: Determining the exact size generator your home needs to power everything from your AC unit to your sensitive electronics.
- The Generator Itself: We help you select the best unit for your needs from trusted brands like Generac and Cummins.
- Automatic Transfer Switch (ATS): The brains of the system that automatically and safely switches your home’s power from the grid to the generator during an outage.
- Site Preparation: This includes pouring a concrete pad or installing a prefabricated one to ensure the generator is stable, level, and meets all code requirements.
- Fuel Line Connection: Running a dedicated line from your home’s natural gas meter or propane tank to the generator.
- Electrical Wiring: All the necessary high and low-voltage wiring to connect the transfer switch to your main electrical panel and the generator.
- Permits and Inspections: We handle all the necessary permitting with the City of Houston or your local municipality to ensure your installation is 100% compliant.
- System Activation and Testing: Once installed, we start up the generator, simulate a power outage, and verify that the system performs exactly as it should.
Key Factors That Influence Your Total Installation Cost
Several key variables determine the final price of your whole home generator installation. Understanding them will help you see where your money is going.
- Generator Size (Kilowatts): This is the biggest cost factor. A smaller 10kW unit that powers only essential circuits will cost less than a larger 22kW or 26kW model designed to run your entire home, including multiple central AC units. We perform a detailed load calculation to recommend the right size for you.
- Generator Brand and Model: Prices vary between top-tier brands like Generac and Cummins. Features like Wi-Fi monitoring, all-aluminum enclosures, and quieter operation can also influence the cost.
- Type of Automatic Transfer Switch (ATS): You can choose a “service-rated” ATS that replaces your main breaker panel or a standard ATS that is installed alongside it. The complexity of integrating the ATS with your home’s electrical system can affect the labor cost.
- Fuel Source: Connecting to a natural gas line is typically more straightforward and cost-effective if your meter is close to the generator’s location. Using a propane tank requires a large, dedicated tank and additional plumbing, which can increase the overall cost.
- Generator Placement and Site Prep: The location of the generator matters. A unit placed far from your gas meter and electrical panel will require more trenching, piping, and wiring, increasing labor and material costs. Complex site prep, like building a small retaining wall on a sloped yard, can also add to the price.
- Permitting and Code Requirements: Permit fees vary by location. Additionally, some areas have specific regulations, such as requiring the generator to be raised on a platform in flood-prone zones, which can impact the final cost.

Mistakes to Avoid When Getting Generator Quotes
Price is important, but it shouldn’t be the only factor. Here are a few common mistakes we help our customers avoid:
- Choosing an Undersized Generator: A generator that’s too small will struggle to power your essentials and can suffer from premature failure. A proper load calculation is crucial.
- Hiring an Unlicensed or Uninsured Installer: This puts you at risk for property damage, liability for injuries, and a failed inspection. Always verify credentials.
- Ignoring Permitting Requirements: Skipping permits can lead to significant fines, voided homeowners insurance, and trouble when you try to sell your home. A professional handles this for you.
- Focusing Only on the Upfront Cost: A cheap installation often leads to expensive repairs down the road. Investing in a quality installation from a reputable company saves you money and stress in the long run.
Generator Installation FAQs
How long does it take to install a whole-home generator? Most standard installations are completed in one to two days. The entire process, from consultation to final inspection, typically takes a few weeks, depending on permitting timelines.
Can I run my central air conditioner on a generator? Yes, but the generator must be properly sized to handle the high startup load of the AC unit. This is something we determine during our on-site assessment.
Do I have to be home for the installation? We ask that you are home at the beginning of the project to confirm the generator placement and at the end for the final walkthrough and system orientation.
What kind of maintenance does a generator require? Like a car engine, generators need regular maintenance, including oil changes and filter replacements. We offer comprehensive maintenance plans to keep your system in peak condition.
