FAQs
How long does installation take?
From permit approval to final startup, most residential installations take 1–2 days onsite.
That said, the full timeline usually looks like this:
- Consultation + system design: 1–3 days
- Permitting + utility coordination: ~1–3 weeks (varies by jurisdiction)
- Onsite installation: 1–2 days
- Final inspection + commissioning: shortly after install
Generator installs are a 32-step process, the prep work matters more than the physical install itself.
Do I need a permit in Houston?
Yes.
Houston and surrounding jurisdictions require permits for:
- Electrical work
- Gas work (natural gas or propane)
- Generator placement and connection
Good news: Generator Industries handles all permitting and inspections as part of the turnkey install, so homeowners don’t need to manage city paperwork themselves.
Can I power my AC?
Yes, in most cases.
Whole-home or properly managed systems can run central air conditioning, even in Texas heat.
Load management may be used to prioritize essential systems and prevent overload.
During the consultation, Generator Industries sizes the generator based on:
- Square footage
- AC tonnage
- Electrical load
- Lifestyle needs
This ensures reliable cooling without stressing the generator.
Natural gas vs propane in Texas?
Natural gas is usually the preferred option in Houston, but both work well.
Natural Gas
- Continuous fuel supply (no refills)
- Ideal for long outages
- Common in Houston neighborhoods
Propane
- Used when natural gas is unavailable
- Requires a storage tank
- Excellent reliability if tank is properly sized
Generator Industries designs systems around what’s available at your property, not a one-size-fits-all approach.
Where can the generator be placed?
Placement must meet local code, manufacturer clearance requirements, and utility rules.
Typical guidelines:
- Outside the home
- On a concrete or composite generator pad
- Proper distance from windows, doors, and vents
- Accessible for service
During the site visit, the installer confirms:
- Code compliance
- Noise considerations
- Aesthetics and property layout
All placement decisions are finalized before permitting is submitted.
What happens during final testing?
Final testing is when the system is proven reliable.
It includes:
- Utility power shut-off simulation
- Automatic Transfer Switch (ATS) verification
- Generator startup under load
- Voltage, frequency, and system checks
- Owner walkthrough and basic operation overview
The goal is simple:
When the grid fails, the generator starts automatically and powers what it’s supposed to.
From everyday electrical work to full standby generator systems, Generator Industries keeps Houston homes and businesses powered, protected, and ready for any storm.
