Frequently Asked Questions

Generac installation in Houston, answered

How do I get pricing for a Generac standby generator in Houston?
Every install is quoted after a free in-home assessment. Pricing depends on generator size, gas line work, electrical complexity, and your county’s permit fees. We provide one fixed all-in number — equipment, labor, permits, tax — with financing available for qualified homeowners. Request a free quote here.
How long does Generac installation take?
After permitting is approved (typically 1–3 weeks in Harris and Montgomery County), installation itself is generally 1–2 days. We handle all permitting on your behalf so you don’t have to coordinate with the county.
What size Generac do I need for my Houston home?
For most Houston homes 2,000–3,500 sq ft, a 22kW or 26kW air-cooled unit covers the entire home without load shedding. Larger or all-electric homes may need a 36kW or 48kW liquid-cooled unit. Our free assessment includes a load calculation so you only buy the size you actually need.
Do you handle the gas line and electrical permits?
Yes. We handle natural gas or propane connection, electrical work, transfer switch installation, and all permits and inspections required by your county and utility. You see one bill, work with one company, and have one point of contact.
Will my Generac come with a warranty?
Every Generac home standby unit ships with a 5-year limited warranty as standard. Extended 7-year and 10-year warranties are available at install. We also offer our own labor warranty on all installation work.
Do you finance Generac installations?
Yes. We work with multiple lenders to offer approved-credit financing on the equipment and installation, turning a one-time install cost into a manageable monthly payment. Visit our finance options page for details.
