Frequently Asked Questions
How much does a whole-house generator cost in Texas?
A fully installed whole-house standby generator in Texas costs $5,000 to $16,000 depending on the power capacity. A 10-14 kW unit suitable for smaller homes runs $5,000 to $8,000 installed. Mid-range 16-20 kW units cost $7,000 to $12,000. Larger 22-26 kW units for homes needing full HVAC backup range from $10,000 to $16,000. These prices include the generator, automatic transfer switch, concrete pad, gas line connection, permits, and inspection.
What size generator do I need for my Texas home?
Generator sizing depends on what you want to power during an outage. To run essential circuits like refrigerator, lights, outlets, and a window AC unit, a 10-14 kW unit suffices. To power your central AC system, which is critical in Texas summers, you typically need at least 16-20 kW. For whole-house coverage including HVAC, water heater, and all circuits, 22 kW or larger is recommended. An electrician performs a load calculation to determine the exact size needed.
How long does generator installation take?
A typical whole-house standby generator installation takes one to two days. Day one involves pouring or placing the concrete pad, setting the generator, running the gas line, and installing the automatic transfer switch at the electrical panel. Day two covers electrical connections, programming, testing, and final inspection. If a permit inspection is required, the generator may need to wait one to three business days for the inspector visit before being commissioned.
Do I need a permit for a generator in Texas?
Yes, most Texas municipalities require permits for standby generator installation because it involves electrical panel modifications, a new gas line, and placement of outdoor equipment. The permit process ensures the installation meets NEC electrical codes, local gas codes, and setback requirements from property lines and structures. Your licensed electrician and plumber (if a separate gas line permit is needed) should handle all permitting and inspections.
Natural gas or propane -- which is better for a Texas generator?
Natural gas is preferred if your home has a city gas connection because it provides an unlimited fuel supply, meaning your generator runs as long as the outage lasts without refueling. Propane is the choice for rural homes without gas service, but requires a large enough tank, typically 250 to 500 gallons for extended outages. Propane generators produce slightly more power per unit of fuel. Many generators are dual-fuel capable, accepting either source.
How does an automatic transfer switch work?
An automatic transfer switch (ATS) monitors your utility power 24/7. When it detects a power outage, it sends a start signal to the generator. Once the generator reaches stable operating speed, usually within 10 to 30 seconds, the ATS transfers your home's electrical load from the utility to the generator. When utility power is restored, the ATS transfers the load back and signals the generator to shut down after a cool-down period. No manual intervention is needed.
