- WHAT WE LOOK AT
What we look at on a job like this
01
Whole home standby with ATS as the typical scope
Most Austin installs are whole-home automatic standby units, not portable interlocks.
02
Fuel by location: gas in city, LP in Hill Country
Built-up areas use natural gas; Hill Country and rural-edge use LP with on-site tanks.
03
Freeze-event sizing per NEC 220
Sizing accounts for heat-pump auxiliary heat and sustained loads during multi-day events.
04
Surge protection paired with install
Whole-house SPD installed at the panel as part of most generator projects.
05
Lead time management for equipment
Lead times run 4 to 12 weeks in normal conditions and longer after major events. We confirm at quote.

Permits
Permits and inspections
Not every job requires a permit. When the local AHJ requires one, we pull it, schedule the inspection, and stay with the job until it passes. No paperwork on you.
Warranty
What's covered
Written warranty: 5-year on outlets, fixtures, and EV chargers; 10-year on wire and breakers; lifetime on panelboxes and surge protection. Parts and labor. Transfers with the home.

- TX SPECIFIC · AUSTIN METRO
What is different about generator and backup power in Texas.
Some of what we do for generator and backup power is shaped by the codes and conditions specific to Texas. Here is what tends to differ versus other states.
Code adoption in Texas
Texas adopts the National Electrical Code at the state level through the Texas Department of Licensing and Regulation, with most cities in the Austin metro adopting the most recent NEC cycle within a year or two of publication. Round Rock, Cedar Park, Pflugerville, and Austin proper each maintain their own permitting offices with slightly different inspection scheduling and form workflows. We track which cycle each AHJ in our coverage area is currently enforcing, so the scope we write for a job in Cedar Park is current to that city, not just current to "Texas." When a project crosses jurisdictions or sits in unincorporated county, we route the permit through the correct authority and tell you upfront which inspection cadence applies.
Hot-climate considerations
Central Texas summers run long and hot, and that affects generator and backup power in ways that are easy to underestimate. Panels mounted on west-facing exterior walls run hotter all afternoon. Attic-mounted equipment derates per code because ambient attic temperatures regularly clear 130°F. AC compressors pull near-rated current for hours at a stretch through July and August, which puts more thermal cycling on terminations than the same equipment would see in a milder climate. We size conductors and breakers with that summer load profile in mind, not just the nameplate minimum. On older homes we look closely at terminations that may have loosened from years of heat cycling, those are a common cause of intermittent issues that get misdiagnosed elsewhere.
Severe weather and storm response
The metro sees thunderstorm hail, the occasional derecho, and the post-storm spike in generator and surge-protection demand that comes with each event. We keep enough surge-protection inventory at the shop to swap out a damaged whole-home unit same-day after a strike, and we know which generator and transfer-switch SKUs are realistic to source quickly when the supply chain tightens after a regional event. After the 2021 winter storm we also got a lot more careful about which loads customers actually need on backup, versus which loads end up on the generator only because nobody asked the question at install time.

- WHO TO HIRE
Why hiring a licensed electrician matters.
For generator and backup power, here's the honest comparison. We'd tell you the same thing if we weren't trying to win the job.
Keil Electric
A licensed electrician
Licensed electrician walks every job. Veteran-owned, family-run.
Permits pulled and inspections coordinated when required by the AHJ
5/10-year + lifetime warranty in writing. Parts and labor. Transfers with the home.
Fully insured + workers' comp on every crew
The price you sign is the price you pay
A handyman
Unlicensed for electrical
No state electrical license. Can do simple swaps but not panel work, rewires, or service upgrades.
No permits. Work won't pass inspection if the city audits it later.
No structured warranty. "Call me if something breaks" isn't enforceable.
If something they did causes a fire, your homeowner's insurance can deny the claim.
Cash discount may show up on the invoice.
DIY
Doing it yourself
Cheap, but only if everything goes right. Most electrical work involves load calc, code, and permitting.
A failed inspection means redoing the work. Selling the home later, the buyer's inspector flags it.
No warranty if something fails. Replacement is on you.
Live wiring is a real safety hazard. Most fatal home electrical accidents are DIY.
If you know what you're doing, fine. If you don't, call us first.
The Austin metro has the highest residential generator demand we see across both shops. The February 2021 freeze permanently changed how Texans think about backup power. Subsequent freeze events, summer ERCOT grid alerts, and severe-weather frequency have kept generator demand high. Lead times on whole-home units run 4 to 12 weeks in normal conditions and longer after major events.
Whole home standby is the typical scope
Most Austin metro generator installs are whole-home standby units (Generac, Kohler, Cummins) on natural gas or LP, with automatic transfer switches that handle the loads automatically during outages. The investment makes sense for homeowners who experienced multi-day outages during the 2021 freeze and don’t want to manage portable equipment.
Natural gas in city, LP in Hill Country
Austin, Round Rock, Cedar Park, Pflugerville, and other built-up areas have natural gas service from major utilities (Atmos, Texas Gas Service). Hill Country and rural-edge properties (Wimberley, Marble Falls, Llano, Mason, Burnet) usually don’t have gas service and use LP with on-site tanks (typically 250 to 500 gallons for residential).
Freeze-event sizing considerations
Generator sizing in Texas accounts for freeze-event load patterns: heat-pump heating (sometimes auxiliary resistance heat), water heater, electric range, and sustained refrigeration. We run NEC 220 demand calc with freeze-event loads in mind, which often pushes sizing one step up from what a similar home in a milder climate would need.
Surge protection paired with generator installs
Generator installs in the Austin market are usually paired with whole-house surge protection at the panel. The surge frequency from severe weather and grid switching events is high, and the surge protector adds protection for the generator electronics, the ATS, and the loads during transitions.

Common questions for Generator and backup power in Austin, TX
Whole home generator versus interlock kit - which makes sense?
A whole home standby generator is automatic, runs on natural gas or LP, and powers selected (or all) circuits during an outage. An interlock kit lets a portable generator safely back-feed the panel through a breaker. Whole home is more expensive and hands-off; interlock is cheaper and requires you to start the generator manually.
What size generator do I need?
Generator sizing starts with the loads you want to keep on (HVAC, refrigeration, well pump, medical equipment, lighting). We run the load calculation and recommend a size that matches without oversizing.
Where does a standby generator typically sit?
Outside the home on a concrete pad, away from windows and air intakes per manufacturer and code clearance rules. We confirm the pad location during the site visit.
Does a standby generator need a permit?
Yes - both the electrical interconnect and the gas connection (or fuel storage for LP) typically require permits and inspection. We handle the permit application as part of the project.
How long does a whole home generator install take?
A typical install runs 2-4 days on site once the equipment arrives, plus permit and inspection scheduling. Larger or more complex projects can extend; we confirm the timeline in the written scope.
