Why a generator (Houston use cases)
Storms, heat, and long repair windows can make outages more than an inconvenience. A correctly installed system keeps essentials on—refrigeration, network, medical devices, sump, select HVAC—without extension-cord spaghetti. We’ll match the solution to your home and budget, from portable generator hookups to whole-home standby systems.
Not sure what you need? Call now and we’ll talk through options in minutes.
Standby installation & replacements
Looking for a low-touch solution that starts itself? A standby generator (with automatic transfer switch) can power selected circuits or your whole home.
- Right-sizing for your priorities (kitchen, office, primary suite, circulation air, etc.)
- New installs & replacements of aging units with more efficient models
- Concrete pad, clearances, exhaust direction, and sound considerations
- Gas line/electrical coordination and permit handling
- Startup testing and homeowner orientation
If your existing unit isn’t worth fixing, we’ll price a generator replacement side-by-side with repair so you can choose with confidence.
Transfer switches & interlocks
Safe switching is everything. We install manual and automatic transfer switches as well as interlock kits that let a portable generator feed selected circuits without backfeeding the grid.
- Panel-mounted interlocks matched to your breaker model
- Manual transfer switches for essential circuits (simple and reliable)
- Automatic transfer switches paired with standby generators
- Clear labeling and a quick-start card so anyone in the home can operate it
Unsure which approach fits? We’ll recommend the safest, simplest setup for your panel and goals.
Generator repair & maintenance
If your generator won’t start, surges, or trips under load, we can help. Our generator repair in Houston covers:
- No-start diagnostics (battery, fuel, controller)
- Voltage/frequency irregularities and load issues
- Transfer switch faults and control wiring
- Routine service: oil/filter, plugs, and test-runs on schedule
We’ll get you back to reliable—and note any parts nearing end-of-life so you’re not surprised later.
Sizing, load management & panel work
Backup power is about priorities and realism. We’ll map what you want running and size accordingly.
- Load calculation for essential circuits vs. whole-home coverage
- Load-shed strategies so the generator isn’t overtaxed
- Panel updates or subpanel for “generator-ready” circuits
- Space planning for the transfer switch and breaker positions
- If service capacity is the bottleneck, we’ll pair with a service upgrade (see Service Upgrades) and coordinate any required permits
Pricing & timelines
- Upfront, itemized pricing for hookup, switchgear, and any panel/service work
- Typical timelines: portable hookups and manual switches are quick; standby installs include permits and utility/gas coordination
- Clear expectations for noise, pad placement, and maintenance intervals
