Right-sized backup power with clean, code-compliant hookups

Home Generators — Installation & Repair — Houston, TX

When the power drops, you want a plan that works. We provide home generator installation in Houston—clean, safe hookups with transfer switches or interlocks—plus generator repair and full replacements. Everything is sized, permitted, and labeled so your backup power is ready when you need it.

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.

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

FAQ’s

What’s the difference between a transfer switch and an interlock?

Both prevent backfeeding. Interlocks mount on your panel and use your main breaker; transfer switches are separate switchgear that route selected circuits to generator power. We install both—your panel and priorities determine the best choice.

Can I power my whole house?

Yes with the right size unit, but many homeowners choose essential-circuits coverage for efficiency. We’ll size it together.

Do I need permits?

Electrical work does; gas work typically does as well. We handle the paperwork and coordinate inspections.

Will my panel need changes?

Often we add spaces, a subpanel, or a labeled “generator” section. If capacity is tight, see our Electrical Panels and Service Upgrades pages.

How loud are standby generators?

Modern units are quieter, but placement matters. We’ll recommend locations that respect setbacks and your comfort.
