Yes. When utility power is lost, the system detects the outage and starts automatically within seconds. When power is restored, the system shuts off and switches back on its own.

Portable generators require manual setup and limited circuits. Whole-home standby generators are permanently installed, automatic, and can power most or all of the home.

Most Houston homes use 18–26kW systems for full-home coverage. Larger homes with multiple A/C units or pool equipment may require 36–48kW with load management. We handle sizing during your consultation.

Yes. Arieli Custom Homes is a registered Generac dealer and authorized service provider, which allows us to perform authorized warranty work when applicable.

Over the years, we’ve installed standby generators as part of custom homes, renovations, and flood-zone projects. We’ve also spent significant time diagnosing, correcting, and improving generator installations — including systems installed by other contractors.
As builders, we look at generators as part of the home, not just standalone equipment. Our focus is on proper sizing, correct installation, and long-term reliability.

Because we are builders, we consider how a generator integrates with the home’s electrical systems, structure, site conditions, and future maintenance needs. We’ve seen common issues that arise when installations are rushed or poorly coordinated, and our process is designed to avoid those problems.

Yes. Flood-zone installations require additional planning, such as elevated pads and code-compliant placement. We have experience designing and installing generator systems in flood-prone areas.

It can. Generator size, placement, and mounting requirements may differ depending on flood-zone regulations. We take these factors into account during planning.
