What We Do

Standby power, maintained to the standard it was engineered for.

One team for maintenance, testing, and repair — across residential estates, commercial properties, and industrial sites.

  • Annual Preventive Maintenance

    Full synthetic oil, OEM filters and plugs, and a documented multi-point inspection that keeps your unit outage-ready.

  • Load Bank & Transfer Switch Testing

    We verify your generator carries real load and that the automatic transfer switch hands off cleanly, every time.

  • Fuel System Testing & Polishing

    Diesel polishing, propane and natural gas pressure verification, regulator checks, and contamination testing.

  • Battery & Starting System Checks

    The #1 cause of a no-start during an outage. We load-test, clean terminals, and verify charger output.

  • Emergency Repair

    Diagnostics and repair for controllers, alternators, cooling, and fuel systems — with priority dispatch for members.

  • Home Protection Plans

    Recurring membership with scheduled visits, discounted repairs, and a digital maintenance history you actually own.

Why It Matters

An untested generator is a very expensive assumption.

  • NFPA 110 compliance

    Emergency power systems require documented periodic inspection and load testing. We test to standard and give you the paperwork.

  • Insurance & warranty requirements

    Most manufacturer warranties and commercial policies require proof of annual service. Missing records can void a claim.

  • Failure happens under load

    A generator that idles fine can still fail the moment the grid drops. Load and transfer testing is the only real proof.

  • Extends generator lifespan

    Clean oil, healthy batteries, and stable fuel routinely add years of reliable service to a standby unit.

Client Experience

Trusted with the homes that can't go dark.

  • They treat your generator like it's their own. The technician walked me through every reading and left the pad cleaner than he found it.

  • We lost power three times last winter and never noticed. That's exactly what I'm paying for — it just works, every time.

  • Our building's transfer switch failed inspection twice with the last vendor. These guys documented everything and we passed clean.
