# Commercial Generator Repair — Booking & Missed-Call Recovery

*Booking, PM scheduling, and after-hours dispatch for commercial generator shops. Built for hospital and data center service contracts.*

## Commercial Generator Repair (Sun Belt — hurricane spike Jun–Nov)

Generator service is uptime-critical infrastructure work. A hospital, data center, or assisted-living facility with a failed backup gen is operating in code violation until it's fixed — and they pay any vendor who guarantees same-day response. The shops with 24/7 missed-call text-back, after-hours dispatch escalation, and automated PM reminders hold $50K/year service contracts. Everyone else is doing one-off Cummins QSK rebuilds at retail.

PM cadence is where the system pays for itself. A 75-unit commercial portfolio needs monthly load tests, semi-annual oil services, annual major PMs. Spreadsheet calendars drop one in twenty — and that one missed PM is the entire reason the backup gen failed Tuesday. Redline Revenue's calendar-based PM scheduling handles it.

Tickets: Cummins QSK19 PM + load test — $1,800. Generac 750kW controller — $7,200. Kohler 100REOZJ rebuild — $14,000. Annual PM contracts $4,000–$25,000 per site.

## Pain points

- Hospital backup gen fails the monthly load test and you have a 4-hour window to respond — voicemail = lost contract
- Data center wants a load bank rental + scheduled service — booking that requires a human-in-the-loop kills your margin
- After-hours emergency on a hurricane-knocked Cummins QSK60 is the highest-margin work and you're missing the calls
- Quarterly PM contracts need calendar tracking and reminder cadences your spreadsheet doesn't enforce

## Why a booking system matters

Generator service is uptime-critical infrastructure work. A hospital, data center, or assisted-living facility with a failed backup gen is operating in violation of code until it's fixed — and they will pay any vendor who can guarantee a same-day response. The shops with that response capability built into their intake (24/7 missed-call text-back, after-hours dispatch escalation, automated PM reminders) are the ones holding $50K/year service contracts. Everyone else is doing one-off Cummins QSK rebuilds at retail.
The PM cadence is where booking systems earn their keep. A 75-unit commercial portfolio (warehouses, light industrial, healthcare) needs monthly load tests, semi-annual oil services, and annual major PMs. That's hundreds of scheduled visits a year. A spreadsheet calendar drops one in twenty — and one missed PM is the entire reason a 200kW Generac let an Amazon DC down on a Tuesday and cost everyone a contract. Calendar-based PM scheduling with SMS reminders to the customer's facility manager is the entire business.
Tickets are large and recurring. A Cummins QSK19 oil + filter + load test is $1,800. A Generac MPS 750kW controller replacement is $7,200. A Kohler 100REOZJ engine rebuild is $14,000. Annual PM contracts run $4,000–$25,000 per site. One signed contract from a captured inbound lead pays for Defense for a decade.

## Ticket examples

- Cummins QSK19 PM + load test — $1,800
- Generac 750kW controller — $7,200
- Kohler 100REOZJ rebuild — $14,000
- Annual PM contract per site — $4,000–$25,000

## Caller types we capture

- facility managers at hospitals and data centers
- property management companies with portfolio backup gens
- construction GCs with site gens during builds
- homeowners with failed Generac standby units after a storm
