Backup power.
Ready when it matters.

EMH Mechanical now provides Cummins whole-home and light commercial standby generator systems. We plan the equipment around the loads you need to keep running, the fuel available at the property and the details required for a clean installation.

More than picking a generator

The system has to match the property.

A standby generator is only useful if it can carry the loads you expect it to carry. Furnace blowers, air conditioners, sump pumps, well pumps, refrigeration and commercial equipment all affect the final system.

We start with what needs to stay powered, then review electrical demand, fuel availability, equipment location, clearances, transfer equipment and the work required to complete the installation. That keeps the proposal realistic and avoids guesswork.

Residential and commercial

Standby power sized around the building.

We do not force every property into the same package. The generator and transfer setup should reflect what actually needs to operate during an outage.

How automatic backup works

Utility power goes out. The standby system takes over.

A standby generator remains outside the building and connects through an automatic transfer system. During an outage, the system detects the loss of utility power, starts the generator and transfers the selected loads. When utility power returns, the transfer equipment moves the building back to the utility and the generator completes its cooldown cycle.

  1. 01
    Outage detected

    The automatic transfer system recognizes the loss of utility power.

  2. 02
    Generator starts

    The standby unit starts automatically without a portable cord or manual setup.

  3. 03
    Loads transfer

    The selected home or business circuits receive generator power.

  4. 04
    Utility restored

    The system transfers back and the generator shuts down after cooldown.

Our process

A clear plan before equipment is ordered.

Generator projects involve more than setting equipment outside. We identify the work, responsibilities and project requirements before installation begins.

  1. 01

    Site & Load Review

    Review the property, electrical service, equipment, fuel supply and loads you want available during an outage.

  2. 02

    System Selection

    Select the generator, transfer equipment and project options around the actual application.

  3. 03

    Project Coordination

    Confirm placement, gas piping, electrical work, permits, access and the installation sequence.

  4. 04

    Installation & Handoff

    Complete the work, startup and operating checks, then review normal operation with the owner.

Cummins standby power

Equipment built for automatic backup.

Cummins QuietConnect standby generators are available with weather-protective, sound-insulated enclosures and options for remote diagnostics, load management and cold-weather operation. The correct model and accessories depend on the building and the loads being served.

Generator questions

What to know before choosing standby power.

What does a standby generator do?+

A permanently installed standby generator monitors utility power. When an outage occurs, the automatic transfer system starts the generator and transfers the selected electrical loads. When utility power returns, the system transfers the building back and shuts the generator down.

Does EMH Mechanical install whole-home generators?+

Yes. EMH Mechanical is a Cummins Onan Generators Authorized Dealer for whole-home and light commercial applications. We handle system planning, equipment selection, placement, gas piping, project coordination and startup for qualifying generator installations.

Can one generator power the entire house?+

Sometimes. The answer depends on the home's electrical service, heating and cooling equipment, well or sump pumps, appliances and the loads you want available during an outage. We review those loads before recommending generator capacity and transfer equipment.

Do Cummins home standby generators run on natural gas or propane?+

Cummins offers residential standby models configured for natural gas or LP fuel. The available fuel supply, meter or tank capacity, piping distance and generator load all need to be reviewed as part of the installation.

Can a standby generator run the furnace or air conditioner?+

It can when the generator and transfer system are sized for those loads. HVAC equipment can have significant starting demand, so we review the actual equipment instead of assuming it will operate from a generator of a certain size.

What light commercial properties can use a standby generator?+

Standby power can be a fit for offices, retail spaces, small shops, apartment common areas and other light commercial buildings. The correct system depends on the building load, fuel, operating priorities and electrical design.

Is electrical work included?+

The final scope depends on the property and project. EMH Mechanical coordinates the generator, transfer equipment, gas piping, electrical work, permits and startup so responsibilities are clear before installation begins.

Where does EMH Mechanical install Cummins generators?+

Our primary generator service territory includes Northern Oakland County, Northern Macomb County, St. Clair County, Genesee County and Lapeer County. Contact us with the project address if the property is near the edge of our normal area.
