An outage is the worst time to find out

Most standby generators fail for small reasons a maintenance visit would have caught: a weak battery, old fuel, a worn belt or a transfer switch that sticks.

When the utility drops, that small issue becomes closed doors, spoiled inventory, lost data and tenants calling your property manager. In Central Florida, hurricane season raises the stakes every year.

Commercial generator maintenance turns that risk into a schedule: inspections, exercise runs and testing on a calendar, with a report after every visit so you always know the condition of your equipment.

Why commercial generators fail

Five problems cause most standby generator failures, and all of them show up on a maintenance checklist first.

Weak batteries

Risk: the generator won't start

The most common reason a standby generator fails to start.

How we fix it: tested on every visit

Old or dirty fuel

Risk: shutdown mid-outage

Diesel that sits for months collects water and sludge.

How we fix it: annual fuel testing

Coolant and belts

Risk: overheating under load

Leaks and worn belts show up when the engine works hard.

How we fix it: checked every visit

Transfer switch faults

Risk: the building stays dark

A running generator is useless if the ATS does not transfer.

How we fix it: ATS inspection and testing

Never tested under load

Risk: it can't carry the building

Running without load proves the engine starts, not that it can power your building.

How we fix it: load bank testing

Frequently asked questions

How often should a commercial generator be serviced?

It depends on how critical your operation is. Mission-critical sites usually need monthly service, while most commercial buildings are well covered with quarterly or annual programs. We recommend a schedule after reviewing your system.

What does commercial generator maintenance include?

Inspections, exercise runs, battery and charger checks, transfer switch inspections, fuel quality testing, load bank testing when needed, and a written service report after every visit.

Do you service generators from different brands?

Yes. We are an authorized Kohler, Generac and Cummins dealer and service most other major generator brands, as well as Thomson transfer switches.

What is load bank testing and do we need it?

A load bank applies real electrical load so we can confirm the generator delivers its rated power. It is recommended when routine runs happen at light load, which is common in commercial buildings, and it burns off the carbon buildup known as wet stacking.

Can you take over from our current provider?

Yes. We start with an inspection of your generator and service history, then pick up the schedule without gaps.

Do you offer temporary power during repairs?

Yes. We provide rental generators to keep your business running while your equipment is repaired or replaced.

How much does a maintenance agreement cost?

It depends on the size of the generator, the number of transfer switches and how often your operation needs service. We inspect your system and send a written proposal.

What areas do you serve?

We serve businesses across Central Florida, including Orange, Seminole, Lake and Osceola counties.
