# Generator Maintenance & Service Plans | Dallas-Fort Worth **URL:** https://utselectricpros.com/maintenance **Summary:** Standby generator maintenance in DFW: what a service visit covers, how often it is needed, and why skipped maintenance causes outage failures. **Overview:** A standby generator spends almost all of its life switched off, which is exactly what makes it fail: batteries die quietly and fuel goes stale with nothing to signal it until the night the power goes out. Maintenance is not upkeep on something in use; it is the only thing that proves the machine still works. The two causes of a no-start during an outage are consistently the battery and the fuel, and both are found by a routine visit: a battery that measures fine at rest can still collapse under crank load, and fuel that has sat a year is not the substance that went in. There is also a contractual reason, since manufacturers generally require documented service to honor a warranty claim.

That is exactly what makes it fail: batteries die quietly, fuel goes stale, and nothing tells you until the night the power goes out. Maintenance is not upkeep on something you use — it is the only thing that proves the machine still works. Cummins manufacturer photography. ## Why it matters more than owners expect Ask any generator technician what causes a no-start during an outage and you will hear the same two answers: the battery and the fuel . Neither is exotic, and both are found by a routine visit. A battery that measures fine sitting still can still collapse under crank load. Gasoline and diesel that have sat for a year are not the same substances that went in. The second reason is contractual rather than mechanical. Manufacturers generally require documented service to honor a warranty claim. A homeowner who skipped maintenance for three years and then has a major component fail is often holding an expensive repair that would otherwise have been covered. The weekly exercise cycle is not maintenance. It keeps seals lubricated and confirms the unit starts, which is worth having — but it changes no oil, tests no battery under load, and verifies no transfer switch. It is a self-check. ## What a service visit actually covers Parts used are genuine Cummins — [see part numbers](https://utselectricpros.com/accessories). Not every item applies to every unit — spark plugs are a gas concern, coolant is a liquid-cooled one. This is the full scope we work from. - **Oil and filter change:** The single most important item. Standby engines run under load from cold starts, which is hard on oil. - **Air filter:** Inspected every visit, replaced on interval or sooner in dusty rural installs. - **Spark plugs:** Gas units. Fouled plugs are a common no-start cause after long idle periods. - **Battery test and terminals:** The number one cause of a generator not starting. A battery that reads fine at rest can still fail under crank load, so it is tested under load, not just measured. - **Coolant and hoses:** Liquid-cooled units. Level, condition, and any weeping at connections. - **Fuel system:** Gas pressure under load, or on diesel a fuel condition and water check. Diesel that has sat can grow biological contamination. - **Transfer switch operation:** A live transfer test. The generator starting is only half the system working. - **Load test:** Run under actual load, not at idle. An unloaded run proves almost nothing. - **Controller and fault log:** Any stored codes read and cleared, exercise schedule confirmed. - **Written report:** What was done, what was found, what to watch. That record is what a warranty claim needs. ## Commercial and life-safety systems are different If your generator serves emergency lighting, fire pumps, egress systems or anything else classified as a life-safety load, it is not governed by manufacturer guidance alone. Those systems fall under NFPA 110 , which sets its own testing regime — routine operational testing at defined intervals, and periodic testing under real load, with records kept. Building owners are frequently unaware of this until an inspection or an insurance review raises it. If you operate a clinic, a restaurant, a multi-tenant building or a facility with emergency egress lighting on generator backup, the compliance obligation is yours whether or not anyone has mentioned it. We handle commercial standby maintenance and the documentation that goes with it. If you are not sure which category your system falls into, that is a short conversation and worth having before someone else raises it for you.

Broadly, an annual service plus an oil change on a run-hours basis, with the exact interval set by the manufacturer for your model and by how much the unit actually runs. A generator that only exercises weekly reaches the calendar interval long before the hours interval. One that ran for four days during an ice storm may need service immediately afterwards regardless of when it was last done. We set the interval at handover and tell you what triggers an early visit. ### What actually happens if I skip maintenance? Two things, and the second is worse than the first. You risk voiding warranty coverage, because manufacturers generally require documented service for a claim. And you materially increase the chance the unit does not start during the outage you bought it for. Dead batteries and stale fuel are the leading causes of standby generator no-starts, and both are exactly what a service visit catches. A generator that fails on the one night it was needed has delivered zero of the value you paid for. ### Do you service generators you did not install? Yes, after we inspect the existing installation first. We need to see how it was put in before taking responsibility for how it runs. If we find something genuinely unsafe we will tell you plainly and quote the fix separately — we will not quietly take on a maintenance contract for a system we would not have installed. ### Do you service other brands, or only Cummins? We are a licensed electrical contractor, so we can perform electrical work and general maintenance on other brands. Warranty work on another manufacturer has to go through that manufacturer's dealer network. If you have an out-of-warranty unit of another brand, call and we will tell you honestly whether we are the right people for it. ### Is the weekly exercise cycle enough on its own? No. The exercise cycle keeps seals lubricated and confirms the unit will start, which is genuinely valuable, but it does not change oil, test the battery under load, check gas pressure under demand, or verify the transfer switch. It is a self-check, not a service. ### What does maintenance cost? It depends on the unit and the interval, so we quote it against your specific model and installation. What we will not do is perform work you have not approved beforehand — anything found during a visit gets quoted before it gets fixed. ## Get on a schedule Whether we installed it or not. Tell us the make, the model and roughly when it was last serviced, and we will tell you what it needs.
