Generator Repairs that Fix the Problem,
Not the Symptom.
Critical downtime is too costly to spend time searching for “industrial generator repair near me” or “commercial generator repair service near me.” Instead, call Power Plus first to get the professional, expert generator repairing service you need.<br><br>Our comprehensive care plan goes beyond a basic generator maintenance schedule. We troubleshoot the root cause, rebuild if necessary, and source what others can’t. So your generator runs smoothly every time – not just until the next test or regular inspection – and keeps running for the long haul. Our commercial generator repair services cover every critical component:
-
Engine Repairs & Rebuilds
When others tell you to replace your old engine, we often disagree. We regularly diagnose and fix issues others can’t or won’t.
-
Electrical Systems & Alternator Rewinds
Addressing generator electrical systems, ECMs (engine control modules), and generator control panel issues – as well as repairing/rewinding alternators – restores steady output for your electrical load.
-
Fuel Systems & Fuel Tanks
Everything from fuel polishing to addressing leaky fuel lines and ensuring compliance issues.
-
Radiators & Cooling Systems
Ensuring nothing overheats and takes your generator down.
-
Building Management Systems & Generator Control Upgrades
Maintaining the control systems behind your backup power.
We’d Rather Fix Your Generator
than Sell You a New One.
Call us old fashioned, but Power Plus thinks that fixing your existing generator – no matter how challenging the problem – is the smartest way to save you money. But these days, you won’t hear that from a lot of other generator companies. Instead of dedicating their time, energy, and patience to ensure your generator meets your power requirements, many of them work to upsell you to a more expensive new unit.
