Generator Repair for Mon Valley Storm Season
Pittsburgh doesn’t see the ice storms some regions do, but the hills and heavy tree cover around West Mifflin, Jefferson Hills, and Pleasant Hills mean a strong summer thunderstorm can still bring a limb down on a line and knock out power longer than anyone would like. J&A Heating, Cooling, Plumbing, & Electrical repairs standby and portable generators throughout West Mifflin and the surrounding Mon Valley, whether we installed the unit originally or not.
A generator failing to start is about the worst timing there is, since the moment you need it is usually the middle of a Duquesne Light outage.

Common Generator Problems We Repair
- It won’t start when utility power drops
- It runs, but the house never gets power
- There’s a fault or error code on the control panel
- The battery won’t hold a charge or the unit won’t crank
- It starts but runs rough or shuts down once it’s under load
- The automatic transfer switch doesn’t sense the outage
Our Diagnostic Process
We pull any fault codes from the control panel and check battery voltage first, since a weak starting battery is the single most common reason a standby generator fails to crank during an outage. From there we test the transfer switch, fuel supply, and charging system before moving into engine-specific diagnostics. If the transfer switch needs more capacity than your panel can provide, we’ll flag that as part of a panel upgrade. Because most generator failures trace back to a maintenance gap rather than a single broken part, we’ll flag anything that points to that so you can decide whether an ongoing service plan makes sense.
Keeping It From Happening Again
Most of the generator repair calls we run could have been caught earlier with routine maintenance. We recommend regular visual checks, periodic load testing, and a full annual service covering oil, filters, and the transfer switch. If your unit has already failed once, we’ll build a maintenance schedule around it during the repair visit.
