Trusted Generator Repair and Installation in O’Fallon

Professional generator installation ensures your system is set up safely and efficiently, adhering to local codes and regulations. It typically involves selecting a location that’s accessible for maintenance, away from windows and doors to prevent carbon monoxide poisoning, and ensuring it has an adequate fuel supply. An installer can also teach you about how to safely start and stop the unit, what can and cannot be powered simultaneously, and how to conserve fuel over extended outages.

Like any other appliance, your unit may sometimes require generator repair to operate reliably. A professional will perform a thorough inspection that includes checking oil and coolant levels, testing battery function, and ensuring the fuel system is clean and efficient.

“So happy we chose Potts. Had a good feeling when we met with Montel and were quoted a fair price for moving our service, plus installing a new electrical panel and adding a generator shut off switch. Also, at the time of our quote, we were made aware of a prior unsafe situation created by another electrician (which they fixed, leaving us with a nice, safe, and warm fuzzy feeling when we go to sleep now!) Our Installer, Sean, did a great job. He did the job quickly, and he did a great job (organizing the wires in the new panel and mounting the boxes and additional wires on our siding so nicely). Sean did a great job communicating with us along the way and was very diligent about the quality of his work. Also, we would be remiss if we did not mention that our family life is a little action-packed and hectic, especially with our autistic son around. Sean was so patient and unfazed by all the extra chaos! Thank you for making us feel like a valued customer.”
