Annual generator maintenance keeps your backup power ready when storms or outages hit. Morrison Plumbing, Heating, Air & Electrical provides generator maintenance throughout Collinsville and Southern Illinois. We inspect, test, and service standby and portable generators so they start and run when you need them.
We recommend at least one maintenance visit per year. We give you upfront pricing and a clear report of what we did and any recommendations.
Southern Illinois sees severe weather that can cause extended outages. A generator that has not been maintained may not start or may fail under load. Annual service catches small problems before they become failures when you need power most.
Morrison Plumbing, Heating, Air & Electrical serves Collinsville and Southern Illinois. We maintain generators in Belleville, Swansea, Collinsville, Edwardsville, O’Fallon, and surrounding areas.
We also provide generator repair, generator installation, electrical services, and sump pump repair.
Contact Morrison Plumbing, Heating, Air & Electrical to schedule generator maintenance in Collinsville.

Whether you're going electric or protecting everything you own, save $100 on EV charger or whole-home surge protection installation.

Upgrade your electrical panel or add stunning JellyFish permanent outdoor lighting — $250 off either service.
At least once per year. Standby generators that run on natural gas or propane benefit from annual oil changes, filter checks, and load testing.
Cost depends on the type and size of the generator. We provide upfront pricing when you schedule.
