Generac Generator Installation
As a certified Generac installer, we handle standby generator installations throughout Mercer Island — coordinating with the utility company, mounting the unit and transfer switch, running gas piping and wiring, and securing the required inspections. Given how much slower utility crews can reach an island property during a widespread outage, we make sure every system is set up to run reliably and automatically without anyone needing to be there to start it.
Generac Generator Maintenance
Routine maintenance keeps your Generac generator ready to perform when the power actually goes out, which matters more on Mercer Island given the added time it can take for crews to reach the island during a bigger outage. We inspect and service standby generators throughout the island, checking fuel systems, battery charge, air filters, and automatic transfer switch function on every visit.
Generac Generator Repair
If your Generac generator is throwing an error code, failing to start, or not transferring power correctly, our factory-trained technicians can diagnose and repair it. We work on Generac systems throughout Mercer Island, restoring your backup power quickly rather than leaving you waiting on utility crews.

Standby Power for an Island Community
Being connected to the mainland by I-90 means Mercer Island can see slower utility response during a widespread outage compared to areas with more direct crew access, which makes a standby generator more valuable here than in many neighboring cities. Waterfront homes and hillside properties both benefit from a system that switches on automatically, so you’re not without power — or without your well pump, sump pump, or medical equipment — during a longer restoration.
Most Generac systems run on natural gas or propane, and we help you weigh which fuel source makes sense based on what’s already available at your property.
