Generac Generators in Mercer Island, WA
Mercer Island is connected to the mainland by I-90 and a 1940 floating bridge, and when a widespread storm knocks out power across King County, island homes are often among the last utility crews can reach. Mauro Electric Inc. is an authorized Generac dealer, and we specialize in installing, maintaining, and repairing standby generators for Mercer Island homeowners and businesses.

Installing a Generator on an Island Power Grid
Mounting the unit and transfer switch, running gas piping and wiring, coordinating with the utility, and securing the required inspections — the install process is thorough everywhere, but on Mercer Island it carries extra weight. With only the I-90 floating bridge connecting the island to the mainland, a downed line or bridge-related outage can leave homes waiting longer than a typical mainland neighborhood for power to come back. We size and install every system so it starts automatically, with no one needing to be home to get it running.
Keeping an Island Generator Ready
A generator that hasn’t been serviced is a real gamble when you’re relying on it precisely because help may be slow to arrive. We check fuel systems, battery charge, air filters, and automatic transfer switch function on a routine schedule for homes throughout East Seattle, near Luther Burbank Park, and across the rest of the island.
Generator Repair, Anywhere on the Island
Error codes, a unit that won’t start, or a transfer switch that isn’t handing off power correctly — our factory-trained technicians diagnose and repair Generac systems across Mercer Island, restoring reliable backup power whether you’re in a waterfront home or up on the hillside.

Sizing for East Channel Homes, Old and New
We don’t size generators off a chart. East Seattle’s older homes near the original East Channel Bridge crossing, waterfront properties, and newer construction further up the hillside all draw different essential-circuit loads, so we calculate each home’s actual needs before recommending a unit.
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.
