A generator that hasn't run since spring is a generator you can't count on. Alaska's cold and our long shoulder-season outages mean standby units need annual attention to be trustworthy when the wind takes the power out.
Annual maintenance
Oil and filter, fuel filter, air filter, spark plugs on a schedule. We bring the manufacturer's service kit and document the visit so your warranty stays intact. While we're there, we read the battery state of health — the #1 cause of no-start in cold weather.
Fuel storage
Diesel and propane behave differently in the cold. Diesel needs winterizing additive and a fuel polishing schedule if the tank sits more than a year. Propane tank pressure drops below -20°F — sizing the tank and regulator for our climate is part of a proper Alaska generator install.
Transfer switch test
Every six months, kill utility power at the main and watch the generator pick up the load. If the transfer takes more than 10 seconds or any circuit doesn't come back, that's the maintenance call to make before October.
