Annual Maintenance

Service, Repair & Installation

The importance of proper generator maintenance cannot be stressed enough, New England weather, poor reliability of utility power and quite often safety, requires your generator system and transfer switch to be in top shape year round.

Through use and over time, batteries, oils, fluids, spark plugs, belts and hoses begin to deteriorate, valve clearance, ignition timing and frequency need to be adjusted; regular maintenance is the only way to ensure that your standby or portable generator system will perform when your lights go out.
