In Goleta, Santa Barbara Generators handles generator repair for residential, commercial and industrial units of every brand, including systems installed by others and older Onan equipment. Diagnostics and emergency repairs restore failed standby units, and annual maintenance targets stale fuel and dead batteries before an outage reveals them. Commercial emergency systems are exercised monthly and given a documented annual test at rated load, while residential units are serviced every year or every 100 to 200 running hours. Goleta mixes foothill homes exposed to sundowner winds with research and manufacturing businesses along the Hollister Avenue corridor, and as a city incorporated in 2002 it handles its own building permits. For larger facilities, industrial sets are permitted through the air pollution control district and proven with a load bank test, giving repair work on those systems a clear baseline to measure against. Related services include backup generators and industrial generators. Service extends to Isla Vista and Santa Ynez, along with Solvang and the Santa Ynez Valley.
