Frequently Asked Questions — Generator Service & Repair

How often should I service my standby generator in CT?

Generac and Kohler recommend annual service for most standby generators. In Connecticut, where storm season runs nearly year-round, we recommend scheduling service each spring before peak outage season.

My generator won't start — what should I do?

Call TJF Electric at (860) 847-8047. Tyler is available 24/7 for emergency generator repair across Willington, Tolland County, and Eastern CT. Common causes include dead batteries, low oil shutoff, or stale fuel — most are fixed same-day.

Do you service all generator brands?

Yes — TJF Electric services Generac, Kohler, Briggs & Stratton, Cummins, Champion, and all other standby and portable generator brands. You do not need to have bought your generator from us.

How much does generator maintenance cost in Connecticut?

Annual generator maintenance in CT typically runs $150–$350 depending on generator size and what needs replacement (oil, filters, spark plugs, battery). TJF Electric provides upfront pricing before any work begins.

Google Reviews

TJF Electric did an excellent job upgrading our electrical service from 100 amp to 200 amp, along with several other necessary upgrades. They were professional, on time, easy to work with, and communicated clearly throughout the entire process. The work was completed efficiently and everything was done neatly and correctly. We are very happy with the results and would highly recommend TJF Electric to anyone looking for reliable and professional electrical work. We are looking forward to using them for our upcoming generator project.Read more
