Generator Repair
The most common generator issues our electricians repair include the starter, power output, battery, and fuel delivery mechanisms. Backup systems are complex and need professional troubleshooting for reliable repairs. You can trust in Thompson’s quality workmanship to restore functionality quickly.
Generator Replacement
You should replace old generators when they constantly fail or get too expensive to repair. Unlike other home appliances and electrical systems, a generator’s lifespan is in running hours. Most residential models can operate between 1,500 and 3,000 hours. If your backup system dates to 2010, a generator replacement is your best option. Modern systems deliver optimal efficiency, higher capacity, and superior reliability. We invite you to request our expert advice, upfront pricing, and financing options for a system replacement.
Generator Installation
New installations require permits, sizing, placement, and connections. Some projects may need panel or circuit upgrades. Thompson closely adheres to all national, state, and municipal codes when installing backup generators.
Generator Maintenance
Your backup systems are only as reliable as the maintenance they receive. Routine inspections, load testing, and tune-ups are essential for ensuring your generator operates optimally. We can include your generator in the Thompson VIP Club for annual maintenance calls before winter storms arrive.

FAQs
Today’s generators are more affordable and popular than ever before, so customers ask questions about them frequently. Here are the five most common questions customers ask.
How Do I Know What Size Generator My Home Needs?
Our electricians calculate the total watts you need to run essential appliances and systems. We duplicate the starting wattage of the most powerful appliance and add it to the overhead running wattage. Then, we choose models with a capacity that can safely exceed our calculation.
What Are The Signs My Generator Needs Repair?
Loud and strange noises coming from the unit during backup power periods suggest mechanical issues. Smoke and fluid leaks are also common signs. If the ATS mechanism takes progressively longer to activate, there could be engine problems.
How Often Should A Whole-Home Generator Be Serviced?
Schedule service at least once a year, preferably before winter. With a Thompson VIP Club membership, you can include the backup system for professional inspections and tune-ups. Maintenance is the key to preventing generator failures while prolonging equipment lifespan.
Can Thompson Replace An Outdated Generator With A Newer Model?
Yes, this is a common service call we complete in St. George. Modern backup generators use microprocessor logic boards instead of electromechanical systems. They are smart, quiet, and efficient. Depending on the model, we may have to upgrade some circuits and connectors.
How Long Does Generator Installation Take?
Generator installations need municipal permits, which can take a few days to secure. We can perform the calculation and select the system in one day. Our team can complete the wiring and connections in one day, but difficult placement projects may need a few days.
