  • Generator Won’t Start: Battery failure, fuel supply issues, or electrical faults can prevent your generator from starting. We inspect the entire system to find and resolve the issue.

Frequently Asked Questions About Generator Repair

What is the most common problem with generators?

Battery failure is the most common issue and often prevents the generator from starting. This can be caused by aging batteries, corrosion, or loose connections. Low coolant levels can also cause overheating and automatic shutdown.

Why won’t my standby generator start?

Common causes include battery issues, fuel supply problems, electrical faults, or control system errors. A professional inspection can determine the exact cause.

Can you repair transfer switch issues?

Yes, we repair automatic transfer switches to ensure your generator safely powers your home during outages.

How often should a generator be serviced?

Annual maintenance is recommended to keep your generator reliable and prevent unexpected failures.

When should I replace my generator instead of repairing it?

If your generator is older, frequently breaking down, or facing major component issues, replacement may be more cost-effective.
