Frequently Asked Questions
Everything you need to know about backup generator systems.
What size generator do I need for my home?
It depends on what you want to power. A 7-10kW generator handles essential circuits (fridge, lights, sump pump). For whole-home coverage including AC, you'll typically need 16-26kW. We perform a load calculation during your free consultation.
How long does installation take?
Most residential installations are completed in one day. Commercial installations vary based on system size and complexity, typically 1-3 days. We handle all permits and inspections.
What fuel does a standby generator use?
Generac standby generators run on natural gas or liquid propane (LP). Natural gas connects to your existing utility line for unlimited fuel. LP requires a tank that we can help you size and coordinate with a fuel supplier.
How quickly does the generator turn on?
Within 10-20 seconds of detecting an outage, your Generac generator automatically starts and begins supplying power through the transfer switch. No manual intervention needed.
What maintenance is required?
Generac generators run a weekly self-test automatically. We recommend annual professional maintenance to check oil, filters, and battery. Stelco offers maintenance plans to keep your system ready year-round.
How much does a generator system cost?
Residential systems typically range from $5,000-$15,000+ installed, depending on size and site requirements. Commercial systems vary widely based on power needs. We provide free, no-obligation estimates with transparent pricing.
Do I need a permit for generator installation?
Yes, generator installations require electrical and sometimes gas permits. Stelco handles all permit applications and coordinates inspections as part of our installation service.
