Whole Home Generator Reviews from St Louis Customers

⭐⭐⭐⭐⭐

“We lost power for three days during the ice storm last winter, but our house stayed warm and comfortable thanks to the Generac generator Bates installed. The electricians were professional from start to finish, handled all the permits and fuel line work, and even showed us how to use the monitoring app. Worth every penny for the peace of mind.”

“Bates Electric did an excellent job on our standby generator project. They helped us choose the right size Guardian Series unit, coordinated everything with Ameren and Spire, and completed the work in two days. Our neighborhood has frequent storm-related power outages, and now we don’t even worry about it anymore. The generator kicks on automatically and we barely notice.”

Common Generator Questions in St Louis

What size whole home generator do I need for my St Louis home?

Generator sizing depends on your home’s electrical service and what you want to power when you lose power. Most St Louis homes need between 13kW and 26kW. A 13-16kW Generac Guardian Series generator can power essential circuits including refrigerators, heating/cooling, well pumps, and some lighting. A 20-24kW unit can run most of your home including multiple AC units and major appliances. We perform detailed load calculations during our free consultation to recommend the right size for your specific needs and budget.

How long does generator installation take in St Louis?

Most standby generator projects take 1-2 days for the physical work. However, the complete process from consultation to final inspection typically takes 2-4 weeks. This includes the initial site assessment, permitting with your local municipality, coordinating with Ameren Missouri and Spire if needed, the actual setup, and final inspection. We handle all the paperwork and scheduling to make the process as smooth as possible for you.

Do you only install Generac generators or other brands too?

We’re an authorized Generac dealer and exclusively install Generac generators. We focus on one brand because it allows our electricians to develop deep expertise with these systems. Generac is America’s #1 selling generator brand with the best warranty coverage and service network. By specializing, we can offer better installation quality, faster generator repair service, and more knowledgeable support than shops that work with multiple brands.

How much does a whole home generator cost in St Louis?

Complete backup generator installations typically range from $8,000 to $18,000 depending on the generator size, your home’s electrical configuration, whether fuel lines need to be extended, and permit requirements. This includes the Generac generator unit, automatic transfer switch, all electrical work, connection work, concrete pad, permits, and setup labor. We offer free virtual quotes and financing options to make emergency backup power affordable. The investment protects your appliances, prevents food spoilage, stops frozen pipes, maintains sump pump operation, and keeps heating or cooling running during extended power outages.

What maintenance does a Generac whole home generator need?

Generac recommends annual maintenance for optimal performance. This includes changing the oil and filter, inspecting the battery, checking the coolant level, testing the automatic transfer switch, running load bank tests, and updating controller firmware if needed. Most St Louis homeowners schedule service in spring or fall. Regular maintenance ensures your generator starts reliably when you lose power and extends the system’s lifespan. We offer annual service plans and can send reminders when your generator is due for maintenance.

What fuel options are available for Generac generators?

Generac offers natural gas, propane, and diesel generator options. For residential applications in St Louis, we primarily install natural gas and propane models. Natural gas generators connect directly to your existing utility line, providing unlimited fuel supply. Propane models work well for homes without natural gas service and use an on-site tank. Both options provide automatic emergency backup power without refueling concerns during extended power outages.

Can I install a generator myself or do I need a licensed electrician?

In Missouri, backup generator setup requires a licensed electrical contractor. The work involves connecting to your main electrical panel, installing an automatic transfer switch, running fuel lines, and pulling building permits. These aren’t DIY projects. Improper installation can create serious safety hazards including electrocution, fuel leaks, carbon monoxide poisoning, or fires. Additionally, you’ll void your Generac warranty without professional installation. Our licensed electricians ensure everything is installed safely, to code, and with proper permits and inspections.
