Whole-Home Generator FAQ

This depends on what you want to power when the electricity goes out. Some people just want the basics, like the fridge, sump pump, and a few lights, while others want the entire house to run like normal. An A.B. May technician can help you determine your must-haves and match you with the right size generator.

When the power goes out, a whole-home generator turns on automatically to keep things running. It uses a transfer switch to flip from utility to generator power. No scrambling in the dark or dragging out a portable unit — the generator just starts up and does its job.

If it’s hooked up to a natural gas line, a generator can run continuously for days. If it runs on propane or diesel, the size of your tank and backup fuel supply set the limit.

Most run on natural gas or liquid propane, though some models also use diesel. Natural gas is the most common fuel in cities because it’s usually available from a built-in utility line. Propane might be a better fit in a more rural setting since it’s easy to store on-site.

Annual maintenance is usually enough to keep your generator running for the next 20 to 30 years. Some units also run a weekly self-check to make sure everything is good to go.

Whole-home generators appeal to buyers in areas prone to storms or frequent outages. The upgrade shows potential buyers you were thinking ahead and makes your home stand out from others on the market.

DIY installation isn’t a good idea unless you’re licensed for electrical and gas work. These systems must safely tie into your home’s power and fuel sources, so you want someone who knows what they’re doing. Kansas City also requires a permit to install a generator.

A.B. May can install your generator right the first time and take care of all the paperwork.

Generac is among the most trusted names in home backup power. This brand offers many options, from basic setups to whole-house solutions. The reliability is great, the technology is solid, and support is easy to find.

The process varies by model, but the general steps include turning off the generator, clearing any error messages, and switching it back to auto. This returns it to standby mode, so it’s ready for the next outage. Check the user manual for your model’s exact steps.

Look at the control panel for the generator’s current status, or download the Mobile Link app to check from your phone. You’ll be able to see if it’s running, has an error, or needs maintenance.

Most Generac generators can be combined with solar setups to create a solid backup power system. Talk to an installer to ensure that the inverters, battery storage, and other components work well together.
