Generator Installation Guide for Kansas City Homeowners
KC ice storms and tornado seasons make power outages a real threat. Here's everything you need to know about whole-home standby generator installation — sizing, fuel, brands, and cost.
Kansas City sits squarely in a corridor where winter ice storms can knock out power for days, and spring thunderstorms can take down lines overnight. For many KC homeowners, a whole-home standby generator has gone from luxury to necessity.
Here's everything you need to know about getting one installed.
Standby vs Portable: What's the Difference?
Portable generators run on gasoline, require manual setup outdoors, and can power a handful of circuits. They're better than nothing — but they require you to be home, have fuel, and deal with them in the middle of a storm.
Standby generators are permanently installed outside your home, connected to natural gas or propane, and start automatically within seconds of a power outage. No action required from you.
For most KC homeowners, standby is the right choice.
How Big Do You Need?
Generator sizing depends on what you want to power:
- 7–10kW: Essentials — lights, refrigerator, furnace, some outlets
- 14–16kW: Whole home minus central AC (or partial AC)
- 18–22kW: True whole-home coverage including central AC
- 22kW+: Large homes, multiple HVAC systems, pools
We perform a load calculation during the site assessment to size you correctly — undersizing is the most common mistake homeowners make.
Natural Gas vs Propane
Natural gas is the preferred option for homes already on gas service — no fuel storage, no running out, just continuous supply from the utility line.
Propane is the right choice if you don't have natural gas service. You'll need a propane tank sized appropriately for your generator's consumption rate and your local utility schedule.
Brands We Install
- Generac: The #1 selling residential standby brand. Wide dealer network, strong parts availability, good warranty
- Kohler: Premium quality, quieter operation, excellent long-term reliability
- Briggs & Stratton: Good value at the residential level with solid warranty support
- Cummins: Preferred for larger commercial applications
The Automatic Transfer Switch
Every standby generator needs an Automatic Transfer Switch (ATS). This is the device that detects a utility outage, starts the generator, and switches your home to generator power — all within 10 seconds, automatically.
Without an ATS, you'd have to manually connect the generator to your panel during an outage. That's dangerous and code-violating. Every installation we do includes a proper ATS.
What Does Installation Cost?
Standby generator installation costs depend on several key factors:
- Generator size and brand
- Natural gas vs propane (propane requires tank installation)
- Distance from gas line to generator location
- Whether a panel upgrade is needed
- Permit and utility coordination fees
The Best Time to Install
Before you need it. During storm season, lead times grow. The installation process involves utility coordination, permitting, and a site assessment — plan ahead.
