Why Backup Power Matters in Iowa
Iowa’s unpredictable weather — from summer storms to winter ice — means power outages are more than a nuisance. For many Iowa homeowners, especially those in rural areas, backup generators are becoming essential. Whether it’s to keep sump pumps running during heavy rains or to preserve warmth in freezing temperatures, having a standby generator ensures safety, comfort, and peace of mind.
Types of Home Backup Generators
1. Portable Generators
- Typically powered by gasoline
- Best for temporary, selective use (e.g., refrigerator, lights)
- Require manual setup and fueling
2. Standby (Whole-Home) Generators
- Permanently installed outside the home
- Automatically turn on during outages
- Run on natural gas or propane
- Can power the entire home, including HVAC systems
For Iowa homes where outages are longer or more frequent, standby generators are the preferred choice due to convenience and capacity.
Sizing the Right Generator for Your Home
Choosing the right size generator is crucial for both performance and safety. Factors include:
- Total wattage needed (HVAC, appliances, lighting)
- Home size and layout
- Fuel source availability (natural gas or propane)
A licensed electrician will perform a load calculation to recommend the correct size, typically ranging from 14kW to 22kW for most Iowa residences.
Installation Considerations
1. Permitting and Code Compliance
Iowa municipalities often require electrical permits for standby generator installation. Working with a licensed, local electrician ensures compliance with the National Electrical Code (NEC) and city regulations.
2. Transfer Switch Integration
A critical part of installation is the automatic transfer switch (ATS), which seamlessly switches power from the grid to the generator during an outage and back when service resumes.
3. Proper Site Selection
Generators must be placed with consideration to:
- Minimum clearances from windows and doors
- Sound levels
- Flood-prone areas
- Access for service and refueling
Regular Maintenance Is Non-Negotiable
Just like a furnace or water heater, backup generators require regular care to function properly during emergencies. Coffin Electric recommends:
- Monthly visual checks (fluid levels, corrosion, debris)
- Bi-annual professional inspections
- Annual oil and filter changes
- Load testing to ensure full performance capacity
Consider enrolling in a generator maintenance plan to ensure peak readiness when it matters most.
Seasonal Readiness in Iowa
Backup power becomes top of mind during:
- Spring and summer storms (tornadoes, lightning, high winds)
- Fall generator tune-ups before winter
- Winter outages tied to ice and snow accumulation
It’s best to schedule installations in spring or early summer — before demand spikes during storm season.
