Why Seguin Needs Backup Power Now
Winter Storm Uri — 2021
Millions of Texas homes lost power for days in freezing temperatures. Seguin and Guadalupe County experienced some of the longest outages in the state. People with generators kept their heat, pipes, and food. People without them lost all three.
Summer Grid Stress — 2023
ERCOT issued emergency alerts as South Texas heat pushed record demand. Homes without backup power faced dangerous indoor temperatures. Central A/C — a health necessity in Seguin summers, not a comfort — went dark.
Every Storm Season Since
Severe thunderstorms, hail, and lightning cause regular outages across Guadalupe County. Homes with Generac standby generators never lost power. The pattern doesn't change. The risk doesn't either.
A Generac standby generator isn't a luxury in South Texas. It's infrastructure. Portable generators are dangerous when people run them in garages — Justin installed CO detectors across Seguin after Uri where families had been venting generators into closed structures. A standby generator is outside, permanent, and connected to your natural gas or propane. No fuel to store, no startup hassle, no CO risk.
Which Generac Do You Need?
We perform a free load calculation during your on-site assessment. Here's a guide sized for South Texas homes with central A/C.
| Model | Output | Best For | What It Powers |
|---|
| Guardian 11kW | 11 kW | Small homes under 1,500 sq ft | Essential circuits: lights, fridge, window A/C, well pump |
| Guardian 18kW ★ Most Popular | 18 kW | 1,500–3,000 sq ft — the Seguin standard | Whole home including central A/C, all appliances simultaneously |
| Guardian 22kW | 22 kW | 2,500–4,000 sq ft or dual-zone A/C | All appliances, workshop, pool equipment, EV Level 1 |
| Guardian 26kW | 26 kW | 4,000+ sq ft, medical equipment, home business | Multiple A/C systems, EV charger, full estate |
What Moorhead Installs
Generator Installation
Complete turnkey Generac installation in Seguin — load analysis, site prep, permit filing with the City of Seguin or Guadalupe County, transfer switch, natural gas or propane fuel line connection, and full startup test. We handle everything.
- Free on-site load analysis
- Permit filing — City of Seguin / Guadalupe County
- Generator placement and site prep

Annual Maintenance
Generac recommends annual service or every 200 hours. In Seguin's climate, pre-storm-season maintenance every spring means your system is ready when it counts — not being diagnosed during an active outage.

- Battery load test
- Transfer switch exercise and test
- Air filter inspection

Generator Repair
Error codes, fails to start, runs rough — we diagnose and repair all issues with genuine Generac parts from factory-trained technicians. Your warranty stays intact.
Automatic Transfer Switch Installation
Already have a generator without an ATS? We install Generac's automatic transfer switches — the component that makes your generator respond within seconds of an outage, without you touching anything.
Propane Setup for Rural Seguin
Many rural Guadalupe County properties don't have natural gas. We coordinate propane tank sizing, placement, and fuel line installation so you're never without a fuel source — including coordination with Guadalupe Valley Electric for permit requirements.
The One Thing Other Installers Miss
Moorhead is both a licensed HVAC contractor and an authorized Generac dealer. Central air conditioning is the single biggest draw on a home generator. Getting that calculation wrong means your generator shuts down on the hottest day of the year — which is also the day of the longest outage. Other installers estimate your A/C load. We know it precisely because we installed it.
How It Works
- Free on-site assessment — Load calculation, fuel source assessment, panel evaluation, and Generac model recommendation. No pressure, no obligation.
- Flat-rate written quote — One number, on the spot, covering everything. The price you're quoted is the price you pay.
- Permits pulled — We handle all permitting and coordinate with city inspectors and Guadalupe Valley Electric.
- Installation (1–2 days) — Generator placement, fuel line, transfer switch, panel integration, final testing. Most Seguin installs complete in 1–2 days.
- Test and handoff — Full load test, city inspection coordination, Mobile Link app setup, owner walkthrough. You leave knowing exactly how your system works.
Home Value
A permitted Generac whole-house generator typically adds $10,000–$15,000 to resale value in Guadalupe County and is increasingly requested by home buyers after the Texas grid events. We provide all documentation for your home sale file.
