WHY SEGUIN NEEDS THIS NOW

WHEN THE GRID FAILS, YOUR Generac Doesn't

The ERCOT grid has proven time and again that Texas homeowners can’t rely on utility power alone. A Generac standby generator activates in seconds — you never even notice the outage.
Why Seguin Needs This Now

Texas Grid Events That Changed Everything

The ERCOT grid has proven time and again that Texas homeowners can’t rely on utility power alone. Seguin and Guadalupe County have experienced extended outages that caused real financial and safety harm. A Generac standby generator isn’t a luxury in South Texas — it’s infrastructure.

2021

Winter Storm Uri
Millions of Texas homes lost power for days in freezing temperatures. Seguin residents experienced some of the longest outages in Guadalupe County. People with generators kept their heat, pipes, and food.

2023

Summer Grid Stress
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 — went dark.
2024+
Storm Season Outages
Severe thunderstorms, hail, and lightning strikes cause regular outages across Guadalupe County. Homes with Generac standby generators never lost power. Homes without them lost refrigerators, A/C, and peace of mind.

Common Questions

Generac Generator FAQS for Seguin Homeowners

How much does a Generac generator cost installed in Seguin, TX?
A Generac home standby generator installed in Seguin typically ranges from $4,500 for an 11kW essential-circuit system to $15,000+ for a fully equipped 26kW whole-home system. We provide a written flat-rate quote after your free on-site assessment — the price you’re quoted is the price you pay.
What size Generac generator do I need for my Seguin home?
Most Seguin homes need between 11kW and 22kW. Because of our South Texas summers, we recommend at least 18kW to ensure your central A/C stays running. As your HVAC and electrical contractor, we calculate your exact load during the free assessment — not a rough estimate.
Do I need a permit for generator installation in Seguin, TX?

Yes. The City of Seguin and Guadalupe County require permits for all standby generator installations. Moorhead Service Company handles all permitting, coordinates with city inspectors, and delivers you a fully documented, permitted installation.

How long does Generac generator installation take?
Most home standby generator installations in Seguin are completed in 1–2 days. This includes generator placement, fuel line connection (natural gas or propane), automatic transfer switch installation, panel integration, and final testing. More complex installs with propane tank setup may take 2–3 days.
Will a Generac generator run my central A/C in Seguin?
Yes — with the right system size. An 18kW or 22kW Generac will power your central A/C. This is critical in Seguin’s summers where extended outages without cooling are a genuine health risk. As your HVAC contractor, we know your exact A/C startup load and size the generator accordingly.
What fuel does a Generac generator use? What if I don't have natural gas?
Generac standby generators run on natural gas or liquid propane. For rural Seguin properties without gas service, we coordinate propane tank sizing, placement, and fuel line installation — everything needed for a complete working system. Many Guadalupe County rural homes use propane successfully.
Does a Generac generator increase home value in Guadalupe County?
Yes significantly. A permitted, professionally installed whole-house generator typically adds $10,000–$15,000 to resale value in the Texas market and is increasingly specified by buyers following the 2021 Winter Storm Uri. We provide written documentation of your installation for your home sale file.
How often does my Generac generator need maintenance?
Generac recommends annual service or after every 200 hours of use. In Seguin’s climate — where generators can run hard during summer heat events — we recommend pre-storm-season maintenance every spring. Moorhead offers annual maintenance plans through our Comfort Club for peace of mind.

“After Winter Storm Uri left us without power for four days, we knew we needed a generator. Moorhead came out, did the assessment free, told us exactly what size we needed for our A/C, and had the Generac installed within two weeks. Passed inspection first try. Worth every penny.”
Tom R.

Seguin, TX — Walnut Springs area

“We had medical equipment that required reliable power. Moorhead didn’t just sell us a generator — they sized it specifically for our needs, set up the Mobile Link app, and walked us through everything. Three storms later, we’ve never lost power once. These guys are genuinely from Seguin and it shows.”
Linda M.

Seguin, TX

“Got quotes from two other companies. Moorhead was the only one that came to the house first, did an actual load calculation, and gave me a flat-rate price in writing. No surprises. The 22kW Generac runs our whole home including the A/C without a hiccup. Life really is better with Moorhead.”
