Power outages can happen without warning—but your home doesn’t have to be left in the dark. A standby generator provides automatic, reliable backup power when the grid goes down, keeping essential systems running safely and smoothly. At D'Spain Sales & Service, we provide professional standby generator services in Bandera, TX, and the surrounding Hill Country region, including installation, repair, maintenance, and replacement.
As a trusted, family-owned company, we help homeowners prepare for outages caused by severe weather, grid issues, and unexpected utility disruptions. With experienced technicians and dependable equipment, D’Spain ensures your generator is ready when it matters most.
How Does a Standby Generator Work?
A standby generator, or whole-home generator, is a permanently installed backup power system that automatically activates when a power outage occurs. Connected directly to your home’s electrical system and powered by natural gas or propane, it restores power within seconds—without any manual setup.
Standby generators can supply power to:
- Heating and cooling systems
- Refrigeration and food storage
- Medical and mobility equipment
- Lighting and outlets
- Security and safety systems
- Well pumps and critical appliances
Once utility power is restored, the generator shuts off automatically and returns to standby mode.

Standby Generator Installation
A standby generator is only as reliable as its installation. Proper sizing, placement, and connection are critical to ensuring safe operation, consistent performance, and long-term dependability. At D'Spain Sales & Service, our experienced technicians take a detailed, whole-home approach to generator installation—so your system performs exactly as it should when power is lost.
We begin by evaluating your home’s electrical demands, identifying which systems and appliances you want powered during an outage.

Standby Generator Repair Services
When your standby generator isn’t working properly, your home is left vulnerable during power outages. Whether your system fails to start, operates inconsistently, or displays warning indicators, prompt professional repair is essential to restore safe and dependable backup power.
At D'Spain Sales & Service, our experienced technicians are equipped to diagnose generator problems and deliver reliable, long-lasting repairs quickly.
Standby generators are complex systems that integrate electrical components, fuel delivery, sensors, and control panels. Even minor issues can prevent your generator from operating when it’s needed most. Our team uses advanced diagnostic tools and manufacturer-approved procedures to identify the root cause—not just the symptom—of the problem.
Signs Your Standby Generator Needs Repair
Common signs your standby generator may need professional repair include:
- Failure to start during a power outage: Often caused by electrical, fuel, or control system issues.
- Warning lights or error messages: System alerts indicate performance or safety concerns that should be addressed immediately.
- Unusual noises or excessive vibration: May signal mechanical wear, loose components, or internal damage.
- Inconsistent or partial power output: Can result from load issues, electrical faults, or generator capacity problems.
- Failed self-tests or system alerts: Indicates the generator is not prepared to operate reliably during an outage.
Addressing generator issues early helps prevent larger failures, costly repairs, and unexpected downtime. With D’Spain, you can trust that your standby generator will be repaired correctly—so when the power goes out, you can trust your backup power is ready.

At D'Spain Sales & Service, our professional maintenance services are designed to prevent unexpected failures, extend the lifespan of your generator, and ensure your system is always ready to respond during emergencies. Our technicians follow manufacturer-recommended service procedures and thoroughly inspect every critical component of your system.
