Huntsville Generator FAQs

How do I know what size generator I need for my home?

Generator sizing depends on your home’s electrical load, including HVAC systems, major appliances, and whether your home is all-electric or gas-assisted. Factors such as AC tonnage, well pumps, and simultaneous power usage all affect sizing. Valley Services performs professional load calculations to ensure your generator is properly sized for reliable, safe operation.

Do you install whole-home standby generators or portable generators?

We specialize in permanently installed standby generators designed to power critical systems or your entire home automatically during an outage. These systems are connected directly to your electrical panel and fueled by natural gas or propane for long-term reliability.

How long does generator installation take?

Most residential standby generator installations are completed within 1–2 days, depending on electrical upgrades, gas connections, permitting, and site conditions. Valley Services handles the full installation process, including coordination with inspections and utility requirements.

Do I need a transfer switch with my generator?

Yes. A transfer switch is required to safely connect a generator to your home’s electrical system. It automatically shifts power from the utility to the generator during an outage and back once power is restored. All standby generators installed by Valley Services include a properly sized and code-compliant transfer switch.

How often does a standby generator need maintenance?

Standby generators should be serviced at least once per year. Routine maintenance includes oil and filter changes, battery testing, system diagnostics, and operational checks. Regular service helps prevent failures and extends the life of your generator.

Can a generator power my air conditioner?

Yes, but generator size is critical. HVAC systems have high startup loads, especially heat pumps and electric heat strips. Valley Services evaluates your HVAC system and electrical demand to ensure your generator can start and run your air conditioning safely without overload.

What fuel types do standby generators use?

Most standby generators operate on natural gas or propane. Natural gas provides continuous fuel where available, while propane is a reliable option for homes without gas service. We help determine the best fuel choice based on availability and runtime needs.

How long will a standby generator run during a power outage?

As long as fuel is available, a standby generator can run continuously for days or weeks during an extended outage. Natural gas systems offer the longest uninterrupted runtime, while propane systems depend on tank size and consumption.

Are permits required for generator installation?

Yes. Generator installations typically require electrical and sometimes gas permits, along with local inspections. Valley Services manages the permitting process to ensure all work meets local codes and safety standards.

Do you provide generator repair services?

Yes. We service and repair most major standby generator brands. Whether your generator won’t start, shows fault codes, or needs electrical or fuel-related repairs, our technicians can diagnose and restore proper operation.

How long do standby generators typically last?

With proper maintenance, a quality standby generator can last 15–25 years. Regular service, clean fuel supply, and proper installation are key factors in long-term reliability.

What happens if my generator doesn’t start during an outage?

Modern standby generators perform automatic self-tests to reduce startup issues, but failures can still occur due to battery problems, maintenance neglect, or component wear. Routine maintenance significantly reduces the risk of startup failure when you need power most.

Do you offer generator service plans?

Yes. Valley Services offers maintenance plans designed to keep your generator ready year-round. These plans help prevent unexpected breakdowns and ensure your system operates correctly during outages.

Can you service generators outside your immediate city?

Yes. While each city page highlights a primary service area, we regularly service generators throughout North Alabama and Southern Tennessee. If you’re unsure whether your location is covered, contact us directly.
