FAQs

Frequently asked questions

Still have questions?

How often should I change the oil in my standby generator?

Generac standby generator oil should be changed during regular maintenance—typically once or twice per year based on runtime and the manufacturer’s schedule. The need most often comes from extended outage run time and frequent cold starts, which break oil down faster than light exercise cycles. During our visit we change oil and filters, perform a load test, and document results to help protect your manufacturer warranty. One field pattern we see is that units with few outages still age their oil from moisture and short self-tests, so timing matters even when the generator seldom runs. We routinely maintain Generac systems for homeowners in the Franklin area.

Service sooner if you notice:

  • A maintenance reminder or fault on the control panel
  • Many consecutive hours of operation after a recent outage
  • Dark/gritty oil on the dipstick or a dropping oil level

Shut the unit down and call a licensed technician if you see leaks, low‑oil shutdowns, or any warning lights.

How much does whole house generator installation typically cost?

Whole-house generator installation costs vary by home, and we confirm pricing after an on-site load assessment and design. Factors that drive price include:

  • Generator size (kW) and coverage (whole-home vs. critical circuits).
  • Fuel type (natural gas or propane) and gas line work.
  • Transfer switch type and installation location. We install systems in Quincy and Newton. We are a certified Generac dealer. Financing is available. We also offer a free estimate for Generac whole-house installations.

How much does standby generator repair typically cost?

Standby generator repair with Castle Electric Inc. is priced after a certified diagnostic because total cost varies by fault, needed parts, and labor time. Most repairs stem from failed components or fuel delivery issues rather than simple settings. We are Generac-certified and service Generac units only, using genuine parts and factory-approved procedures. Our technicians routinely support homeowners in the Ashland area when storms expose weak batteries, sensors, or fuel pressure. Emergency help is available 24/7, and financing options are available for larger repairs. A quick voltage and fuel-pressure check often narrows the issue fast.

Common repairs that drive pricing and next steps:

  • Transfer switch or start circuit faults (adjustment vs. component replacement)
  • Fuel supply or pressure fixes (regulators, leaks, clogged lines)
  • Wiring or connection remediation (loose lugs, corrosion)
  • Control panel or sensor failures (board replacement and programming)

If you smell gas, hear arcing, or see persistent alarms, shut the unit down and schedule a certified diagnostic before running it again.
