Generator Maintenance in Miami, FL

Q: How big of a generator do I actually need to power my house during an outage?

Don't try to power everything — focus on essentials. A 7,500W generator handles refrigerator, lights, sump pump, and window AC or fans. A 14,000W+ unit or whole-home standby can run central HVAC. Key appliances to calculate: central AC (3,500–5,000W startup surge), well pump (1,500–3,000W), refrigerator (800W). An electrician can calculate your specific load requirements.

Q: I was quoted $12,000 for a whole-home standby generator. Is that typical?

Yes — a 20kW Generac or Kohler standby generator with automatic transfer switch and natural gas or propane hookup typically runs $8,000–$15,000 installed. Variables: generator size, transfer switch type (whole-home vs. essential circuits), fuel type, and run time to existing gas line or propane tank. The 10–20kW range covers most homes.

Q: My standby generator runs on natural gas. What happens if the gas goes out in a disaster?

This is the main vulnerability of natural gas standby generators. Natural gas service can be interrupted during earthquakes, major infrastructure events, or utility maintenance. If backup power during gas outages is a concern, a dual-fuel generator (gas + propane with a tank) or a battery+solar backup system provides redundancy.

Q: Do I need a permit to install a whole-home standby generator?

Yes — always. Generator installation requires electrical permits (for the transfer switch), and usually a gas permit (for the fuel line). Permitted installations ensure the transfer switch is properly wired to prevent backfeed (which can electrocute utility workers). Never use a portable generator indoors or in a garage — CO poisoning is a leading cause of generator-related deaths.

Q: How often should a standby generator be serviced?

Annual service is the manufacturer standard — typically after every 150–200 hours of run time or once per year (whichever comes first). Service includes oil and filter change, spark plug inspection, battery check, and transfer switch test. Many generators also require 30-minute weekly self-tests — confirm yours is running them by checking the exercise schedule setting.

Common questions

Frequently asked questions in Miami, FL

My power went out and my generator won't start. What should I check first?

For portable generators: check the fuel level, oil level (low oil auto-shutoff is common), choke position, and that the outlet switch is on after the engine starts. For standby generators: check the circuit breaker on the transfer switch and that the unit's control panel shows 'Ready.' Most modern standby generators self-test weekly — if yours hasn't, it may have a fault code on the display.
