Frequently Asked Questions
What size standby generator do I need for my home?
Answer:
Calculate the total wattage of the essential appliances and systems you want to keep running (refrigerator, furnace, lights, sump pump, etc.). Most homes require 10 kW–20 kW for basic backup, while larger homes with HVAC, well pumps, and multiple circuits may need 25 kW–40 kW. Use a load‑calculation worksheet or consult an electrician to size the unit correctly—oversizing leads to higher fuel use, undersizing can cause overloads.
How often should a standby generator be serviced?
Answer:
– Monthly: Run the generator for 10–15 minutes under load to keep the engine lubricated and the battery charged.
– Quarterly: Inspect oil level, coolant, and air filter; replace oil and filter annually or per the manufacturer’s schedule.
– Annually: Have a qualified technician perform a full inspection, test the transfer switch, and check fuel quality (add fuel stabilizer if stored for long periods). Regular maintenance ensures reliability when you need it most.
