How to maintain a standby generator

What this site is

Gen Size Desk helps homeowners (and light-commercial managers) ask better questions before buying or servicing a standby generator: load calculations by a licensed electrician, natural-gas vs propane ratings, transfer switches, permits, and basic maintenance cadence.

We summarize and link out. We do not invent reviews, warranties, or prices. Local code and your OEM manual win.
