A backup generator is worth it in Miami if an outage would cost you more than the generator does — spoiled food, a house without air conditioning in August, or medical equipment that can't go dark. Portable generators cover the essentials for less money; standby generators power the whole house automatically but cost more. The questions below are the ones homeowners ask before they buy, in the order that matters.

Why would I need one?

Power outages in Miami are a matter of when, not if — hurricane season and summer storms take the grid down every year, and the utility's service can be interrupted for hours or days. A generator keeps the refrigerator cold, the lights on, and the air conditioning running through the outage, and it keeps a home office or medical equipment working when the grid cannot. For a house with anyone who depends on powered equipment, it is not a luxury.

Portable or standby — which fits my house?

Portable generators cost less and suit short outages: you set them up, fuel them, and run extension cords to the essentials. They only power a limited number of appliances, and they need you there to run them. Standby generators are installed permanently, start automatically when the power drops, and can power the whole house, including the air conditioning — which is why they fit homes where outages last longer. The choice comes down to budget, how long outages usually last at your house, and whether someone needs to be home to start the generator.

How do I pick the right size?

List what must stay on — refrigerator, freezer, medical equipment, air conditioning, a few lights — and add up the running watts from each appliance's label. Then add the starting watts for anything with a motor, since motors draw far more power for a few seconds when they start. That total is the size you need; a generator smaller than that will overload and shut down, and one far larger wastes fuel and money. A licensed electrician can check the math against the panel.

What does installation involve?

Three things matter most. Location: the generator sits in a well-ventilated area, away from windows and doors, so exhaust never drifts inside. The transfer switch: a switch or interlock connects the generator to the house safely and prevents backfeeding the grid, which endangers utility workers. And professional installation: a standby generator is permitted electrical work under local codes, and it must be installed and inspected by a licensed electrician. The local climate matters too — humidity and salt air corrode outdoor equipment faster here, so the installation should protect connections from moisture.

What maintenance does it need?

Like a car, a generator needs regular care to work when it is needed. Run it for about thirty minutes every month so it stays in working order. Keep enough fuel stored for an emergency, and remember gasoline has a shelf life. And schedule an annual inspection with a licensed electrician, who can catch the small problems — a worn belt, a corroded connection, a weak battery — before they become a failure during a storm.

How do I know it needs attention?

Three warning signs say the generator needs a professional look. Unusual noises point to a mechanical problem. A generator that fails to start when it is needed is telling you something is already wrong. And frequent overloads — the generator tripping because the load is too big — usually mean it was never the right size for the house.

Quick FAQ

Can I run a generator indoors or in the garage?

Never. Generators produce carbon monoxide, which is colorless, odorless, and deadly. Run a generator outdoors only, well away from windows and doors.

Will a standby generator power my whole house?

Yes, if it is sized for the whole house — including the starting watts of the air conditioning. A generator sized only for essentials will not suddenly cover the rest of the house.

Do I need a permit for a standby generator?

Yes. Installation is permitted electrical work and must meet the Florida Building Code and Miami-Dade County amendments, with an inspection at the end. Your electrician handles the permit as part of the job.
