What residential generators involves

Backup power is a system. The engine is the part people shop for and the least of the problem. The work starts with finding out what is actually there. With residential generators, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

We explain the job in plain terms before anything starts: what we are changing, why, and how long the power will be off. If a smaller fix does the job, that is the fix you get.

Where this comes up

Standby generators, automatic transfer switches and emergency power systems. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

New load on old wiring is the most common version. A heat pump or a charger for the car goes in, the circuits that were fine until then start complaining, and the real question becomes whether the existing service can carry it at all.

How we do it

Licensed and insured on every call. No job is too small to do properly, and no shortcut is worth an inspector’s red tag. We would rather do it once.

Why it usually cannot wait

Electrical problems do not stay the same size. A loose connection heats up, the heat oxidizes the metal, the oxidized metal raises the resistance, and the resistance makes more heat. That loop runs in one direction only and it ends at a scorched box.

If something is tripping, buzzing, warm to the touch or smells like hot plastic, that is the system telling you where the problem is while it is still cheap to fix.

How we quote it

When there is more than one way to do the job, the quote says so. A subpanel or a new service, repair or replace: you see both options priced, with our honest read on which one your building actually needs.

No lump sums. Every quote is broken out so you can see where the money goes, and it is tied to a defined scope. When the scope holds, the price holds.

The inspection is the point

An inspection is an independent check that what went behind the drywall matches what was supposed to. Work that passes has been verified by somebody with no stake in the invoice.

That is also why we would rather you hire a licensed contractor than the cheapest number you can find. Unpermitted electrical work is a problem you inherit, and it usually surfaces at the worst moment.

Grounding and bonding

Grounding is the part nobody sees and the part that decides whether a fault clears safely. The ground path has to be continuous and low-impedance from every device back to the service, and the neutral and ground can only be bonded together in one place.

A neutral bonded to ground in a subpanel is one of the most common defects we find. It works right up until it does not, and then it puts current on metal that people touch.

When to stop and call

Stop and call when you see sparks from an outlet, smell burning plastic, or notice a cord or plug that has softened or melted. Turn off that circuit at the panel if you can do it safely.

A GFCI outlet that trips the instant you press reset is telling you something specific: there is a ground fault on that line right now. Do not bypass it or replace it with a regular outlet. Unplug everything downstream and call us.

The transfer switch is the system

People buy a generator and think of the engine as the product. The part that decides whether backup power actually works is the transfer switch, because it is what keeps generator power from backfeeding onto the utility line where it can kill a lineman.

Automatic switches sense the outage and start the unit without anybody being home. Manual switches cost less and need somebody present. Which one is right depends on what you are protecting.
