How does home standby generator installation work?

A typical installation includes: site evaluation, load calculation, permitting, pad prep, fuel connection, ATS wiring, commissioning, and final inspection.

What is a home standby generator?

A standby generator is a permanently installed unit that automatically powers your home during outages. It’s wired into your panel with an Automatic Transfer Switch (ATS).

Why should I buy a home standby generator instead of a portable generator?

Standby generators are safer, automatic, and power your whole home without the hassle of refueling or running cords. They’re fully code-compliant and permanent solutions.

What is an automatic backup generator?

An automatic generator detects outages and switches on within seconds, keeping essential circuits or your entire home powered without manual intervention.

How does an automatic generator know when to turn on?

The system constantly monitors utility power. When it senses a failure, it automatically starts and transfers your home to generator power via the ATS.

What types of fuel do automatic generators use?

Most standby units run on natural gas or liquid propane (LP). Fuel type depends on your home’s access and preference, but both are safe and reliable options.

Can a generator power my whole home?

Yes — with the right sizing. We perform load calculations to determine whether you need full-house coverage or just essential circuits like HVAC, refrigeration, and lighting.

How often should a generator be maintained?

We recommend at least an annual service. This includes oil/filter changes, battery checks, and load testing. We offer annual and bi-annual maintenance plans.

Will an automatic generator add value to my property?

Yes. Standby systems are attractive to buyers, increase home resilience, and often improve property value — especially in areas with frequent outages.

How do I correctly size a generator for my home?

We perform a load calculation during your free assessment to determine the right size based on your appliances, HVAC, and critical circuits. Proper sizing ensures efficiency and reliability.
