Whole Home Standby Power for Atwater Households
Atwater's housing stock spans mid-century homes and newer subdivisions, and both share the same vulnerability when the grid drops on a hot afternoon. A&G Heating & Air installs whole home backup generators in Atwater sized to each home's measured load.
A standby generator is not a portable unit with cords. It is permanently installed, wired to an automatic transfer switch, and it starts on its own when utility power fails — including at two in the morning when nobody is awake to notice.

Older Atwater homes often have single HVAC systems and modest panels, while newer construction carries heavier cooling loads. The load calculation resolves which category yours falls into and what capacity it requires.
We also check panel condition before quoting. A transfer switch has to be tied into a panel that can safely accept it, and we would rather tell you that at the survey than mid-project.

We pull the electrical and mechanical permits, verify setback distances from windows, doors and property lines, set the pad and coordinate the natural gas or propane connection sized for full-load run time.
The automatic transfer switch is installed at the panel, the system is load-bank tested, the weekly self-test is programmed and we complete final inspection before handing it over.
Clean, stable power protects the air conditioning and heating equipment you already own. Since A&G handles heating and air conditioning services in Atwater, we can size the generator against your specific system and coordinate the work in one project.
