A&G Heating & Air
Standby Power at the Edge of the Sierra
Porterville sits where the valley meets the foothills, and homes on the eastern side of town live with the outage exposure that comes with it. A&G Heating & Air installs backup generators in Porterville built to carry a house through outages that last longer than a few minutes.
Foothill-adjacent service areas typically wait longer for restoration than dense urban grids. That changes the calculation: you need a generator that can run at load for an extended period, with a fuel supply sized to match, not a stopgap that covers a brief flicker.

We begin with a measured load calculation covering air conditioning tonnage, heating equipment, refrigeration, well pumps where present and any large discretionary loads.
From there we recommend either a whole home backup generator or an essential-circuits configuration, and we explain precisely what each will carry during a summer afternoon outage versus a winter storm.

Generator installation in Porterville requires electrical and mechanical permits and code-compliant setbacks from windows, doors and property lines. We handle the permitting, set the pad and coordinate the fuel connection.
After the automatic transfer switch is tied into the panel, we load-bank test the system, program the weekly self-test and walk through the maintenance schedule before final inspection.
Porterville's summers are hot and its foothill winters can be cold, so both heating and cooling belong in the plan. A&G provides air conditioning and heating services locally, which means the generator can be sized against your exact equipment.
