Never Lose Power in a Fresno Outage Again

PSPS shutoffs, summer grid strain, and aging infrastructure mean Central Valley homes lose power more than most. A properly sized generator keeps your AC, well pump, refrigeration, and medical equipment running when it matters.

Apex Air, Heating & Electric handles the entire process — load calculation, permitting, PG&E coordination, installation, and inspection sign-off — for whole-home standby, portable, and commercial systems.

Critical Power Notice

Is Your Home at Risk During a PSPS Event?

If you're on medication that requires refrigeration, run a well pump, or live in a high fire-threat district, an unplanned outage isn't just an inconvenience. Fresno and Fresno County saw repeated Public Safety Power Shutoffs during peak fire season — most lasting 24 to 72 hours.

Medical & Refrigeration Risk

CPAP machines, refrigerated medication, and home dialysis equipment all fail without backup power within hours.

Well Pump & Ag Operations

No grid power means no well water and no irrigation control — a standby generator keeps pumps and VFDs running.

Fresno and the surrounding San Joaquin Valley depend on continuous power for cold storage, packing houses, and irrigation. Apex Air, Heating & Electric provides sized commercial and agricultural standby generator systems built around your critical load.

Frequently Asked Questions About Generator Installation

How much does a standby generator cost in Fresno, CA?
Most Fresno homeowners invest between $8,500 and $16,000 for a whole-home standby generator installation in 2026. A 16-22kW system — enough for most Central Valley homes — typically runs $8,500 to $13,000 installed, while a 24-38kW system for larger homes with air conditioning, EV charging, and well pumps on the essential load runs $13,000 to $18,000. Portable and manual-start backup systems run $2,500 to $5,000. Every Apex quote includes permit fees, PG&E coordination, the concrete pad, and a full 1-year workmanship warranty.
What size generator do I need for my house?
Generator size is set by a load calculation, not by square footage. We add up what you actually need to keep running — air conditioning, well pump, refrigeration, medical equipment, or a home office — and size the system to that load with the starting surge of large motors like compressors and pumps accounted for. Most Fresno homes land on a 16-22kW whole-home standby system; larger homes with AC, EV charging, and a well pump on the essential load need 24-38kW. We perform the load calculation as part of a free sizing assessment.
What is the difference between a standby and a portable generator?
A standby generator is permanently installed outside your home, runs on natural gas or propane, and starts automatically within seconds of an outage — it powers your whole home without you being there. A portable or manual-start system is a lower-cost option sized for essential circuits only; you start it and connect it through a manual transfer switch, which makes it a practical choice for renters and smaller homes.
Do you handle the permits and PG&E coordination for a generator install?
Yes. Apex Air, Heating & Electric handles the entire process from start to finish: the electrical load calculation, the City of Fresno or Fresno County permit application, PG&E coordination, the gas or propane fuel line run, installation, and final inspection sign-off. All work is performed by licensed electricians and permitted for inspection.
Do you service and maintain generators after installation?
Yes. Annual service plans include scheduled load-bank testing, oil changes, and battery checks, so your generator starts when you actually need it. A standby generator that has sat untested for two years is the most common reason a backup system fails during an outage. Apex Air, Heating & Electric maintains residential, commercial, and agricultural standby systems throughout the Central Valley.
Do you install commercial and agricultural generators in the Central Valley?
Yes. Apex Air, Heating & Electric designs and installs commercial and agricultural standby generator systems built around the critical load: cold storage and packing house refrigeration, irrigation and well pump systems paired with VFDs and pump controls, and light industrial facilities running equipment, security, and building systems. Commercial and agricultural projects are quoted from a load calculation and site evaluation.
