In a Tucson summer, an outage isn’t just an inconvenience — a house without AC in July heats up fast, and a long outage puts a refrigerator full of food at risk. A standby generator with an automatic transfer switch handles that without anyone dragging a portable unit out of the garage. The job is sizing it honestly and wiring the transfer switch correctly.
Keep Your Power On with Standby Generator Services
A whole-house generator wires directly into your electrical system and starts on its own when the power drops. No extension cords, no dragging a portable unit out of the garage at 2 a.m. The AC, the refrigerator, the well pump and the lights stay on while the rest of the street waits on the utility.
Most Tucson installs are a standby unit on a concrete pad outside, fed by natural gas or propane, wired to an automatic transfer switch at the panel. We handle the electrical side start to finish — load calculation, transfer switch, permitting and inspection. And we tell you the size your home actually needs instead of selling you the biggest unit on the lot.
What We Handle
- Whole-house standby generator installation — sized to what you actually want running, not to the largest unit we could sell.
- Automatic transfer switch wiring — the safety-critical part of the job, and the reason this isn’t a DIY project.
- Load prioritization — a managed setup can run AC, refrigeration, and essential circuits on a smaller, cheaper generator.
- Fuel & siting coordination — natural gas or propane, placed with clearances and noise in mind.
- Permitting & inspection — handled as part of the installation.
- Panel work when required — some installs need panel changes first; we’ll tell you before you commit.

Sizing Is the Whole Decision
Generator quotes vary enormously, and most of that variation comes down to one question: what do you want running when the power’s out? “Everything, exactly as normal” is the expensive answer, especially in a climate where “everything” includes air conditioning. “AC in one zone, the fridge, the internet, and some lights” is a much smaller and cheaper machine.
Load management changes the math too. Rather than sizing the generator to the theoretical maximum of every circuit at once, a managed setup sheds lower-priority loads so a smaller unit covers what matters. That’s often the difference between two very different budgets.
Then there’s the transfer switch, which is the part that actually keeps people safe. It isolates your home from the utility so the generator can’t backfeed the grid — a real hazard to line workers and to your own equipment. It’s wired to code, permitted, and inspected, and it is not a corner to cut.

Pricing, Up Front
Tucson-area whole-house generator installations typically run about $4,750–$23,800 depending on generator size, fuel type, siting, and installation complexity. An essential-circuits setup with load management sits well below a whole-home-at-full-load system — which is exactly why the sizing conversation happens before the quote.

Generator FAQ
How big a generator do I need?
It depends on what you want covered during an outage. We’ll walk through that on the estimate visit and give you options at different sizes rather than one number.
Is this a DIY-friendly project?
No. Generator transfer switch wiring is licensed-electrician work for safety and code reasons — an improperly isolated generator can backfeed the utility line and endanger line crews as well as your own equipment.
Does it start automatically?
With an automatic transfer switch, yes — it detects the outage, starts the generator, and switches over without anyone home. Manual transfer switches cost less and require someone to be there.
Does a generator install need a permit?
Yes, in most cases — the electrical work and often the fuel and placement side as well. We handle the electrical permitting as part of the job.
