See how it works, step by step ↓The guide
Total installed cost typically runs $7,000 to $13,000, depending on system size and site. Here's what drives the number and how to choose who does the work.
01 · Why standby
Arizona's grid is under stress from record demand, aging equipment and volatile weather.
The generator comes on within seconds when it detects a power loss.
Rolling blackouts, monsoon outages and equipment failures now happen regularly.
Losing A/C in a Phoenix summer isn't just uncomfortable.
Factory-trained dealers, reliable engines and warranty coverage that holds up.
02 · Size and cost
Starts around $2,500. Enough for essential circuits.
Whole-home coverage, $5,500 and up.
$3,500 to $6,000 depending on electrical work, gas line routing and placement.
Surge protection, load management and service plans add $500 to $2,000.
03 · Pick an installer
Factory training and direct manufacturer support, not a rebadged general contractor.
Maricopa County permits, monsoon patterns and desert siting.
Itemized quotes, not one lump sum that hides scope decisions.
Recent, verifiable reviews, not just testimonials on the company's own site.
04 · Install
Good installers pull all required Maricopa County permits.
Final inspections are coordinated and usually included in the quote.
Longer gas runs or tricky placement cost more.
Years of dependable backup, honored warranties and resale value.
