Generator Installation near you in Phoenix and the salt river valley
Whole House Generators Installed by Licensed Electricians
Having a standby generator can be a lifesaver during major city outages, especially during Phoenix’s notorious monsoon season. But knowing how much power you’ll need, let alone the brand or model of generator to purchase, isn’t always easy. That’s where Patrick Riley comes in. We make choosing the right home backup generator straightforward with free in-home consultations, honest recommendations, and upfront pricing. We’ll even help you pay for your new generator with a variety of low-interest financing options.

A whole house backup generator installation is more involved than buying a unit and plugging it in. Sizing, fuel type, and the electrical work needed to connect it to your home all affect both the cost and how well the system performs when you need it. Our home generator installers handle every part of the job in Phoenix, from the initial recommendation through the final connection.

Factors That Affect the Cost of Your Home Backup Generator Installation
A few key factors determine what your specific generator installation will cost. Here’s what goes into that number:
- Number of kilowatts: Which backup generator you choose has a lot to do with how much power you need. Generator power is measured in kilowatts (kW), and a standard home typically needs a generator somewhere in the 20kW to 50kW-plus range, depending on the size of the home and appliance use. The higher the kW, the more your generator installation will cost.
- Fuel type: A standard gasoline generator is the most affordable option on the market today. Natural gas generators cost a bit more but offer the convenience of connecting directly to a natural gas line already running to your house. Diesel generators are also available and tend to have higher installation costs than other options.
- Electrical modifications and upgrades: For a new installation, additional gas lines and electrical wiring often need to be run between your home and the generator. These modifications add to the overall cost of the project, and a technician can walk you through what your specific home will need.
Frequently Asked Questions
What does a standby generator power during an outage?
Whatever it is sized and wired to carry, from essential circuits like the refrigerator and cooling to the entire home. The transfer switch and load plan set the scope, and that gets decided in the design stage.
Why does backup power matter in a place with mild winters?
Because Phoenix outages cluster in summer, when monsoon storms hit the grid and losing cooling is a safety issue rather than an inconvenience. A standby unit restores power automatically, whether you are home or not.
What fuel do home standby generators use?
Most run on natural gas or propane, drawing from the home’s gas line or a tank, so there is no refueling during an outage. That is the main difference from portable units.
Where can a generator be installed on my property?
On a pad outside the home, with clearances from windows, doors, and property lines set by code and the manufacturer. Placement also considers the gas and electrical runs, which shape the install.
Does a standby generator need maintenance?
Yes. Like any engine, it needs periodic oil, filter, and battery attention, plus exercise cycles to confirm it will start when the grid drops. A unit that sits untested is the one that disappoints during a storm.
