How Do Whole-House Generators Work?

Sometimes called a fixed standby generator, a whole-house generator is installed permanently outside your home on a concrete pad in your yard. Whenever there is a power outage or equipment failure, the whole-house generator will automatically provide power straight to your home’s electrical panel, even if you’re not home. 

An automatic transfer switch disconnects you from your utility as soon as service is interrupted. An internal combustion engine powers the system. The generator can energize your home nonstop for days. When power is restored, the generator returns to standby mode, ready for the next power outage.

What Makes them Different from Portable Generators?

Whole-house generators offer higher power levels than portable generators and have the added convenience of automatic power. Portable generators are typically used in camping, tailgating, job sites, and other outdoor activity scenarios. These types of generators are mobile and can power individual items, such as appliances and lamps. You can turn them on and off as needed. 

Whole-house generators are permanently installed outside and supply power to your entire home. You have nothing to do with turning them on and off – they work automatically, reacting to your home’s need for power. Unlike the portable generators, which run on gasoline or diesel you provide, whole-house generators are fueled by your home’s existing fuel supply, such as natural gas, liquid propane (LP), or diesel. And because they are permanent appliances, they have the added benefit of adding value to your home. 

The Average Cost of a Whole-House Generator

Whole-house generators can cost anywhere from $3,000 to $20,000, depending on the size needed. To determine your home’s ideal generator size, you need to assess your needs during a temporary emergency. Do not include powering all of the appliances in your home in your assessment. 

You should also include the cost of regular maintenance and fuel to run the generator when making a total estimation. Like any other system, there is always some upkeep involved. Be sure to get your generator serviced by a professional after 24 to 48 hours of continuous use. The oil and filter should be changed after about ten days or so. Keep your generator healthy by checking its oil level daily during use and running it at no more than 75 percent of its rated capacity. Also, be sure to replace overworked or broken parts, such as brushes. Keeping up with this type of maintenance will ensure your generator will have a long and useful life. Remember that if you ever decide to resell your home, a whole-house generator significantly adds to its value, so you could eventually recoup much of your initial investment. 

Our Generator Installation Process

At Chesterfield Service, we strive to make the generator installation process as seamless and straightforward as possible for our clients. Our process begins with an initial consultation, where we assess your home's specific power needs and discuss your preferences. This step helps us recommend the most suitable generator for your household. During this consultation, our experienced technicians will also evaluate your home's layout, existing electrical system, and any other factors that could influence the installation.

Once the generator has been chosen and all preparations are in place, our skilled technicians will handle the installation with precision and efficiency. We position the generator in an optimal location outside your home, making the necessary connections to your electrical system while complying with all local regulations and codes. Our team will also conduct thorough tests to verify the system's readiness and performance. Finally, we provide a comprehensive tutorial on operating and maintaining your new generator so you feel confident putting your new backup power system to good use.
