Which Generator Is Right For You?
People often find themselves stuck when it comes to choosing between portable generators and whole-house generator installations in Snohomish County.
- UPortale Generators
While portable generators serve well for temporary outdoor needs, they fall short in providing comprehensive home power. Limited in capacity, they risk overheating and can’t support the full spectrum of a home’s electrical demands. - Whole-house generators
These offer a robust, permanent solution, ensuring uninterrupted power supply to your entire home, regardless of your presence. Their installation not only guarantees continuous operation of all appliances during outages but also contributes to an increase in your property’s value. If you need help deciding which generator is right for you, our team is happy to help.
Automatic Activation, Seamless Transitions
Whole-house generators detect power interruptions through an automatic transfer switch, swiftly switching your home’s power source from the utility to the generator. Fueled by your home’s natural gas line, these generators ensure your home remains powered for extended periods. Once utility power is restored, the generator seamlessly transitions back to standby mode, ready for the next outage.
Trust in ONESTOP for all your whole-house generator installations in Snohomish County, ensuring your home or business remains powered, safe, and comfortable, no matter the weather or situation.
