Keep Your Home Powered with a Whole Home Generator
Ice storms, summer storms, heat waves—extreme weather has been known to knock out power in the Portland region. A whole-home generator helps you keep the lights on and your home comfortable, no matter what Mother Nature throws our way!
Unlike a less-powerful portable generator, a whole-home generator is designed to power your kitchen appliances, HVAC systems, lights, and electronics. It’s hooked up to a natural gas line or propane fuel, and is set up to turn on automatically when the power goes out.
Give the Watts team a call to get a consultation on the best whole-home generator option for your property.
Watts has always been good to me. They have honest and very kind staff. They come out as fast as possible and treat you like it’s their own family that needs assistance. Amazing staff, owner and company – they’re the best in the area. They are the best of the best! Thank you, Watts!

Generator Frequently Asked Questions
What size generator do I need? Can a generator power my entire home?
The size of the generator you need depends on what you want to power during an outage. If you only need to run essentials like a refrigerator, sump pump, and a few lights, a smaller portable generator (around 5,000–7,500 watts) may be enough. For partial home backup or high-powered appliances like central AC units, you might need a standby generator rated between 10,000–20,000 watts or more. For a full home backup solution, our technicians can help you assess your home’s needs to determine your ideal generator size.
How are full home generators powered?
Whole-home generators typically run on natural gas or liquid propane (LP). These fuel sources are connected directly to your home’s existing utility lines or a dedicated fuel tank. The automatic transfer switch detects outages and signals the generator to start within seconds—keeping your home powered without needing to turn the generator on manually.
How loud is a home generator?
Most residential standby generators are designed to operate quietly and are comparable in sound to a central air conditioning unit—typically around 60 to 70 decibels from 20 feet away. Many Honeywell generator models offer Whisper Check™ mode, which enables the generator to run at a lower RPM during routine test cycles. This makes for a quieter generator that consumes less fuel.
What generator brands do you represent?
We offer installation of Honeywell powered by Generac whole-home generators, and we offer the repair and maintenance of Honeywell and Generac generator models.
