Standby Generators in Seattle
Reliable Generator Services Across
Western Washington
Power outages in the Seattle area, whether caused by strong winds, winter storms, or unexpected grid issues, can disrupt daily life and leave your home without essential comforts. A standby generator provides a reliable solution, automatically restoring power within moments of an outage to keep your lights on, heating, cooling, and electrical systems running, and food preserved. In other words, it keeps your household safe and comfortable when the main power goes out.
At Brennan Heating, Air Conditioning, Plumbing, and Electrical, we know how vital uninterrupted power is for your comfort and the smooth operation of your home. We install standby generators for homeowners across Seattle and Western Washington, from city homes to more remote properties. Our team can help you choose a system that fits your family’s needs and power demands, giving you confidence that your home will stay functional and comfortable, even during extended outages.

How Standby Generators Provide Automatic Power
Standby generators provide a hassle-free solution for electrical outages by automatically kicking in when the power goes out. Unlike portable generators that require manual setup, fueling, and connection during challenging conditions, a standby generator is permanently installed outside your home and constantly monitors your link to the utility grid.
The secret to this seamless operation is the automatic transfer switch (ATS). When the ATS detects a power outage, it disconnects your home from the grid within seconds and signals the generator to start. Once the generator produces stable electricity, the ATS switches your home's selected circuits (or the whole house, depending on the configuration) to generator power. When utility power is restored, the ATS reverses the process, reconnecting your home to the grid and shutting down the generator without you lifting a finger.
The Benefits of a Standby Generator for Your Western Washington Home
Adding a standby generator to your Seattle home offers peace of mind, especially during weather-related power outages caused by wind, snow, or falling trees. These systems do more than just keep the lights on—they help maintain your comfort, safety, and daily routine when unexpected outages occur.
A standby generator keeps vital home systems running without interruption, including heating and cooling systems (key for staying comfortable and avoiding frozen pipes in winter), refrigerators and freezers (preventing food spoilage), lighting, security systems, and medical devices. It also helps you avoid unnecessary expenses, maintain a safe and comfortable environment, and protect your household.
Knowing your home will have power during an outage allows you to focus on what matters most while minimizing disruption to your daily life.
Choosing the Right Standby Generator: Important Considerations
Finding the right standby generator for your Western Washington home means considering your power needs, property, and budget. At Brennan Heating, Air Conditioning, Plumbing, and Electrical, we can guide you through the options to find a dependable solution.
The most common types of standby generators include:
- Home standby generators: Ideal for residential use, these provide automatic power during outages and typically run on natural gas or propane.
- Inverter generators: Compact and quieter, these deliver cleaner power, making them ideal for sensitive electronics.
- Industrial generators: Larger units for businesses or big properties, often designed to handle greater power demands.
A key factor to think about is generator capacity (measured in kilowatts or kW), which determines how many appliances and circuits it can power at once. Smaller units can cover essential circuits, while larger models can provide whole-house power. Another consideration is the fuel type. Most residential generators use natural gas or propane. Natural gas offers a steady supply if your home is connected to a gas line, removing the need for refueling. Propane, stored on-site in a tank, is a good choice for homes without natural gas access or in remote areas.
