Standby generator installation on concrete pad next to brick home in Newton area

How a Whole-House Generator Protects Your Westwood Home

A standby generator is a permanently installed outdoor system connected to your home’s natural gas or propane supply and wired to your electrical panel through an automatic transfer switch.
When an outage occurs:

  • The Transfer Switch Detects the Loss: Monitoring your utility connection continuously, the automatic transfer switch recognizes the outage the moment it occurs.
  • The Generator Starts Automatically: Within approximately 10 seconds, the generator is running and delivering power to your panel.
  • Your Home Operates Normally: Lights, HVAC, refrigerator, security systems, and other loads continue running without interruption.
  • Everything Returns to Normal When the Grid Does: When utility power is restored, the transfer switch shifts your home back to the grid and shuts the generator down automatically.

You don’t touch a thing.

Westwood Generator FAQs

What's the right generator capacity for a typical Westwood home?

Capacity depends on your home’s size, the type and number of HVAC systems, and what level of coverage you want. Most mid-size Westwood homes fall in the 14kW to 20kW range for comprehensive coverage. Larger homes or those with electric heating, a pool, or EV charging may need more. We calculate your home’s specific load requirements before making a recommendation.

Can a standby generator run an EV charger during an outage?

Technically, yes — but including an EV charger in the generator’s load calculations requires specific capacity planning. If you have or plan to have an EV charger, we factor that into the generator sizing discussion so the unit is appropriately sized to cover both the charger and the rest of the home’s loads simultaneously.

What's the advantage of natural gas over propane for a generator fuel source?

Natural gas is connected to a continuous municipal supply line that isn’t interrupted during most storm events, meaning the generator can run indefinitely without any fuel management on your part. Propane requires tank monitoring and refilling, but is a fully capable alternative for homes without natural gas service. We help you evaluate both options based on your property’s existing fuel setup.

Can a whole-house generator power central air conditioning?

Yes, provided it’s sized appropriately. Central air conditioning is one of the higher-draw loads in a home, and it needs to be included in the generator sizing calculation. A properly sized Generac unit will handle HVAC, refrigeration, lighting, and other loads simultaneously.

How does annual maintenance work for a Generac generator?

Generac recommends annual service that includes an oil change and filter replacement, spark plug inspection, air filter check, battery load test, and overall system review. Proper maintenance is important for both reliable cold-weather starting and long-term system longevity. Castle Electric can connect you with qualified service providers.

Battery Backup and Integrated Power Systems for Westwood Homes

Standby generators remain the most powerful and reliable backup power solution for extended outages, but they’re not the only option. Whole-home battery storage systems provide clean, instant, silent backup power with no fuel requirement — ideal for shorter outages and an excellent complement to rooftop solar installations. For homeowners with compatible EVs, vehicle-to-home power technology allows the vehicle’s battery to support essential home circuits during an outage. Castle Electric designs and installs all of these technologies and can help Westwood homeowners think through which combination best serves their specific situation.

Install Before the Storms Come — Not After the First One Reminds You Why

Generator installations involve site assessment, equipment ordering, permitting, and the installation day. Demand peaks in September and October when storm season approaches and scheduling extends significantly. Westwood homeowners who call in spring and summer consistently have smoother installation experiences and are protected heading into winter rather than scrambling after their first significant outage of the season. If backup power is on your radar for this year, now is the right time to act on it.

Vehicle-to-Home Power for Westwood EV Owners

A growing number of compatible EVs — including the Ford F-150 Lightning and the Ford Escape Plug-In — support bidirectional charging that allows them to export power from their battery to your home during an outage. With the right inverter equipment and wiring installed by Castle Electric, your EV can serve as a portable backup power source for essential home circuits. This technology is still evolving rapidly, but Castle Electric can evaluate your vehicle’s compatibility and design the electrical infrastructure that makes vehicle-to-home power work in your Westwood home
