"Beacon came out, did an assessment and provided a quote for a generator based on my power consumption. They also provided recommendations based on my current setup ( pointed out things that were not up to code) and possible fix actions. Installation took 1 day and looked very professional. Follow up for the 1st year is part of the installation also. Overall, a great experience. Rated value a little lower simply because your paying a lot of money for something that may never be needed, but it's always nice to know it's there."

"My family and I just purchased this home and had no idea where the GFCI was to control the outlets. Technician was going to trace the power on a later date but hearing him say it was controlled tripped at a GFCI that my wife and I couldn't find gave me the idea to look behind boxes in the garage that need to be unpacked still. Found it to be tripped and outlets work. Overall the company is very kind people over the phone and in person and if I had a problem that couldnt be fixed from GFCI I would definitely hire them again."

Generator Install questions, answered by experts

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.
