"Los Gatos Electric provided a great turn key operation. Jim coordinated delivery of the replacement generator, also coordinated enlarging the cement pad and installation of the unit. He replaced my 25 year old generator with a Generac Generator. And hooked it up to the existing automatic switching panel which saved me time and money. Overall, I thought it was an excellent effort."

Finding a licensed electrician that you can trust to service or repair your property can be difficult. While some electricians offer free consultations or other specials, they often do not have the skills or expertise necessary to efficiently perform the service you need.

Generator Install questions, answered by experts

When installed and used correctly, generators are safe to use. The most critical generator safety tips to keep in mind are:

  • Never use a portable generator inside an enclosed space, as the carbon monoxide exhaust it creates is lethal.

  • Never attempt to connect your generator to your home’s electrical panel independently; hire a professional for this dangerous job.

  • Never overload your generator by connecting more appliances than for which it’s rated; you can damage your generator and appliances or even cause a fire.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home’s value, especially in areas prone to extreme weather and power outages.
