"After putting in a request on Home Advisor, Mike responded very quickly. I advised him i wanted to install a transfer switch for a generator and he went through the steps of what would need to be done. He asked a few questions, asked for a picture of the junction box, and then gave me a very reasonable quote. The day of the install, he called to reconfirm our appointment. The install was quick and clean."

"Fast and super helpful. Gave me a proposal right away. Started work same week. If deviations were needed, was specific on what and why. Reasonable and fair pricing, and honest about their capabilities and areas of expertise. Professional team and went out the way to provide additional references for other concerns. I also appreciated the video Fabio took to show me the before and after, especially in areas I was unable to see."

Generator Install FAQs, answered by experts

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.

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.

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

Many services include assembling the unit and securing it in the window. Confirm with your provider.

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.
