"Jeff and his team did an amazing job for my home renovation. They rewired an entire floor, removing then installing all new outlets, wiring for mini-splits, televisions, fixtures, fire/co2 detectors and a new electrical panel. They installed three wall mounted televisions, numerous lighting and fan fixtures with ease. Josh was a beast, crawling around in the attic and getting our new bathroom vents in and making sure all the switches worked together. They put in some late hours to make sure the job was done right. I would highly recommend Jeff and his team for your electrical needs."

Generator Install questions, answered by experts

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

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.

While natural gas generators are costly, they’re a great option for standby power due to the reliability of natural gas as a fuel source. Unlike other fuels, natural gas is delivered through underground pipes, making outages extremely rare and less likely to be affected by the elements. As long as the area isn’t prone to earthquakes, they offer an unlimited supply of natural gas that doesn’t degrade over time or require storage in tanks.

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

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup.
