"Tom did a fabulous job with the whole house plug installation for my back up generator. He was quick and efficient and cleaned up well after the work. He explained how to use the plug and manual interlock and made sure everything worked before leaving. Quality job on all fronts. Pricing was fair and he was able to fit me in on short notice due to another job rescheduling. I will definitely contact him again should the need arise."

"I couldn't have asked for a better service person. Alex came for consultation on my electric hot water heater replacement. He quickly diagnosed and fixed the problem and told me my water heater is fine. He is a true professional. He was very kind, pleasant and courteous, and gave me useful information about water heaters and installation issues in general. When my 10-year-old water heater quits for good, I know where to go. Thank you for the great work!"

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

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

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.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

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.
