"Joel Smith and his coworkers did a fabulous job installing a generator for me before winter. They were exactly on schedule, all very polite and cooperative with what was going on in our schedule. The generator is top quality. His explanations of its functions and controls were clear. He and all his crew were exceptionally helpful to me, I recommend him highly."

"We were very happy with the work.Eric was easy to work with. He installed a new 220 circuit and was able to fish it though the walls harmlessly whereas other electricians we talk with were going to tear up the drywall. Pricing was very reasonable. Highly recommend."

Generator Install questions, answered by experts

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

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

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
