"I hired Rob Heiser to install 7 new light fixtures and a post light on my home's exterior. He also installed a path lighting system and a brush box on the outside of my house to connect outdoor speaker cables to my Sonance system. Rob and his sons did an excellent job and were extremely professional. He performed the job exactly as I asked and did a great job cleaning and organizing all the removed fixtures and trash before they left. I would highly recommend Heiser Electric."

Generator Install questions, answered by experts

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.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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. 

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
