"I have been hiring Cody Malone since we purchased our house in July 2012. They have switched out outlets, installed indoor ceiling fans, installed outdoor ceiling fans, ran electrical to my outdoor water feature and switched out my light fixtures. I plan to hire them again when I add electric to my detached garage. They always do a great job and arrive when they say they will. I have never had a single issue and they have been to my house for no less than six different projects!"

"The guys arrived exactly at the prearranged time. They informed me that the work would take longer than the '2 man hours' that I bought through the Angie's List Deals before they began the job - which I appreciated.  They were on task and professional the whole time. They explained any problems they encountered while re-installing the old light fixture - need new bulbs.  They cleaned up any mess they made at the end of the job. Rates and cost of supplies were reasonable.  I WILL BE CALLING THEM BACK FOR ANY OTHER ELECTRICAL WORK IN THE FUTURE.

"I was very impressed with this company from beginning to end. When they gave me an estimate, they spent 90 minutes with me to make sure I selected the right furnace and AC. The crew came two days later and installed the furnace and AC in one day. Great job! Very happy with the whole experience. I highly recommend this company to others."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

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.

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.

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.
