"Justin did great job, intalled the hookup and the transfer switch for the portable generator. Worked in freezing temperature outside. The only downside was that the install was postponed few times because he was waiting for the parts"

"Justin was awesome. Very proactive about calling me back and he was able to squeeze me in right away. He was also very flexible about the job. There were a couple things I had asked him specifically to do and then I asked for an additional outlet to be installed...he did it no problem. Great Experience!"

"When I hired AEC to install a new central A/C system, they told me it would take a week. Started Monday, finished Friday, right on schedule. There was an issue where it did not start up the first time I went to use it 2 weeks later, but they promptly came out and repaired the loose wire."

Generator Install FAQs, answered by experts

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

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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

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.
