"We had a great experience working with Byron, during our home renovation. He didn’t just come in and do the electrical work, he took the time to offer thoughtful input that really helped us plan out our lighting and make decisions we’re very happy with. He was knowledgeable, professional, easy to communicate with, and incredibly easy to work with around our renovation schedule. Having someone who was flexible, dependable, and willing to share his expertise made the whole process so much easier. We’re very pleased with the finished work and would absolutely recommend him to anyone looking for a knowledgeable and reliable electrician. We’ll definitely be calling him again for future projects!"

"He received the notice early on Saturday morning and called within an hour. He was at my house to get the estimate done an hour after that. We agreed to have the install done the following Friday to give him time to get the permits done. He and his son we exactly on time and the price was actually lower than I anticipated. A totally professional job. This guy is on my list for my next electrical job."

Generator Install questions, answered by experts

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.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.
