"Scheduling for the bid was backed out a ways - and therefore delayed my project a little... but, as it turns out, I'm glad I waited the extra couple of weeks. Scheduling was otherwise very easy. Once I chose Peak, scheduling the work was a more reasonable wait. Everyone I dealt with was professional and communicated clearly from start to finish... they gladly answered any questions I had (I tend to ask a lot of questions). The work was well done. Electrician wasn't familiar with the particular brand of charger I had purchased, but was able to figure out everything that wasn't immediately obvious by just looking in the installation instructions provided. In hindsight, I probably could have handled the job (knowing what I know now)... but am definitely still glad to have had a licensed electrician do this work - which was required to be eligible for some utility and tax rebates anyway - and have the peace of mind that comes with it. I Received quotes/bids from multiple contractors... only one was potentially less - but it was lacking in details (permit costs, etc.) - and was about the same price for the things that were listed. I like to "shop union" when possible, so I was pleased that Peak was a Union shop... and, as an added benefit, had a $200 coupon through the Union (IBEW) - so it ended up being the least expensive bid overall. The price was reasonable for the work... and I paid exactly what was bid - not a penny more. I would not hesitate to hire Peak again for any electrical work I need done."

"I needed a Tesla charger installed in my garage. They showed up to the house quickly, and were very knowledgeable on what to do and what i needed. They installed it within an hour, with very quality parts, and were very neat and tidy about it too. No issues since install! I definitely would consider them again in the future!"

Generator Install FAQs, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

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. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.
